Flavonoid Flavonoids are most commonly known for their antioxidant activity. However, it is now known that the health benefits they provide against cancer and heart disease are the result of other mechanisms. Flavonoids are also commonly referred to as bioflavonoids in the media the terms are largely equivalent and interchangeable, for most flavonoids are biological in origin. H H H 출처 : wikipedia
Lignan The lignans are a group of chemical compounds found in plants, particularly in flax seed. Lignans are one of the major classes of phytoestrogens, which are estrogen-like chemicals and also act as antioxidants. The other classes of phytoestrogens are the isoflavones. Plant lignans are polyphenolic substances derived from phenylalanine via dimerization of substituted cinnamic alcohols to a dibenzylbutane skeleton 2 2 R 2 R 1 CH 3 CH 3 CH 3 H shizandrin: R 1=R2=CH3 gomisin A: --CH 2-- 오미자 (Schizandra chinensis ) CH 3 출처 : wikipedia
Coumarin Coumarin is a chemical compound (benzopyrone); a toxin found in many plants, notably in high concentration in the tonka bean, woodruff, and bison grass. It has a sweet scent, readily recognised as the scent of newly-mown hay, and has been used in perfumes since 1882. It has clinical medical value as the precursor for several anticoagulants, notably warfarin.

탄닌 (tannin) Tannins are astringent, bitter plant polyphenols that either bind and precipitate proteins. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of red wine, strong tea, or an unripened fruit. The term tannin refers to the use of tannins in tanning animal hides into leather; however, the term is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with proteins and other macromolecules. Tannins have molecular weights ranging from 500 to over 3,000. Tannins are incompatible with gelatin, heavy metals, iron, lime water, metallic salts, strong oxidizing agents and zinc sulfate. Medical potential; Tannins have shown potential antiviral, antibacterial, and antiparasitic effects. In the past few years tannins have also been studied for their potential effects against cancer through different mechanisms. Tannins, including gallo and ellagic acid (epigallitannins), are inhibitors of HIV replication. 출처 : wikipedia
식물색소 엽록소외에과피, 잎등에함유, Cartenoid, flavonoid, benzoquinone, anthraquinone 등 Quinone Benzoquinone, or quinone is one of the two isomers of cyclohexadienedione. Anthraquinone (9,10-dioxoanthracene) is an aromatic organic compound. It is a derivative of anthracene. It has the appearance of yellow or light gray to gray-green solid crystalline powder. Anthraquinones naturally occur in some plants (e.g. aloe, senna, rhubarb, and cascara), fungi, lichens, and insects, where they serve as a basic skeleton for their pigments. Natural anthraquinone derivatives tend to have laxative effects. 출처 : wikipedia

Saponin Saponins are a class of chemical compounds, one of many secondary metabolites found in natural sources, with saponins found in particular abundance in various plant species. Specifically, they are amphipathic glycosides by the soap-like foaming they produce when shaken in aqueous solutions, and structurally by their being composed of one or more hydrophilic glycoside moieties combined with a lipophilic triterpene derivative 출처 : 한국민족문화대백과 출처 : 네이버캐스트
