CHEMICAL CONSTITUENTS FROM THE AERIAL PARTS OF BARLERIA LUPULINA (ACANTHACEAE)

Tóm tắt

Phytochemical studies of the n-hexane and ethyl acetate fractions from aerial parts of Barleria lupulina L. (Acanthaceae) collected in Cu Chi, Ho Chi Minh city, Vietnam, led to the isolation and identification of six known compounds, including (+)-lyoniresinol (1), (+)-lyoniresinol 9ʹ-O-β-D-glucopyranoside (2), 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone 3-O-β-D-glucopyranoside (3), (3S)-l-octene-3-ol 3-O-β-D-glucopyranoside (4), uracil (5) and stigmasterol (6). The structures of the isolated compounds were determined on the basis of detailed spectroscopic (MS and NMR) analysis and comparison with reported literature. Compounds 1, 3, 4, and 5 were found for the first time from the Barleria genus.
