Easily browned litchi pericarp was chosen to study the extraction effects of chorophll, carotenoid and chorophll b/chorophll a. Different extraction methods showed different results with the same material. The absorption spectrum characteristics were subsequently subjected to study. Results displayed that only that of extraction methods used with ether was accordance with the former reports.The other related extractions showed higher aptical density and there were irregular unknown absorbance peaks appeared around the wavelength of 350 nm.
