  • Aspectos ecológicos y distribución de Tropaeolum tuberosum ssp. silvestre (Tropaeolaceae) en Argentina
    Sociedad Argentina de Botánica, 2012
    Co-Authors: Eva Bulacio, Hugo Ayarde
    Abstract:

    Tropaeolum tuberosum Ruiz et Pav. ssp. silvestre Sparre es una hierba rizomatosa trepadora que en Argentina fue encontrada en las Sierras de Calilegua (Jujuy) y en áreas montanas de Catamarca, aunque de esta última localidad sólo se conoce un único e incompleto ejemplar. Habita quebradas húmedas, entre los 2.100 y 2.650 m s.n.m., en el límite superior del bosque montano. El tallo es grácil de hasta 3 m de largo y la porción subterránea está constituida por rizomas alargados y de hasta 1 cm de diámetro. Estas son las principales diferencias con la ssp. tuberosum, en la cual el tallo es más corto, erguido y desarrolla tubérculos bien definidos.Ecological features and distribution of Tropaeolum tuberosum ssp. silvestre (Tropaeolaceae) in Argentina. Tropaeolum tuberosum Ruiz et Pav. ssp. silvestre Sparre is a rhizomatous climbing herb that in Argentina was found in the Sierras of Calilegua (Jujuy) and Catamarca mountains, yet of this last locality only is known an one and incomplete specimen. It inhabits humid gorges, between 2100-2650 masl, in the upper limit of the montane forest. The slender stem reaches 3 meters in lenght and the underground portion shows elongated rhizomes up to 1 cm in diameter. These are the main differences with the ssp. tuberosum, in which the stem is shorter, erect and develop well-defned tubers

    Abstract:

    Abstract Tropaeolum majus L., Tropaeolaceae, popularly known in Brazil as ‘capuchinha’ is widely used due its anti-inflammatory, antiseptic, anti-hypertensive and anti-depressive properties. However, scientific investigations about its effects on the central nervous system are still scarce. This study investigated the central pharmacological actions of the prolonged treatment with a hydroethanolic extract of T. majus in male Wistar rats in the elevated plus maze and hole-board behavioral models. For this, rats were daily treated with distillated water (negative control); diazepam (1 mg/kg) or hydroethanolic extract of T. majus (75, 150 and 300 mg/kg), for 29 days (by gavage) and were submitted to elevated plus maze and hole-board. Animals treated with all hydroethanolic extract of T. majus or diazepam doses increased the percentage of entries in open arms when compared to control group. However, only treatment with diazepam increased the length of time spent in the open arms of the elevated plus maze. No differences between all groups were observed regardless rearing, grooming, stretched-attend postures and defecation rates. In the HB test, in opposite to diazepam, treatment with hydroethanolic extract of T. majus did not interfere in the exploratory activity of rats. The hydroethanolic extract of T. majus promotes anxiolytic-like effects when orally administered in rats.

  • fetopathies associated with exposure to angiotensin converting enzyme inhibitor from tropaeolum majus l
    Drug and Chemical Toxicology, 2017
    Co-Authors: Emerson Luiz Botelho Lourenço, Anderson Joel Martinoandrade, Rita De Cassia Lima Ribeiro, Valdinei De Oliveira Araujo, Paulo Roberto Dalsenter, Arquimedes Gasparotto
    Abstract:

    AbstractThe prevalence of the use of herbal medicines is on the rise across the world, especially amongst pregnant women. A fact that draws attention is that many species commonly used by pregnant women, including the Tropaeolum majus L. (Tropaeolaceae), also present inhibitory activity on the angiotensin-converting enzyme (ACE). Herein, we have investigated the effects of T. majus extract (HETM) on fetal development, evaluating its relationship with possible ACE inhibitory activity. Pregnant Wistar rats were treated with different HETM doses (3, 30 and 300 mg/kg/day) from gestational days 8–20. Rats were sacrificed on the day 20 of pregnancy and the following parameters were evaluated: clinical symptoms of maternal toxicity; maternal body weight; feed and water intake; maternal liver, kidney, and ovary weights, maternal ACE activity and aldosterone levels, live fetuses mean; dead fetuses percentage, fetus weight, and fetal malformation. All pregnant rats treated with high HETM doses showed significant re...

  • protective cardiorenal effects of tropaeolum majus l in rats with renovascular hypertension
    Journal of Young Pharmacists, 2017
    Co-Authors: Arquimedes Gasparotto, Thiago Bruno Lima Prando, Karimi Sater Gebara, Francislaine Aparecida Dos Reis Livero, Denis Pires De Lima, Roberto Da Silva Gomes, Francielly Mourão Gasparotto, Emerson Luiz Botelho Lourenço
    Abstract:

    Background: Tropaeolum majus L. (Tropaeolaceae) is an important medicinal plant belonging to the Tropaeolaceae family, which has 80 species distributed in South and Central America. In Brazil, it is distributed practically throughout the entire territory and it is popularly known as “capuchinha”. In folk medicine its leaves are widely used for treatment of cardiovascular disorders. Despite consistent data showing some acute effects on renal and cardiovascular system, no study has investigated whether Tropaeolum majus extracts is able to exert cardiorenal protective effects after 30 days of treatment, i.e. in a sustained manner. Objective: Investigate the prolonged cardiorenal protective effects of ethanolic extract obtained from Tropaeolum majus (EETM) in rats with renovascular hypertension. Material and Methods: First, EETM was obtained and chemically characterized. Then, we investigated the possible antihypertensive and diuretics effects, including effects on renal haemodynamics, after prolonged treatment (30 days) with EETM (3, 30 and 300 mg/kg). Finally, we examined whether treatment with EETM may affect the angiotensin-converting enzyme (ACE) and oxidative stress, preventing heart and kidney damage in two-kidney, one-clip (2K1C) Goldblatt hypertensive rats. Results: Prolonged treatment with EETM was able to prevent the evolution of renovascular hypertension in 2K1C rats, inducing important renoprotective effects and reducing systemic blood pressure and cardiac hypertrophy. Moreover, it was also identified that these effects may be directly related to significant ACE inhibitory activity and reduction of oxidative stress. Conclusion: This study has brought new scientific evidence of preclinical efficacy of EETM as a cardiorenal protective agent in rats with renovascular hypertension. Key words: Antihypertensive, Cardioprotective, Diuretic, Renoprotective, Tropaeolum majus L.

    Abstract:

    Abstract Tropaeolum majus L. (Tropaeolaceae), commonly known as nasturtium, is an important edible plant native to the Andean States and widely disseminated throughout South America. Despite the use of this species is quite widespread, there are no minimum quality control standards or data on its genotoxicity. So, the aim of this study was to present a detailed anatomical and histochemical study for Tropaeolum majus and provide genotoxicity parameters of a preparation routinely used in South American countries. First, three different Tropaeolum majus aqueous extracts (TMAEs) at concentrations of 1.5%, 7%, and 15% were prepared according to the popular use. Then, genetic toxicity of TMAE was evaluated on bacterial reverse mutation, genomic lesions, and micronucleus formation in male rats. Furthermore, a detailed anatomical and histochemical study of the leaves and stems of Tropaeolum majus were performed. No revertant colonies were found in any bacterial cultures examined. In the comet assay, TMAE showed n...
