Abstract

Plants have served human beings as a natural source for treatments and therapies from ancient times, amongst them medicinal herbs have gain attention because of its wide use and less side effects. In the recent years plant research has increased throughout the world and a huge amount of evidences have been collected to show immense potential of medicinal plants used in various traditional systems. Rosa indica symbol of godness and beauty known for various healing power, has astringent, sedative, anti-inflammatory and antidepressant qualities. The aim of the present study was to evaluate in vitro antioxidant activities of leaves of Rosa indica. The in vitro antioxidant activity of methanolic extract of the leave part was assessed against DPPH free radical scavenging assay methods using standard protocols. The activities of methanolic leave part extract against DPPH assay method were concentration dependent with IC 50 values of ascorbic acid and extracts 24.34 and 62.66μg/ml respectively. The diverse array of phytochemicals present in the plant thus suggests its therapeutic potentials which may be explored in drug manufacturing industry as well as in traditional medicine.
