摘要

目的: 对乌骨藤中白桦酯酸进行提取分离

并探讨其抗肿瘤活性。方法: 采用硅胶柱色谱法、Sephadex LH-20凝胶柱色谱法及半制备高效液相色谱法

对白桦酯酸进行提取分离

并采用结晶紫法

以细胞死亡率为检测指标

观察白桦酯酸在不同质量浓度1~500 mg·L-1情况下

对细胞密度为1×104/孔的4种肿瘤细胞分别作用12

48 h的生长抑制作用。结果: 白桦酯酸对人宫颈癌细胞HeLa、人胃癌细胞MGC、人乳腺癌细胞MCF-7具有很好的增殖抑制作用

并呈剂量依赖效应

在质量浓度为500 mg·L-1作用48 h时

对Hela细胞及MGC细胞的死亡率分别为77.9%

81.7%

质量浓度为100 mg·L-1作用48 h时

对MCF-7的细胞死亡率为74.1%

但对人乳腺导管癌细胞(ZR株)作用不显著。结论: 白桦酯酸对HeLa

MGC

MCF-7肿瘤细胞具有抗肿瘤活性

对ZR株肿瘤细胞作用不明显。

Abstract

Objective: Extraction and isolation of betulinic acid from Marsdenia tenacissima and investigate the anti-tumor activity were investigated. Method : By using silica gel column chromatography

Sephadex LH-20 chromatography and semi-preparative reversed phase liquid chromatograph

extraction and isolation of betulinic acid

and MTT assay was applied in demonstrating effect on antitumor effect in four tumor cells with different concentrations and at different action time. Result: The growth of cervical cancer cells HeLa

gastric cancer cells MGC

breast cancer MCF-7 was significantly inhibited by betulinic acid with a manner of dose-dependence. After 48 h

the cell death rate of HeLa and MGC was 77.9%

81.7%

respectively. When the concentration of the sample was 500 mg·L-1

the cell death rate of MCF-7 was 74.1%

when the concentration of the sample was 100 mg·L-1

the effect on ducal carcinoma cells was not significant. Conclusion: Betulinic acid has an anti-tumor activity on HeLa

MGC

MCF-7.
