Essential oils indigenous, from

Eugenol occurs in essential oils and is a major constituent of carnation, cinnamon, and clove oils. The substance is primarily is obtained from the clove oil isolated from trees indigenous to the Molluca Islands, and which are also cultivated in other parts of Indonesia, Zanzibar, Madagascar, and Ceylon. Clove is rich in volatile oil (16-19% by weight), which can be obtained by distillation. 

Producers normally rely on only a few source oils indigenous to their geographic area or that can be imported economically. Soybean is the primary oil used in the United States while very little palm is consumed and none is produced. Canada s major oil is canola (low-erucic-acid rapeseed). Malaysia, Indonesia, and Central America are the largest producers and users of palm oil. Eastern Europe, like Canada, relies on low-erucic-acid rapeseed (LEAR), sunflower, and soybean oils. It is apparent from Table 3 that it is virtually impossible to formulate products with controlled melting and crystalline properties using only one of these oils. Even in areas where conditions and economics justify a variety of types, modification methods other than blending are essential to adequately control rheologic properties. 

Indigenous essential oils from Madagascar are important for income generation. Madagascar has been a significant exporter of essential oils, thus the country has tremendous potential to further expand the essential oil industry. However, the misirrformation of their essential oils and the lack of standards to define product identity and qrrahty are among some of the problems and obstacles that affect the industry (7-2). Typical examples of this lack of information are the ravintsara and raverrsara essential oils that have been traditionally misidentified in the marketplace 3-6). 

The essential oil of C. camphora (199 individual samples) were obtained from leaves of cultivated trees harvested from two geographieal areas, the central highlands and the eastern eoast. The essential oil of R. aromatica (130 individual samples 115 sabinene - hmonene types, 10 methyleugenol types, and 5 methylchavicol types were manrrally collected from leaves of wild indigenous... 

C15H20O2, Mr 232.32, colorless crystals, mp. 82 °C, bp. 275 °C, [a] 3 +197° (CHCI3), almost insoluble in water, soluble in alcohol and ether. The name of this tricyclic sesquiterpene lactone is derived from the Asteraceae ]nula helenium originally indigenous to Central Asia. H. was isolated for the first time from the essential oil of the roots (Inula oil). H. is also an older synonym for helenalin as well as the name for a metabolite from Penicillium funiculosum (ribonucleoprotein). Because of its a-methylene-y-lactone structure H. is a contact allergen.

Yu-Jn oil is a tenn applied to an essential oil which is obtained from the so-called Oil Tt, indigenous to southern Formosa, and which is closely related to camphor oil in its properties. Its failure, however, to yield camphor in the course of production is the diief feature differing from camphor oil, and evidently indicates the I eascm why the natives call the mother-tree, lH-chhiu or Oil Tree Similarly, the term Tu-boku or Yu-bun-b6ku, as frequently applied by the Japanese to the tree, which yields only a little camphm, and a large quantity of oil, su ests the inconspicuously small percentage of camphor obtainable. 

American pennyroyid oil is distilled from a herb indigenous to North America, Hedeoma pulegoides. The oil is principally distilled in North Carolina, Ohio, and Tennessee. The dried leaves yield about 3 per cent.,. and the leaves and stalks together about 1 5 per cent, of essential oil. 

The principal essential oil of this group is that of Artemisia Absinthium, oil of wormwood, or oil of absinthe. It is distilled from the herb, a plant indigenous to the mountainous regions of Northern Africa, Southern Europe, and Northern Asia, and cultivated to a considerable extent in Nor America, especially in the States of Michigan and Indiana, and in Wayne County, New York State. 

The berries of Heeria Paniculosa, a plant indigenous to Zuzuland known to the natives as Isifeku, yield from 4 5 to 6 per cent, of essential oil, which has been examined by Juritz. A sample examined in the Imperial Institute Laboratories had the following characters —...
