A Method For Extraction Of Fractions Containing Pharmacologically Active Ingredients With Less Cytotoxicity From One Or More Plants
Abstract: The invention describes a method of extraction from Withania somnifera (WS) and one or more fractions containing the pharmacologically active ingredients extracted from WS using the method of extraction. A fraction predominantly includes Withaferin-A along with other pharmacologically active ingredients of WS. Another fraction includes additional pharmacologically active ingredients of WS. The method includes soaking a plant material of WS in a mixture of aqueous alcohol and chloroform for a pre¬determined time period and then filtering the mixture to obtain a multi-layered filtrate and a first residue. Thereafter, the multi-layered filtrate is separated into an aqueous alcohol layer and a chloroform layer, Subsequently, the method includes concentrating the aqueous alcohol layer and chloroform layer by evaporation to obtain a hydro-alcoholic fraction and a chloroform fraction. The method further includes dissoluting the chloroform fraction in hexane to get a hexane soluble fraction and a second residue. The second residue obtained by the above method constitutes the fraction including predominantly Withaferin A along with other pharmacologically active ingredients of WS. The hydro-alcoholic fraction obtained by the above method constitutes another fraction including additional pharmacologically active ingredients of WS.
