| Abstract: | By the method of ethanol refluxing, we can get the 25% catechin crude extracts, separate and purify the catechin crude extract by metal ions precipitation and resin adsorption,with purity of 91.45%. Using metal ions precipitation-resin adsorption method for separation and purification of catechin which extraction from pine needle by ethanol reflux method, the process is simple, high yield, low cost, environ- mental health, and has a good application prospect. |
