摘要: 首次用斑马鱼模型探索何首乌中18种成分的肝脏毒性作用,为何首乌的肝毒性物质基础研究提供依据。对肝脏荧光转基因斑马鱼给以高、中、低剂量的18种何首乌主要成分72 h,并分别于给药后24、48、72 h用荧光显微镜对其进行拍照。拍好的图片通过Image J软件进行肝脏面积和荧光强度分析。大黄素组、大黄酸组、芦荟大黄素组、大黄素-1-O-葡萄糖苷组、大黄素甲醚-8-O-葡萄糖苷组、芦荟大黄素-8-O-葡萄糖苷组及阳性对照组(对乙酰氨基酚)的肝脏面积和肝脏荧光强度与空白组相比显著降低;而大黄酚组、大黄素甲醚组、大黄素-8-O-葡萄糖苷组、大黄酸-8-O-葡萄糖苷组、大黄酚-1-O-葡萄糖苷组、大黄酚-8-O-葡萄糖苷组、芦荟大黄素-3-羟甲基葡萄糖苷组、白藜芦醇组、没食子酸组、儿茶素组、表儿茶素组的肝脏面积和肝脏荧光强度与空白组相比无显著差异;此外,二苯乙烯苷组的肝脏荧光强度与空白组相比显著增高。由此可见大黄素、大黄酸、芦荟大黄素、大黄素-1-O-葡萄糖苷、大黄素甲醚-8-O-葡萄糖苷、芦荟大黄素-8-O-葡萄糖苷对斑马鱼幼鱼肝脏具有一定毒性作用。何首乌的肝毒性作用可能还是由蒽醌类化合物介导,其物质基础与上述6种蒽醌成分有关,并以结合蒽醌为主。

Abstract: Explored the hepatotoxicity effect of eighteen constituents from polygoni multiflori radix with zebrafish model for the first time to provide reference for the hepatotoxicity material basis study of polygoni multiflori radix.The liver fluorescence transgenic zebrafish were given the 18 components of polygoni multiflori radix at high,medium and low doses,respectively for 72 h and these zebrafish were photographed by fluorescence microscope at 24 h,48 h and 72 h after the administration,respectively.These pictures were analyzed by Image J software for the liver area and fluorescence intensity. Compared with the control group,the liver area and liver fluorescence intensity of emodin group,rhein group,aloe emodin group,emodin-1-O-glucoside group,physcion-8-O-glucoside group,aloe emodin-8-O-glucoside group and positive control group (acetaminophen) decreased significantly,but those of chrysophanol group,physcion group,emodin-8-O-glucoside group,rhein-8-O-glucoside group,chrysophanol-1-O-glucoside group,chrysophano l-8-O-glucoside group,aloe emodin-3-hydroxy methyl glucoside group,resveratrol group,gallic acid group,catechin group,epicatechin group had no significant difference,except the tetrahydroxystilbene glucoside group,which was significantly higher. Thus it could be seen that emodin,rhein,aloe emodin,emodin-1-O-glucoside,physcion-8-O-glucoside,aloe emodin-8-O-glucoside had certain toxic effects on zebrafish larvae liver.The hepatotoxicity of polygoni multiflori radix may be mediated by anthraquinone compounds and its material basis is related to the 6 anthraquinone compounds mentioned above,which were mainly on the combined anthraquinones.

Key words: zebrafish, polygoni multiflori radix, hepatotoxicity, anthraquinone
