ABSTRACT

Objective: To investigate the chemical constituents from the stems of Gnaphlium affine. Methods: The constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative TLC. The structures were identified on the basis of spectral data and physiochemical characteristics. Results: Fifteen compounds were isolated from 70% ethanol extracts of G. affine and identified as 3-methoxyphenol1-O-α-L-rhamnopyranosyl-(1→6)-O-β- D-glucopyranoside (1), 3', 5-dihydroxy-2-(4- hydroxybenzyl)-3-methoxybibenzyl (2), physcion (3), aldehyde (4), luteolin-4'-O-β-D-glucoside (5), faradiol 3-O-palmitate (6), betulinic acid (7), anabellamide (8), 4-O-D-glucopyranosyl-p-coumaric acid methyl ester (9), valene-1 (10)-ene-8, 11-diol (10), longumoside A (11), grossamiade K (12), quercetin-3-O-rutin-7-O-glucoside (13), luteolin-7-O-β-D-glucopyranosyl-(1→6)-[(6'''- O-caffeoylquinic)-β-D-glucopyranoside] (14), and isoverbascoside (15). Conclusion: Compounds 2 and 11 are reported from the plants in Gnaphalium L. for the first time. Compounds 2, 3, 6, 8, 13, and 14 are isolated from this plant material for the first time.
