Piperine is the active principle of black pepper responsible for its pungent characteristic and it reportedly possesses several physiological effects.

The in vitro antimicrobial activity of toluene extracts of pepper were checked by disc diffusion method [10]. Information For Readers For Authors. As the plant has great adaptability towards various soils and climatic conditions so there will be a ot inter species diversity [3]. Toluene extract kept for around three and half months, separated into upper brown coloured oily layer and rod shaped shiny crystals settled at bottom of the beaker.

During the research for novel, bio active natural products, the dried and crushed seeds of the plant were successively soxhlated with the light petroleum ether, soectra, chloroform and alcohol on their polarity gradient.
