Chemical Constituents from Ethyl Acetate Extract of Polygonum perfoliatum L. Collected in Vietnam
Phytochemical study of an ethyl acetate extract of Polygonum perfoliatum L. rhizome resulted in the isolation of eight compounds (1 – 8). They were identified as physcion (1), trans-4-hydroxymellein (2), ellagic acid 3,3′,4-trimethoxy 4′-O-a-L-rhamnopyranoside (3), myricetin (4), myricetin-3-rhamnose (5), epicatechin (6), quercetin 3-O-β-D- glucopyranoside (7) N-[(4R)-2,5-dioxo-4- imidazolidinyl]-carbamic acid (8) on the basis of spectral data. Among them, compounds 2, 3, 4, 5 were isolated from this plant for the first time, and compound 8 was obtained from this genus for the first time.
Keywords: Polygonum perfoliatum, Polygonum genus, N-[(4R)-2,5-dioxo-4- imidazolidinyl]-carbamic acid.
