Abstract:From prehistoric era, the plants are used as a healing for many alarming disease due to the presence of therapeutic value. Even in contemporary invention, many herbal plants are intent in research field to concise about the efficacy of plant in curing disease with fewer side effects in long term exposure. Physalis minima Linn is generally used in the indigenous system of medicine for various diseases like diuretic, fevers, etc. In the present study, an attempt was made to evaluate the phytochemical substances and bioactive compound of the aqueous methanol extract of unripe fruit of Physalis minima Linn. The crude extract was separated by soxhlet using methanol as solvent followed by the phytochemical screening to identify the presence of secondary metabolites. Volatile components present in the methanol extract were separated and identified using GC/MS. The Gas chromatography - mass spectrometry chromatogram result showed the presence of total of 18 bioactive compounds in crude extract of physalis minima Linn which are exhibiting different biological functions such as antioxidant, anti-inflammation, anticancer, antidiuretics etc. Antibacterial activity of Physalis minima Linn extracts were also studied using disc diffusion method. The activities of methanol extracts were tested and had showed good inhibition zone against Staphylococcus aureus.
