Comparative Evaluation of the Chemical Composition of Essential Oil from Twig, Leaf and Root of Clerodendrum inerme (L.) Gaertn
This study was designed to comparative evaluate the chemical composition of the essential oil from twig, leaf and root parts of Clerodendrum inerme(L.) Gaertn. GC-MS analyses of the oils revealed the presence of 8, 8 and 6 compounds in the essential oils obtained by hydrodistillation from different parts, respectively. Higher amounts of esters were found to compose a major chemotype in diverse parts of the plant. Dibutyl phthalate was the main component of all the essential oils attaining in average 34.22%, 59.28% and 44.27% and the other kind of esters accounted for 38.30%, 17.28% and 10.89% in the twig, leaf and root parts, respectively. In addition, some pharmaceutical components such as stigmasterol, linoleic acid and ferruginol were discovered. The study offers theoretic basis for utilization of the traditional folk herb C. inerme.
