A PROCESS FOR THE ISOLATION OF URSOLIC ACID FROM EUCALYPTUS HYBRID (LEAVES)

摘要

This invention relates to a process for the preparation of ursolic acid comprising the step of chopping Eucalyptus hybrid leaves, subjecting the chopped leaves to the steps of selective extraction with polar solvents, such as methanol, ethanol, water and chloroform, acetone, ethylacetate, concentrating the extract on a water bath maintained at 80°C to 95°C to obtain a modified extract, subjecting the solid containing extract to step of Alteration and washing with solvent of extraction to obtain ursolic acid.
