摘要:

以天然蝉花虫草生药为对照,以中国仓鼠卵巢肿瘤(Chinese hamster ovary,CHO)细胞株为模型,采用刃天青染色法检测人工培育蝉花虫草的抗肿瘤活性。结果表明:人工培育蝉花虫草和天然蝉花虫草生药都具有抗肿瘤活性,且活性成分均为中等极性化合物。对人工培育蝉花虫草中的抗肿瘤活性成分进行分离制备,得到两种化合物,命名为化合物1和化合物2。化合物1经鉴定为虫草素,化合物2经纯度验证为纯品,活性验证结果发现当其质量浓度为50 μg/mL时,对CHO细胞抑制率高达(94.55±2.33)%。

Abstract:

The antitumor activity of the cultured fruiting bodies of Cordyceps cicadae on Chinese hamster ovary (CHO) cells
was investigated by measuring cell viability using a resazurin reduction assay in comparison with that of wild Cordyceps
cicadae. The experimental results showed that both samples had antitumor activity and contained mid-polar compounds.
Two bioactive compounds, namely components 1 and 2, were separated from the cultured fruiting bodies of Cordyceps
cicadae. Component 1 was identified as cordycepin. Component 2 (50 μg/mL) was identified as a purified compound that
could inhibit the viability of CHO cells by up to (94.55±2.33)%.

Key words: cultivated Cordyceps cicadae, antitumor activity, Chinese hamster ovary (CHO) cells, cordycepin
