CHANGES IN THE TRITERPENE CONTENT DURING STORAGE OF THREE APPLE CULTIVARS
The triterpenes, oleanolic acid, OA and its isomer, ursolic acid, UA are important phytochemicals in apple fruit. In order to investigate the influence of cold storage and cultivar differences on the content of major triterpenes in apple peel, the total content of oleanolic acid and ursolic acid were analyzed by HPLC. It was found that the late ripening cultivar Gloster had higher triterpene content as compared with the early ripening cultivar Discovery and the middle ripening cultivar Aroma. The short-term cold storage did not show any significant influence on the triterpene content in any of the three cultivars.
