“…Oleic, linoleic, and palmitic acids were also present in significant amounts in the extracts. These results are within the range of FA composition reported in the literature for daphne seed oil (2). HPLC analysis of SC-CO 2 and petroleum ether extracts showed extremely high FFA content in the oil, over 50% (Table 2).…”

Laurus nobilis L., commonly known as daphne tree, is an evergreen that belongs to the Lauraceae family. Daphne trees produce grape-sized shiny purplish berries having three parts: flesh, skin, and an inner kernel (single seed). This study examines supercritical CO 2 (SC-CO 2 ) extraction of oil from daphne seeds. The oil yield of ground seeds varied from 14 to 28% depending on the method and particle size used for oil recovery. Yields were similar for both petroleum ether and SC-CO 2 extraction. The extraction yield decreased significantly with increasing particle size. The amount of extract collected increased exponentially with increasing SC-CO 2 pressure. The highest extraction yield was obtained at the highest temperature studied, 75 o C. More than 45% of the oil was lauric acid. SC-CO 2 is a viable technique to obtain high-purity L. nobilis L. seed oil, which is a potential ingredient for the cosmetic industry.Paper no. J11352 in JAOCS 83, 953-957 (November 2006). FIG. 4. Extract solubility as a function of pressure. All the experiments were carried out at 75°C. Particles with mean diameter of 0.17 mm were used for these experiments. FIG. 5. Extract solubility as a function of temperature. All the experiments were carried out at 68 MPa. Particles with 0.17 mm were used for these experiments.

“…The whole berry, flesh, skin, and kernel/seed contain 26, 38, 8, and 18% oil, respectively (1). The oil extracted from berries contains the following FA: lauric (54%), palmitic (5%), oleic (15%), and linoleic (17%) (2). Unsaponifiable components of berry oil include undecanone, α-terpinol, terpineol acetate, β-elemene, and β-sitosterol.…”

“…The dried leaves are used extensively in home cookery (Putievsky, Ravid, Snir, & Sanderovich, 1984) and the essential oil is used mainly in the flavouring industry. Laurel essential oil, also called laurel leaf oil or sweet bay essential oil, was reported to be used in the preparation of hair lotion for its antidandruff activity and for the external treatment of psoriasis (Hafizog˘lu & Reunanen, 1993). This oil is generally obtained by hydro or steam distillation.…”

Isolation of essential oil from dried and ground leaves of Laurus nobilis L. from Algeria and Tunisia were obtained with two different methods: by means of classical hydrodistillation (HD) and by using carbon dioxide in the supercritical state (SFE). The effect of extraction pressure on the yield and composition of the L. nobilis volatile oil is examined. The best extraction conditions were as follows: pressure, 9.0 MPa; temperature, 323.15 K; 4 h of extraction and carbon dioxide flow, Phi = 1.2 kg h(-1). Waxes were entrapped in the first separator set at 9.0 MPa and 263.15 K. The oil was recovered in the second separator working at 2.0 bar and 288.15 K. GC/MS analysis of the leaves' volatile oil revealed that it mainly consisted of: 1,8-cineole, linalool, alpha-terpinyl acetate, methyl eugenol and sabinene. The comparison with the hydrodistilled oil did not reveal any big difference. The collection of samples at different extraction times during supercritical extraction allowed us to monitor the change of the oil composition. On the matrice exhaust owing to a SFE at 9.0 MPa, one further extraction at 323.15 K and 24.0 MPa was performed to obtain a mixture of compounds with higher molecular weight. Finally, the antibacterial and antifungal activity of the various extracts has been assayed.

In addition, it is used by the cosmetic industry in creams, perfumes, and soaps (Hafizo glu and Reunanen, 1993).
