Active Principles Determination by GC/MS in Delonix elata and Clerodendrum phlomidis

The present work was carried out to analyse the active constituents present in the ethanolic extract of Delonix elata (L.)  Gamble (Family:Caesalpiniaceae) and Clerodendrum phlomidis.L, (Family:Verbenaceae) by using gas chromatography-mass spectrometry (GC-MS). Thirty two compounds were identified in ethanolic extract of Delonix elata and twenty three compounds were identified in ethanolic extract of Clerodendrum phlomidis. The prevailing compound in Delonix elata was identified as Hexadecenoic acid, Z-11-(22.37%) and the prevailing compound in Clerodendrum phlomidis was identified as n-Hexadecanoic acid (28.7%). The identity and quantity of the measured active principles was correlated with the therapeutic effects of the studied herbs.
