Astragalus Membranaceus
''Astragalus propinquus'' (syn. ''Astragalus membranaceus'', commonly known as Mongolian milkvetch in English; 'Хунчир' in Mongolian; ''huáng qí'' (), ''běi qí'' () or ''huáng huā huáng qí'' (), in Mongolia, is a flowering plant in the family Fabaceae. It is one of the 50 fundamental herbs used in traditional Mongolian medicine. It is a perennial plant and it is not listed as being threatened. Herbalism ''A. propinquus'' is used in traditional Chinese medicine (TCM). ''A. propinquus'' is a component in Lectranal, a food supplement used in treatment of seasonal allergic rhinitis, though there is limited evidence of its effectiveness. Chemistry Chemical constituents of the roots (Radix Astragali) include polysaccharides and triterpenoids (such as astragalosides), as well as isoflavones (including kumatakenin, calycosin, and formononetin) and their glycosides and malonates. An extract of ''A. propinquus'' called TA-65 may activate telomerase, extending th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triterpene Glycosides
Triterpenes are a class of chemical compounds composed of three terpene units with the molecular formula C30H48; they may also be thought of as consisting of six isoprene units. Animals, plants and fungi all produce triterpenes, including squalene, the precursor to all steroids. Structures Triterpenes exist in a great variety of structures. Nearly 200 different skeletons have been identified. These skeletons may be broadly divided according to the number of rings present. In general pentacyclic structures (5 rings) tend to dominate. Squalene is biosynthesized through the head-to-head condensation of two farnesyl pyrophosphate units. This coupling converts a pair of C15 components into a C30 product. Squalene serves as precursor for the formation of many triterpenoids, including bacterial hopanoids and eukaryotic sterols. Triterpenoids By definition triterpenoids are triterpenes that possess heteroatoms, usually oxygen. The terms ''triterpene'' and ''triterpenoid'' o ...
