摘要: 本实验旨在研究茶籽皂苷对高脂血症大鼠肠道菌群的影响。60只雄性Wistar大鼠适应性喂养1周后随机分为正常组(10只,C组)和造模组(50只)。C组饲喂基础饲料,造模组饲喂高脂饲料。造模成功后,将造模组大鼠按体重随机分为模型对照组(H组)、阳性对照组(P组)、茶籽皂苷高、中、低剂量组(TSH组、TSM组、TSL组),并进行灌胃。灌胃4周后,用16S rRNA测序技术检测茶籽皂苷对肠道菌群的影响。结果显示:与C组相比,H组大鼠肠道菌群的丰度和多样性显著降低,其群落结构从门到属均发生显著变化。灌胃茶籽皂苷后,肠道菌群的丰度以及从门到属的群落结构也均得到有效调节,有益菌群相对丰度提升,致病菌群得到抑制。结果表明茶籽皂苷对由高脂饲料诱发的高脂血症大鼠的肠道菌群起到正向调节作用。

Abstract: This study was designed to elucidate the effect of the tea seed saponin on intestinal microflora of hyperlipidemic rats.After a week adaptive feeding,60 male Wistar rats were randomly divided into normal group (10 rats,group C) and model group (50 rats),which were fed with basic diet and high fat diet.After successful modeling,the model rats were randomly divided into group H,group P,group TSL,group TSM,and group TSH according to their body weight,and were intragastrically administered.Rat intestinal microflora was detected using 16S rRNA sequencing technology after 4 weeks of intervention.The results showed that the richness and diversity of intestinal microflora in group H were significantly decreased,and the community structure changed significantly from gate to genus compared with group C.After the application of tea seed saponin,the abundance of intestinal microflora and the community structure from the door to the genus were also effectively regulated,the relative abundance of beneficial bacteria increased,and the pathogenic bacteria were inhibited.The results indicated that tea seed saponin plays a positive role in regulating the intestinal microflora of hyperlipidemic rats induced by high fat diet.
