Abstract:
Objective To explore the characteristics of the interactions between traditional laxative medicine Cannabis Fructus and human gut microflora. Methods HPLC method was used to determine the content of the main unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction. At the same time, solid culture and liquid culture in vitro anaerobic culture method were combined with 16 S rRNA technology to analyze the interactions between Cannabis Fructus Decotion and human gut microflora. Moreover, the metabolits of linoleic acid and linolenic acid in Cannabis Fructus Decoction by human intestinal microflora were determined using HPLC method. At the same time, the possible conjugated linolenic acid and linoleic acid were determined. Results Cannabis Fructus Decoction promoted the growth of Proteobacteria significantly, which showed that Escherichia-shigella was significantly increased (P < 0.01), but the growth of Bacteroidetes was decreased (P < 0.01), and the content of unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction were reduced after being incubated with human intestinal bacteria, and the metabolites were conjugated linoleic acid and conjugated linolenic acid. Conclusion The interactions between Cannabis Fructus Decoction and human intestinal microflora are obvious. The Chinese medicine can change the structure of the gut microflora, and the gut microflora can metabolize the drug components. This analysis method partially restores the pharmacokinetics process of the oral administration drug in the human intestinal tract. It could provide a new insight of the mechanism research of Cannabis Fructus.
