Abstract

The present study was undertaken to formulate and evaluate the anti-inflammatory, anti-oxidant and anti-angiogenic activities of nanoemulsion of MemecylaeneMemecylaene was isolated from the leaves of Memecylon malabaricum by using various chromatographic methods. An oil-in-water (O/W) nanoemulsion of Memecylaene was formulated by sonication method using sunflower oil (oil phase), Tween 80 (Surfactant) and Ethanol (co-surfactant). The prepared nanoemulsion was characterized for its droplet size, poly dispersity index and zeta potential. Stability studies were performed and the nanoemulsions were subjected to different biological activities. The formulated nanoemulsion had a particle size range of 52.02 nm to 59.47 nm and zeta potential of -1.27 mV. The enhanced activity of Memecylaene, encapsulated in O/W emulsions is evidenced by the inhibition of phospholipase (PLA2) enzyme and H+, K+ -ATPase and thus showing anti-inflammatory and anti-secretagogues effects. The in vitro anti-oxidant activity was evaluated by DPPH radical and Nitric oxide radical scavenging activity. Further, the inhibition of the growth of neo vessels formation in the in-vivo model system of chick chorioallantoic membrane (CAM) assay, which is angiogenesis dependent, was also observed. The above findings would help in understanding the putative potential of Memecylaene-loaded nanoemulsion as a therapeutic agent.
