A plant genus in the ANACARDIACEAE family known for the Pistachio nuts and for gum Mastic.
Flammable, amorphous, vegetable products of secretion or disintegration, usually formed in special cavities of plants. They are generally insoluble in water and soluble in alcohol, carbon tetrachloride, ether, or volatile oils. They are fusible and have a conchoidal fracture. They are the oxidation or polymerization products of the terpenes, and are mixtures of aromatic acids and esters. Most are soft and sticky, but harden after exposure to cold. (From Grant & Hackh's Chemical Dictionary, 5th ed & Dorland, 28th ed)
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.
A widely used anti-inflammatory agent isolated from the licorice root. It is metabolized to GLYCYRRHETINIC ACID, which inhibits 11-BETA-HYDROXYSTEROID DEHYDROGENASES and other enzymes involved in the metabolism of CORTICOSTEROIDS. Therefore, glycyrrhizic acid, which is the main and sweet component of licorice, has been investigated for its ability to cause hypermineralocorticoidism with sodium retention and potassium loss, edema, increased blood pressure, as well as depression of the renin-angiotensin-aldosterone system.
Native, inorganic or fossilized organic substances having a definite chemical composition and formed by inorganic reactions. They may occur as individual crystals or may be disseminated in some other mineral or rock.

Quaternary Ammonium Compounds
The sumac plant family in the order Sapindales, subclass Rosidae, class Magnoliopsida. They are tropical and subtropical trees, shrubs, and woody vines that have resin ducts in the bark. The sap of many of the species is irritating to the skin.
A plant genus of the family MAGNOLIACEAE. The germacranolide sesquiterpene lactones costunolide, parthenolide, and costunolide diepoxide have been isolated from the leaves. Bark contains honokiol and magnolol. Parts are an ingredient of Banxia Houpo Tang.
A class of dibenzylbutane derivatives which occurs in higher plants and in fluids (bile, serum, urine, etc.) in man and other animals. These compounds, which have a potential anti-cancer role, can be synthesized in vitro by human fecal flora. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population.
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.
