摘 要:目的对毛排钱草地上部分的化学成分及其抗肿瘤活性进行研究。方法对干燥的毛排钱草地上部分以甲醇于50℃下萃取浓缩,以水溶解滤过得水溶及水不溶性两部分,水可溶部分用正丁醇提取化合物。通过波谱解析、对照品比较及与文献报道对比鉴定其化学结构。并对得到的化合物进行了细胞毒活性研究。结果正丁醇提取物分离纯化后得到8个化合物。经鉴定为N,N二甲基色胺(Ⅰ)、5-甲氧基-N,N-二甲基色胺(Ⅱ)、柠檬酚(Ⅲ)、异柠檬酚(Ⅳ)、(Z)-1-(4-羟基-2,3-二甲氧苯基)-3-(4-羟基苯)丙烯(Ⅴ)、(Z)-1-(3-羟基-2,4-二甲氧苯基)-3-(4-羟基-3-甲氧基苯基)丙烯(Ⅵ)、原儿茶酸甲酯(Ⅶ)、香橙素[(2R,3R)-2,3-二氢-3,5,7-三羟基-2-(4-羟基苯基)-4H-1-苯并毗喃-4-酮,Ⅷ]。结论8个化合物均为首次从该植物中分得,在MTT抗肿瘤实验中,化合物Ⅰ、Ⅲ~Ⅵ均具有一定的细胞毒活性。Objective To investigate the chemical constituents in Desrnodium blandurn and their antitumor bioactivity. Methods Various chromatographic techniques were employed for the isolation and purification of the constituents by butanol at 50 ℃ including silica gel, Sephadex LH-20. The compounds structures were elucidated by spectral analyses (IR, UV, NMR, and MS). Then their cytotoxic activity was studied. Results They were identified as N, N-dimethyltryptamine ( Ⅰ ), 5-methoxy-N, N-dimethyl- tryptamine ( Ⅱ ), citrusinol ( Ⅲ ), yukovanol ( Ⅳ ), (Z)-l-(4-hydroxy-2, 3-dimethoxyphenyl) 3 (4- hydroxyphenyl) propene ( Ⅴ ), ( Z)-1- (3-hydroxy-2, 4-dimethoxy phenyl)-3- (4-hydroxy-3-methoxy-phenyl) propene ( Ⅵ ), methyl protocatechuate (Ⅶ), katuranin (Ⅷ). Conclusion Eight compounds are isolated from the stems of D. blandum for the first time. In the MTT antitumor experiments, compounds Ⅰ andⅢ--Ⅵ have the cytotoxic activity to KB cell.
