Senna leaves: Origin of senna:
The dried leaflets of Cassia acutifolia, known as Alexandrian Senna, and of Cassia angustifolia, known as Indian Senna F. Leguminosae.
1-The main active constituents in senna are sennosides (A-B-C-D) which are dimeric glycosides and other constituents as palmitic acid , barbalonic acid .
2-Anthraquinone glycosides the sennoside A and B hydrolyze to give aglycones .
3-senna also has 6-hydroxymusicin glycosides, naphthalene glycosides, and tinnevellin glycosides.
Uses of senna : 1-Senna is a powerful laxative, it is effective specially in older patients .
2- Senna has some activity against cancer, too .
3-In skin, senna is very useful for the skin . Our skin is damaged by environmental…show more content… Leaves and stems have the highest moisture content (76.36 and 77.46 g/100 g, resp.), while inflorescence has the lowest content (71.31 g/100 g). Carbohydrates are the most abundant materials in all the parts of fennel and range from 18.44 to 22.82 g/100 g. Fats are the less abundant materials; proteins range between 1.08 g/100 g in stems and 1.37 g/100 g in the inflorescences.
The inflorescences and stem contain the highest amount of fat (1.28 g/100 g) and reduce the amount of sugar (1.49 g/100 g), inflorescences have the highest value of energy while leaves and stems gave the lowest value of energy.
Unsaturated fatty acids have higher concentration than saturated fatty acid, which (UFA) range from 66% to 80% in fennel. The lowest concentration of n-3 fatty acids was found in inflorescences, while the highest concentration was found in fennel leaves.
Mechanism of action:
Laxatives are weaker than cathartics and purgative in action and used for emptying of the rectum and elimination of forming stools.
Cathartics are very strong in action and used for emptying of the colon and elimination of the liquid form of
