ISSN: 0258-6967. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Chem. constituents of Asparagus tenuifolius Lam. were investigated. Three saponins were obtained as crystals. Physicochem.Several reagents with their cas registry numbers 509-99-9 and 60267-24-5 are used here. anal. showed that saponin C and D were identical with the Asparagosides C and D isolated from A. officinalis L. Saponin E exhibited a m.p. of 22-227°C. IR and MS anal. following acidic hydrolysis showed it to be a sarsasapogenin and its three sugar mols. were D-glucose, D-xylose, and L-rhamnose. GC allowed the isolation of sarsasapogenin, yamogenin, pennogenin, neohecogenin, 25-b-spirostan-3,5-diene of yamogenin and 3-formylsarsasapogenin from the saponin mixt. after hydrolysis. These sapogenins were identified by means of chromatog. techniques, IR, NMR and mass spectrometry and were shown to be identical with ref. samples. .
