A PROCESS FOR THE ISOLATION OF FRACTION CONTAINING SIXTEEN CONSTITUENTS MAINLY CONTAINING FLAVANOIDS amp; GLYCOSIDES POSSESSING ADAPTOGENIC ACTIVITY FROM PLANT CENTELLA ASIATICA

摘要

Isolation of fraction possessing adaptogonic activity from plant centella asiatica comprises : i) Crushing and homogenising of fresh whole plant of C.asiatica. ii) Extracting the said homogenised plant using an aqueous alcohol. iii) Concentrating the said aqueous alcoholic extract to minimum volume by conventional method and partitioning with different organic solvents of increasing polarity and drying the polar fraction completely, iv) Subjecting the said polar fraction to conventional chromatographic method employing silica gel of mesh size 230-400.
