The purpose of this study was to isolate soy lecithin from soy sludge by bleaching it with hydrogen peroxide give treatment with calcium chloride and finally dried. Standardization of soy lecithin was done by TLC analysis and other official tests like acid value, hexane-insoluble matter, acetone-insoluble matter etc. The behavioural study was done on albino rats, it included forced swim test and elevated plus-maze test. Soy lecithin was successfully isolated economically from soy sludge and all parameters for which it was evaluated were within specified limits Chromatographic and FTIR-spectrophotometric analysis of soy lecithin suggested the presence of triglycerides, free fatty acids. Results obtained from the behavioural study performed on albino rats indicate that soy lecithin has potent anti-depressant activity, which mainly have been contributed by its chief constituent, phosphatidylcholine.
