Summary: | Peltodon longipes is used as a stimulant and emmenagogue. The objective of this study was to perform genotoxic and chromatographic analyses of the extracts of two samples of P. longipes, collected from the cities of Santa Maria and Tupanciretã, RS, Brazil. The Allium cepa assay was used to analyze genotoxicity while high-performance liquid chromatography was employed to determine phenolic compounds. The genotoxicity experiment consisted of nine groups each comprising four A. cepa bulbs. Bulb roots were developed in distilled water and then transferred for the treatments, for 24 hours, and the negative control remained in water. The treatments were: aqueous extracts at concentrations of 5 and 15 g L-1 for each sample, plus four groups treated with 1% glyphosate, one of which was used as a positive control and the other three for testing DNA damage recovery using water and the extracts of P. longipes from Santa Maria. All extracts of P. longipes exhibited anti-proliferative potential, although the effect was significantly greater for the extracts from the Tupanciretã sample. This sample also contained the highest amount of rosmarinic acid and kaempferol, which may confer the effects found in these extracts. Only extracts from the Santa Maria sample exhibited genotoxic potential.
Peltodon longipes é utilizada como estimulante e emenagoga. Objetivou-se realizar análises genotóxica e cromatográfica dos extratos de duas amostras de P. longipes, coletadas nos municípios de Santa Maria e Tupanciretã, RS, Brasil. O teste de Allium cepa foi utilizado para análise da genotoxicidade e a cromatografia líquida de alta eficiência, para determinação dos compostos fenólicos. O experimento de genotoxicidade constou de nove grupos de quatro bulbos de A. cepa. Os bulbos foram enraizados em água destilada e após transferidos para os tratamentos, por 24 horas, permanecendo o controle negativo em água. Os tratamentos foram: extratos aquosos nas concentrações de 5 e 15 g L-1 de cada amostra, além de quatro grupos tratados com glifosato 1%, um deles usado como controle positivo e outros três para testar a recuperação de danos ao DNA, utilizando água e os extratos de P. longipes da amostra de Santa Maria. Todos os extratos de P. longipes demonstraram potencial antiproliferativo, porém o efeito foi significativamente maior para os extratos da amostra de Tupanciretã. Essa amostra também apresentou maior quantidade de ácido rosmarínico e canferol, o que pode estar relacionado com os e |
