Profiling polyisoprenoids in kopasanda (Chromolaena odorata) stem barks and roots

Abstract

Kopasanda (Chromolaena odorata (L.) R.M. Rob, Asteraceae) distributed in tropical and subtropical countries, including Indonesia. The kopasanda leaves contain several major compounds, such as tannins, phenols, flavonoids, saponins, and steroids. However, polyisoprenoids have no previously reported from this plant. This study aimed to determine the distribution of polyisoprenoid compounds in the bark and roots of the kopasanda plant. Total lipid on the kopasanda bark and roots was 61 and 48 mg/g dry weight. In comparison, the value of polyisoprenoid ranges from 11.8 and 27.3 mg/g dry weight. Results showed that polyisoprenoid compounds found in the roots were polyprenols and dolichols, regarded as type-II of polyisoprenoids. In contrast, in the bark of kopasanda, polyisoprenoid compounds a member of are a type I. Because dolichol dominated on bark, no plyprenols were detected. The present study confirmed the occurrence of polyisoprenoids in kopasanda roots and barks.
