Abstract
|
|
|
|
Three compounds (1-3) were isolated from the roots of Potentilla discolor (Rosaceae). The structure of compounds 1-3 were elucidated as stigmast-5-en-3-ol (β-sitosterol, 1), 2,19α-dihydroxy-2-oxo-urs-1,12-dien-28-oic acid (fupenjic acid, 2), 3-O-β-D-glucopyranosylstigmast-5-en-3-ol (β-sitosterol β-D-glucopyranoside, 3) based on physical and spectroscopic data. 13 C-NMR assignments were completed by 2D-NMR technique. The three compounds were firstly isolated from Potentilla discolor.
