Glucosides
Glucosides are glycosides that contain glucose as the sugar component, often forming part of the plant's defense mechanism and can have various pharmacological effects when extracted and used medically.
Glycosides
Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)
Iridoids
A type of MONOTERPENES, derived from geraniol. They have the general form of cyclopentanopyran, but in some cases, one of the rings is broken as in the case of secoiridoid. They are different from the similarly named iridals (TRITERPENES).
Norisoprenoids
Thirteen-carbon butene cyclohexene degradation products formed by the cleavage of CAROTENOIDS. They contribute to the flavor of some FRUIT. Ionone should not be confused with the similarly named ionol.
Iridoid Glucosides
Rubiaceae
Anthocyanins
A group of FLAVONOIDS derived from FLAVONOLS, which lack the ketone oxygen at the 4-position. They are glycosylated versions of cyanidin, pelargonidin or delphinidin. The conjugated bonds result in blue, red, and purple colors in flowers of plants.
Thioglucosides
beta-Glucosidase
An exocellulase with specificity for a variety of beta-D-glycoside substrates. It catalyzes the hydrolysis of terminal non-reducing residues in beta-D-glucosides with release of GLUCOSE.
Quercetin
A flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin.
Glucosyltransferases
Amygdalin
A cyanogenic glycoside found in the seeds of Rosaceae.
Plant Extracts
Verbena
A plant genus of the family VERBENACEAE. Members contain verbenachalcone (dimeric dihydrochalcone), iridoids, and phenylethanoids.
Plant Leaves

Molecular Structure
Spectrometry, Mass, Fast Atom Bombardment
A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.

Isoflavones
3-Phenylchromones. Isomeric form of FLAVONOIDS in which the benzene group is attached to the 3 position of the benzopyran ring instead of the 2 position.

Picrates
Picrates are salts of picric acid, an explosive organic compound previously used as a yellow dye and antiseptic, which are now primarily used in chemical research and industrial applications. Please note that picrates should be handled with care due to their potential explosiveness when heated or subjected to friction.

Thioglycosides
Malva
Juniperus
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).
Caffeic Acids
Manihot
A plant genus of the family EUPHORBIACEAE that is perennial with conspicuous, almost palmate leaves like those of RICINUS but more deeply parted into five to nine lobes. It is a source of a starch after removal of the cyanogenic glucosides. The common name of Arrowroot is also used with Maranta (MARANTACEAE). The common name of yuca is also used for YUCCA.
Rhizome
Petasites
Uridine Diphosphate Glucose
A key intermediate in carbohydrate metabolism. Serves as a precursor of glycogen, can be metabolized into UDPgalactose and UDPglucuronic acid which can then be incorporated into polysaccharides as galactose and glucuronic acid. Also serves as a precursor of sucrose lipopolysaccharides, and glycosphingolipids.
Methylglycosides
Methylglycosides are glycosides with a methanol group (CH3-) replacing the hydrogen atom on the glycosidic oxygen, which can be found in various natural sources and have potential applications as sweetening agents or in pharmaceuticals.
Jasminum
A plant genus of the family OLEACEAE. Members contain secoiridoid glucosides and this is the source of oil of jasmine.
Solanum melongena
A plant species of the genus SOLANUM, family SOLANACEAE. The fruit is a large, egg-shaped berry, varying in color from dark purple to red, yellowish, or white. The leaves are large and ovate. The flowers are pendant, violet, and two inches across.
Pyrans
Nitriles
Organic compounds containing the -CN radical. The concept is distinguished from CYANIDES, which denotes inorganic salts of HYDROGEN CYANIDE.
Oleaceae
Methylglucosides
Methylglucosides are a type of sugar alcohols, specifically methylated glucose derivatives, which are used as sweetening agents, excipients, and solvents in pharmaceutical and cosmetic products due to their low toxicity and good solubility in water.
Limonins
A group of degraded TRITERPENES in which the four terminal carbons of the C17 side chain have been removed, and the remaining portion often forming C17 furans.
Triterpenes
Balanophoraceae
Liliaceae
A monocot family within the order Liliales. This family is divided by some botanists into other families such as Convallariaceae, Hyacinthaceae and Amaryllidaceae. Amaryllidaceae, which have inferior ovaries, includes CRINUM; GALANTHUS; LYCORIS; and NARCISSUS and are known for AMARYLLIDACEAE ALKALOIDS.
