Abstract
Mazkur tadqiqot ishida “As-Capsipol” oziq-ovqat qo‘shimchasi tarkibidagi askorbin kislotasi (vitamin C) miqdori yuqori samarali suyuqlik xromatografiyasi (YuSSX) usuli yordamida aniqlangan. Tadqiqot jarayonida standart modda sifatida L-askorbin kislotasi qo‘llanilib, namuna ekstrakti kislotali muhitda ultratovush yordamida ekstraksiya qilindi. Xromatografik tahlil Shimadzu kompaniyasining LC-40 Nexera Lite yuqori samarali suyuqlik xromatografi yordamida amalga oshirildi. Olingan natijalar asosida askorbin kislotaning retensiya vaqti, pik maydoni, pik balandligi hamda konsentratsiya ko‘rsatkichlari hisoblab chiqildi. Tahlil natijalariga ko‘ra vitamin C ning retensiya vaqti o‘rtacha 4,162 minutni tashkil etib, analizlar yuqori takrorlanuvchanlikka ega ekanligi aniqlandi. “As-Capsipol” oziq-ovqat qo‘shimchasida askorbin kislotaning miqdori 0,445–0,468 mg/l oralig‘ida aniqlanib, o‘rtacha 0,460 mg/l ni tashkil etdi. Olingan natijalar YuSSX usulining vitamin C ni aniqlashda yuqori aniqlik va selektivlikka ega bo‘lgan samarali analitik metod ekanligini ko‘rsatdi.
