Aloin A is a naturally occurring anthraquinone C-glycoside found in the latex of Aloe vera and related species. It functions as a stimulant laxative by irritating the colonic mucosa and promoting peristalsis. The compound consists of an anthrone core substituted with a β-D-glucose moiety at the 10-position. It contributes to the bitter taste of aloe and exhibits antimicrobial activity in vitro. Regulatory bodies have restricted its use in over-the-counter laxatives due to potential genotoxicity and carcinogenicity concerns observed in animal studies. It is not considered GRAS for internal consumption.
