摘要 [目的]研究天胡荽的抗肿瘤活性成分。[方法]利用色谱手段进行分离纯化,应用NMR方法鉴定结构,并进行MTT法抗肿瘤试验。[结果]从天胡荽中分离鉴定了4种化合物(化合物1~4)。天胡荽的各萃取部位对LA795细胞株有一定的抑制作用,其中以正丁醇层萃取物在高浓度800 μg/ml时的抑制作用较强,而石油醚和乙酸乙酯萃取物的抑制作用相对较弱。单体化合物对LA795细胞株的抑制作用均较弱。[结论]4个化合物有一定抑制肿瘤细胞生长作用。

Abstract [Objective] To study antitumor constituents from Hydrocotyle sibthorpioides. [Method] The constituents were isolated by chromatography and identified by NMR spectroscopic methods. The antitumor experiment in vitro, the MTT was used to screen constituents of Hydrocotyle sibthorpioides. [Result] Compounds 1-4 were isolated and identified. Each extracted parts of Hydrocotyle sibthorpioides all have a certain inhibition effect on LA795, the inhibition effect of Nbutanol extract in high concentration of 800μg/ml is the strongest, while the inhibition effects of petroleum ether and ethyl acetate extracts are relative weaker. [Conclusion] The 4 compounds all have a certain inhibition effect on the growth of tumor cells.
Key words Hydrocotyle sibthorpioides; Chromatography; Antitumor
天胡荽为伞形科天胡荽属(Hydrocotyle)多年生草本植物天胡荽(Hydrocotyle sibthorpioides Lam.)的全草,生于潮湿路旁、草地、山坡、墙脚、河畔和溪边等,主要分布于江苏、安徽、浙江和江西等地;朝鲜,日本,亚洲东南部和南部等地也有分布[1-2]。天胡荽有清热利湿和退黄功用,治疗肝胆湿热之黄疸,可单用,若与茵陈、柴胡等通用,则利湿退黄效果更好。治下痢日久,湿热不清,可与刺梨根、石榴皮等水煎服,以清热利湿,涩肠止痢。湿热蕴结下焦,肾或膀胱结石,小便不利,甚或刺痛尿血者,可单用该品煎汤,或与石苇、海金砂等清热利尿药同用。其还有清肝祛风和退翳明目之功效,可治肝经风火眼痛,翳膜攀睛,可将其揉塞鼻中,或与旱莲草捣烂外敷[1-2]。现代药理研究表明,天胡荽具有抗肿瘤和抗HBsAg等作用[3]。笔者利用色谱手段对天胡荽进行分离纯化,应用NMR方法鉴定结构,并进行MTT法抗肿瘤试验,以期为天胡荽的进一步开发利用提供依据。
3 结论
天胡荽的各萃取部位对LA795细胞株有一定的抑制作用,其中以正丁醇层萃取物在高浓度800 μg/ml时的抑制作用较强,而石油醚和乙酸乙酯萃取物的抑制作用相对较弱。单体化合物对LA795细胞株的抑制作用均较弱。
