The use of enantiomers as additional markers for taxonomic characterization of aromatic plants may be very helpful. The differences in the enantiomeric distribution of trans- and cis- sabinene hydrates in two Origanum species enable the species to be distinguished in spite of their similar essential oil compositions. A further study on the natural variation of the enantiomeric composition within a wild population may be carried out in order to examine the stability in a taxon (including the possible presence of chemotypes). The enantiomeric ratio of essential oil components is a reliable parameter for assessing quality because it may be indicative of adulteration, contamination, aging, shelf life, technological process and the botanical source of a specific chiral compound. ... [Pg.157]

Occurs in essential oils. It is synthesized by esterification of racemic menthol. Its odor is crisper and less fruity than that of (—)-menthyl acetate. It is used for essential oil compositions and occasionally in household perfumery. [Pg.71]

The essential oils from Melaleuca alternifolia (Myrtaceae) are recommended for many medicinal and cosmetic purposes. More than 100 varieties of Melaleuca are known, having considerable differences in their essential oil composition (Fig. 17.10). In order to standardise the essential oil quality, minimum and maximum conditions are given by DAC (Deutscher Arzneimittel-Codex) and ISO 4730 (1996). [Pg.392]

EFFECT OF y-IRRADIATION IN VOLATILE OIL COMPOSITION Currently, y-irradiation is used for the decontamination of spices but its effect on essential oil composition is controversial and contradictory in cardamom (Ljubica, 1983 Klaus and Wilhelm, 1990 Maija et al, 1990). [Pg.51]

Gil et al. (2002) made a study of the essential oil composition of coriander fruits in plants growing in environments differing in soil conditions and weediness level. The variation in the oil composition was related to the relative proportion of the constituents and not to the presence/absence of a particular component. Location, fertilization and weediness also affected the chemical profile. The European landrace showed a more stable concentration of the major components than the Argentinean landrace. [Pg.198]

The composition of the volatile oil, which determines the odour and flavour characters, has been of particular interest to chemists. Ajowan oil is composed of phenols, terpenes and p-cymene. The essential oil contains more than 27 compounds, of which thymol (61%) is the major one, the others being paracymene (15.6%), y-terpinene (11.9%), (3-pinene (4-5%), dipen-tene (4-6%), camphene and myrcene. The essential oil composition of ajowan seed is given in Table 16.3. [Pg.314]

The essential oil composition and antimicrobial activity of Osmitopsis asteriscoides (Berg) Less, a medicinal plant used in traditional preparations in South Africa has been investigated [125]. Three different antimicrobial methods were comparatively evaluated against Candida albicans. Staphylococcus aureus and Pseudomonas aeruginosa The two major essential oil components, camphor. Fig. (1) and 1,8-cineole, Fig. (2) were investigated, indieating the positive antimicrobial efficacy of 1,8-cineole, Fig. (2), independently and in combination with camphor, Fig. (1). [Pg.466]

The same team, Sedlakova et al. (2003 a), has investigated the application of Supercritical Fluid Extraction for the essential oil determination in small samples gathered during breeding as an alternative method. The results were used as a one of the criteria during breeding. Classical way of the essential oil determination does not allow this option. Table 6 shows the essential oil content in Czech varieties and different essential oil composition of some European caraway resources is mentioned in table 7. [Pg.11]
