Martynia annua (cat’s claw, bichu) is part of Martyniaceae family. For centuries, extracts of leaves, roots, stems, fruits and seeds of M. annua have been used to cure eplilepsy, inflammation, tuberculosis, skin infections etc. Present investigations revealed qualitative phytochemical screening and bioactivites of fruit extracts of M.annua in solvents of different polarties. The qualitative phytochemical analysis exhibited the presence of alkaoids, flavonoids, glycosides, saponins, tannis, anthocyanins, steroids, amino acids and phenols. DPPH (1.1-diphenyl-2-dipicryl hydrzal free radical scanvenging, reducing power assay and lipid peroxidation inhibition assay likability in different solvents were explored which revealed that with increase in concentration of extracts resulted increase in degree  of reduction.  The outcome of the present studies revealed that the fruit extracts of M. annua have eminent antioxidant activity https://www.biotech-asia.org/vol14no4/antioxident-activities-and-phytochemical-screening-of-martynia-annua-fruit-extract/  Antioxidant; DPPH;Lipid  Martynia Annua; Phytochemical Screening; Peroxidation Inhibition; Reducing  Power Assay
