Abstract
India is the leading producer of fruits worldwide. The major problem after citrus fruits consumption is
their peel that are hazardous to our environment and mainly regarded as a solid waste however, they are
rich sources of fibres, large amount of Vitamin C, phenolics and flavonoids which are best agents of
antioxidant. In this paper, we have discussed about the orange peel waste which has many beneficial roles
in our daily life. Citrus peel has the highest number of Phytochemicals such as flavonoids, terpenoids,
quinolines and having highest antioxidant activity as compared to the pulp and seed as well as identified
from the extraction. The different Phytochemicals test analysis have been discussed in this paper
(steroids testing, saponins testing) and different antioxidant test used to check the antioxidant activity of
the citrus fruit peel extract are Hydrogen peroxide scavenging test, Nitric oxide scavenging test, DPPH test
etc. The main objective of this paper is that the higher antioxidant activity of different mixture of Citrus
fruit peel can help to reduce the generation of free radicals and can act as an anti-proliferative agent. The
search for novel drugs and alternative medicine especially against cancer has led to increased research in
medicinal plants. This review also indicated that Citrus peels contains antioxidant compounds which
could be exploited as value added products in the food and cosmetic industry
