“…Seven diff erent chemo types are known, depending on the main components of the essential oil: thymol, carvacrol, linalool, geraniol, thujanol-4, terpineol and 1,8-cineole. [20,21] Since there is a correlation between the fragrance and composition of the essential oil, the odour could help users to choose the necessary desired chemotype for their intended use. [22] Other Thymus spp., such as T. caespititius, T. lotocephalus and T. villosus, [23][24][25] also reveal an accentuated chemi cal variability.…”

Aromatic plants and spices are used throughout the world for fl avouring food and beverages, as well as for food supplements, novel foods and as a source of essential oils and aromatic extracts. The non-availability or inadequacy of standards for checking and assuring the quality of aromatic plants and spices is one of the main problems that arise for industry when using such raw materials. As many aromatic plants are harvested from the wild, standardization to assure their quality is important for their safe and eff ective utilization in food and beverage industries. On the other hand, there are numerous parameters that infl uence the chemical composition of plants, which play an important role in the fi nal quality of the product and possibly in any risk arising to the consumer. Also, from a safety point of view, aromatic plants and spices should be free of undeclared contaminants and adulterants, such as toxic botanicals, pathogenic microorganisms and excessive levels of microbial toxins, pesticides or fumigation agents. We focus on these aspects and examine ways to assure their appropriate utilization from the quality and safety standpoint. The regulatory situation of medicinal and aromatic plants (MAPs) is very complicated; several diff erences in standards and regulations between countries can be found, a situation that can result in more health risks arising for consumers. To clarify some of the existing problems, the major regulations of the USA and the European Union (EU) and the borderlines between food supplements and medicines and other international standards, are briefl y described and discussed.

“…Siahkal and Mazandaran 2 populations were placed in the second group that contain high amounts of linalool (6.5-8.98%) and α-terpineol (10.8-11.08%), and also amount of para -cymene (2.48-3.9%) and borneol (3-3.16%). Previously, different types of chemical has been reported for this species of thyme (Torras et al,2007;Sefidkon et al, 2005;Lozine and Venskutonis, 2005;Blanquer et al,1998). Results of the simple correlation between the essential oil components and yield are shown in Table 3.…”

ABSTRACT. Thymus species are well known as medicinal plants because of their biological and pharmacological properties. Thymus kotschyanus seeds (10 populations) were collected from various provinces of Iran and transferred into a new uniform environment. This study was carried out at Badiei Research Station (Qom Province, Iran) in 2008, under field conditions. The experiment was carried out as a randomized complete block design with three replicates.

“…En la literatura se citan hasta 7 quimiotipos de esta especie, dependiendo en cada caso del componente más abundante: timol, carvacrol, geraniol, linalol, α-terpineol, γ-terpineol (Torras et al, 2007;Rota et al, 2008) y el quimiotipo 1,8 cineol, endé-mico de la Península Ibérica (Guillén y Manzanos, 1998).…”

Vahl., Lavandula x intermedia Emeric ex Loisel., Lavandula latifolia Medik., Lavandula angustifolia Mill. and Thymus vulgaris L. are presented. The essential oils have been analysed by Gas Chromatography Mass Spectrometry and 61 compounds were identified, 23 of which represented more than 1% of the essential oil. The 1,8 cineole (16-23%) appeared as the main compound of Salvia sp. essential oils. The high content of α-thujone was characteristic in S. officinalis oil. Remarkable concentrations of linalool (30-33%), camphor (5-17%) and linalyl acetate (9-28%) were detected in Lavandula sp. oils while carvacrol (21.6%) and p-cimene (23.7%) were the most abundant compounds in T. vulgaris oil. Biological characterization was based on their bioplaguicide activity. The essential oils studied had strong antifeedant effects against Leptinotarsa decemlineata Say, Spodoptera littoralis Boisd., Myzus persicae Sulzer and Rhopalosiphum padi L., phytotoxic activity against Lactuca sativa L. and Lolium perenne L. and also exhibited high antifungal activity against Fusarium sp. Oils from T. vulgaris and L. latifolia showed the highest levels of bioactivity against all target species. These results provide an added-value to the essential oils of aromatic plants of agro-industrial interest for its potential use in the development of natural agrochemicals. KEY-WORDS: Bioplaguicide activity -Essential oilsLavandula -Natural agrochemicals -Salvia -Thymus INTRODUCCIÓNEl cultivo de plantas aromáticas representa una importante actividad agraria en algunas zonas de España y, particularmente, en las comarcas castellano-manchegas de la Alcarria (Cuenca y Guadalajara), Serranía Alta (Cuenca) y Señorío de MolinaAlto Tajo (Guadalajara) donde se concentra el 50% de la producción nacional de lavandas (MARM, 2010).El principal producto comercial obtenido de estas especies vegetales es su aceite esencial (AE). Más del 90% de la producción de AE se utiliza como materia prima en la industria de la cosmética (perfumes y productos para la piel y el cabello), in- RESUMEN Perfil químico y biológico de aceites esenciales de plantas aromáticas de interés agro-industrial en CastillaLa Mancha (España)En este trabajo se presenta el estudio químico y biológico de los aceites esenciales de Salvia officinalis L., Salvia lavandulifolia Vahl., Lavandula x intermedia Emeric ex Loisel., Lavandula latifolia Medik., Lavandula angustifolia Mill. y Thymus vulgaris L. El estudio químico por cromatografía de gases acoplada a espectrometría de masas de los aceites esenciales permitió la identificación de 61 compuestos, de los cuales 23 presentaron un porcentaje mayor o igual al 1 %. Los aceites esenciales de Salvia sp. se caracterizaron por presentar un alto contenido de 1,8 cineol (16-23%) y, en el caso específico de S. officinalis, una elevada proporción de α-tuyona (15.7%). En Lavandula sp., los compuestos mayoritarios del aceite fueron linalol (30-33%), alcanfor (5-17%) y acetato de linalilo (9-28%); mientras que en T. vulgaris lo fueron carvacrol (21.6%) y p-cimeno ...
