OBJECTIVE To study the constituents from Sarcandra glabra(Thunb) Nakai. METHODS The compouds were isolated by column chromatography and identified by spectroscopic methods, respectively. RESULTS Eleven compouds were isolated and identified as shizukanolide(Ⅰ) , furanodienone (Ⅱ) , lupeol (Ⅲ) , 24-hydroxylupeol (Ⅳ) , pinostrobin (Ⅴ) , 2', 6'-dihydroxy-4'-methoxydihydrochalcone (Ⅵ), 7-rnethylnaringenin(Ⅶ) , eleutheroside B1 (Ⅷ), 3,4-dihydroxybenzonic acid(Ⅸ), palmitic acid(Ⅹ) and β-sitosterol(Ⅺ), respectively. CONCLUSION Compoud Ⅰ -Ⅳ and Ⅶ - Ⅺ are isolated from Sarcandra glabra for the first time.
