Abstract/ Executive Summary:

Essential oil of fresh matured leaves of Lantana camara L. growing in Bangladesh were analyzed by GC-MS technique. Sixty two compounds were identified in the oil. The major constituents identified include caryophyllene (13.57%), α-caryophyllene (11.76%), germacrene D (10.88%), isocaryo-phyllene (9.59%), γ- muurolene (6.85%) and γ-elemene (5.65%).

Keywords: Lantana camara, Essential oil, Caryophyllene

Location: Chittagong

Start Date: 00-09-2006

End Date: 00-09-2006

Program Area: Development of Host and Medicinal Plants

Commodity: Tree

Objectives:

To determine the chemical composition of leaf essential oil of Lantana camara L.

Methodology:

The leaves of L. camara were collected from the wild sources of Chittagong during September 2006 and the oils were extracted by hydro distillation method for 4 hrs using Clevenger apparatus. The oil obtained was dried over anhydrous sodium sulphate. The essential oil from leaves of L. camara was analyzed by GC-MS electron impact ionization (EI) method on GC-17A gas chromatograph (Shimadzu) coupled to a GC-MS QP 5050A Mass Spectrometer (Shimadzu); fused silica capillary column (30m × 2.5mm; 0.25 µm film thickness), coated with DB-1 (J&W); column temperature 100ºC (2 min) to 250^oC at the rate of 3^oC/min; carrier gas, helium at constant pressure of 90 Kpa. Acquisition parameters full scan; scan range 40-350 amu. The compounds were identified by comparing with the NIST library data.

Achievement/Findings:

GC-MS analysis resulted in the identification of a total of 62 constituents from the leaf oil of L. camara. Analysis of the oil showed that the oil was a complex mixture of numerous compounds; many of which were present in trace amounts. The identified compounds accounted for more than 95% of the total oils.
