Stigmasterol
Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism. Stigmasterol is a 3beta-sterol that consists of 3beta-hydroxystigmastane having double bonds at the 5,6- and 22,23-positions. It has a role as a plant metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Stigmasterol is a natural product found in Ficus auriculata, Xylopia aromatica, and other organisms with data available. Stigmasterol is a steroid derivative characterized by the hydroxyl group in position C-3 of the steroid skeleton, and unsaturated bonds in position 5-6 of the B ring, and position 22-23 in the alkyl substituent. Stigmasterol is found in the fats and oils of soybean, calabar bean and rape seed, as well as several other vegetables, legumes, nuts, seeds, and unpasteurized milk. See also: Comfrey Root (part of); Saw Palmetto (part of); Plantago ovata seed (part of). Stigmasterol is an unsaturated plant sterol occurring in the plant fats or oils of soybean, calabar bean, and rape seed, and in a number of medicinal herbs, including the Chinese herbs Ophiopogon japonicus (Mai men dong) and American Ginseng. Stigmasterol is also found in various vegetables, legumes, nuts, seeds, and unpasteurized milk. A 3beta-sterol that consists of 3beta-hydroxystigmastane having double bonds at the 5,6- and 22,23-positions. C1907 - Drug, Natural Product > C28178 - Phytosterol > C68437 - Unsaturated Phytosterol
beta-Sitosterol
beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296). Sitosterol is a member of the class of phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3. It has a role as a sterol methyltransferase inhibitor, an anticholesteremic drug, an antioxidant, a plant metabolite and a mouse metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Active fraction of Solanum trilobatum; reduces side-effects of radiation-induced toxicity. Beta-Sitosterol is a natural product found in Elodea canadensis, Ophiopogon intermedius, and other organisms with data available. beta-Sitosterol is one of several phytosterols (plant sterols) with chemical structures similar to that of cholesterol. Sitosterols are white, waxy powders with a characteristic odor. They are hydrophobic and soluble in alcohols. beta-Sitosterol is found in many foods, some of which are ginseng, globe artichoke, sesbania flower, and common oregano.
