Two new steroid glycosides of the furostanol series have been isolated fromAllium narcissiflorum Wills., and their structures have been shown.     

Steroid saponins and sapogenins of Allium X. Neoagigenin 6-O-benzoate from Allium turcomanicum

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.

Steroid saponins II. Glycosides of Tribulus terrestris

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.

Steroid saponins and sapogenins of Allium IV. Karatavigenin — A new sapogenin from Allium karataviense

Summary For all the bisbenzyltetrahydroisoquinoline alkaloids considered except thalisopine, positive CEs are found in the case of the SS configuration and negative CEs in the case of the RS configuration.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Glycosides of marine invertebrates. VIII. Steroid glycosides of the holothurianIsostichopus badionotus

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 Δ^7.22-, C₂₇-, C₂₈-, and C₂₉-steroids of the cholestane series.
