A comparison of chemical composition of bay laurel extracts obtained by microwave extraction, supercritical fluid extraction and steam distillation was performed. Microwave extraction and steam distillation were shown to give similar essential oils. Microwave extract contains more monoterpenoid components, especially hydrocarbons. Steam distillation oil contains more sesquiterpenoid compounds, mostly oxygenated. SFE extract composition differs substantially from the ones obtained by two other methods. According to GC-MS data they contain much more sesquiterpenoid components, namely sesquiterpene lactones. This makes SFE a perspective candidate for isolation of biologically active compounds from laurel leaves. However, apart from valuable compound SFE extracts also contain substantial amounts of waxes as well as large quantities of some non-volatile component undetectable via GC-MS. In order to implement SFE into the practice of laurel processing one has to develop an approach for the fractionation of SFE extracts allowing isolating sesquiterpene lactone enriched fraction.

Series Of Experiments

The supercritical fluid extraction (SFE) of clove bud essential oil was studied using CO2 as solvent. The effect of operation conditions was analyzed in a series of experiments at temperatures between 325 and 416 K and pressures between 110 and 190 bar. The collected extracts were analyzed and the relative composition of the essential oil was determined. The optimum condition was found in a temperature of 353 K and at a pressure of 190 bar, minimizing the number of extracts to two compounds (eugenol and eugenyl acetate). The extract obtained from clove bud by using supercritical fluid extraction was compared with the essential oil obtained by steam distillation and microwave-assisted extraction by considering both quantity and quality of the product. The oil yield was higher in steam distillation and microwave oven extraction. In contrast, oil extracted by using SFE contained higher amount of eugenol and eugenyl acetate.

Schisandra chinensis (Turcz.) Baill., which is known as omija in South Korea, is mainly cultivated in East Asia. The present study aimed to investigate the chemical composition of essential oil from the omija (OMEO) fruit obtained by supercritical fluid extraction using CO2 and to confirm the antioxidant and anti-inflammatory activity of OMEO using HaCaT human keratinocyte and RAW 264.7 murine macrophages. As a result of the chemical composition analysis of OMEO using gas chromatography-mass spectrometry, a total of 41 compounds were identified. The detailed analysis results are sesquiterpenoids (16), monoterpenoids (14), ketones (4), alcohols (3), aldehydes (2), acids (1), and aromatic hydrocarbons (1). OMEO significantly reduced the increased ROS levels in HaCaT keratinocytes induced by UV-B irradiation (p < 0.05). It was confirmed that 5 compounds (α-pinene, camphene, β-myrcene, 2-nonanone, and nerolidol) present in OMEO exhibited inhibitory activity on ROS production. Furthermore, OMEO showed excellent anti-inflammatory activity in RAW 264.7 macrophages induced by lipopolysaccharide. OMEO effectively inhibited NO production (p < 0.05) by suppressing the expression of the iNOS protein. Finally, OMEO was investigated for exhibition of anti-inflammatory activity by inhibiting the activation of NF-κB pathway. Taken together, OMEO could be used as a functional food ingredient with excellent antioxidant and anti-inflammatory activity.

Main Portion

Caraway fruits contain 1&ndash;6% of essential oils consisting of about 30 compounds, from which carvone and limonene account form the main portion, about 95%. To evaluate the quality of various caraway cultivars, the amounts of essential oils and the carvone/limonene ratio were measured. The most common method of essential oil evaluation is steam distillation in accordance with Standard ČSN 58 0110, but an alternative method &ndash; supercritical fluid extraction (SFE) &ndash; was also investigated in this paper. Ground caraway fruits were extracted under different SFE conditions (pressure, temperature, use of modifiers). Released compounds (carvone and limonene) were quantified by GC. &nbsp;

The chemical composition of mentha essential oil and mentha extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC-MS. The menthol content was also determined spectrophotometrically. The predominant compounds in the essential oil and in the CO2 extract obtained at 100 bar were L-menthon and menthole but at higher pressures (from 150 to 400 bar), squalene was dominant. The equation of Naik et al. was used for modelling the mentha-supercritical CO2 system.

The extracts obtained from sweet basil (Ocimum basilicum L.) by hydrodistillation and supercritical fluid extraction (SFE) were qualitative and quantitative analyzed by GC-MS and GC-FID. Essential oil (EO) content of basil sample, determined by an official method, was 0.565% (V/w). The yields of basil obtained by SFE were from 0.719 to 1.483% (w/w), depending on the supercritical fluid (carbon dioxide) density (from 0.378 to 0.929 g mL-1). The dominant compounds detected in all investigated samples (EO obtained by hydrodistillation and different SFE extracts) were: linalool, as the major compound of basil EO (content from 10.14 to 49.79%, w/w), eugenol (from 3.74 to 9.78%) and ?-cardinene (from 3.94 to 8.07%). The quantitative results of GC-MS from peak areas and by GC-FID using external standard method involving main standards, were compared and discussed.
