ABSTRACT

180Plants are one of the most important sources of medicines. Syzygium cumini known as “jamun” in Hindi which is found in throughout India. The leaves are having promising therapeutic value with its various phyto constituents such as tannin, alkaloids, flavonoids, terpenoids, fatty acid, phenol, minerals, carbohydrates, and vitamins. All these phyto constituents are analyzed by qualitative analysis method. Betulinic acid is a naturally occurring pentacyclic triterpenoid compound. The medicinal application of betulinic acid is available for diabetes, cancer cell, and HIV. Betulinic acid shows more solubility for methanol. For extraction of betulinic acid, different extraction techniques like batch extraction and Soxhlet extraction techniques are used. The effect of various parameters like particle size, agitations speed, temperature, and solid loading is studied. To explain the extraction of biological material from plant sources different model equations are used which describes sorption isotherms of material. The experimental data of solid loading and temperature are best fitted by using second order Peleg’s model. From this model the linearized Arrhenius equation was obtained and temperature dependency was 0.567 kJ/mol. The aim of this study is to find out the best kinetic model for extraction and experimental data shows the good agreement of betulinic acid with methanol which justifies batch extraction process.
