Abstract Numerous members of the Anthemideae tribe are important as cut flowers and ornamental crops, as well as being medicinal and aromatic plants, many of which produce essential oils used in folk and modern medicine and in the cosmetics and pharmaceutical industry.

Essential oils generally have a broad spectrum of bioactivity, owing to the presence of several active ingredients that work through various modes of action. Due to their mode of extraction, mostly by distillation from aromatic plants, they contain a variety of volatile molecules such as terpenes, phenol-derived aromatic and aliphatic components.

The large genus Artemisia L. Artemisia species, widespread throughout the world, are one of the most popular plants in Chinese traditional preparations and are frequently used for the treatment of diseases such as malaria, hepatitis, cancer, inflammation and infections by fungi, bacteria and viruses. Extensive studies of the chemical components of Artemisia have led to the identification of many compounds as well as essentials oils.

Plants have been used as drugs by humans since thousands of years ago. Artemisia L. It belongs to the important family Compositae Asteraceae , one of the most numerous plant groupings, which comprises about 1, genera and over 20, species. Within this family, Artemisia is included in the tribe Anthemideae and comprises over species, which are mainly found in Asia, Europe and North America [ 1 ]. A large number of members of the Anthemideae tribe are important as cut flowers and ornamental crops, as well as medical and aromatic plants, many of which produce essential oils used in folk and modern medicine, and in the cosmetics and pharmaceutical industry [ 2 ].

Essential oils generally have a broad spectrum of bioactivity, owing to the presence of several active ingredients or secondary metabolites, which work through various modes of action. Secondary metabolism in a plant not only plays a role in its survival by producing attractants for pollinators, but it also acts as a chemical defence against predators and disease. According to the mode of extraction used, mostly distillation from the aromatic plants, essential oils contain a variety of volatile molecules such as terpenes, phenolic-derived aromatic and aliphatic components.

The large genus Artemisia from the tribe Anthemideae comprises important medicinal plants which are currently the subject of phytochemical attention because of their biological and chemical diversity, and essential oil production.

It possesses insecticidal, antibacterial, anticholesterolemic, antipyretic, antiseptic, cholagogue, diuretic, purgative and vasodilatatory activity, and is also used for the treatment of gall bladder inflammation, hepatitis and jaundice [ 4 ].

Artemisia spicigera C. This species serves as a critical habitat and food resource for many animals and invertebrates [ 13 ]. Artemisia vulgaris L. It has also been suggested to have other medicinal activities such as anti-inflammatory, antispasmodic, carminative and anthelmintic properties, and has been used in the treatment of painful menstruation dysmenorrhoea and in the induction of labour or miscarriage [ 23 ].

Taxonomy The genus Artemisia is characterized by a wide range of morphological and phytochemical variability, which is associated with different geographical origins of the samples. The genus displays a huge ecological plasticity, with species occurring from sea level to high mountains and from arid zones to wetlands. Additionally, polyploidy is notably common and reported cytotypes differ in external morphology, anatomy, fertility and phytochemical cytogenetically [ 24 ].

Chemical Composition of Essential Oils from the Artemisia Genus Essential oils are volatile, natural, complex compounds characterized by a strong odour and are formed by aromatic plants as secondary metabolites. They are usually obtained by steam or hydro-distillation, although there are several methods for extracting them. These may include the use of liquid carbon dioxide and microwaves, but mainly involve low or high pressure distillation employing boiling water or hot steam.

In nature, essential oils play an important role in the protection of plants as antibacterials, antivirals, antifungals, insecticides and also against herbivores by reducing their appetite for such plants. They also may attract some insects, thereby favouring the dispersion of pollens and seeds, or repel other undesirable insects. Chemically, essential oils are very complex natural mixtures which can contain about 20—60 components at quite different concentrations.

Generally, these major components determine the biological properties of the essential oil. The components include two groups with different biosynthetical origins: the main group is composed of terpenes, and the other of aromatic and aliphatic constituents, all characterized by their low molecular weight. The strong and aromatic smell of some species of Artemisia genus is due mainly to high concentrations of volatile terpenes, constituents of their essential oils, especially in leaves and flowers.

The chemical composition of essential oils from the Artemisia genus has been extensively studied in several species from around the world. Many studies have shown that Artemisia species display significant intraspecific variations in the terpene constituents of their essential oils.

In some cases, the variation in the volatile components of these plants may occur during plant ontogeny or growth at different altitudes. The quality and yield of essential oils from Artemisia species is influenced by the harvesting season, fertilizer and pH of soils, the choice and stage of drying conditions, the geographic location, chemotype or subspecies, choice of plant part or genotype, or extraction method.

Reported constituents of Artemisia species are outlined in Table 1.
