Effects of LF on gut microbial diversity in depressed rats. (a) Indices of chao 1. (b) Indices of ace. (c) Indices of shannon. (d) Beta diversity of PCoA. There was a noticeable difference in the composition of the flora structure between the K and M groups. Additionally, it was observed that the structure of intestinal flora in the L group rats closely resembled that of K group. Note: *p < 0.05, **p < 0.01. K control group; M model group; L LF treatment group.
