Qualitative analysis of the components in camphor tree fruit's red pigments
In order to develop and utilize the rich red pigments resources for the camphor tree's fruit, separating by silica-G thin-layer chromatography(TLC) on the pigment from the camphor tree fruit, we could get three independent and very distinct chromatogram items. Based on such overall studies as the developing in 0.1% HCl-MeOH Solution, detennination of ultraviolet-visible absorption spectrum, reaction with AlCl3, calculating A440/Amax ratio, PC, TLC and so on. It can be deduced that all the main structure of the three components of the pigments in camphor tree fruit are peonidin. Arbinoside and all of them have been replaced in the third place. The pigment is dark-red. It can be used as a natural healthy pigment-additive.
