Overview

From past several years the conventional methods are generally employed in plant material extraction that include Soxhlet, reflux apparatus but the method is time consuming and requires solvent in large quantity. To overcome this problem the novel extraction technique are nowadays used for the extraction of the plant material. The Microwave assisted extraction technique offers several advantages over conventional method i.e. low solvent consumption, shortened extraction time with increased purity and yield of bioactive phytoconstituents. Operculina turpethum (Convolvulaceae) found throughout India at an altitude of about 1000m and commercially cultivated in Ceylon, tropical America, Mauritius, Philippines, Australia and tropical Africa. In India it is sometimes grown in gardens as an ornamental plant. The roots/ rhizomes of the Operculina turpethum was extracted by conventional and microwave assistant extraction using various solvents pet. ether, ethyl acetate, methanol, hydroalcholic and aqueous solvents. The result indicates that the microwave extraction process gives high yield of phytoconstituent when compared with conventional methods. The extracts obtained by both the process were further evaluated for assessment of total phenolic, flavonoid and saponin content. The research findings suggest that the microwave assisted extraction techniques has remarkably increased the phenolic, flavonoid and saponin content in the extract. Furthermore, microwave irradiation method proved to be a rapid and improved system for the plant extraction.
