摘要: 选用植物活性物质单体白藜芦醇和绿原酸作用于中国仓鼠卵巢(CHO)细胞,采用MTS法、WST-1法、CCK-8法、XTT法和MTT法测定细胞存活率,并将MTS法、WST-1法、CCK-8法、XTT法这4种方法与传统的MTT法进行比较分析,从中选出最佳的检测方法;通过IC50值比较白藜芦醇和绿原酸毒性大小。结果显示:CCK-8法所得结果稳定,且与MTT法所测得的IC50值最接近,为最佳选择;WST-1法的实验可重复性较差,结果偏小;XTT法是4种方法中最不稳定的,作用时间、检测波长最难确定,且实验重复性差。CCK-8法、MTS法、WST-1法、XTT法和MTT法测定所得白藜芦醇的IC50值分别是116.86、124.68、64.90、162.86、86.30μmol/L;绿原酸的IC50值分别为2808.60、1119.96、1029.72、1325.43、2852.63μmol/L,同种方法下绿原酸的IC50值均高于白藜芦醇的IC50值。结论是测定植物活性成分对细胞存活率影响的方法以CCK-8为最好。白藜芦醇对CHO细胞的毒性比绿原酸大。

Abstract: Resveratrol and chlorogenic acid, as phytochemicals were used to treat CHO cells. Cell viability was measured by using MTS, WST-1, CCK-8, XTT and MTT methods and the optimal method from MTS, WST-1, CCK-8 and XTT was screened by comparing with the conventional MTT methods. The cytotoxicity of resveratrol and cholorogenic was compared by IC50 value. Results: Compared with MTT assay, CCK-8 assay was timesaving, repeatable and easily operated. IC50 of resveratrol and chlorogenic acid detected by CCK-8 were closed to one by MTT assay. Thus, CCK-8 assay was optimal. On the contrary, WST-1 assay was less repeatable and cell viability rate tended to smaller. XTT assay was the worst because of its instability in wavelength, experimental time and repetition. IC50 of resveratrol on CHO cells were 116.86、124.68、64.90、329.83、86.30 μmol/L in CCK-8、MTS、WST-1、XTT and MTT assay. While IC50 of chlorogenic acid on cells were 2808.60、1119.96、1029.72、1325.43、2852.63 μmol/L respectively. The results showed higher IC50 value for chlorogenic acid. Conclusions: CCK-8 assay was a optimal method for cell viability ; Resveratrol showed higher cytotoxicity to CHO cells compared with chlorogenic acid.
