Barbigerone is one of a few pyranoisoflavones among several groups of isoflavones. It was first isolated from the seed of a leguminous plant Tephrosia barbigera; hence the name "barbigerone". [1] Members of the genus Millettia are now known to be rich in barbigerone, including M. dielsiena, [2] M. ferruginea, [3] M. usaramensis, [4] and M. pachycarpa . [5] It has also been isolated from the medicinal plant Sarcolobus globosus . [6] Barbigerone from S. globosus is validated to have significant antioxidant property. [7] Barbigerone exhibits profound antiplasmodial activity against the malarial parasite Plasmodium falciparum . [8] It is also demonstrated that it has anti-cancer potential as it causes apoptosis of murine lung-cancer cells. [9]
Isoflavones are substituted derivatives of isoflavone, a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the bean family, Fabaceae (Leguminosae).
Tephrosin is rotenoid. It is a natural fish poison found in the leaves and seeds of Tephrosia purpurea and T. vogelii.
Daidzin is a natural organic compound in the class of phytochemicals known as isoflavones. Daidzin can be found in Japanese plant kudzu and from soybean leaves.
Ononin is an isoflavone glycoside, the 7-O-β-D-glucopyranoside of formononetin, which in turn is the 4'-O-methoxy derivative of the parent isoflavone daidzein.
Apigeninidin is a chemical compound belonging to the 3-deoxyanthocyanidins and that can be found in the Patagonian plant Ephedra frustillata and in the soybean. Apigeninidin is one of the principal pigments found in sorghum. Extremely high level of apigeninidin (49 mg/g) has been documented in sorghum leaf sheath. Like all anthocyanidins it exists in a variety of tautomers depending on pH and hydration, several of these bare the distinctive pyrylium core.
Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols.
Irigenin is an O-methylated isoflavone, a type of flavonoid. It can be isolated from the rhizomes of the leopard lily, and Iris kemaonensis.
The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups. O-methylation has an effect on the solubility of flavonoids.
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid.
Ergosterol peroxide (5α,8α-epidioxy-22E-ergosta-6,22-dien-3β-ol) is a steroid derivative. It has been isolated from a variety of fungi, yeast, lichens and sponges, and has been reported to exhibit immunosuppressive, anti-inflammatory, antiviral, trypanocidal and antitumor activities in vitro.
Retusin is an O-methylated isoflavone, a type of flavonoid. It can be found in Fabaceae species like Dipteryx odorata, in Dalbergia retusa and in Millettia nitida. It can also be found in Maackia amurensis cell cultures.
Calycosin is an O-methylated isoflavone. It can be isolated from Astragalus membranaceus Bge. var. mongholicus and Trifolium pratense L..
Eupalitin is an O-methylated flavonol. It can be found in Ipomopsis aggregata.
Millettia pachycarpa is a perennial climbing shrub belonging to the genus Millettia. It is one of the most well known among ~150 species of Millettia, as it is widely used in traditional practices, such as for poisoning fish, agricultural pesticide, blood tonic, and treatments of cancer and infertility. The bark fiber is used for making strong ropes.
Sarcolobus globosus is a twining shrub native to tropical regions of Asia including India, China, Thailand, Malaysia, Myanmar-Burma, the Philippines and Indonesia.
Rotenoids are naturally occurring substances containing a cis-fused tetrahydrochromeno[3,4-b]chromene nucleus. Many have insecticidal activity, such as the prototypical member of the family, rotenone. Rotenoids are related to the isoflavones.
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes which can be formed by coupling of the B ring to the 4-one position.
Astringin is a stilbenoid, the 3-β-D-glucoside of piceatannol. It can be found in the bark of Picea sitchensis or Picea abies.
7-O-Methylluteone is a prenylated isoflavone. It can be found in the bark of Erythrina burttii.
Isorhapontin is a stilbenoid. It is the glucoside of isorhapontigenin. It can be found in mycorrhizal and non-mycorrhizal roots of Norway spruces, in the bark of Picea sitchensis or in white spruce.
