Summary

Chemical Constituents from Ethyl Acetate Extract of Paederia scandens (Lour.) Merr. Collected in Vietnam

      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.

Keywords: Paederia scandens (Lour.) Merr., Rubiaceae quercetin glycoside.
