Phytochemicals are chemicals derived from plants.In a narrower sense the terms are often used to describe the large number of secondary metabolic compounds found in plants.Many of these are known to provide protection against insect attacks and plant diseases.They also exhibit a number of protective functions for human consumers!
Flavonoids (or bioflavonoids) (from the Latin word flavus meaning yellow, their colour in nature) are a class of plant secondary metabolites.Flavonoids were referred to as Vitamin P (probably because of the effect they had on the permeability of vascular capillaries) from the mid-1930s to early 50s, but the term has since fallen out of use.more.
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C14H8O2.Anthraquinone is a general name of the chemicals which has the basic nuclear parent as shown in the picture,its 1,4,5,8 position is called alpha position;its 2,3,6,7 positions is called beta position.Several isomers are possible,each of which can be viewed as a quinone derivative.The term anthraquinone, however, almost invariably refers to one specific isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring.Anthraquinone class chemicals normally combined with glycoside and form glycosides,called anthraglycosides.The anthraquinone chemicals are commonly seen in the TCM herbs!more.
Saponins is a class of glycoside chemicals which has complicated chemical structure,derived from spirostane and other sterides shared with similar origins,majorly Oligosaccharide or Oligosaccharides of Triterpenoids,their molecular weight is considerably big.Saponins has many biological activities including eliminating phlegm, relieve cough,calm donw,antibacterial,anti-cancer,antipyretic activity.Saponins widely exist and spread in those plants monocotyledon and dicotyledon in the nature,especially most commonly existed in plant families like liliaceae family,Cargophyllaceae family,Araliaceae family,Leguminosae family,Polygalaceae family,Campanulaceae family,Dioscoreaceae family etc.Many important TCM herbs contains triterpenoids,such like Platycodon grandiflorum,radix bupleuri,polygala root,ginseng,licorice.more.
