Abstract Basil has aroused biological, pharmacological, agronomic and industrial interests, and stand out in the essential oil production. This study aimed to conduct cytogenetoxicity analysis through the Allium cepa L. test, of aqueous extracts and essential oil of basil (Ocimum basilicum L. “Basilicão”) grown under the conditions of presence or absence of induction to saline stress. The basil was grown in a greenhouse in two seasons, summer and winter, in which some of the plants received induction to saline stress (solution of electrical conductivity of 5 dSm-1) and the other part did not receive induction to saline stress (electric conductivity 1 dSm-1). With the collected plants, was prepare the aqueous extracts of the leaves (5 e 10 gL-1) and the extraction of essential oil of the leaves and inflorescences (0.10%) of basil, which were used for the cytogenetoxicity analysis by A. cepa test. Only the treatment with aqueous extract (5 gL-1) of basil grown under induction to saline stress and the treatment with aqueous extract (10 gL-1) of basil grown without induction to saline stress (both during the winter) are shown to have antiproliferative potential. As for the genotoxic potential, only the treatment with essential oil (0.10%) of plants which received induction to saline stress during the summer has that effect. The other treatments have not cytogenotoxic potential. biological pharmacological interests production L test Ocimum Basilicão “Basilicão” seasons winter solution dSm1 dSm dSm-1 electric dSm1. .

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 efeitos encontrados nesses extratos. Somente extratos da amostra de Santa Maria demonstraram potencial genotóxico.

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.

Punica granatum L., conhecida como romanzeira, é originária da Ásia e encontra-se distribuída por todo Brasil. É usada para o tratamento de doenças inflamatórias, infecciosas e respiratórias. Em decorrência da grande utilização de recursos fitoterápicos, é necessário esclarecer à população sobre a grande quantidade de substâncias existentes nas plantas e sobre os benefícios e prejuízos de tais substâncias à saúde. O presente trabalho objetivou realizar a análise cromatográfica e o estudo da genotoxicidade dos extratos aquosos das cascas dos frutos de P. granatum através do teste de Allium cepa L. Para a montagem do experimento, foram utilizados 7 tratamentos: T1-água destilada, T2-chá 5 g.L-1, T3-chá 10 g.L-1, T4-glifosato a 9,6%, T5-glifosato para recuperação em água destilada, T6-glifosato para recuperação em chá 5 g.L-1 e T7-glifosato para recuperação em chá 10 g.L-1. As radículas foram coletadas e fixadas em etanol:ácido acético (3:1) por 24 horas, e armazenadas em álcool 70%, sob refrigeração. Realizou-se análise por cromatografia líquida de alta eficiência para quantificação dos compostos fenólicos. Nos extratos de P. granatum foram observados em maior quantidade: ácido gálico, catequina, ácido cafeico e rutina. Além disso, os extratos demonstraram potencial antiproliferativo, sem apresentar atividade antimutagênica e genotóxica.

Punica granatum L., locally known as romanzeira, is native to Asia but found throughout Brazil. P. granatum is used for treating inflammatory, infectious and respiratory diseases. The aim of this study was to evaluate the chromatography and genotoxicity of an aqueous extract of P. granatum (pomegranate) fruit peel using the Allium cepa L. test. The experiment set-up entailed 7 treatments: T1-distilled water, T2-tea 5 g.L-1, T3-tea 10 g.L-1, T4-glyphosate at 9.6%, T5-glyphosate with subsequent recovery in distilled water, T6-glyphosate with subsequent recovery in tea 5 g.L-1 and T7-glyphosate with subsequent recovery in tea 10 g.L-1. The rootlets were collected and fixed in ethanol:acetic acid (3:1) for 24 hours, then stored in 70% ethanol under refrigeration. Analysis was performed using high performance liquid chromatography for the quantification of the extracted phenolic compounds. Gallic acid, catechin, caffeic acid, and rutin were abundant in the extracts of P. granatum. The extracts were found to exhibit antiproliferative potential but not antimutagenic or genotoxic activity.
