The volatile oil constituents of leaf- and fruit in Litsea glutinosa (Lour.) C.B. Robinson, identified by GC-MS analysis, was 83 and 33, respectively. The major constituents of leaf were phytol (22.42%), caryophyllene (21.48%), thujopsene (12.17%) and β-myrcene (5%); while those of the fruit oil contained lauric acid (44.84%), 3-octen-5-yne, 2,7-dimethyl (28.72%), α-cubebene (6.84%) and caryophyllene (5.04%). Litsea glutinosa (Lour.) C.B. Robinson belongs to the family Lauraceae and is a well-known evergreen species growing wild in the forest of Chittagong and Sylhet districts in Bangladesh. It is occasionally planted in most areas of the country (Ghani 2003). The plant can attain a height of 20 meters. Prior to a decade or two, L. glutinosa hardly had any commercial significance to the people but now this plant is used for some therapeutic purposes at domestic level (Saxena and Brahmam 1995). Leaves are mucilaginous and considered for antispasmodic, emollient, and poultice. The leaves are also used in diarrhoea and dysentery as well as in wounds and bruises (Ghani 2003). The leaves were reported for the treatment of the spontaneous and excessive flow of semen in young boys (Kirtikar and Basu 1981). The leaf extract also shows antibacterial and cardiovascular activities (Kar et al. 1970, Kar and Jain 1971, Chomkamon et al. 2000). The berries yield oil which is used by some tribal practitioners in the treatment of rheumatism. The extraction is difficult and the yield is very low, hence the oil is costly and less commonly used. Tannin, β-sitosterol, and actinodaphnine are reported to be the common constituents of the species; and other constituents known are : Boldine, norboldine, laurotetanine, n-methyl- laurotetanine, n-methylactinodaphnine, quercetin, sebiferine, litseferine etc. (Chatterjee and Pakrashi 1994). The essential oils of green and black fruits contained more than 40 and 30 compounds, respectively. Unripe and ripe fruit essential oils were characterized by a high proportion of (E)-β-ocimene, 70.8 and 84.1%, respectively. Predominant minor constituents of these oils were caryophyllene oxide 5 and 0.9%, respectively, β-caryophyllene (3.4 and 4.3%, respectively) and (Z)-β-ocimene, 1.8 and 2.1%, respectively (Choudhury et al. 1996, Chomkamon et al. 2000). Earlier, similar work was also carried out (Chowdhury et al. 2007). In here, the chemical composition of the leaf and fruit oils of L. glutinosa harvested from Chittagong regions of Bangladesh has been reported. The essential oil from leaves and fruits of L. glutinosa were extracted by hydrodistillation method for 4 hrs from plants grown in BCSIR Laboratories compound, Chittagong during June 2007. The essential oils from leaves and fruits of L. glutinosa were analyzed by GC-MS electron impact ionization method on GC-17A gas chromatograph (Shimadzu) coupled with a GC-MS QP 5050A Mass Spectrometer (Shimadzu); using fused silica capillary column (30 m × 2.5 mm; 0.25 µm film thickness), coated with DB-1 (J&W); injector temperature 220ºC, detector temperature 250ºC, oven temperature 60 to 250ºC (3ºC/min), column temperature initially at 100 o C (2 min) to
