Jatropha Macrantha
''Jatropha macrantha'', also called the ''huanarpo macho'', is a medium size shrubby tree species in the genus ''Jatropha'' with orange red flowers. It is indigenous to Peru. It is as popular in Peru as Muira Puama is in Brazil. Catechin, catechin-7-O-β-glucopyranoside and procyanidin B3 Procyanidin B3 is a B type proanthocyanidin. Procyanidin B3 is a catechin dimer ( catechin-(4α→8)-catechin).

Johannes Müller Argoviensis
Johann Müller (9 May 1828 - 28 January 1896) was a Swiss botanist who was a specialist in lichens. He published under the name Johannes Müller Argoviensis to distinguish himself from other naturalists with similar names. Biography Müller was born into a farming family on 9 May 1828 in Teufenthal, Switzerland. He received his education at the Reinach gymnasium and then entered the Aargau industrial school, where he was passionate about botany and mathematics. Encouraged by Hans Schinz he built a herbarium of the flora of Aargau. In 1850 and 1851 he studied in Geneva and came into contact with prominent botanists Edmond Boissier and Alphonse Pyrame de Candolle (who offered him the vacant post of curator at his herbarium). In the spring of 1851 he collected in southern France with Jean Étienne Duby. The herbarium specimens from this trip were later sent to several herbaria in Europe. The following year, Müller travelled with Boissier to collect plants in the Alps of Savo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jatropha
''Jatropha'' is a genus of flowering plants in the spurge family, Euphorbiaceae. The name is derived from the Greek words ἰατρός (''iatros''), meaning "physician", and τροφή (''trophe''), meaning "nutrition", hence the common name physic nut. Another common name is nettlespurge. It contains approximately 170 species of succulent plants, shrubs and trees (some are deciduous, like ''Jatropha curcas''). Most of these are native to the Americas, with 66 species found in the Old World. Plants produce separate male and female flowers. As with many members of the family Euphorbiaceae, ''Jatropha'' contains compounds that are highly toxic. ''Jatropha'' species have traditionally been used in basketmaking, tanning and dye production. In the 2000s, one species, ''Jatropha curcas'', generated interest as an oil crop for biodiesel production and also medicinal importance when used as lamp oil; native Mexicans in the Veracruz area developed by selective breeding a ''Jatropha ...

Muira Puama
''Ptychopetalum'' is a genus of flowering plants in the family Olacaceae, native to the Amazon rainforest. Indigenous name for the genus include marapuama, muirapuama and mirantã, translating roughly to 'potency wood'. The species are shrubs or small trees growing to about in height. Its leaves are short- petioled, up to in length and in breadth light green on upper surface, dark brown on lower surface. The inflorescences consist of short axillary racemes of four to six flowers each. The root is strongly tough and fibrous, internally light brown with thin bark and broad wood, has a faint odor, and tastes slightly saline and acrid.

Catechin
Catechin is a flavan-3-ol, a type of secondary metabolite providing antioxidant roles in plants. It belongs to the subgroup of polyphenols called flavonoids. The name of the catechin chemical family derives from '' catechu'', which is the tannic juice or boiled extract of ''Mimosa catechu'' ('' Acacia catechu'' L.f). Chemistry Catechin possesses two benzene rings (called the A- and B-rings) and a dihydropyran heterocycle (the C-ring) with a hydroxyl group on carbon 3. The A-ring is similar to a resorcinol moiety while the B-ring is similar to a catechol moiety. There are two chiral centers on the molecule on carbons 2 and 3. Therefore, it has four diastereoisomers. Two of the isomers are in trans configuration and are called ''catechin'' and the other two are in cis configuration and are called ''epicatechin''. The most common catechin isomer is (+)-catechin. The other stereoisomer is (-)-catechin or ''ent''-catechin. The most common epicatechin isomer is (-)-epic ...

Catechin-7-O-glucoside
Catechin-7-''O''-glucoside is a flavan-3-ol glycoside formed from catechin. Natural occurrences Catechin-7-''O''-glucoside can be isolated from the hemolymph of the European pine sawfly (''Neodiprion sertifer''). It also occurs in relatively large quantities in cowpea (''Vigna unguiculata'') as the dominant flavan-3-ol monomer, and actually accounts for up to 70% of cowpea proanthocyanidins (tannins). It can also be produced by biotransformation of (+)-catechin by cultured cells of ''Eucalyptus perriniana''. Presence in natural traditional drugs Catechin-7-''O''-glucoside can be found in ''Paeoniae Radix'', the crude drug made from roots of the Chinese peony (''Paeonia lactiflora''), in the red knotweed ('' Bistorta macrophylla'', also known as ''Polygonum macrophyllum''), in the stem barks of the Nepali hog plum ('' Choerospondias axillaris''), in the Korean plum yew (''Cephalotaxus koreana'') and in Huanarpo Macho ('' Jatropha macrantha'').

Procyanidin B3
Procyanidin B3 is a B type proanthocyanidin. Procyanidin B3 is a catechin dimer ( catechin-(4α→8)-catechin). Natural occurrences It can be found in red wine, in barley, in beer, in peach or in ''Jatropha macrantha'', the Huanarpo Macho. Health effects It has been identified as a hair-growth stimulant. Chemical synthesis Molar equivalents of synthetic (2R,3S,4R or S)-leucocyanidin Leucocyanidin is a colorless chemical compound that is a member of the class of natural products known as leucoanthocyanidins.
