Analysis and Evaluation for Dynamic Accumulation of Multicriteria Chemical Compositions from Ligustrum lucidum Ait. in Different Mature Periods

OBJECTIVE To analyze and evaluate the dynamic accumulation of multicriteria chemical compositions from fruits Ligustrum lucidum Ait.in different mature periods.METHODS Triterpenes,split ring iridoid glycosides,phenethanol and carbohydrate from fruits Ligustrum lucidum Ait.in different mature periods were detected by HPLC and visible spectrophotometric method to evaluate the results by the application of comprehensive grading method which analyzes the main compositions.RESULTS The chemical compositions from fruits Ligustrum lucidum Ait.in different mature periods differed significantly;Oleanolic Acid,maloic acid and nuezhenoside may be the main factors determing the quanlity of fruits Ligustrum lucidum Ait.CONCLUSION The last ten-day period of October is suggested to be the best picking time for fruits Ligustrum lucidum Ait.produced in Nanjing of Jiangsu province.
