A group of FLAVONOLS based on kaempferol. They are derived from naringenin and can be hydroxylated to QUERCETIN or reduced to leucopelargonidin.
A flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin.
An oxyacid of chlorine (HClO) containing monovalent chlorine that acts as an oxidizing or reducing agent.
A plant genus of the family TROPAEOLACEAE. The common nasturtium is a plant that grows 2.4-3.6 m (8-12 feet) tall and has funnel-shaped flowers that are commonly yellow-orange with red spots or stripes and have a long spur that contains sweet nectar. Some species in this genus are called watercress which is also a common name for RORIPPA and NASTURTIUM.
Naturally occurring or synthetic substances that inhibit or retard the oxidation of a substance to which it is added. They counteract the harmful and damaging effects of oxidation in animal tissues.
A flavonol glycoside found in many plants, including BUCKWHEAT; TOBACCO; FORSYTHIA; HYDRANGEA; VIOLA, etc. It has been used therapeutically to decrease capillary fragility.
A plant family of the order Santalales, subclass Rosidae, class Magnoliopsida. They are parasites that form connections (haustoria) to their hosts to obtain water and nutrients. The one-seeded fruit may be surrounded by a brightly colored nut-like structure.
A group of 3-hydroxy-4-keto-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.
A group of phenyl benzopyrans named for having structures like FLAVONES.
Diseases of the muscles and their associated ligaments and other connective tissue and of the bones and cartilage viewed collectively.
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.
A 20-carbon dibenz(de,kl)anthracene that can be viewed as a naphthalene fused to a phenalene or as dinaphthalene. It is used as fluorescent lipid probe in the cytochemistry of membranes and is a polycyclic hydrocarbon pollutant in soil and water. Derivatives may be carcinogenic.
A trinitrobenzene derivative with antispasmodic properties that is used primarily as a laboratory reagent.
Drugs intended to prevent damage to the brain or spinal cord from ischemia, stroke, convulsions, or trauma. Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.
The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.
Individual's rights to obtain and use information collected or generated by others.
A quantitative measure of the frequency on average with which articles in a journal have been cited in a given period of time.
The period of history before 500 of the common era.
Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
A publication issued at stated, more or less regular, intervals.
A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
A plant family of the order Fagales subclass Hamamelidae, class Magnoliopsida.
An order of BIRDS comprising the waterfowl, particularly DUCKS; GEESE; swans; and screamers.
