Two aloe-emodin dianthrone diglucosides (I and II) were isolated from the leaves of Cassia angustifolia Vahl by successive column chromatography with Amberlite XAD-2, silica gel, Polyamide C-200 and Sephadex LH-20. The stereostructures of I and II were elucidated as trans and meso isomers at 10-10',
Genotoxicity tests were performed by several laboratories with the drug fructus sennae, senna extract, sennosides, rhein and aloe-emodin. The drug fructus sennae, the sennosides and rhein did not increase mutation frequencies in the following test systems: bacterial systems (Salmonella reverse
Therapeutic doses of two laxatives (Agiolax and Sennatin) were repeatedly administered to 10 healthy volunteers in a two-way change-over design. Blood samples were collected up to 96 h after the first dose, and plasma levels of total aloe-emodin and rhein were determined simultaneously with a
This study aimed to explore the mechanism involved in the synergistic purgative action of aloe-emodin anthrone and rhein anthrone, the active metabolites of sennoside C. Aloe-emodin anthrone and rhein anthrone, and their equimolar mixture, induced excretion of an approximately equal number of faeces
Orally administered barbaloin (100 mg/kg) did not induce any diarrhea in male Wistar rats, in spite of severe diarrhea with sennoside B (40 mg/kg). Also, in gnotobiote rats mono-associated with Peptostreptococcus intermedius, a human intestinal anaerobe capable of reducing sennidins to rhein
