Limonene, the chief component of orange oil, is widely used as a fragrance and flavoring, as well as a cleaning solvent. Limonene, a naturally occurring hydrocarbon, is a cyclic monoterpene, a class of natural products biosynthesized by the assembly of isoprene units into various structures. Many terpenes are responsible for the odors of plants like eucalyptus, pine, mint, lavender, rose, and others. Organic chemists use terpenes and other natural products as chiral starting materials for complex chemical syntheses or as inspirations for pharmaceuticals. Some natural products are attractive synthetic targets because of interesting or unusual structural features or medicinal applications.
Introduction Eugenol is an essential oil with a formula of C10H12O2 and a member of the phenylpropanoid family. It is mainly found and isolated from cloves or bay leaves and presents as a colorless or pale yellow oily compound. Essential oils and extracts of various species of plants, herbs, and spices constitute very potent natural biologically active agents (1). Many of these compounds are volatile and are able to undergo steam distillation in order to isolate the oil. Eugenol has a boiling point of approximately 248° C, but can be isolated from cloves at a lower temperature by performing a co-distillation with water.
"A Brief History of Sugar." A Brief History. 11 Oct 2008 <http://www.irish- sugar.ie/noframes/nf-pages/nf-hist/nf-hist.htm#productn> Sugar cane is a member of the grass family. The sugar cane has hollow stalks filled with a sweet juice or sap from which sugar can be extracted and can grow to 15 feet tall. It grows best in very warm climates and is ready to harvest after 10 to 20 months.
Salvinorin A induces an intense, short lived hallucinogenic experience qualitatively distinct from that induced by the classical hallucinogens lysergic acid diethylamide, psilocybin, and mescaline (Chavkin, 2004). Salvia is sold as seeds, plant cuttings, whole plants, fresh and dried extract-enhanced leaves of various strengths, and liquid extracts that contain salvinorin A. It is sold online with the help of online botanical companies and drugs promotional sites, advertising salvia as the legal substitute to other hallucinogenic producing plants like mescaline. These products are also sold at local shops including head shops, tobacco shops, and gas stations (Salvia divinorum, 2006). Salvinorin A and Salvia
may be steeped in hot water to make Oswego Tea. This is a strong tasting member of the mint family. Flavor like oregano. Used as a carminative, abortifacient, cold remedy, sedative, analgesic, hemostat, for coughs, emetic, to induce sweating, treat the flu, a stimulant, pulmonary aid, relieve congestion and diaphoretic byNative Americans. Edible flower, best used as a tea.
This initially results in a crude form of the herb called hypericum extract. Hypericum extract is thought to work in a similar way to antidepressant medicines, by affecting levels of neurotransmitters such as serotonin in the brain (however, the exact mechanism of action is not known). Drug… Herbal Interactions: Taking St. John's wort along with alprazolam (Xanax) might decrease the effectiveness of alprazolam (Xanax). Taking St. John's wort along with aminolevulinic acid might increase the chances of sunburn, blistering or rashes on areas of skin exposed to sunlight. Taking St. John's wort along with birth control pills might decrease the effectiveness of birth control pills.
Avocado an introduction The tree from which the commercial avocado fruit (technically a berry due to the fact it develops from a single ovary and has the seed embedded in the fruit), come from the avocado tree Persea americana Mill which originates from Central America. The avocado is a nutritious fruit high in lipids particularly mono unsaturated which may help lower levels of cholesterol. Avocados are sources of fibre and fairly high levels of protein. It is a good source of Vitamins A, B3, B5, C and E and of the mineral potassium. For a more detailed breakdown of avocados see appendix 1.
They grow to about three feet tall with long thin light green leaves that have a sharp apex (point) at the end. Numerous drooping bell shaped flowers are found on a Yucca plant with each one holding a hardened capsule full of seeds; these are dispersed by the wind. Wind dispersal is not the only way for the Yucca to reproduce; they also have a unique rhizomatous
The fruit bodies are edible when young, when the interior is white and firm and before it has turned into a powdery brown mass of spores. Laboratory tests have shown that extracts of the fruit bodies can inhibit the growth of several bacteria that are pathogenic to humans.
