- Abstract
The volatile oil of the leaves and barks of Calycopteris floribunda was examined by gas chromatography/mass spectrometry (GC/MS). Fifty-two constituents were identified in leaves oil; caryophyllene oxide (13.79%), n-hexadecanoic acid (11.91%) and β-caryophyllene (10.45%) were found to be the major components. Ten constituents identified represent about 99.98% of the total barks oil; among these, n-hexadecanoic acid (59.18%), linolic acid (12.70%) and butyl octyl phthalate (8.21%) were the major constituents. The antibacterial and antifungal activities of both oils were tested against eight microorganisms by disk diffusion method in vitro. The oils exhibited strong antimicrobial activity, and were proved to be more active against the tested bacteria than the fungi. The leaves oil exhibited broader antibacterial spectrum and higher inhibition activity against mostly microbe than the barks oil.
