SCREENING OF SOUTH INDIAN HERBS FOR QUORUM QUENCHING PROPERTY.

Abstract

All bacteria communicates by a process called Quorum sensing. In which the bacteria  secrete  small  molecules  are  called  auto  inducer  that  acts  a  molecular “Messenger”, the auto induces increase with increase in bacterial population and are able to involve in Quorum sensing only after reaching a threshold. Concentration anti quorum sensing agents.   Would  offer   ofcontrolling   microbial   infection   with advantages of reducing risk of resistance development. The continuing search for new and novel anti microbials and anti pathogenic  agents has focused on exploiting the fact that plants serving in an environment with high bacterial density has been seen to posses productive means against infection. Naturalproducts especially south Indian folk plants shows the promising results in curing of diseases and bacterial infections in this study 15 plants were investigated and all the plants shows the activity in which Termanalia chebula was found to be a leading plants followed by awsonia inermis, solanum torvum, termanalia arjuna.
