ABSTRACT

Objective: ?-Caryophyllene (BCP) is a natural sesquiterpene existing in the essential oil of many plants, has exhibited a wide range of biological activities. However, its volatility and poor water-solubility limit its application in pharmaceutical field. ?-Cyclodextrin (?-CD) has intrinsic ability to form specific inclusion complexes with different drugs to enhance their stability, solubility and bioavailability. The aim of this study is to investigate on the formulation and evaluation of sesquiterpenoid nanoparticles. Methods: Sesquiterpenoid nanoparticles were prepared by solvent evaporation method using Eudragit RL100 and Eudragit RS100 alone and combinations by rotary flash evaporator. These nanoparticles were evaluated for drug entrapement effeciency, invitro release,SEM and zeta potential measurement. Conclusion: In FX formulation the concentration (drug 50mg, Eudragit RL100 15mg, Eudragit RS100 30mg) showed the highest entrapement efficiency 98%. In the FX formulation the percentage of drug release was 99.45% in 24 hours. The optimized formulation was analysed by scanning electrone microscope and stability studies and zetapotential. The sesquiterpenoids nanoparticles exhibited nanometer size ranging from 41.61nm to 77.95nm. and also zeta potential charge.
