AIM: To investigate the chemical constituents of aerial parts of Gynura divaricata(L.)DC.METHODS: Chemical constituents were isolated with multi-chromatographic methods.Their structures were determined by spectral analysis and chemical evidence.RESULTS: 10 compounds were obtained and identified as quercetin(Ⅰ),3-O-β-Dglucopyranosyl quercetin(Ⅱ),3-O-β-D-(6→1) glucopyranosyl-αL-rhamnosyl quercetin(Ⅲ),3-O-β-D-(6→1)glucopyranosyl-α-L-rhamnosyl kaemferol(Ⅳ),epi-friedelinol(Ⅴ),epi-friedelinol acetatd(Ⅵ),β-sitosterol(Ⅶ),stigmasterol(Ⅷ),adenosine(Ⅸ) and uridine(Ⅹ).CONCLUSION: All these compounds were isolated from this plant for the first time.
