Garcinia Hanburyi
''Garcinia hanburyi'' is a plant species in the genus ''Garcinia'', native to Indochina; it is one of the gamboge producing trees. Cytotoxic xanthonoid A xanthonoid is a chemical natural phenolic compound formed from the xanthone backbone. Many members of the Clusiaceae contain xanthonoids. Xanthonoid biosynthesis in cell cultures of '' Hypericum androsaemum'' involves the presence of a benzoph ...s ( gambogin, morellin dimethyl acetal, isomoreollin B, moreollic acid, gambogenic acid, gambogenin, isogambogenin, desoxygambogenin, gambogenin dimethyl acetal, gambogellic acid, gambogic acid, isomorellin, morellic acid, desoxymorellin, hanburin) and isomorellinol can be isolated from the dry latex of ''G. hanburyi''.

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified ...

Plants Described In 1875
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abil ...

Gambogic Acid
Gambogic acid is a xanthonoid that is derived from the brownish or orange resin from ''Garcinia hanburyi''. ''Garcinia hanburyi'' is a small to medium-sized evergreen tree (up to approximately 15 m in height) with smooth grey bark. It is native to Cambodia, southern Vietnam, and Thailand and has been successfully introduced in Singapore. Original uses Gambogic acid is the principal pigment of gambooge resin which, in addition to early traditional medicinal uses in Southeast Asia, is also a sought after dye due to the bright orange color it imparts to cloth. According to traditional Chinese medical documentation, gamboge was described as poisonous and acidic and possessed the ability to detoxify, kill parasites, and stop bleeding as a hemostatic agent. Gambogic acid has also been used in various food preparations in Asian cultures. Research Some pharmacological research on gambogic acid has been conducted ''in vitro'' and in laboratory animals, but there are no proven clin ...
