Determination of the quantitative composition of triterpenic compounds and antiradical activity in vitro of decorative apple fruit samples

Introduction. Apples are one of the most important and widely consumed fruits, rich in valuable nutrients [1]. Apples are used to make many products such as cider, juice, jams, compotes, tea, wine and dried apples [1]. Apples are the important part of the human diet [1]. They have a wide range of biologically active compounds beneficial to the human body which strengthen the immunity and protects against oxidative stress [1]. Decorative apple fruits contain many bioactive compounds such as phenolic compounds, flavonoids [2], triterpenic compounds [3], etc. The triterpenic compounds include ursolic acid, which has anticancer, antioxidant and anti-inflammatory features [3], oleanolic acid, which has hepatoprotective features [4], and a number of other triterpenic compounds. In this study, 19 different apple varieties were analysed for triterpenic compounds and antiradical activity. [...].
