Antimicrobial and anti-inflammatory activities of the volatile oil compounds from Tropaeolum majus L. (Nasturtium)

Abstract

This study was carried out to evaluate the antimicrobial and anti-inflammatory activity of some chemical compounds of the volatile oil extracted from Tropaeolum majus L. The chemical compounds extracted from the flowers and leaves of T. majus L. have been identified through color reactions and gas-chromatographic analysis combined with mass spectrometry. Quantitative testing and the ascertaining of the minimum inhibitory concentration (MIC) have been done through the binary micro dilution method for liquid environments against the following microbial types and species. The qualitative evaluation of the sensitivity of microbial stems against these compounds has been done through methods that have been adapted from the diffusimetric method. Of the qualitative methods used for the control of the antimicrobial activity, the method of diffusion on filter paper discs proved to be the most efficient, the results correlating well with the MIC. Our studies have demonstrated the efficiency of the natural compounds' of T. majus L. in anti-inflammatory treatments in animals. The antimicrobial activity proved to be selective, depending on the pathogen. These results are in agreement with those of other studies. Our results supported the selection and utilization of these compounds' as antimicrobial agents in the treatment of infections with microorganisms resistant to existent antibiotics.

Comparative characteristics of Lupinus albus L. and Lupinus luteus L. under allelopathic effect of Sorghum halepense L. (Pers.)

“…It may affect seed germination, root development and absorption of nutrients. In most cases, the influence is inhibitory, which explains why some plants do not grow in the presence of particular other plants (Sexton еt al., 2002;Butnariu & Bostan, 2011;Golubinova & Ilieva, 2014). In order to determine an allelopathic relationship between certain weeds and crop plants, Moosavi et al (2011) and Nouri et al (2012) used plant extracts from dry weed biomass because such extracts had significantly higher concentrations than plants growing in agrophytocenoses.…”

“…Outros carotenoides presentes nela são a violaxantina, anteraxantina, zeaxantina, zeinoxantina, β-criptoxantina, α-caroteno e βcaroteno. Eles possuem papel biológico semelhante, podendo auxiliar na cicatrização de tecidos, protetores de pele, antioxidantes, precursores de vitaminas e no auxílio ao combate de doenças oculares como a catarata (RONCHETI, 2018;BUTNARIU et al, 2011BUTNARIU et al, , 2016JAKUBCZYK et al, 2018;NIIZU;RODRIGUEZ-AMAYA, 2005).…”

“…A luteína é o principal pigmento carotenoide, responsável pela coloração amarela e o mais abundante na planta, suas flores amarelas possuem 450 ± 60 μg/g e as alaranjadas 350 ± 50 μg/g de luteína, concentrações acima das vermelhas, que possuem mais antocianinas. Esses carotenoides atuam de forma protetora na planta e quando consumidos podem fornecer ações cicatrizante de tecidos, protetora de pele, antioxidante, precursora de vitaminas e no auxílio ao combate de doenças oculares como a catarata (RONCHETI, 2018;JAKUBCZYK et al, 2018;BUTNARIU et al, 2011BUTNARIU et al, , 2016.…”
