Sea buckthorn (Hippophae rhamnoides L.) is widely used for soil, water, and wildlife conservation and anti-desertification purposes. The natural and climatic conditions of Kyrgyzstan make it possible to grow sea buckthorn in forest areas, particularly in sea and river coasts, in dry-sandy semi-desert sites, and high mountains. Walnut-fruit forests of Kyrgyzstan are unique for their great biological and genetic diversity, and constitute natural plantations of sea buckthorn. In Kyrgyz folk medicine, sea buckthorn is used for gastrointestinal system disorders and healing of burn wounds. Unfortunately, information on biologically active compounds, antioxidant activity of sea buckthorn berries from walnut-fruit forest of Kyrgyzstan in the scientific literature is very limited. This study aimed to investigate the chemical composition (dry matter, sugars, pH, titratable acidity, ash, fibre, vitamin C) and the radical scavenging activity, total polyphenols of sea buckthorn berries for documentation in the national food composition database and comparison with the all available recent studies on sea buckthorn.
