Abstract

The terpenoids have been prized for their human uses over two thousand years. Plants have the potentiality to produce a diverse nature of secondary metabolites that have versatile biological functions. Most of the phytochemicals are useful to us. About 140 different sesquiterpenes have been isolated from the genus Curcuma, and they can be classified into ten distinctly different structural types. However, most of these compounds fall into one of the three major categories, bisabolane, germacrane, or guaiane types. These plants used commonly in food technology as well as pharmaceutical industries. The key constituents of exhibit a wide range of bioactive potentialities like anticandiadal, antibacterial and antimetastatic activities. Curcuma caesia is endemic to the North East Asia, where an infusion of the rhizomatous parts of the plant is used in folk medicine as an antidiabetic, anticancerous agent. Consequently, the reveal of medicinal properties of the secondary metabolites of this plant have been the subject of an ongoing study. Now a day, solving the mystery of bioactive potentiality of natural product is one of the largest thrust areas of research in life science. Nature possesses all the disease curing agents (bioactive phytochemicals) that we need to reveal for our healthy life style. The use of Black Turmeric, Turmeric etc. in Indian tradition is found from ancient time, even when people do not exactly know the actual bioactive potentiality or mode of action of phytochemicals present in the extract of Black Turmeric and Turmeric.
