NOVELTY - Extracting and separating triterpenoid and ellagic acid compounds from Lathyras sativus leaf cone and flowers involves taking leaf cone as raw material and acetone as solvent and extracting; recycling acetone and filtering to obtain filter liquid; subjecting to column chromatography using macroporous resin, washing with water, washing column with 20-50% organic solvent, washing with 70-100 wt.% organic solvent to elute phenol eluent, reacting, collecting eluent from 80-100 wt.% of organic solvent; decompressing eluent, recovering solvent, cooling, and separating out crystal.    USE - For extracting and separating triterpenoid and ellagic acid compounds from Lathyras sativus leaf cone and flowers (claimed), where Lathyras sativus is widely used for treating cardiovascular and cerebrovascular diseases, stopping bleeding, stopping diarrhea, and chronic ulcer disease.    ADVANTAGE - The method effectively uses macroporous resin column chromatography, improves the yield of the product and reduces cost, where yield reaches more than 0.37%. The method provides product of high purity, is simple, has easy operation, and is easy to be industrialized.    DETAILED DESCRIPTION - Extracting and separating triterpenoid and ellagic acid compounds from Lathyras sativus leaf cone and flowers involves: taking primarily Lathyras sativus leaf cone as raw material, and acetone as solvent and subjecting to extraction process to form extraction liquid; recycling acetone from extraction liquid and filtering to obtain filter liquid; subjecting the obtained filter liquid to column chromatography using macroporous resin, washing with water, and then washing with 20-50% organic solvent, washing with 70-100 wt.% organic solvent to elute eluent liquid of phenol, reacting, collecting eluent from 80-100 wt.% of organic solvent solution, where the macro-porous resin is D-101, AB-8, HPD500, HPD600, D-4020 or HP-20, and the organic solvent is methanol, ethanol or acetone; decompressing collected eluent and recovering the organic solvent until a crystal is formed, cooling, standing, and separating out crystal to obtain the triterpenoid and ellagic acid compound.
