Kodupuganti Nandini and Dr. B. Anil*
ABSTRACT
Azadirachta indica, which was the scientific name of Neem that belongs to Meliaceae family, mostly found in South Asia (India, Pakistan, Bangladesh and Nepal). The average height of Neem includes 29m to 30m with the diameter of 4-5feets. Leaves are imparipinnately arranged with 5 to 15 leaflets and the fruits are yellow-green drupes. The study of Neem is to determine the antioxidant activity, nutritional analysis (vitamin C, vitamin E, Mg, Ca and Fe), phytochemical analysis (total phenolic content, alkaloids, flavonoids, saponins, tannins and phytates), anti-diabetic and anti-microbial activity. The results of Neem fruit showed as Antioxidant activity by FRAP is 9.797micromol, by DPPH is 1279ppm and by ABTS is 76.05 GAE/g of inhibition against free radicals. The vitamin C is 1.73mg, vitamin E is 49mg, magnesium is 45mg, calcium is 7.3mg, iron is 102mg and potassium is 89mg. Antimicrobial activity is 100CFU/g and total phenolic content is 66.32GAE/g. Antidiabetic activity is high due to carbohydrates present in it. Saponins are more in number than tannins, alkaloids, flavonoids and phytates. Neem helps to maintain liver, kidney, hair, dental, skin and heart health. Neem is used as an insect and mite repellents and also as pesticides. Neem has anti-inflammatory, anti-arthritic, anti-pyretic, anti-fungal, anti-bacterial, anti-tumour and anti-fertile properties.
Keywords: Neem Seed, Neem Pulp, Antioxidant Activity, Nutritional Analysis, Total Phenolic Content.
