EXTRACTION OF HOMOLOGOUS COMPOUNDS OF CURCUMINOID ISOLATED FROM TEMULAWAK (Curcuma xanthorriza Roxb.) PLANT

Abstract

In the herbal pharmacopeia Indonesia, curcumin is used as a marker compound in the temulawak extract. In this study, we analyzed the contents and profiles of curcuminoid constituent in temulawak extracts from three centers for the development of medicinal plants in Central Java, Indonesia; i.e Semarang Regency, Semarang City, and Karanganyar Regency. The results showed that the extracts of temulawak have yields ranging from 8.25 -14.90% and the highest yield was obtained in the sample from one of the farmers in Semarang (B1). Meanwhile, total curcuminoid is ranging from 8.70-11.50% and the highest value belongs to sample grown in Semarang (B1 and B2, in the average levels of 11.50% and 11.30%). Variations in the composition of the curcuminoid constituent showed that curcumin is the main component in all samples. The relative contents of these compounds ranged from 68 to 76%, while the demethoxycurcuminis and bisdemethoxycurcuminis were found in the range of 23 to 29%, and from 1 to 3%, respectively.
