Summary From the epigeal parts ofAllium turcomanicum Rgl., in addition to the known spirostans yuccagenin, neoagigenin, neoagigenone, neoagigenin, and alliogenin, we have isolated a new steriod sapogenin the structure of which has been established as neoagigenin 6-O-benzoate.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Summary 1. It has been established that the epigeal part ofTribulus terrestris L. contains five steroid saponins. Diosgenin was identified as the aglycone of all these compounds.2. The carbohydrate compositions of the saponins have been determined.For Communication I, see Izv. Akad. Nauk MSSR Ser. Khim. i Biol.

The steroid glycoside fraction ofIsostichopus badionotus, consisting of a mixture of D-xylosides of steroid alcohols, has been isolated by column chromatography on silica gel. The mixture of aglycones obtained after acid hydrolysis was separated with the aid of argentation chromatography into several fractions. GLC-MS analysis, and also the use of IR and13C NMR spectroscopy has shown that the steroid glycosides ofI. badionotus are xylosides of Δ0-, Δ7-, Δ22-, and Δ7.22-, C27-, C28-, and C29-steroids of the cholestane series. 相似文献
