Intestinal Microflora Diversity of Rats Treated with Scutellariae Radix Based on Theory of “Insight into Abdomen” / 中国实验方剂学杂志

ABSTRACT

Objective: To explore the effect of Scutellariae Radix on the diversity of intestinal flora in rats under physiological conditions, in order to determine the property of Scutellariae Radix property. Method: 16S rRNA high-throughput gene sequencing technique was used to detect the cecum solutes of rats treated with Scutellariae Radix (10 g·kg-1). The number, richness and diversity index of the intestinal flora taxon (OTUs) and the differential phylum and genus were comprehensively analyzed. The network visualization was used to find the correlation between differential phylum and genus. Result: Based on the Illumina Miseq platform, compared with the blank group, the number of OTUs and the index of richness and diversity of the intestinal flora of the rats treated with Scutellariae Radix decreased. Bacteroidetes and Spirochaetes were significantly up-regulated(PPPPPRuminococcus, Paraprevotella, Prevotella and Oscillospira. Conclusion: Scutellariae Radix can reduce the diversity of intestinal flora and inhibit the metabolism of the body, so its property is cold.
