Annotatsiya: Ushbu maqolada odatda dalada qolib ketadigan sabzi (Daucus carota L.) poyasi va barglaridan fitontsidli ekstraktlar olish hamda ularni tabiiy konservant va o‘simliklarni himoya qilish vositasi (biopestitsid) sifatida qo‘llash imkoniyatlari chop etilgan ilmiy manbalar asosida tavsifiy (narrativ) sharh shaklida tahlil qilindi. Sabzi barglari fenol birikmalar, flavonoidlar, askorbin kislota va karotinoidlarga boy ekanligi aniqlandi. Ekstraksiya sharoitiga qarab umumiy fenollar miqdori 13,40–144,56 mg GAE/g quruq ekstrakt oralig‘ida o‘zgaradi, 70% etanolli ekstrakt esa issiq suvli ekstraktga nisbatan yuqori fenol, flavonoid miqdori va kuchliroq antioksidant faollik ko‘rsatadi. Antimikrobial faollik bo‘yicha ma’lumotlar cheklangan: turli barg ekstraktlarida ingibirlanish zonalari Staphylococcus aureus uchun 0–15 mm, Escherichia coli uchun 0–13 mm, Candida albicans uchun 0–11 mm va Aspergillus niger uchun 0–8 mm oralig‘ida qayd etilgan. Sabzi barglari ekstraktini oziq-ovqat mahsulotlarida konservant sifatida yoki fitopatogenlarga qarshi biopestitsid sifatida qo‘llash bo‘yicha to‘g‘ridan-to‘g‘ri eksperimental ma’lumotlar ko‘rib chiqilgan manbalarda topilmadi, shu sababli bu yo‘nalishlar gipoteza sifatida baholandi. Kelgusi tadqiqotlar uchun standartlashtirilgan eksperimental protokol taklif etildi va ekstraktning toksikologik xavfsizligini baholash zarurligi ta’kidlandi.
