Ushbu maqolada pista (Pistacia vera L.) poʻchogʻidan biologik faol fenolik birikmalarni ekstraksiya qilish usullari hamda olingan ekstraktlarning antioksidant faolligi ilmiy jihatdan tahlil qilindi. Pista qayta ishlash jarayonida hosil boʻladigan poʻchoq fenolik kislotalar, flavonoidlar, gallotanninlar va boshqa biologik faol komponentlarning istiqbolli manbai hisoblanadi. Tadqiqotlarda ekstraksiya erituvchisining qutbliligi, harorat, ekstraksiya davomiyligi, xomashyo va erituvchi nisbati hamda ultratovush yoki tezlashtirilgan ekstraksiya texnologiyalarining fenolik moddalarni ajratib olish samaradorligiga sezilarli taʼsir koʻrsatishi aniqlangan. 2026-yilgi tadqiqotda tezlashtirilgan erituvchi ekstraksiyasining optimallashtirilgan sharoitida fenolik birikmalar miqdori 9,92 ± 0,09 g GAE/100 g quruq modda va DPPH boʻyicha IC50 0,16 ± 0,00 mg/ ml ni tashkil etgan. Ekstraktda gall kislotasi asosiy fenolik komponentlardan biri boʻlgan. Natijalar pista poʻchogʻini tabiiy antioksidantlar olish uchun qimmatli ikkilamchi xomashyo sifatida qayta ishlash imkoniyatini koʻrsatadi.Keywords
