Abstract Heat-processed Gynostemma pentaphyllum has shown strong activity against human lung carcinoma A549 cells. In this study, two dammarane-type saponins together with two known compounds were isolated from the ethanol extract of the heat-processed leaves of G. pentaphyllum. They were identified as 2α,3β,12β-trihydroxydammar-20(22),24-diene-3-O-β-D-glucopyranoside (1, namely damulin E), 2α,3β,
抽象的 热处理后的绞股蓝对人肺癌A549细胞表现出很强的活性。在本研究中,从热加工的G. pentaphyllum叶的乙醇提取物中分离出两种达玛烷型皂苷以及两种已知化合物。经鉴定为2α , 3β ,12β-三羟基达玛-20(22),24-二烯-3- O - β -D-吡喃葡萄糖苷( 1 ,即达木林E), 2α , 3β , 12β-使用NMR和质谱分别鉴定三羟基达玛-20,24-二烯-3- O - β -D-吡喃葡萄糖苷( 2 ,即达木林F)、达木林A( 3 )和达木林B( 4 )。使用 CCK-8 测定,Damulin E 和 damulin F 在体外对 A549、H1299、T24、SH-SY5Y 和 K562 细胞系表现出中等活性。
