目的:考察白术、茯苓多糖在胃肠道环境中的代谢情况。方法:白术、茯苓多糖分别与人工胃液、肠液和肠道菌共孵育,采用3,5-二硝基水杨酸法(DNS法)测定多糖的含量变化,考察白术、茯苓多糖在人工胃肠道环境中的代谢以及与肠道菌共孵育的变化。结果:白术、茯苓多糖在人工胃肠道环境中没有明显代谢,而与肠道菌的共孵育过程中则产生显著代谢。结论:白术、茯苓多糖在胃肠道中的代谢主要是在肠道中进行,肠道菌在此过程中发挥着重要作用。
Objective: To investigate the metabolism of Atractylodes macrocephala and Poria cocos polysaccharide in gastrointestinal environment. Methods: Atractylodes macrocephala and tuckahoe polysaccharide were respectively incubated with artificial gastric juice, intestinal juice and intestinal bacteria. The contents of polysaccharides were determined by 3,5-dinitrosalicylic acid method (DNS method) Metabolism in the environment of the environment and co-incubation with gut bacteria. Results: Atractylodes macrocephalae and tuckahoe polysaccharides did not show obvious metabolism in the artificial gastrointestinal environment, but produced significant metabolism during the process of co-incubation with intestinal bacteria. Conclusion: Atractylodes macrocephalae and tuckahoe polysaccharides are mainly metabolized in the intestine and enterobacteria play an important role in the process.
