A spirostanol glycoside was isolated, together with some known compounds, from the methanolic extract of the fruits of Asparagus officinalis and characterized by chemical and spectral methods including 13C NMR-DEPT and 2D-hetcor NMR spectra.The spirostanol glycoside caused 100percent immobilization of human spermatozoa at 1.5percent level.Key Word Index - Asparagus officinalis; Liliaceae; spirostanol glycoside; 13C NMR-DEPT mode; 2D-heteronuclear shift correlation NMR spectrum; spermicidal potential.
STEROID GLYCOSIDES OF THE SEEDS OF Solanum melongena. STRUCTURES OF MELONGOSIDES A, B, E, F, AND H

Three chromatographically individual fractions, each containing tigogenin glycosides and diosgenin glycosides have been isolated by chromatography on a silica gel column from a methanolic extract of eggplant seeds.To separate the mixture of two difficultly separable glycosides into individual components, each fraction was acetylated and epoxidated, and the derivatives obtained were separated chromatographically.The tigogenin glycoside peracetates isolated were saponified, and the diosgenin epoxide glycoside acetates were de-epoxidated and saponified, to give the individual glycosides, melongosides A, B, E, F, and H.The complete chemical structure of each melongoside has been shown with the aid of acid hydrolysis, methylation, and periodate oxidation followed by a study of the products obtained.
STEROIDAL SAPONINS OF ASPARAGUS ADSCENDENS

From the methanol extract of the fruits of Asparagus adscendens sitosterol-β-D-glucoside, two spirostanol glycosides (asparanin A and B) and two furostanol glycosides (asparoside A and B) were isolated and characterized as 3-O-2)-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-2>4)>-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-2)>4)>-β-D-glucopyranosyl>-26-O-(β-D-glucopyranosyl)-22α-methoxy-(25S)-5β-furostan-3β,26-diol and 3-O-2)>4)>-β-D-glucopyranosyl>-26-O-(β-D-glucopyranosyl)-(25S)-5β-furostan-3β,22α,26-triol, respectively.Key Word Index - Asparagus adscendens; Liliaceae; saponins; spirostarol glycosides; furostanol glycosides.

Sharma, S. C.,Sati, O. P.,Chand, R.
, p. 1711 - 1714 (2007/10/02)
Three spirostanol and two furostanol glycosides were isolated from a methanol extract of the roots of Asparagus curillus and characterized as 3-O-4)-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-2)>4)>-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-2)>4)>-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-2)>4)>-β-D-glucopyranosyl>-26-O--22α-methoxy-(25S)-5β-furostan-3β,26-diol and 3-O-2)>4)>-β-D-glucopyranosyl>-26-O--(25S)-5β-furostan-3β,22α,26-triol respectively. - Key Word Index: Asparagus curillus; Liliaceae; saponins; furostanol glycosides; spirostanol glycosides.
