Eugenia Eugenol

To add to the cost further, many of these compounds are rather sensitive to temperature and would decompose before vaporizing. For example, oil of cloves (from Eugenia caryophyllata) is rich in the phenol eugenol (V), which has a boiling point of 250 °C). We cannot extract the oils via a conventional distillation apparatus.

Clove Oil Eugenia caryophyllus) The best source in the world for eugenol. No matter where it s grown the contents are the same. No matter what part of the plant is used the eugenol content is the same. The three major clove oils of commerce are the bud (that thing on your spice shelf), the leaf and the stem oils. Each one is 80-90% eugenol. T able XVI will show you what I mean [41 ]. [Pg.129]

Eugenia ccayopyllata that is known to be the natural source of eugenol - phenolic compound that might be an inhibitor of chain radical reactions. Different samples of caryopl ene could differ in the content of the phenolic microimpurity (eugenol) and, therefore, posses different activity. All these facts have lead us to the suggestion that the epoxidation process in 02/IBA/CoNaY system has chain radical nature, and negligible impurities can dramatically influence on the reaction rate.

Materials. Trans-stilbene (Fluka AG) and (+)-a-pinene (Aldrich Chemical Company) were used as received C -stilbene and perisobutyric acid (PIBAC) were prepared as described in [19], (-)-Caryophyllene (>99%) and eugenol (95%) were isolated from the oil of Eugenia caryopyllata by vacuum rectification. (+)-3-Carene (95%) and dipentene [( )-limonene, 95%] were prepared by rectification of the Pinus sylvestris turpentine. [Pg.342]

Oil of cloves (from Eugenia caryophyllata) is rich in eugenol (4-allyl-2- methoxy-phenol). Caryophyllene is present in small amounts, along with other terpenes. Eugenol (bp 250°C) is a phenol, or an aromatic hydroxy compound. [Pg.122]
