متن کاملSaponins 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...
