Hydrotropic Extraction of Xanthones from Mangosteen Pericarp

Article Preview

Abstract:

A novel separation process for extraction of xanthones from mangosteen pericarp was investigated using aqueous hydrotrope solution. The hydrotropes sodium salicylate was used for the extraction. The effects of factors such as hydrotrope concentration, extraction temperature and solid loading were investigated by using Response Surface Methodology (RSM). The optimal conditions to obtain the highest yield of xanthones were 2M sodium salicylate, extraction temperature of 40°C and 3% solid loading. This hydrotropic extraction technique is simple and cost effective for the separation of bioactive compounds.Key words: Xanthones; Hydrotropes; Hydrotropic extraction
