Nutmeg is the seed, or the ground spice derived from that seed, of several tree species of the genus Myristica; fragrant nutmeg or true nutmeg is a dark-leaved evergreen tree cultivated for two spices derived from its fruit: nutmeg, from its seed, and mace, from the seed covering. It is also a commercial source of nutmeg essential oil and nutmeg butter. Indonesia is the main producer of nutmeg and mace, and the true nutmeg tree is native to its islands.
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins.
Perfume is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of manmade mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory."
Citrus hystrix, called the kaffir lime or makrut lime, is a citrus fruit native to tropical Southeast Asia.
Myristicin is a naturally occurring compound found in common herbs and spices, such as nutmeg. It is an insecticide, and has been shown to enhance the effectiveness of other insecticides. When ingested, myristicin may produce hallucinogenic effects, and can be converted to MMDMA in controlled chemical synthesis. It interacts with many enzymes and signaling pathways in the body, and may have dose-dependent cytotoxicity in living cells.
Thymol, C10H14O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris, ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from T. vulgaris. Thymol is only slightly soluble in water at neutral pH, but it is extremely soluble in alcohols and other organic solvents. It is also soluble in strongly alkaline aqueous solutions due to deprotonation of the phenol. Its dissociation constant (pKa) is 10.59±0.10. Thymol absorbs maximum UV radiation at 274 nm.
An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are commercially cultivated to have appealing aromas, and contain several hundred aroma compounds.
Steam distillation is a separation process that consists in distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
Eugenol is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil. Eugenol has a pleasant, spicy, clove-like scent. The name is derived from Eugenia caryophyllata, the former Linnean nomenclature term for cloves. The currently accepted name is Syzygium aromaticum.
Rose oil is the essential oil extracted from the petals of various types of rose. Rose ottos are extracted through steam distillation, while rose absolutes are obtained through solvent extraction, the absolute being used more commonly in perfumery. The production technique originated in Greater Iran. Even with their high price and the advent of organic synthesis, rose oils are still perhaps the most widely used essential oil in perfumery.
Carvacrol, or cymophenol, C6H3(CH3)(OH)C3H7, is a monoterpenoid phenol. It has a characteristic pungent, warm odor of oregano.
The terpinenes are a group of isomeric hydrocarbons that are classified as monoterpenes. They each have the same molecular formula and carbon framework, but they differ in the position of carbon-carbon double bonds. α-Terpinene has been isolated from cardamom and marjoram oils, and from other natural sources. β-Terpinene has no known natural source but has been prepared from sabinene. γ-Terpinene and δ-terpinene have been isolated from a variety of plant sources. They are all colorless liquids with a turpentine-like odor.
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries.
Cannabis flower essential oil, also known as hemp essential oil, is an essential oil obtained by steam distillation from the flowers, panicles, stem, and upper leaves of the hemp plant. Hemp essential oil is distinct from hemp seed oil and hash oil: the former is a vegetable oil that is cold-pressed from the seeds of low-THC varieties of hemp, the latter is a THC-rich extract of dried female hemp flowers (marijuana) or resin (hashish).
Cryptocarya agathophylla is a member of the laurel family, Lauraceae, and originates in Madagascar.
Monodora myristica, the calabash nutmeg, is a tropical tree of the family Annonaceae or custard apple family of flowering plants. It is native to Angola, Benin, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, Ghana, Guinea-Bissau, Ivory Coast, Kenya, Liberia, Nigeria, the Republic of the Congo, Sierra Leone, Sudan, Tanzania, Togo and Uganda. In former times, its seeds were widely sold as an inexpensive nutmeg substitute. This is now less common outside its region of production. Other names of calabash nutmeg include Jamaican nutmeg, African nutmeg, ehuru, ariwo, awerewa, ehiri, airama, African orchid nutmeg, muscadier de Calabash and lubushi.
Eryngium planum, the blue eryngo or flat sea holly, is a species of flowering plant in the family Apiaceae, native to the area that includes central and southeastern Europe and central Asia. It is an herbaceous perennial thistle growing to 50 cm (20 in) with branched silvery-blue stems, and numerous small blue conical flowerheads surrounded by spiky bracts in summer.
Bergamot essential oil is a cold-pressed essential oil produced by cells inside the rind of a bergamot orange fruit. It is a common flavoring and top note in perfumes. The scent of bergamot essential oil is similar to a sweet light orange peel oil with a floral note.
In chemistry, a phenol ether (or aromatic ether) is an organic compound derived from phenol (C6H5OH), where the hydroxyl (-OH) group is substituted with an alkoxy (-OR) group. Usually phenol ethers are synthesized through the condensation of phenol and an organic alcohol; however, other known reactions regarding the synthesis of ethers can be applied to phenol ethers as well. Anisole (C6H5OCH3) is the simplest phenol ether, and is a versatile precursor for perfumes and pharmaceuticals. Vanillin and ethylvanillin are phenol ether derivatives commonly utilized in vanilla flavorings and fragrances, while diphenyl ether is commonly used as a synthetic geranium fragrance. Phenol ethers are part of the chemical structure of a variety of medications, including quinine, an antimalarial drug, and dextromethorphan, an over-the-counter cough suppressant.
