Saponins and Sapogenins
The seeds of Luffa aegyptica Mill, locally known as "ghia torai" (family Cucurbitaceae), have earlier been studied for the saponin and sapogenin contents and found to contain a mixture of colourless saponins which on hydrolysis yields two acid and a neutral sapogenin. The acetates of the two acid genins melted at 266-268" and 176-181" while the neutral genin acetate melted at 262-264O.l The aci...
متن کاملPreliminary pharmacobiological study of new steroidal sapogenins.
The chemotherapeutic study of a limited series of steroidal sapogenins from several endemic species of the flora of the Canary Islands is presented here. On the whole, they possess a very weak antibacterial activity, a slight antifungal effect and one of them, vespertilin, displays interesting cytostatic activity (ID50 = 5 micrograms/ml). A pharmacodynamic screening carried out on this product ...
متن کاملSaponins and Sapogenins from Brachiaria decumbens Stapf
Quatro saponinas esteroidais e três sapogeninas foram identificadas das partes aéreas de Brachiaria decumbens. As estruturas desses compostos foram estabelecidas através de métodos químicos e espectroscópicos (RMN de H e C, HMBC, HMQC) como 3 -metóxi-lanost-9(11)-eno (1), diosgenina (2a), iamogenina (2b), 3-O-D-glicopiranosil-24(S)-etil-22E-deidrocolesterol (3a), 3O-D-glicopiranosil-24(R)-etil-...
متن کاملRenoprotective Effect of Eryngium Caucasicum in Gentamicin-induced Nephrotoxic Mice
Recent studies show that hydrogen peroxide free radicals have an important role in the renal damage induced by Gentamicin. Previously we studied the hydrogen peroxide scavenging activity of Eryngium caucasicum. This work was conducted to evaluate the possible renoprotective effect of Eryngium caucasicum against Gentamicin-induced renotoxicity. Extracts at the doses 200 and 400 mg/kg/day for 10 ...
