COMPARATIVE TRANSCRIPTOME PROFILING OF MOMORDICA COCHINCHINENSIS (LOUR.) SPRENG. ARIL USING OXFORD NANOPORE AND ILLUMINA SEQUENCING TECHNOLOGIES
type: item
description: Gac (Momordica cochinchinensis (Lour.) Spreng.) is a tropical fruit recognized for its exceptionally high carotenoid content, particularly lycopene and β‑carotene. Although Gac possesses significant nutritional and pharmacological value, genomic and transcriptomic resources for this species are limited. Previous studies utilizing Illumina RNA‑Seq established the first de novo transcriptome of Gac aril, identifying over 81,000 unigenes and key enzymes involved in carotenoid biosynthesis. In this study, we generated a transcriptome of Gac aril using Oxford Nanopore Technologies (ONT) direct RNA sequencing and compared its assembly and annotation with the published Illumina dataset. ONT sequencing produced over 13 million long reads, resulting in 52,755 unigenes with an average length of 777 bp and an N50 of 922 bp, which are substantially longer than those generated using Illumina sequencing (average 388 bp, N50 450 bp). Functional annotation identified 33,235 unigenes with significant matches, including full-length carotenoid-related unigenes, e.g., phytoene synthase (PSY), phytoene desaturase (PDS), zeta-carotene desaturase (ZDS), zeta-carotene isomerase (Z-ISO), prolycopene isomerase (CRISTO), lycopene ß-cyclase (LCYB), and lycopene ε-cyclase (LCYE). Long-read ONT sequencing enabled the recovery of full-length transcripts, reducing assembly fragmentation and redundancy and yielding a more compact, biologically representative unigene set. While Illumina technology remains superior in sequencing accuracy and quantitative profiling, ONT offers enhanced structural resolution, isoform discovery, and the potential to detect RNA modifications. Recent advances in ONT chemistry, flow cell design, and bioinformatic pipelines are rapidly improving accuracy and throughput, establishing ONT as a credible stand‑alone approach for transcriptome analysis in non‑model plants. These findings demonstrate that ONT sequencing can reveal novel regulatory features of carotenoid biosynthe…

INVESTIGATION OF THE VARIATION OF GYMNEMAGENIN CONTENT IN GYMNEMA R.BR UNDER THE INFLUENCE OF CERTAIN STRAINS OF BACTERIA
type: item
description: The capacity of Lactobacillus casei, Lactobacillus rhamnosus, Bifidobacterium bifidum, and Bacillus subtilis to increase the content of gymnemagenin in Gymnema spp. R.Br was investigated on two samples of G. sylvestre and two samples of G. latifolium by incubating these samples for 8 days with each strain of bacteria. The difference in content of gymnemagenin before and after incubation was determined by using a validated HPLC method meeting all requirements of AOAC International on analytical method performance. The four strains of bacteria were found to increase the content of gymnemagenin in the tested samples after incubation, but the change caused by B.subtilis was not statistically significant. No significant strain-to-strain difference in the capacity to improve the content of gymnemagenin was found among the four strains of bacteria.

NEUROPROTECTIVE EFFECTS OF TIANMA GOUTENG DECOCTION IN A MIDDLE CEREBRAL ARTERY OCCLUSION MODEL OF ISCHEMIC STROKE
type: item
description: This study aimed to evaluate the neuroprotective effects of Tianma Gouteng Decoction (TGD) in a middle cerebral artery occlusion-and-reperfusion (MCAO/R) model. Neurological scores, body weight changes, and cerebral infarct volume were evaluated. In addition, the concentrations of gastrodin, baicalin, 2,3,5,4′-tetrahydroxystilbene-2-O-β-D-glucoside (THSG), and geniposide in the TGD extract were analyzed by HPLC to characterize its chemical composition. The results indicated that TGD at 13.7 g/kg (raw herbal materials) significantly attenuated MCAO/R-induced cerebral infarction, improved neurological deficits, and attenuated body weight loss compared with the vehicle-treated group. TGD at 6.8 g/kg (raw herbal materials) also conferred neuroprotective effects, with early functional improvement observed 24 h after reperfusion, whereas TGD at 27.4 g/kg (raw herbal materials) did not produce significant protection. The TGD extract contained gastrodin (1.4 mg/mL), baicalin (10.091 mg/mL), THSG (0.0203 mg/mL), and geniposide (9.023 mg/mL), which may collectively contribute to its pharmacological activity. Overall, these findings demonstrate that TGD exerts neuroprotective effects against transient ischemia-induced brain injury, with optimal efficacy observed at 13.7 g/kg (raw herbal materials), suggesting its potential as a promising therapeutic candidate for ischemic stroke.

ANTI-INFLAMMATORY EFFECTS OF THE BARK OF PHELLODENDRON AMURENSE RUPR. IN EXPERIMENTAL MODELS
type: item
description: The objective of this study was to investigate the anti-inflammatory properties of n-hexane, ethyl acetate (EtOAc), dichloromethane (CH2Cl2), and aqueous extracts of Phellodendron amurense. The activity was evaluated in vitro by nitric oxide (NO) and prostaglandin E2 (PGE2) inhibition assays, and in vivo using carrageenan-induced paw edema and lipopolysaccharide (LPS)-induced endotoxemia models in rats. In vitro anti-inflammatory activity was assessed by measuring the inhibition of NO and PGE2 production using RAW 264.7 macrophage cells. Among the tested extracts, the CH2Cl2 extract exhibited the most potent activity, with IC50 values of 10.88 ± 2.88 µg/mL for NO inhibition and 10.82 ± 1.22 µg/mL for PGE2 inhibition, followed by the aqueous extract, which also inhibited NO and PGE2 production without causing cytotoxicity. The CH2Cl2 extract of P. amurense (CPA) was orally administered to rats in both LPS-induced endotoxemia and carrageenan-induced hind paw edema models. In the endotoxemia model, CPA significantly improved survival and markedly reduced serum IL-6 and IL-1β levels, as well as white blood cell counts. Consistently, in the carrageenan-induced paw edema model, CPA significantly suppressed edema formation, reducing paw-volume increase by 36%, 48%, and 55% at 2, 3, and 4 h, respectively, compared with the carrageenan control group (p < 0.05).

EVALUATION OF MEMORY-ENHANCING EFFECTS OF MORINDA OFFICINALIS HOW. ROOT EXTRACTS IN A TRANSGENIC hAPP DROSOPHILA MODEL OF ALZHEIMER’S DISEASE
type: item
description: This study aimed to evaluate the memory-enhancing effects of the 50% ethanolic extract and four fractions (aqueous, n-butanol, ethyl acetate, and n-hexane) from Morinda officinalis How. (MO) roots using a transgenic hAPP Drosophila model of Alzheimer’s disease. Screening of acetylcholinesterase (AChE) inhibitory activity showed that both the ethanolic and four fractions exhibited inhibitory effects, with the n-hexane fraction demonstrating the strongest activity. In the learning memory assay using Drosophila larvae, the ethanolic extract and three fractions (n-butanol, ethyl acetate, and n-hexane) improved odor memory more effectively than the aqueous fraction. Further assessments of locomotor activity and survival ability identified the ethanolic extract and n-butanol fraction as the most promising candidates. Moreover, the ethanolic extract showed antioxidant ability by significantly decreasing the concentration of MDA in the head homogenates of adult flies. These results suggest that MO extracts, especially the ethanolic extract and n-butanol fraction, have potential memory-enhancing and neuroprotective effects in a transgenic Drosophila model of Alzheimer’s disease.

ACUTE ORAL TOXICITY AND LAXATIVE EFFECTS OF PHARBITIS NIL (L.) CHOISY SEED EXTRACT
type: item
description: The present study aimed to investigate the acute oral toxicity and evaluate the laxative effect of Pharbitis nil (L.) Choisy seed extract in mice. Acute oral toxicity of the extract was assessed in Swiss albino mice using the Karber-Behrens method to determine the LD50 value. The laxative effect was evaluated in loperamide-induced constipation and normal mice through fecal water content, number and morphology of fecal pellets, intestinal charcoal transit ratio, amount of retained feces in the colon, and gastrointestinal fluid secretion. The results showed that the P. nil seed extract exhibited low acute oral toxicity (LD50 = 3.96 g/kg). In the loperamide-induced constipation model, the extract at doses of 150 and 300 mg/kg significantly increased fecal water content compared with the constipation model group, exhibiting effect comparable to the reference drug bisacodyl (1 mg/kg). At a dose of 300 mg/kg, this extract significantly enhanced intestinal motility, comparable to bisacodyl (1 mg/kg), by increasing the intestinal charcoal transit ratio. The extract at doses of 150 and 300 mg/kg also reduced fecal retention in the colon. In normal mice, the extract at both doses, 150 and 300 mg/kg, increased fecal water content and the weight of intestinal contents, indicating stimulation of fluid secretion into the intestinal lumen. In conclusion, the P. nil seed extract exhibited significant laxative properties in a loperamide-induced constipation mouse model, providing scientific evidence supporting the use of this medicinal plant in the management of constipation.

ANTIOXIDANT, ANTIHYPERGLYCEMIC, AND RENAL PROTECTIVE EFFECTS OF HIBISCUS TILIACEUS L. LEAF EXTRACT ON STREPTOZOTOCIN-INDUCED HYPERGLYCEMIA
type: item
description: Hibiscus tiliaceus L. (Malvaceae) plays a significant role in traditional medicine for treating various diseases. This study aimed to quantify the total polyphenolic and flavonoid contents and evaluate the antihyperglycemic and renal protective effects of H. tiliaceus leaf extracts using in vitro assays (DPPH and α-glucosidase inhibitory activity) and a streptozotocin (STZ)-induced hyperglycemic mouse model. The results showed that the total phenolic and flavonoid contents in the aqueous extract (27.67 mg GAE/g and 11.01 mg QE/g) were lower than those in the 45% ethanol extract (31.67 mg GAE/g and 15.64 mg QE/g). Furthermore, the ethanol extract demonstrated superior antioxidant activity (IC50 value of 5.75 μg/mL) and α-glucosidase inhibitory activity (IC50 value of 2.69 μg/mL) compared to the aqueous extract (IC50 value of 21.05 μg/mL and 7.71 μg/mL, respectively). Oral administration of the 45% ethanol extract at 1.33 g/kg for 14 days significantly reduced fasting plasma glucose and improved glucose tolerance in STZ-induced mice. This dose also attenuated the oxidative stress marker malondialdehyde (MDA) in the kidneys while significantly enhancing endogenous glutathione (GSH) levels. These findings suggest that the H. tiliaceus leaf 45% ethanol extract is a potential candidate for managing hyperglycemia and preventing diabetic kidney disease.

OPTIMIZATION OF THE EXTRACTION PROCESS FROM YELLOW CAMELLIA FLOWERS (CAMELLIA CUCPHUONGENSIS NINH & ROSMANN) COLLECTED IN PHU THO PROVINCE USING RESPONSE SURFACE METHODOLOGY
type: item
description: This study was conducted to optimize the simultaneous extraction of total polyphenol content (TPC) and total flavonoid content (TFC) from the flowers of the yellow Camellia (Camellia cucphuongensis Ninh & Rosmann) collected in Phu Tho province. A Central Composite Design (CCD) combined with Response Surface Methodology (RSM) was employed to evaluate the effects of three independent variables: ethanol concentration (EtOH, 30-70%), extraction temperature (40-80°C), and extraction time (2-8 h). The optimal extraction conditions were identified as 58% EtOH, a temperature of 60°C, and an extraction time of 8 hours. Under these optimized parameters, the experimental values for TFC and TPC were 18.09 ± 0.17% and 35.12 ± 0.28%, respectively, which showed high compatibility with the predicted values. This optimized process provides a reliable scientific basis for the standardized production of bioactive-rich extracts from C. cucphuongensis. These findings highlight the potential of this endemic species as a high-value raw material for the development of antioxidant-based pharmaceuticals and functional foods in the field of natural products chemistry.

AZAPHILONE DERIVATIVES ISOLATED FROM ENDOPHYTIC FUNGUS PENICILLIUM SCLEROTIORUM
type: item
description: Endophytic fungi are one of the typical endophytic microbial groups that have recently attracted considerable research interest because of their roles in many aspects. The most special thing is the ability to biosynthesize secondary substances with biological activity, such as antioxidant, anti-microbial, anti-tumor, and anti-inflammatory effects. The endophytic fungal strains were first isolated from Acorus gramineus herbs and identified as Penicillium sclerotiorum by morphological, microscopic, and DNA sequencing based on the modified Sanger method. From the ethyl acetate fraction of the medium extract, six compounds were isolated and identified as peniazaphilones I (1), 11-epi-geumsanol F (2), sclerotioramine (3), epi-isochromophilone III (4), isochromophilone IV (5), and linoleic acid (6). Their structures were determined by means of spectroscopic methods (MS, 1D, and 2D NMR).

CHEMICAL COMPOSITION, ANTIMICROBIAL AND CYTOTOXIC ACTIVITIES OF THE LEAF ESSENTIAL OIL OF KNEMA GLOBULARIA (LAMK.) WARB. FROM THANH HOA, VIETNAM
type: item
description: This study reports the chemical composition and, for the first time, evaluates the antimicrobial activity and cytotoxic effects of the leaf essential oil of Knema globularia (Lamk.) Warb. collected in Thanh Hoa Province, Vietnam. The essential oil was obtained by hydrodistillation and analyzed by GC–MS, leading to the identification of 47 compounds representing 97.82% of the total essential oil. The major constituents were β-(E)-caryophyllene (26.24%), α-pinene (18.44%), β-pinene (13.04%), and (3E,6E)-α-farnesene (14.36%). The essential oil showed selective antimicrobial activity against Gram-positive bacteria, with IC50 values of 64.00–80.00 µg/mL, while no significant activity was observed against Gram-negative bacteria or Candida albicans at the tested concentrations. In cytotoxic assays, the essential oil exhibited moderate effects against four human cancer cell lines (KB, HepG2, A549, and MCF-7), with IC50 values ranging from 44.82 to 61.28 µg/mL. These results suggest that the leaf essential oil of K. globularia is a promising natural source for further studies on antimicrobial and anticancer agents.

CHEMICAL PROFILING AND ANTI-INFLAMMATORY EFFECTS OF PHYSALIS ANGULATA IN LIPOPOLYSACCHARIDE-STIMULATED BONE MARROW–DERIVED DENDRITIC CELLS
type: item
description: Physalis angulata is an important medicinal plant that has been widely used in traditional medicine for the treatment of inflammation and various inflammatory-related disorders. Despite its medicinal relevance, comprehensive chemical profiling of the fruits of P. angulata collected in Vietnam has not yet been systematically investigated. In this study, a comprehensive chemical characterization of the methanolic extract of P. angulata was performed using high-resolution quadrupole time-of-flight mass spectrometry (HR-QTOF-MS), enabling rapid and accurate profiling of its bioactive constituents. Furthermore, the anti-inflammatory activity of the isolated compounds was evaluated by measuring lipopolysaccharide (LPS)-induced production of pro-inflammatory cytokines, including interleukin (IL)-12p40, IL-6, and tumor necrosis factor-α (TNF-α), in bone marrow-derived dendritic cells. Consistent with this, compound 1 exhibited potent anti-inflammatory activity against IL-12p40, IL-6, and TNF-α, with IC50 values of 1.17 ± 0.02, 7.52 ± 0.03, and 2.93 ± 0.05 µM, respectively, compared with the positive control adezmapimod (IC50 = 5.00 ± 0.01, 3.50 ± 0.01, and 7.20 ± 0.01 µM, respectively). Overall, this study provides the first comprehensive chemical profile of P. angulata from Vietnam and offers scientific evidence supporting its traditional use as a source of anti-inflammatory agents.

type: item
description: Bảy lá một hoa (Paris polyphylla var. chinensis Smith) là dược liệu có tác dụng kháng ung thư nổi bật bởi các cơ chế phân tử khác nhau. Nghiên cứu này được tiến hành nhằm đánh giá tính an toàn và tác dụng kháng u của cao định chuẩn từ thân rễ bảy lá một hoa (PPCE) trên mô hình chuột bị gây u vú bằng tế bào 4T1. Tính an toàn của PPCE được đánh giá thông qua thử nghiệm độc tính cấp đường uống. Tác dụng kháng u của PPCE được đánh giá trên chuột BALB/c gây khối u bằng cách tiêm tế bào ung thư vú 4T1 vào mô mỡ đệm tuyến vú. Chuột mang khối u được điều trị bằng PPCE ở liều uống 100, 200và 400 mg/kg/ngày hoặc doxorubicin ở liều tiêm 5 mg/kg/ngày (3 ngày một lần) trong 28 ngày liên tục. Kết quả nghiên cứu cho thấy PPCE có độc tính cấp đường uống với LD50 là 9,73 g/kg. PPCE ở liều 400 mg/kg làm giảm đáng kể thể tích khối u sau 21 và 28 ngày điều trị với phần trăm ức chế khối u trên 50% so với lô bệnh lý. PPCE ở liều 200 và 400 mg/kg làm giảm đáng kể trọng lượng khối u sau 28 ngày điều trị. Tuy nhiên, tác động của PPCE ở các liều khảo sát trên giải phẫu mô bệnh học khối u chưa rõ ràng. Các kết quả của nghiên cứu này đã cung cấp bằng chứng về tác dụng kháng u vú của PPCE trên mô hình chuột BALB/c bị gây u vú bằng tế bào 4T1, cho thấy tiềm năng hướng đến nghiên cứu ứng dụng sản phẩm hỗ trợ điều trị ung thư vú của dược liệu này.

Thành phần hóa học lá cây Maesa chisia D. Don (Primulaceae)
type: item
description: Chi Maesa (họ Anh Thảo) bao gồm khoảng 200 loài có nguồn gốc từ các vùng nhiệt đới trên thế giới, trong đó có khoảng 20 loài phân bố ở Việt Nam. Các loài thực vật thuộc chi này đã được sử dụng trong y học cổ truyền để điều trị ho, các bệnh về đường hô hấp, gãy xương và eczema. Nghiên cứu thành phần hóa học của lá loài Maesa chisia thu tại Mường Tè, Lai Châu, chúng tôi đã phân lập được 7 hợp chất bao gồm kaempferol (1), acid vanillic (2), quercetin (3), clovane-2β,9α-diol (4), vomifoliol (5), daucosterol (6) và 3-O-(6′-O-palmitoyl)-β-D-glucopyranosyl stigmasterol (7). Cấu trúc của các hợp chất phân lập được xác định bằng phân tích phổ NMR, MS và so sánh với các dữ liệu được báo cáo trong tài liệu. Đây là nghiên cứu hóa học đầu tiên về loài M. chisia ở Việt Nam. Hợp chất 3-7 lần đầu tiên được tìm thấy ở chi Maesa.

EFFECT OF SHADING LEVELS ON THE GROWTH AND DEVELOPMENT, YIELD AND QUALITY OF RHIZOME OF BLACK MUSLI (CURCULIGO ORCHIOIDES GAERTN.) PLANTED IN SUOI HAI COMMUNE, HANOI CITY
type: item
description: A two-year field experiment was conducted from January 2022 to December 2023 in Suoi Hai Commune, Hanoi City, to evaluate the effect of different shading levels on the growth and development, yield, and quality of black musli (Curculigo orchioides Gaertn.). The experiment was conducted using a completely randomized block design with four shading treatments and three replications, using a planting density of 20 x 25 cm. The results showed that shading significantly affected the ongrowth and development, yield, and quality of C. orchioides. Moderate shading at 30% and 50% resulted in markedly improved growth and survival, with plant survival rate exceeding 93% after three months compared with 79% under full sunlight. Rhizome yields were also substantially enhanced, reaching 1.177 and 1.234 tons per hectare under 50% and 30% shade, respectively, nearly double the yield of the unshaded control (0.629 tons per hectare). The highest concentrations of orcinol glucoside (0.63 – 0.67%) and curculigoside (0.16 – 0.17%) were achieved at the shading levels of 30% and 50% at harvest in November 2023. These findings demonstrate that shading plays an important role in improving both productivity and quality of C. orchioides. Shading levels between 30% and 50% are recommended for the cultivation of black musli in Suoi Hai commune, Hanoi city.
