Abstract
Catechin content is the determinant key of quality in gambier trade. The required Catechin content of gambier extracts as a herbal medicinal ingridient is greater than 90%. Mostly, Local gambier that produced by community is not uniform and low quality, thus lowering the price in the export markets. The quality improvement of gambier can be done by extraction and purification processes. This study aims to determine the best extraction process of catechin from Gambier (Uncaria Roxb) which derived from Solok Bio Bio Lima Puluh Kota, West Sumatra. The research methodology includes pre purification: raw materials preparation, washing, filtration, extraction, drying and testing. Washing was done on 100 gr gambier with a variation of water at 500, 600, 700, and 800 ml, heating for an hour at a temperature of 70⁰C, screened, filtered, and allow to stand until a precipitate is formed, wash repeatedly, filtered, and dried. Further, extract with a solvent variation of : water, etyl acetate, heated at 70⁰C temperature for 1 hour, then filtered. Filtrate then thickened by using a Rotary evaporator, dried at 50⁰C temperature for 48 hours and analyzed. The results showed that the best conditions of the extraction process is by using a solvent etyl acetate, at a temperature of 70⁰C, grading 97.40% catechins.
