Abstract: An extract from green coffee beans is disclosed which contains polyphenols and bioactive compounds e.g. Chlorogenic acids in a significantly higher concentration (70-80%) than in extracts of prior art methods (40-50%). The extract has greater ability to quench oxidative stress and destroy free radicals and offers health benefits due to its anti-obesity, anti-diabetic, antihypertensive, anti-tumor and anti-acid properties. The higher concentration of bioactive compounds has been achieved by use of polar solvents having polarity less than that of alcohols used for extraction. The use of such solvents of lower polarity such as n-Butyl alcohol, ethyl acetate or acetone results in extraction of enriched Chlorogenic acid fractions into the extract, leaving polar impurities behind in aqueous medium. The extract obtained has significantly higher content of polyphenols and chlorogenic acids ranging from 70-80% and a distinctive HPLC profile.

Abstract: Present invention discloses a novel, commercially viable process for extraction of Alpha yohimbine from the bark, stem and leaves of Rauwolfia species. The extract is obtained by a precipitation method involving alternate steps of acidification and alkalization along with use of specific organic solvents. The extract gives higher yield of 7-8 fold as compared to other processes and without use of any column chromatography at all. Yield of alpha yohimbine from roots and leaves of Rauwolfia canescens by process of present invention was 0.017% and 0.4% respectively, indicating that leaves are a much better source. The HPLC analysis of the compound obtained indicated a purity of >90%.
