Abstract
Pogostemon auricularius (L.) Hassk is a weed has various medicinal value. The present study describes the antimicrobial and antioxidant activity and phytochemicals present in different aerial parts of the plant. Flavonoids, terpenoids, steroids, glycosides, cardiac glycosides, reducing sugar and phenols are sampled in all the parts. Methanol extract of inflorescence had highest phenol and flavonoid content. Methanol extract of mature leaves had highest antioxidant inhibition against ABTS. Hot petroleum ether extract of mature leaf against B. subtilis recorded Zone of Inhibition of 24±2mm which is higher than standard antibiotics like-Chloramphenicol (15±2mm), Clotrimazole (20±0mm) and Streptomycitin (18±0mm). It can be concluded that methanol extract is more potent than the other solvent used. The study suggests that instead of using whole plantwhole plant, specific parts can be used for sustainable management of medicinal plants.
