The Quanlity Dedermintion of PC in Lethicin Function Foods

Abstract

Abstract: To develop an accurate、rapid method to determine the quantity of the main ingrediant PC in lethicin function foods. Extracting lethicin with hexane,then adding 0.5%iodide-hexane and reacting,absorbance was detected by UV spectrophotometry at a wavelength 292nm. The absorbance calibration curve of PC was in good linearity over the range of 0.35～1.1, r=0.9994(n=5). The method is accurate,rapid simple and suitable to determine the quantity of PC in lethicin function foods.

Key words: Lethicin, PC, UV spectrophotometry, quantitive determination
