Abstract
The aim of the presentwork is to investigate the active components present in the leaf of Delonix elata and Clerodendrum phlomidis. The plant leaf was collected and extracted with ethanol continuously for 24 hours in soxhlet apparatus,the phytochemical screening tests was conducted in ethanol extract, The crude ethanol extract indicates tannins, phenolic compounds, flavonoid and terpenes. Based on preliminary phytochemical screening tests the ethanol extract was subjected column chromatography with different solvent fractions. Hence, one compoundwas isolated from ethanol extract of Delonix elata and another one compound was isolated from ethanol extract of Clerodendrum phlomidis.The compound 1 was eluted with benzene: Chloroform 90:10 v/v and compound 2 were eluted with ethyl acetate: methanol 80:20 v/v. The structures of both isolated compounds were characterized by using FT-IR, NMR and Mass spectrophotometric methods. Thus, the compound 1 was characterized as 5,7-dihydroxy-2-(3-hydroxy phenyl)chroman-4-one (C16H14O6) from Delonix elataand compound 2 was characterized as 3,5b,8,8,11a-pentamethyl-2-(prop-l-en-2-yl)icosahydro-l-H-cyclopenta[a]chrysene-9-ol(C30H50O2) from Clerodendrum phlomidis Therefore, further biological investigations need to be carried out isolated compounds present in this plants.
