NOVELTY - Combined preparation of rosolic acid and tormentic acid, comprises e.g. extracting a medicinal material from a solid male fruit and then crushing, adding 40-70% of ethanol for 2-3 times, mixing the extracting solution, removing the impurity from the solution using macroporous resin, processing the extract with the macroporous resin, primarily eluting sugar and other impurity with water and water solution having low concentration of water soluble organic solvent, and secondarily eluting with water solution having high concentration of water soluble organic solvent.    USE - The rosolic acid and tormentic acid are useful for treating diarrhea, dysentery and diabetes. No biological data given.    ADVANTAGE - The method is capable of economically and efficiently preparing a combination of euscaphic acid and tormentic acid with high purity and good quality in an environmental friendly manner.    DETAILED DESCRIPTION - Combined preparation of rosolic acid and tormentic acid, comprises extracting a medicinal material from a solid male fruit and then crushing, adding 40-70% of ethanol for 2-3 times, mixing the extracting solution, removing the impurity from the solution using macroporous resin, processing the extract with the macroporous resin, primarily eluting sugar and other impurity with water and water solution having low concentration of water soluble organic solvent, secondarily eluting with water solution having high concentration of water soluble organic solvent, decompressing and concentrating the eluant to obtain the total triterpene extract, preparing the high-efficiency liquid phase for separating and purifying the resulting solution using the methanol for dissolving the total triterpene extract, filtering via a film using the high-efficiency liquid phase prepared color spectrum for separating and purifying, respectively collecting the target washing liquid and the reagent to small volume, recrystallizing and thermally reflowing and crystallizing the methanol for 2-3 times to obtain the rosolic acid and tormentic acid, where the ratio of the medicinal material and the solvent is 1:5-10.
