| titleOfInvention | (3-β), 4-α, 16-β)-16, -23, 28-trihdroxyolean-12-ene-3-yl-β-D-glucopyranuronic acid derivatives, as glucose absorption inhibiting agents |
| abstract | The present invention relates to (3 beta , 4 alpha ,16 beta )-16,23,28-trihydroxyolean-12-ene-3-yl- beta -D-glucopyranuronic acid derivatives and a method for preparing the same from Gymnema inodorum leaves, which comprises treating Gymnema inodorum leaves with an aqueous acid solution, extracting the leaves with an alcohol and/or water, concentrating the extract and subjecting to liquid-liquid partition extraction with water and 1-butanol, concentrating and drying/caking the 1-butanol phase under reduced pressure, defatting the cake, extracting soluble components from the cake with a high polar solvent, concentrating and drying/caking the extract to obtain a purified Gymnema inodorum leaf extract, and then applying the purified extract to HPLC to obtain fractions containing glucose absorption inhibiting substances. |
