Essential oil from the rhizomes of two types of Curcuma longa, yellow and red originated in Bangladesh was analyzed by GC-MS. 54 compounds have been identified from the yellow type of which the major compounds are ar-tumerone (27.78%), tumerone (17.16%), culone (13.82%), 2-carene (4.78%), zingiberene (4.37%) and β-sesquiphellandrene (5.57%). The red type contained 39 compounds with carvacrol (21.14%), citral (13.91%), methyleugenol (7.31%), geraniol (6.99%), menthol (5.11%) and caryophyllene oxide (4.14%) as major constituents. Key words: Curcuma longa, GC-MS, Ar-tumerone, Carvacrol, Tumerone, Citral. DOI: 10.3329/bjsir.v43i2.970  Bangladesh J. Sci. Ind. Res. 43(2), 259-266, 2008

Turmeric essential oil is known to have antioxidant activity. Various in vitro antioxidantactivity assays has been carried out. Related to this research, it tries to examine the antioxidantpotential of turmeric essential oil and see the composition that is responsible for antioxidant activitycombine with chemometrics. The research method used was a narrative review of 60 articlesobtained from several databases. The review conducted on profiling essential oil compounds thatidentified using GC-MS and evaluation of the antioxidant activity of turmeric essential oil with themost commonly used method including scavenging radical 2,2 diphenyl-1-picrylhydrazyl (DPPH)and 2,2-azinobis (3-ethylbenzothiazoline-6 sulfonic acid (ABTS). Analysis methods used forgrouping various multivariate data subjects and determaining the relationship between thevariables were Principal Component Analysis (PCA) and Cluster Analysis (CA). According to thereview, turmeric essential oils are proven to have potential antioxidant activity and have variationsin chemical contents. PCA was success for grouping subjects with various correlated variables,determining variables wich the most influential and correlation between variables. CA method canbe used to group samples without requiring mutually correlated variables.

Turmeric (Curcuma longa L.) is a spice plant grown in the tropics that contains both an essential oil and an oleoresin. The essential oil is important as a flavouring and has pharmaceutical properties, while the oleoresin is bright yellow in colour and has medicinal properties. The essential oil has traditionally been extracted by hydrodistillation/steam distillation with the total extract being extracted by solvent extraction and more recently by supercritical fluid extraction (SFE). The objective of the work described in this paper was to investigate the possibility of extracting the essential oil using sub-critical fluid extraction and to compare it with hydrodistillation. The experiments using hydrodistillation showed that unpeeled fresh turmeric was the preferred raw material, giving an oil yield of ≈6% dry weight basis, which is similar to that reported in the literature. The experimental programme on the extraction of the oil from dried unpeeled turmeric was carried out over a temperature range from 25 to 30 °C and pressures from 65 to 71 bar. Yields were generally higher than hydrodistillation (up to ≈9% dry weight basis) as were the compositions of the extracted oils. The preferred operating conditions were determined to be 25 °C temperature and 65 bar pressure. Curcumin, the major component of the oleoresin, was not found in the oil, thereby demonstrating that the sub-critical extract is a pure essential oil. It is suggested that consideration be given to evaluating an SFE process whereby the essential oil is initially fully extracted under sub-critical fluid extraction conditions, after which the oleoresin is extracted separately by raising the pressure to ≈250 bar.

Turmeric rhizomes are commonly used in the culinary, pharmaceutical, herbal medicine, and beverage industries. On the contrary, turmeric leaves are underutilized.  The aims of this study were to extract the essential oil from turmeric leaves, characterize the chemical composition of the oil, and determine its antifungal activities against aflatoxin-producing fungi. Steam distillation was used to extract the essential oil from turmeric leaves. The properties of the oil were identified using GC-MS. Antimicrobial activities against Aspergillus flavus and Aspergillus parasiticus were determined. Spores of the fungi were inoculated into potato dextrose agar plates supplemented with various quantities of turmeric leaves essential oil and incubated at 30°C for 7 days. The oil's primary constituents were α-phelandrene(46.70 %), followed by α-terpinolene (17.39 %), 1,8-cineole (8.78 %), benzene (4.24 %), and 2-β pinene (3.64 %). At low (<1%) concentrations, the oil delayed mycelia formation and at high concentrations it significantly inhibit fungal growth (at 1%) and completely inhibit colony formation (at 2%) Additionally, the result show that turmeric leaves oil can inhibited fungus growth at the lowest concentration (0.25 %) when compared to the control over a seven-day incubation period.

In the present study, we have evaluated the antitumour and anticarcinogenic activity of turmeric essential oil in vivo. Turmeric essential oil was found to have significant in vitro cytotoxic activity against Dalton’s lymphoma ascites cells (DLA) and Ehrlich ascites carcinoma (EAC) cancer cell lines. Concentration needed for 50% cytotoxicity (IC50) was 8 μg for DLA cells and 18 μg to EAC cell lines. Oral administration of turmeric essential oil was found to significantly increase the life span (56.25%) of Dalton’s Lymphoma Ascites (DLA) induced ascites tumour bearing mice as well as significantly reduced (P<0.001) the solid tumours. 3-Methyl cholanthrene induced sarcoma development was also delayed and there was significant increase in the life span of mice after oral administration of turmeric essential oil. Moreover, turmeric essential oil significantly (P<0.001) inhibited phenobarbitone induced cytochrome p450 enzyme activity in rats.
