Abstract

The extracts (n-hexane and chloroform crude extracts) of Callistemon linearis (Family-Myrtaceae) were subjected to antimicrobial screening and brine shrimp lethality bioassay. In case of antimicrobial screening, the n-hexane, and chloroform crude extracts exhibited very prominent antimicrobial activity against most of the test organisms while from the results of the brine shrimp lethality bioassay, it can be well predicted that the n-hexane extract showed highly cytotoxic potency due to 100% mortality over whole concentration range in which cytotoxicity screening was done whereas chloroform crude extract showed moderate cytotoxic potency with LC90 of 30.90 g/mL.
