Isolithocholic Acid (β-Lithocholic acid) 是石胆酸的一种同分异构体。Isolithocholic Acid 是一种胆酸，由 Lithocholic acid 或 Lithocholic acid 3α-sulfate 经微生物代谢形成。

Isolithocholic Acid (β-Lithocholic acid) is an isomer of Lithocholic acid. Isolithocholic Acid, a bile acid, is formed by microbial metabolism of Lithocholic acid or Lithocholic acid 3α-sulfate.

Isolithocholic Acid at 0.01 % does not inhibit spore germination and outgrowth of CF5 and M120, but it significantly inhibits at the higher concentration (0.1 %). Isolithocholic Acid (0.00003 %) prevents growth of CD196, M68, CF5, 630, and BI9 and significant decreases strains CF5, BI9, M120, and 630 in toxin activity. Isolithocholic Acid (0.0003 %) makes that all strains displays a significant decrease in toxin activity, except for R20291 and M120[3].

The levels of fecal Isolithocholic Acid shows obvious decreases from day 28 onward in the high fat diet (HFD) group compared with rats fed a normal diet[4].
