Colquhoun and Schumacher [98] have shown that y-linolcnic acid and eicosapentaenoic acid, which inhibit Walker tumor growth in vivo, decreased proliferation and apoptotic index in these cells. Development of apoptosis was characterized by the enhancement of the formation of reactive oxygen species and products of lipid peroxidation and was accompanied by a decrease in the activities of mitochondrial complexes I, III, and IV, and the release of cytochrome c and caspase 3-like activation of DNA fragmentation. Earlier, a similar apoptotic mechanism of antitumor activity has been shown for the flavonoid quercetin [99], Kamp et al. [100] suggested that the asbestos-induced apoptosis in alveolar epithelial cells was mediated by iron-derived oxygen species, although authors did not hypothesize about the nature of these species (hydroxyl radicals, hydrogen peroxide, or iron complexes ). 

To ensure coverage of a broad spectrum of journals containing both original and review articles, bibliography databases, such as CAB abstracts, BIDS ISI and Embase, Medline and Current Contents Agriculture and Food Citation index, were searched. Terms used for all database searches were kept simple to limit the risk of missing any original publications (Table 4.5). Initially, each flavonoid subclass was entered and then cross-searched with the... 

Cl, 0.37-0.71) for flavanones, 0.62 (95% Cl, 0.43-0.89) for flavonols, and 0.56 (95% Cl, 0.40-0.78) for total flavonoids. No significant association emerged for other classes of flavonoids. The ORs were consistent across strata of age, sex, education, body mass index, tobacco, and alcohol. After allowance for vegetable and fruit consumption, the inverse relations with total flavonoids and flavanones remained significant, whereas that with flavonols became nonsignificant. None of the associations was significant after further allowance for... 

If it can be shown that flavonoids do play a role in reducing the risk of cataract, they will only account for a proportion of the total effect, as many other plant constituents, such as vitamins and minerals, have also been shown to be effective. It should also be remembered that cataract is a multifactorial disease, with diet but one of many possible risk factors among, for example, poverty, UV radiation, smoking, diabetes, body mass index, age, sex, and hypertension [9], all of which may interact in a highly complex manner to facilitate development of disease.

Phytochemistry Aboveground plant parts contain 0.4 % total alkaloids, from which spherophysine, spherosine, and saponins with hemolytic index of 1 40 have been isolated (Sokolov and Zamotaev 1989). Isoflavans, lignans, coumarins, flavonoids, and sterols have also been isolated from the plant (Ma et al. 2002b, 2003,2004a, b Hou et al. 2005).

Morin is 2-(2,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-l-benzopyran-4-one (also, 2, 3,4, 5,7-pentahydroxyflavone) it is a flavonoid (flavonol) compound and is the principal component of so-called old fustic , a dye derived from Madura tinctoria (L.) Steudel (Moraceae formerly Chlorophora tinctoria (L.) Gaud.) (Schweppe, 1992 Merck Index, 1996). Use of old fustic in pigments has been mentioned by Harley (1982). Morin is hsted in the Colour Index as Cl 75660/Natural YeUow 8 and 11.

Chemically 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4H-l-benzopyran-4-one (or 3,3, 4, 5-tetrahydroxy-7-methoxy-flavone or 7-methylquercetm). A flavonoid dyestuff principally derived from the berries of various plants belonging to the Rham-naceae, though it may also be synthesised (Merck Index, 1996). It is listed in the Colour Index as Cl 75690/Natural Yellow 13. See rhamnus.
