Aims: The Canthium parviflorum Lam. is an important medicinal plant extensively used in traditional oriental herbal medicines. It is important to screen for the novel biological activities and novel chemical constituents to further validate the use of this plant extract. This was mainly intended to screen in vitro pharmacological activities with callus extracts of Canthium parviflorum.  Experiments were designed according to the standard methods and processes.

Place and Duration of Study: The Pharmacology Department of Laila Research Centre in Vijayawada, Andhra Pradesh, India between September-October 2012.

Methodology: Callus was induced from leaf explants of Canthium parviflorum on MS medium supplemented with 2,4-Dichlorophenoxyacetic acid and the compounds were extracted from dried callus using methanol solvent with Soxhlet apparatus.

Results: The Graph pad Prism Version‑5 software was used to analyze data in the form of figures. The callus extract was potentially inhibited the 5- Lipoxygenase inhibitory enzyme at significantly less IC₅₀ value that was comparable with the standard drug inhibition. In addition, this extract was exhibited remarkable cytotoxicity with less LC₅₀ value. However, this callus extract was shown very low potency in inhibiting the enzymes of acetyl cholinesterase, tyrosinase, alpha-glucosidase.

Conclusion: The study demonstrated that callus extract of Canthium parviflorum shown more potent inhibition of 5-LOX and also remarkable cytotoxicity to be further screened for in vivo anticancer and anti-inflammatory activity.
