This study aimed to conduct an ecological and biological survey of natural populations of sea buckthorn and select promising forms in the Burabai National Park of the Republic of Kazakhstan. The selection was based on the pomological and antioxidant properties of six forms (Hr-01, Hr-02, Hr-03, Hr-04, Hr-05, and Hr-06). The results showed that the highest fruit weight was found in form Hr-1 (21.7±0.8 g), and the lowest fruit weight was found in form Hr-5 (9.3 g±0.09). Fruit length ranged from 5.6 to 8.4 mm, diameter ranged from 4.1 to 6.1 mm, and weight ranged from 9.3 g to 21.7 g. The highest content of total polyphenol was found in forms Hr-04, Hr-02, and Hr-05 (13.60, 12.82, and 12.68 GAE/g, respectively). According to the results of DPPH and FRAP tests, four sea buckthorn forms had high antioxidant activity (Hr-06, Hr-05, Hr-02, Hr-01). The results revealed significant variation in fruit size, weight, and antioxidant activity among the forms. Forms Hr-01, Hr-02, and Hr-06 showed superior pomological characteristics, while Hr-05 and Hr-06 exhibited the highest antioxidant activities and polyphenol content. These selected forms demonstrate potential for further research under ex-situ conditions for applications in agriculture and health promotion.
