| Popis: | International audience; In the conditions of the Republic of Belarus there was realized identification of anthocyanins, estimation of their total content in blackberry (Rubus fruticosus L., Rubus caesius L. and Rubus nessensis W. Hall.) and raspberry \{Rubus idaeus L.) as well as the evaluation of fruit antioxidant activity. A total of 17 anthocyanins were detected and identified by HPLC-MS analysis. The aglvcon forms were represented by five anthocyanidins: cyanidin, delphinidin, pelargonidin, petunidin and malvidin. The prevalent sugar moieties were glucose, galactose, arabinose, rutinose, sophorose and sambubiose. Significant differences between the qualitative composition of anthocyanins have been detected in examined fruits. Total anthocyanins ranged (in mg cyanidin 3-O-glucoside per 100 g of fresh weight) from 95.72 to 538.48. Mean values of antioxidant capacity by ABTS and ORAC methods (in mmol Trolox equivalent per 100 g of fresh weight) were 3.41-8.17 and 2.26-4.77 respectively. Mean FRAP values varied from 5.35 to 10.67 mmol Fe2 +/100 g FW of fruits. On the based of our data the recommendations on practical application of fruits were proposed. |
