Edgar Charles Bate-Smith
Edgar Charles Bate-Smith (1900-1989Practical Polyphenolics, Edwin Haslam, 1998, ) was an English chemist and phytochemist specialising in food chemistry. He worked in the Low Temperature Research Station in Cambridge where his main fields of research were meat and polyphenols. The discovery in 1943 by Martin and Synge of paper chromatography provided for the first time the means of surveying the phenolic constituents of plants and for their separation and identification. There was an explosion of activity in this field after 1945, none more so than that of Bate-Smith and Tony Swain (chemist), Tony Swain. In 1951, Bate-Smith developed and first described a coloration method to detect the presence of condensed tannins (also called proanthocyanidins) in plant materials. This reaction is based on heating in acidic conditions and gives rise to anthocyanidin pigments. Bate-smith recommended the use of the Forestal solvent for the isolation of leuco-anthocyanins in 1954. In 1973, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forestal
Forestal is a solvent used in chromatography, composed of acetic acid, water, and hydrochloric acid Hydrochloric acid, also known as muriatic acid, is an aqueous solution of hydrogen chloride. It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid Acid strength is the tendency of an acid, symbol ... in a 30:10:3 ratio by volume. It is useful for isolating anthocyanins in room-temperature chromatography using standard filter paper. References * * Pecket, R.C.

Commanders Of The Order Of The British Empire
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
