National Center for Biotechnology InformationU. The level of induction was expressed as echindoorus induction factor, i. Cupples and Miller Maron and Ames Free radicals and antioxidants in normal physiological functions and human disease.

Introduction In recent years, there has been a widespread increase in the use of medicinal plants or natural products because of their potentially beneficial effect on human health. Petioles 2 – 3 x longer than the blade, membraneously alate on the base, thin macgophyllus densely pilose under the blade.

In contrast, the origin of G: This ethyl acetate fraction is expected to contain aglycone flavonoids such as quercetin and lutheolin, and phenylpropanoids Zhang et al. Figure 3 shows the inhibitory effects of catalase, dipyridyl and thiourea on the genotoxicity of the extract in the inductest assay.

We used E medium Vogel and Bonner, solidified with 1. Comparative mutagenic effect of structurally similar flavonoids quercetin and taxifolin on tester strains Salmonella typhimurium TA and Escherichia coli WP2 uvrA. A fold increase in the number of spontaneous revertants was observed after treatment of E. Since reactive oxygen species may be implicated in aging process and in degenerative diseases, we used antioxidant compounds as catalase, thiourea and dipyridyl in the lysogenic induction test.


Genotoxicity was assessed using the inductest Moreau et al.

Support Center Support Center. It is best to spray any leaves that are out of the water to prevent them from drying out.

This ecchinodorus suggests that hydrogen peroxide present in, or generated by, compounds in the extract may have a role in the resulting genotoxicity. In many respects, the spectrum of mutations generated by the extract resembled that induced by ROS attack of guanine targets McBride et al.

Vidal1, Adriana M. Echinophyllins C-F, new nitrogen-containing clerodane diterpenoids from Echinodorus macrophyllus. These oxygen species are potent oxidants of lipids, proteins and nucleic acids, and may be related to the genotoxicity of several substances present in human foods Ames and Gold, In the case of the mut Y strain, the specific increase in G: The reason why no discussion is allowed here is this page is too general.

Analysis of sequences from 82 mutants showed base substitutions to be the most prominent mutational event in 70 cases, with 63 of these being G: Echinodorus macrophyllus Scientific classification Kingdom: Other macropjyllus such as diterpenoids have also been isolated from E.

Role of hydroxyl radicals in Escherichia coli killing induced by hydrogen peroxide.

This finding suggested that GC sites are targeted by components present in the extract. The results obtained indicate that the extract has marked genotoxic and mutagenic effects that are clearly associated with structural alterations in purine targets. G transversions was attributed to the formation of unidentified damage generated by H 2 O 2. Relation between intake of flavonoids and risk for coronary heart disease in male health professionals. Echinodlrus We thank J.


Mutagenic activity was expressed as the number of revertants per 10 8 cells. Archived copy as title CS1: A transversions in the lacI gene of catalase-defective Escherichia coli. The results represent the average of at least three experiments. In the smaller macrophullus it will often quickly form emerse leaves, which prefer moist conditions and don’t like being dried out by being too near lamps etc.

Free Radicals in Biology and Medicine. It is best to house these in an open top aquarium as the leaves will extend above the water surface and even flower stalks may be produced if the conditions are correct.

Stylar beak usually straight, approximately 0. Further studies are needed to evaluate the carcinogenicity of this extract in order to adequately assess the risks for human health. Stem upright, about twice as long as the leaves, cylindrical, between the whorls triangular, pubescent under whorls as well as petioles.

G transversions in the supF gene of E. Implication of hydrogen peroxide in the mutagenicity of coffee. However, we cannot eliminate the possibility that other types of damage, as yet uncharacterized in terms of their mutagenic potential, can give rise to G: Views Read Edit View history.
