[Determination of sennoside A and sennoside B simultaneously in health food by HPLC].
Wei sheng yan jiu = Journal of hygiene research, 2013To develop an analytical method for determination of sennoside A and sennoside B simultaneously in health food by high performance liquid chromatography (HPLC).Samples were extracted by ultrasound extraction and determined by HPLC with a UV detector. Using a Synergi Hydro-RP (250 mm x 4.6 mm, 4 microm) column and a mixture of CH3CN: 1.0% CH3COOH (17:83)

[Determination of sennosides and degraded products in the process of sennoside metabolism by HPLC].
Se pu = Chinese journal of chromatography, 2005A method for the separation and determination of sennosides A and B and the main composition (sennidins A and B) in degraded products of sennosides by linear gradient high performance liquid chromatography has been developed. Separation conditions were as follows: column, a Spherisorb C18 column (250 mm x 4.6 mm i.d., 10 microm); column temperature, 40

[The mechanism of action of sennosides].
Annales de gastroenterologie et d'hepatologie, 1996A review of the recent progress in the study of the mode of action of the sennosides, the active constituents of the senna drug, is presented. An interaction between rhein anthrone, the active metabolite of the sennosides, and the immune cells of the colon is suggested as a base for laxative activity.

An HPLC method to determine sennoside A and sennoside B in Sennae fructus and Sennae folium.
Pharmeuropa bio & scientific notes, 2015The current Ph. Eur. monographs for senna pods, senna leaf and senna leaf dry extract standardised describe a photometric assay based on the Bornträger reaction to determine hydroxyanthracene glycosides, calculated as sennoside B. The method is timeconsuming, unspecific for sennosides and the precision is not adequate for a modern assay.The photometric
