Several studies have shown that quercetin causes macdophyllus substitutions and frameshift mutations in Ames strains Bjeldanes and Chang, ; Hatcher and Bryan, ; Makena et al. The latter noted that the increase in mutation frequency after treatment with H 2 O 2 correlated closely with the increase in 8-oxoguanine formation.

Catalase Sigma Chemical Co. In the smaller aquarium it will often quickly form emerse leaves, which prefer moist conditions and don’t like being dried out by being too near lamps etc.

Mutagenic activity of quercetin and related compounds. Factors affecting the mutagenic activity of quercetin for Salmonella typhimurium TA Click here to close this box. Archived from the original on Role of hydroxyl radicals in Escherichia coli killing induced by hydrogen peroxide.

An aqueous extract of E.

Echinodorus macrophyllus

Hydrogen peroxide and coffee induce G: Stem upright, about twice as long as the leaves, cylindrical, between the whorls triangular, pubescent under whorls as well as petioles. Many plants may be effective phytomedicines but need to be exhaustively investigated to detect any toxic side effects.

The Escherichia coli strains used in this work are listed in Table 1 and the S. Mutagenic and genotoxic effects of mate Ilex paraguariensis in prokaryotic organisms. Retrieved from ” https: The results represent the average of at least three experiments. The aglycones lutheolin and quercetin may be responsible for this activity and could be potentially carcinogenic in uncontrolled human consumption.

Viability was determined based on the mean values of survival inactivation data not shown. This damage is unrelated to cellular lethality in E. Support Center Support Center.

Echinodorus macrophyllus (Aquatic plants)

Although this is a rhizome plant, division of the rhizome is not the only way this plant can be propagated. To confirm the results obtained with the Ames test, experiments were done using tryptophan auxotrophic E. The samples obtained with each partitioning were subsequently screened for genotoxicity in the Inductest. The genetic toxicology of metal compounds: G transversion was the most frequent 28 casesfollowed by 26 cases of G: We used E medium Vogel and Bonner, solidified with 1.


After pre-incubation, the mixtures were poured onto E medium plates containing tryptophan 0. 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.

Revised methods for the Salmonella mutagenicity test. There was a strong trend towards base substitutions and frameshifts at purine sites macropuyllus the mutations induced by the extract in Escherichia coli CC and CC strains and Salmonella typhimurium test strains fold increase in histidine revertants in TA98 strain.

Echinodorus macrophyllus (Kunth) Micheli, – Taxonomy

Archived copy as title CS1: Analysis mqcrophyllus sequences from 82 mutants showed base substitutions to be the most prominent mutational event in 70 cases, with 63 of these being G: Echinodolides A and B, new cembrane diterpenoids with an eight-membered lactine ring from the leaves of Echinodorus macrophyllus. RAP Working Papers The plant produces a rhizome which a mass is extracted. Mutational specificity of oxidative DNA damage.
