Abstract:
OBJECTIVETo study the chemical constituents from the antioxidant fraction of Neo-Taraxacum siphonathum.
METHODVarious chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated on the basis of chemical evidence and spectral analysis.
RESULTTen compounds were isolated and identified from Neo-T. siphonathum, caffeic acid (1), chlorogenic acid (2), quercetin (3), luteolin (4), quercetin-3-O-beta-D-glucopyranoside (5), quercetin-3-O-alpha-D-arabinofuranoside (6), quercetin-3-O-alpha-D-arabinopyranoside (7), luteolin-7-O-beta-D-glucopyranoside (8), beta-sitosterol (9) and daucosterol (10).
CONCLUSIONCompounds 1-10 were isolated from this plant for the first time.
