A group of XANTHENES that contain a 9-keto OXYGEN.

A plant genus of the family CLUSIACEAE. Members contain XANTHONES.

A plant genus of the family CLUSIACEAE. It is the source of the mangosteen fruit.

A plant genus of the family CLUSIACEAE. Members contain costatolide, calanolides and 4-phenylfuranocoumarins (FUROCOUMARINS).

The mangosteen plant family (sometimes classified as Guttiferae; also known as Hypericaceae) of the order THEALES, subclass Dilleniidae, class Magnoliopsida. It includes trees and shrubs with resinous, sticky sap, usually with broad-ended, oblong, leathery leaves with a strong, central vein, flowers with many stamens.

The outer layer of the woody parts of plants.

A plant genus of the family MORACEAE. Puag-haad extract, from A. lakoocha, contains STILBENES and related 4-substituted RESORCINOLS.

A plant genus of the family GENTIANACEAE. It is a source of swertiapuniside and IRIDOID GLYCOSIDES.

A plant family of the order Polygalales, subclass Rosidae, class Magnoliopsida.

Compounds with three aromatic rings in linear arrangement with a SULFUR in the center ring.

A plant genus of the family MORACEAE. Members contain maclurin, antifungal chalcones, and other compounds.

Attachment of isoprenoids (TERPENES) to other compounds, especially PROTEINS and FLAVONOIDS.

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.

Compounds with three aromatic rings in linear arrangement with an OXYGEN in the center ring.

Genus of perennial plants in the family CLUSIACEAE (sometimes classified as Hypericaceae). Herbal and homeopathic preparations are used for depression, neuralgias, and a variety of other conditions. Hypericum contains flavonoids; GLYCOSIDES; mucilage, TANNINS; volatile oils (OILS, ESSENTIAL), hypericin and hyperforin.

Compounds based on acridone, which have three linear rings, with the center ring containing a ring nitrogen and a keto oxygen opposite to each other. Many of them are naturally occurring alkaloids.

Liquids that are suitable for drinking. (From Merriam Webster Collegiate Dictionary, 10th ed)

The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.

Parts of plants that usually grow vertically upwards towards the light and support the leaves, buds, and reproductive structures. (From Concise Dictionary of Biology, 1990)

Spectrophotometry in the infrared region, usually for the purpose of chemical analysis through measurement of absorption spectra associated with rotational and vibrational energy levels of molecules. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.

A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry.

Plants whose roots, leaves, seeds, bark, or other constituent parts possess therapeutic, tonic, purgative, curative or other pharmacologic attributes, when administered to man or animals.

A post-translational modification of proteins by the attachment of an isoprenoid to the C-terminal cysteine residue. The isoprenoids used, farnesyl diphosphate or geranylgeranyl diphosphate, are derived from the same biochemical pathway that produces cholesterol.
