Abstract/ Executive Summary:

Seven components have been identified including caryophyllene oxide (24.14%), caryophyllene (22.19%), limonene (21.79%) and myrcene (9.02%), as significantly dominating compounds of essential oil from inflorescences of Spilanthes calva DC. from Bangladesh investigated by gas chromatography mass spectrometry.

Keywords: Spilanthes calva, Essential oil, GC-MS, Caryophyllene oxide

Location: BCSIR Laboratory, Chittagong during October 2007

Program Area: Development of Host and Medicinal Plants

Commodity: Medicinal Plants

Objectives:

The present study is about GC-MS analysis of essential oil components of S. calva inflorescence.

Methodology:

S. calva plants were collected from campus of BCSIR Laboratory, Chittagong during October 2007. Samples of inflorescences were harvested from healthy, well-grown plants. Freshly harvested inflorescences (250 gm.) were grounded in a blender. The grounded inflorescences were subjected to hydrodistillation using a modified Clevengertype glass apparatus for 4 h for isolation of oils. The oil sample was stored at 0°C in airtight containers after drying them over anhydrous sodium sulfate and filtered before subjected to GC-MS analysis. The essential oil from inflorescences of S. calva 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 (30 m × 2.5 mm; 0.25 mm film thickness), coated with DB-5 ms (J&W); column temperature 100^oC (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. Compound identification was done by comparing the NIST (National Institute of Standards and Technology-Chemistry web book) library data of the peaks with those reported in literature. Percentage composition was computed from GC peak areas on DB-5 ms column without applying correction factors.

Achievement/Findings:

On the basis of findings of the present investigation it may be said that S. calva, growing widely in Bangladesh, may be utilized as a source for the isolation of natural caryophyllene oxide and caryophyllene respectively.
