Perusal of literature reveals that no such works on nutraceutical properties has been done on the landraces of
Capsicum spp. from Assam. With this backdrop the present investigation was taken up for phyto-chemical
analysis of 24 local landrace variants of Capsicum spp. Out of these 24 landraces, 17 are C. annum, 05 landraces
are C. frutescens and 02 landraces are C. chinense. Macro and micro nutritional studies like carbohydrates, total
soluble protein, fats, crude fibre, oleoresin, flavonoid and ascorbic acid, total mineral in the form of ashes, total
phenolics and antioxidant activities were carried out. Experimental results exhibited the maximum value of the
test findings as carbohydrate 6.2%, total soluble protein 3.63%, total fat 1.6%. Crude fibre 11.1%, oleoresin
5.8%, flavonoid 26.41 µg QE mg-1, total minerals in the form of ash 5.9%, total phenolic content 131.8 µg GAE
mg-1, vitamin C (in the form of ascorbic acid) 179.2 mg/100g. The methanolic extract for determining the
anti-oxidant activities (IC50) of all the samples of Capsicum were ranging from 134.0 to 62.2µg mg-1 that can
reduce 50% reactive oxygen species (by DPPH method). Investigation reveals that apart from the
macronutrients, the micronutrients like phenolic compounds, vitamin C, flavonoids and oleoresin are found to
be rich in the fruits of Capsicum spp. which leads to the antioxidant property. So, the fruits can be suggested as
dietary supplement for human health benefit. Also, there is a scope of therapeutic use of the fruits in
traditional medicines.
