Spreng and Murraya paniculata (L.) Jack %-3 Introduction A systematic study on the medicinal and aromatic plants is being carried out in Bangladesh. Among these plants one finds Murraya koenigi (L.) Spreng and M. paniculata (L.) Jack of the Rutaceae family. Murraya koenigii (L.) Spreng is a small strong smelling perennial shrub or small tree commonly found in forests as undergrowth, cultivated in India for its aromatic leaves and for ornament. Leaves are used as a condiment in the preparation of curry powder, pickle, chutney, sausages and seasonings (Anonymous, 1962; Hiremath et al., 1998). The flavor and fragrance of leaves retain even after drying (Omankutty Amma et al., 1984). Leaves relieve nausea, indigestion, vomiting; eaten as a cure for diarrhea and dysentery (Anonymous, 1962; Ghani, 2003). Essential oil composition of leaves has been studied by various workers. The major consti- tuents responsible for the aroma and flavor have been reported as pinene, sabinene, caryophyllene, cadinol and cadinene (Anonymous, 1962; Nigam and Purohit, 1961; Prakash and Natarajan, 1974; Macleod and Pieries, 1982; Hiremath et al., 1998). Raina et al. (2002) reported four genetically divers chemotypes (1) β- pinene (70%), β-caryophyllene (6.5%) and α-pinene (5.4%), (2) α-pinene (65.7%), β-pinene (13.4%) and β- phellandrene (7.4%), (3) β-caryophyllene (53.9%), aromadendrene (10.7%) and α-selinene (6.3%), (4) β- phellandrene (30.2%), β-caryophyllene (24.2%), α- pinene (15%), (E)-β-ocimene (5%) and aromadendrene (4.5%) as major constituents from various parts of India. Walde et al. (2005) reported α-pinene (52%) and cis-β- ocimene (34%) as major constituents in Hyderabad plants. M. paniculata (L) Jack. syn. Chalcas paniculata L. Chalcas exotica (L.) Millsp. is a very variable evergreen shrubby plant with small white flowers, small oblong fruits and hard wood, planted in gardens as an ornamental in many areas of the country. Leaves are stimulant and astringent and are used in the treatment of diarrhea, dysentery and diseases of teeth and gum; useful against rheumatism, coughs and hysteria (Anonymous, 1962; Chopra et al., 1956; Ghani, 2003). The essential oils showed significant anti-inflammatory and analgesic activities (Dash et al., 2004). Sawangjaroen et al.

Spreng and M. paniculata (L.) Jack from Bangladesh was studied by gas chromatography mass spectroscopy (GC-MS). M. koenigii oil contained 39 compounds of which the major is 3-carene (54.2%) followed by caryophyllene (9.5%). Oil of M. paniculata contained 58 compounds of which the major are caryophyllene oxide (16.6%), β-caryophyllene (11.8%), spathulenol (10.2%), β-elemene (8.9%), germacrene D (6.9%) and cyclooctene, 4-methylene-6-(1-propenyli- dene) (6.4%). The compositions of both oils varied qualitatively and quantitatively. $UWLFOH�,QIR Received: 16 May 2008 Accepted: 19 May 2008 Available Online: 19 May 2008 DOI: 10.3329/bjp.v3i2.841 Cite this article: Chowdhury JU, Bhuiyan MNI, Yusuf M.
