ABSTRACT
Plectranthus amboinicus is a commonly available medicinal herb in India. The phytochemical active compounds qualitatively analyzed such as alkaloids, Terpenoids, Cardiac glycosides, saponin, tannins and flavonoids present in Plectranthus amboinicus. The aqueous, acetone and methanol crude plant extracts were prepared and tested against gram positive and gram negative bacteria. The highest antibacterial activities were observed in methanol extract (11± 0.19, 16± 0.45, 15±0.57, 17±0.23, 16± 0.48, 10±0.38 and 16±0.66 mm in diameter) compared than acetone extract (6.0 ± 0.18, 6.0 ± 0.18, 6.0 ± 0.18, 6.0 ± 0.18 mm in diameter). There is low antibacterial activity in aqueous extract.
