Sennoside C（Cat No.:R037206）is a natural dianthrone glycoside found in Cassia angustifolia and Cassia acutifolia (senna), well known for their laxative properties. It consists of two anthrone units linked through a glycosidic bond, forming part of the active constituents responsible for senna’s purgative effects. In the colon, sennoside C is enzymatically converted into rhein anthrone, which stimulates intestinal motility and inhibits water reabsorption, promoting bowel evacuation. Beyond its laxative action, it shows mild antimicrobial and anti-inflammatory activities, supporting digestive health and detoxification.
