The mutagenic potencies of plant extracts containing quercetin in Salmonella typhimurium TA98 and TA100.
Mutat Res. 1988 Oct; 206(2):201-8.MR

Abstract

Four commercial ethanolic plant extracts, Tinctura Alchemillae, Extractum Crataegi, Extractum Myrtilli and Tinctura Hyperici, were tested for their mutagenicity in Salmonella typhimurium TA98 and TA100 with and without S9 mix obtained from rats pretreated with phenobarbital. The extracts studied differed greatly in their mutagenic potencies but exhibited a very similar mutation pattern in which the strongest effect was always seen in tester strain TA98 with S9 mix. Simultaneously we investigated the extracts for the presence of quercetin and kaempferol. Only quercetin was detected in small amounts by thin-layer chromatography (TLC). The fractions containing quercetin were separated and collected using a Sephadex LH-20 column. Two different methods were employed to estimate the amount of quercetin in the extracts: a colorimetric assay developed by Christ and Müller, and a complexometric method by Belikov. The quercetin concentrations ranged between 2 mg (Tinctura Alchemilla) and 89 mg (Tinctura Hyperici) per 100 g of extract. We suggest that the mutagenicity of the 4 plant extracts is mainly due to the presence of quercetin for the following reasons: (1) all the plant extracts exhibit a mutation pattern which is very similar to that of quercetin, (2) the mutagenic potential of the extracts correlates well with their quercetin content, considering the fact that plant extracts are very complex mixtures often containing toxic or antimutagenic compounds.
