| 摘 要： | 以人肝癌细胞HepG2为模型研究紫甘薯花色苷的抗肿瘤活性.通过MTT实验检测紫甘薯花色苷对HepG2细胞的生长抑制作用,HE染色观察细胞形态,流式细胞仪测定细胞周期变化.MTT结果表明,不同浓度的紫甘薯花色苷处理HepG2细胞24、48、72,h后,低浓度的紫甘薯花色苷促进肿瘤细胞的生长,高浓度的紫甘薯花色苷抑制肿瘤细胞的生长,800,μg/mL花色苷处理72,h抑制率高达80%.HE染色结果表明,正常HepG2细胞的细胞核和细胞质清晰可见,而加入花色苷后,出现细胞核固缩、染色质浓集于核膜表面、形成新月形致密小斑块、细胞膜形态变得不规则等凋亡的特征.流式细胞仪分析结果表明,花色苷能够促进肿瘤细胞的凋亡,且细胞的凋亡率随花色苷浓度的增加而增大.

| Abstract: | The anti-tumor activity of purple sweet potato anthocyanin to human liver cancer HepG2 cells was studied.Cell viability,morphology characteristic and cell cycle distribution were analyzed by MTT experiment,HE dyeing and flow cytometry,respectively.The MTT results indicated that after being treated with purple sweet potato anthocyanin for 24,48,72,h,the growth of HepG2 cell was slightly promoted by low concentration of purple sweet potato anthocyanin and obviously inhibited by high concentration of purple sw... |
