CHEMICAL CONSTITUENTS OF NOTOSERIS RHOMBIFORMIS

AIMTo investigate the chemical constituents from the whole plant of the endemic plant Notoseris rhombiformis Shih. METHODSColumn chromatography was used for separation and purification, while spectral analysis was used for structure elucidation. RESULTSEight compounds were isolated from the whole plant of this Chinese endemic plant and their structures were elucidated as notoserolide A (1), notoserolide D (2), austricin (3), jacquilenin (4), 3β,14-dihydroxy-11β,13-dihydrocostunolide (5), P-hydroxyphenylacetic acid (6), luteolin-7-O-β-D-glucopyranoside (7) and daucosterol (8), respectively. CONCLUSIONAll compounds were isolated from this plant for the first time. Among them, 2 is a new compound.
