320DETERMINATION OF TOTAL PHENOLIC CONTENT AND TOTAL PROTEIN IN GUAVA (Psidium guajava) AND LEMON (Citrus limon)Phenolic compounds are a large group of secondary plant metabolites. Fruits are rich with antioxidants that help in lowering incidence of degenerative diseases such as cancer, arthritis, arteriosclerosis, heart disease, inflammation, brain dysfunction and acceleration of the ageing process. Wide adaptation of guava to diverse environmental conditions, along with its unique characteristic of possessing a storage protein. Domestic lemon is generally propagated by grafting, although some are grow readily from seed. Many different phenolic compounds have been identified in guava. The two main subtypes of polyphenols are flavonoids and phenolic acids. The present study reveals the total phenolic content and total protein in guava (Psidium guajava) and lemon (Citrus limon).asharako@rediffmail.comResearch4112013Phenolics,Metabolites,Flavonoid,Total proteinsSharma Asha,Sindhu Pawan,Devi AnnuDepartment of Botany, M.D.University Rohtak-124001.,Department of Botany, M.D.University Rohtak-124001.,Department of Botany, M.D.University Rohtak-124001.
