Tóm tắt

      Phytochemical study on the ethyl acetate extract of the rhizomes of Paederia scandens (Lour.) Merr. resulted in the isolation of nine compounds: anthraquinone (1), 3,3′-dimethoxyellagic acid 4′-O-α-L-rhamnopyranoside (2), 3′,4′,7-trihydroxyflavanone (3), betulinic acid (4), kaempferol (5), linarin (6), paederoside (7), quercetin 3-O-α-L-rhamnosyl-(1→6)-β-D-glucopyranosyl-(1→3)-β-D-glucopyranoside (8), and kaempferol 3-O-β-D-glucopyranoside (9) on the basis of experimental spectral data. Compounds 1, 2, 3, 6, and 8 were reported from P. scandens for the first time.
