 The aim of this work was to determine the content of total polyphenols, total flavonoids, total monomeric anthocyanins, total proanthocyanidins, and antioxidant activity of Crataegus monogyna L. fruit in water, hydroalcohol and alcohol extracts. Phenolic content and antioxidant assay of the different fruit extracts was determined using spectrophotometric methods. Obtained results indicated that the content of total polyphenols in the investigated extracts varied from 2.01 to 4.60 mg GAE g-1 of fresh hawthorn fruit. The content of flavonoids ranged from 0.254 to 0.595 mg RUE g-1 fresh fruit extracts. Total monomeric anthocyanins varied from 0.004 to 0.132 mg cyanidin-3-glucoside g-1 of fresh fruit and total proanthocyanidins varied from 0.187 to 1.168 mg cyanidin chloride g-1 fresh fruit. The best antioxidant activity was obtained for hawthorn extract with 80% methanol. A good correlation between antioxidant activity and total polyphenols (R² = 0.9473) and proanthocyanidins (R² = 0.7469) was observed.
Highlights
UvodCrataegus L. is a polymorphic genus from Rosacea family, native to northern temperature zones including North America, East Asia, Central Asia, and Europe
The main group of active compounds in hawthorn extracts are flavonoids represented by procyanidins, flavones and flavonols
Water and ethanol are used in manufacturing different pharmaceutical preparations from hawthorn fruits (BERNATONIENE ET AL., 2008)
Summary
UvodCrataegus L. is a polymorphic genus from Rosacea family, native to northern temperature zones including North America, East Asia, Central Asia, and Europe. The purpose of the presented study was to evaluate content of phenols, flavonoids, monomeric anthocyanins, and proanthocyanidins in extracts of different polarity prepared from fresh fruits harvested from native trees of C. monogyna near Sarajevo.
