Abstract
Ushbu ilmiy izlanish doirasida madaniylashtirilgan yong‘oq (Juglans regia L.) meva mag‘zining metabolik profili, uning lipid-oqsil nisbati va mikronutrientli xususiyatlari, shuningdek, ularning inson fiziologik funksiyalariga mumkin bo‘lgan ta’siri tahliliy o‘rganib chiqildi. Usullar. Lipidlar Soxhlet qurilmasida n-geksan yordamida ajratib olindi, yog‘ kislotalari tarkibi gaz-suyuqlik xromatografiyasi (GC-FID) vositasida, umumiy azot miqdori modifikatsiyalangan Kyeldal usulida, mineral elementlar ICP-AES yordamida, vitaminlar va polifenol moddalar esa teskari fazali yuqori samarali suyuqlik xromatografiyasi (RP-HPLC) orqali aniqlandi. Natijalar. Metodologik tahlillar natijasida meva mag‘zida yog‘ lipidlari ulushi 61.0–72.0% to‘plamida, oqsil makromolekulalari 17.0–20.0% diapazonida, strukturaviy polisaxaridlar (oziq-ovqat tolalari) esa 6.0–8.5% oralig‘ida namoyon bo‘lishi aniqlandi. Ekstraksiya jarayonida organizm metabolizmi uchun zarur bo‘lgan ko‘p to‘yinmagan polien kislotalar (alfa-linolen va linol kislotalar turkumi), jumladan, hayotiy muhim vitaminlar (A, C, E, B guruhi komplekslari) hamda mikro-makroelementlar (Mg, Fe, Zn, K) konyugatsiyasi belgilandi. Xulosa. Tokoferol va polifenollarning birgalikda mavjudligi mag‘izning erkin radikallarni neytrallovchi antioksidant salohiyatini, oziq-ovqat tolalari esa hazm qilish trakti motorikasini faollashtirish imkoniyatini asoslaydi.References
