  • In this study, we investigated the anti-inflammatory effects of fupenjic acid (FA) isolated from the Potentilla discolor in both RAW 264.7 and mouse primary peritoneal macrophage cells. FA pretreatment significantly inhibited nitric oxide (NO) and prostaglandin $E_2(PGE_2)$ productions in the lipopolysaccharide (LPS)-induced RAW 264.7 and mouse primary peritoneal macrophage cells. Consistent with these observations, Western blot and RT-PCR analyses revealed that FA inhibited the LPS-induced expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein and mRNA levels. In addition, FA reduced the release of tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-6 (IL-6). These results suggest that the down regulation of iNOS and COX-2 expression and TNF-$\alpha$ and IL-6 production by fupenjic acid are responsible for its anti-inflammatory effects.

  • 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 $({\beta}-sitosterol,\;1),\;2,19{\alpha}-dihydroxy$-2-oxo-urs-1,12-dien-28-oic acid (fupenjic acid, 2), 3-O-${\beta}$-D-glucopyranosylstigmast-5-en-3-ol (${\beta}-sitosterol\;{\beta}-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.
