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...
