Study of the Mechanism Underlying the Antihypertensive Effects of Eucommia ulmoides and Tribulus terrestris Based on an Analysis of the Intestinal Microbiota and Metabonomics

Figure 6

Correlation of intestinal microbiota and metabonomics. The vertical direction represents the differential bacteria at the level of 16S OTUs (species, genus), and the horizontal direction represents the names of differential metabolite. The value range of the correlation coefficient is (-1, +1). The intestinal microbiota and fecal metabolites show and , which is considered to demonstrate a high correlation and a significant effect. The red oval indicates a positive correlation, and the blue oval indicates a negative correlation between the intestinal microbiota and fecal metabolites.
