OBJECTIVE
To study the chemical constituents from aerial parts of Fallopia dumetosum.
METHODS
The 80% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography. The compounds isolated from the plant were identified by physicochemical properties and spectroscopic evidence.
RESULTS
Ten compounds were obtained and identified as emodin (1), physcion (2), quercetin (3), luteolin (4), 5"- methoxy-hydnocarpin (5), ethylparaben (6), protocatechuic acid (7), (2S,3S, 4R) -sphinganine-(2'R) -delta5'6' (E) -2'-hydroxyl tetracosanoylamino (8), beta-sitosterol (9), and daucosterol (10).
CONCLUSIONS
Anthraquinones and flavones were the major constituents of this plant. All compounds were isolated firstly from this plant, and compounds 5, 7, and 8 were isolated from the genus Fallopia for the first time.
