Seeds, fruits and stem bark are also used in fishing by poisoning in Africa. Chemistry The methanolic extract of the fruit of ''B. madagascariensis'' contains a saponin tetraglycoside. The root bark of ''B. madagascariensis'' contains quinone methide diterpene Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicaise Auguste Desvaux
Nicaise Auguste Desvaux (28 August 1784 – 12 July 1856) was a French botanist. From 1816 he taught classes in Angers, where from 1817 to 1838 he served as director of its botanical garden. He described the botanical genera ''Neslia'', ''Mycenastrum'', ''Rostkovia'' and ''Didymoglossum''. The genus '' Desvauxia'' is named in his honor.

Methyl Paraben
Methylparaben, also methyl paraben, one of the parabens, is a preservative with the chemical formula CH3(C6H4(OH)COO). It is the methyl ester of ''p''-hydroxybenzoic acid. Natural occurrences Methylparaben serves as a pheromone for a variety of insects and is a component of queen mandibular pheromone. It is a pheromone in wolves produced during estrus associated with the behavior of alpha male wolves preventing other males from mounting females in heat. Uses Methylparaben is an anti-fungal agent often used in a variety of cosmetics and personal-care products. It is also used as a food preservative and has the E number E218. Methylparaben is commonly used as a fungicide in ''Drosophila'' food media at 0.1%. To ''Drosophila'', methylparaben is toxic at higher concentrations, has an estrogenic effect (mimicking estrogen in rats and having anti-androgenic activity), and slows the growth rate in the larval and pupal stages at 0.2%. Safety There is controversy about whether m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medicarpin
Medicarpin is a pterocarpan, a derivative of isoflavonoids. Natural occurrences Medicarpin is found in ''Medicago truncatula'' and ''Swartzia madagascariensis''. It can also be found in ''Maackia amurensis'' cell cultures. The root nodule formation by ''Sinorhizobium meliloti ''Ensifer meliloti'' (formerly ''Rhizobium meliloti'' and ''Sinorhizobium meliloti'') are an aerobic, Gram-negative, and diazotrophic species of bacteria. ''S. meliloti'' are motile and possess a cluster of peritrichous flagella. ''S. meliloti'' ...'' is apparently dependent on the flavonoids pathway. Metabolism Pterocarpin synthase has 3 substrates : medicarpin, NADP+ and H2O, and 3 products : vestitone, NADPH and H+. References Pterocarpans {{aromatic-stub ...
