Sesquiterpenes, Guaiane: SESQUITERPENES cyclized into two adjoining rings, one being 7-carbons and the other is 5-carbons.SesquiterpenesWikstroemia: A plant genus of the family THYMELAEACEAE. Members contain daphnoretin and wikstroelides and daphnane-type DITERPENES.Sesquiterpenes, Germacrane: SESQUITERPENES cyclized to one 10-carbon ring.Saussurea: A plant genus of the family ASTERACEAE, order Asterales, subclass Asteridae. It is a source of costus root oil and should not be confused with the genus COSTUS.Sesquiterpenes, Eudesmane: SESQUITERPENES cyclized into two adjoining cyclohexane rings but with a different configuration from the ARTEMISININS.Celastraceae: A plant family of the order Celastrales, subclass Rosidae, class Magnoliopsida.Zingiberaceae: A plant family of the order Zingiberales, subclass Zingiberidae, class Liliopsida. It includes plants which have both flavoring and medicinal properties such as GINGER; turmeric (CURCUMA), and cardamom (ELETTARIA).Oils, Volatile: Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.Asteraceae: A large plant family of the order Asterales, subclass Asteridae, class Magnoliopsida. The family is also known as Compositae. Flower petals are joined near the base and stamens alternate with the corolla lobes. The common name of "daisy" refers to several genera of this family including Aster; CHRYSANTHEMUM; RUDBECKIA; TANACETUM.Illicium: A plant genus of the family Illiciaceae, order Illiciales, subclass Magnoliidae, class Magnoliopsida. They have evergreen, aromatic leaves and bisexual flowers. The female portion of the flower consists of 7 to 15 carpels.Euonymus: A plant genus of the family CELASTRACEAE.Monoterpenes: Compounds with a core of 10 carbons generally formed via the mevalonate pathway from the combination of 3,3-dimethylallyl pyrophosphate and isopentenyl pyrophosphate. They are cyclized and oxidized in a variety of ways. Due to the low molecular weight many of them exist in the form of essential oils (OILS, VOLATILE).Thymelaeaceae: A plant family of the order Myrtales, subclass Rosidae, class Magnoliopsida. They are mainly trees and shrubs. Many members contain mucilage and COUMARINS.Drimys: A plant genus of the family WINTERACEAE. They have leathery, elliptic-shaped leaves; red-tinged shoots; and jasmine-scented, cream-colored, 8- to 12-petaled, 2.5-centimeter (1-inch) flowers in clusters.Pulicaria: A plant genus of the family ASTERACEAE. Members contain pulicanadienes and other cytotoxic SESQUITERPENES.Terpenes: A class of compounds composed of repeating 5-carbon units of HEMITERPENES.Rhizome: Root-like underground horizontal stem of plants that produces shoots above and roots below. Distinguished from true roots which don't have buds and nodes. Similar to true roots in being underground and thickened by storage deposits.Valerian: A plant genus of the family VALERIANACEAE, order Dipsacales, subclass Asteridae, class Magnoliopsida. It is best known for the sedative use and valepotriate content of the roots. It is sometimes called Garden Heliotrope but is unrelated to true Heliotrope (HELIOTROPIUM).Lindera: A plant genus in the LAURACEAE family. Lindera benzoin is a source of a balsamic resin called benzoin which is up to 1/3 BENZOIC ACID. This should not be confused with the chemical BENZOIN or the plant STYRAX BENZOIDES.Inula: A plant genus of the family ASTERACEAE. Members contain INULIN, alantol, helenin, alantic acid, and acrid resin.Magnoliaceae: A plant family of the order Magnoliales, subclass Magnoliidae, class Magnoliopsida. They are trees and shrubs having an elongated conelike floral axis with fragrant flowers that have six tepals (sepals and petals that are not distinctly different) and many spirally arranged stamens.Eremophila Plant: A plant genus of the family MYOPORACEAE. Members have been used in FOLK MEDICINE.Plant Extracts: Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.Chrysanthemum: A plant genus of the family ASTERACEAE. The common names of daisy or marguerite are easily confused with other plants. Some species in this genus have been reclassified to TANACETUM.
