Capsicum annuum is a beneficial vegetable crop belongs to Solanaceae family, and is in demand for the abundance of vitamins and antioxidants which include phytochemical and Polyphenol. It is vulnerable to the attack of various pathogens like bacteria, virus and fungus. But incidence of plant viruses become prominent in Capsicum crop day by day in India and are one of the several factors responsible for loss of yield and quality of Capsicum crop. Losses caused by virus diseases are less perceivable than bacterial and fungal diseases. Viruses’ infection causes metabolic and biochemical changes in plants. In order to detect the different virus that infect Capsicum crop and analyse their effect on its phytochemical constituents, a survey was conducted for sample collection on the basis of symptoms .All the collected samples were checked for the presence of virus infection through DAS-ELISA and RT-PCR. The tested samples showed positive result for CMV, PVX, PVY, TYLCV, GBNV and PSTVd. Thus, indexing showed that these were the common viruses in Himachal Pradesh, India that infect capsicum crop. All the samples showed positive result for virus were tested for phytochemical compounds. Phytochemical analysis showed that antioxidant activity, total carotenoids, total chlorophyll and ascorbic acid content were reduced significantly, whereas, total phenols and total flavonoids increased in virus infected samples. Thus, this analysis reflect the presence of virus and changes of nutritional status of capsicum under virus infection
