Prostaglandin-Mediated Action of Sennosides

Pharmacology, 2008
The aim of this study was to investigate whether prostaglandins (PG) are involved in the mediation of sennoside-induced colonic fluid and electrolyte secretion. Oral administration of senna pod extract dose-dependently reversed net absorption of water, sodium and chloride to net secretion, increased potassium secretion and stimulated the release of PGE&

New Aspects on the Metabolism of the Sennosides

Pharmacology, 2008
Pure sennoside B was administered to rats. On appearance of the first wet faeces, sennoside B and its metabolites were determined in different parts of the alimentary tract, in faeces and in the urine. The total recovery of unchanged sennoside B and its metabolites was determined by alkali fusion followed by colorimetry and high-pressure liquid ...
