REVIEW ON NARINGIN: METHOD OF ISOLATION, ANALYTICAL DEVELOPMENT, AND ITS RECENT PHARMACOLOGICAL ACTIVITIES

Naringin is a flavonoid isolated from different citrus fruits like Grapefruit, Orange, Pomelo, Lemon, etc, which are commonly called local fruit. Naringin is found in the white spongy portion of citrus peel. Its content varies from 0.65 mg/gm in the mandarin peel to 14.40mg/gm in the grapefruit peel. Naringin is metabolized to the flavanone naringenin by the enzyme Naringinase present in the liver. It can be analyzed by using various analytical techniques such as HPLC, TLC, UV, HPTLC, mass spectroscopy, Liquid chromatography, chiral chromatography and LC/Mass spectroscopy. Naringin can act as an antioxidant and scavenge free radicals. Naringin mainly focuses on in-vitro and in-vivo animal studies showing its beneficial effects on cardioprotective, antioxidant, anti-inflammatory, antimicrobial, hypolipemiant, neurological, thermogenic, pulmonary disorders and antidiabetic. Naringin is also treated as a most promising treatment strategy against Covid-19 due to its antiviral and anti-inflammatory effects. Recently, Naringin has proven its activity in various molecular docking studies. Naringin keeps the body healthy against various illnesses and major lifestyle disorders.
