RESUMO: O melão de São Caetano, planta trepadeira originaria do leste indiano e sul da Índia, é encontrada no bioma caatinga. Neste trabalho objetivou-se avaliar a biometria dos frutos e o número de sementes por fruto do melão de São Caetano. Os frutos foram coletados em área de vegetação nativa do campus da Universidade Federal Rural do Semi-Árido (UFERSA), situada no município de Mossoró, RN, seguindo para o laboratório de fitotecnia para a determinação das seguintes características: comprimento, diâmetro e peso dos frutos, bem como o número de sementes por fruto. As análises descritivas e gráficas foram realizadas utilizando o pacote estatístico software R-project. As variáveis, comprimento e diâmetro apresentaram baixa amplitude de variação e bons valores de coeficiente de variação. Já o peso do fruto e o número de sementes por fruto mostraram alta amplitude de variação. Verificou-se alto grau de simetria e distribuição mesocúrtica para todas as características avaliadas nesse estudo. Constatou-se também a correlação linear simples positiva significativa entre o comprimento e o diâmetro, e não significativa entre o peso e o número de sementes por fruto, e que os dados referentes a todas as características do fruto do melão de São Caetano avaliadas neste trabalho se ajustaram à distribuição normal de probabilidade, o que permite a realização de inferências com base estatística. Palavras-chave:Momordica charantia L., espécie trepadeira, estatística descritiva, inferência. ABSTRACT: Biometric evaluation of the characters of the melon from Sao Caetano (Momordica charantia L).The melon from Sao Caetano is a climbing plant, originally from India and South East India and is found in the savanna biome. This study aimed to evaluate the biometric fruit and the number of seeds per fruit of the melon Sao Caetano. The fruits were collected inside a native vegetation area of the campus at the Universidade Federal Rural do Semi-Árido (UFERSA), located in the city of Mossoró, RN. They were then taken to the laboratory of crop science, for the determination of the following characteristics: length, diameter and fruit weight as well as number of seeds per fruit. The descriptive and graphical analyzes were performed by using the statistical package R -project software. The length and diameter variables exhibited a low amplitude variation and a good value for the coefficient of variation. However, the fruit weight and number of seeds per fruit showed a high amplitude variation. There was a high degree of symmetry and a flattened distribution for all traits evaluated in this study. It was also found significant positive simple linear correlation between the length and diameter, and no significant difference between the weight and number of seeds per fruit. The data related to all features of the São Caetano melon fruit evaluated in this study were adjusted to normal distribution of probability which allows the performance of interferences with statistical basis.

“…Screening of medicinal plants for their anthelmintic activity has become the scenario of great scientific interest (Alemu et al, 2014). Ethnopharmacological surveys provide the rationale for selection and scientific investigation of medicinal plants, since some of these indigenous remedies are already in use by significant population over extended periods of time (Lans, 2001;Ferreira et al, 2013). Most of the pharmaceutical companies have some form of research programs investigating plants with the aim of creating allelochemicals (bioactive secondary compounds) and new marketable drugs.…”

Haemonchosis is one of the common helminthic diseases of ruminants which causes high mortality. Course of infection depends on the worm burden, age and nutrition of the host. The principal feature of Haemonchus species infection is anaemia. Anthelmintics with different modes of action are the necessity of the hour, which has changed the focus to other sources like plants. Screening of medicinal plants for their anthelmintic activity has become great scientific interest. Ethnopharmacological surveys provide the rationale for selection and scientific investigation of medicinal plants. Herbal drugs are extensively used as anthelmintics in the developed world before the era of broad spectrum drugs. Many currently available therapeutic compounds are plant derived or synthetic analogues derived from those compounds. Plants of the genus Artemisia were used against the nematodes Ascaris suum and Toxocara spp. as well as cestodes of poultry. From time immemorial, plant derivatives like Nicotiana tabaccum have been used against Moneizia, Ascaridia and several species of GI nematodes including Cooperia, Haemonchus, Nematodirus and Trichostrongylus. Arecoline and several other alkaloids from the dried ripe seeds of Areca catechu were found to be active against tapeworms in dogs and poultry. Aristolochia species of plant are traditionally used for neatodiasis in India. In this review an effort is made to compile the available reports and studies about the anthelmintic activity and use of different plants especially of Aristolochia with special reference to Haemonchosis.

“…In folk medicine, it has been used as diuretic, antipyretic, antidiabetic, antidotal, thirst-quenching agent and analgesic and antihypertensive agent (Chiu andChang 1995, Chen et al 2006). Ruellia tuberosa (L.) is used as cooling agent in urinary problems and uterine fibroids (Lans 2001 and2006). It has recently been incorporated as a component in an herbal drink in Taiwan (Balick et al 2000).…”

Antibacterial, antifungal and insecticidal activities of Ruellia tuberosa (L.) root extract

et al. 2014

Context: Plants as therapeutics are popularized for thousands of years and people continue to rely on them for health care until now due to their effectiveness, easy availability, low cost and comparatively being devoid of serious toxic effects. Microorganisms such as bacteria, fungi and insects are developing resistance to the current therapies very easily and the currently available antibacterial, antifungal agents and pesticides are very much costly and toxic. So the current shift to the use of herbal antibacterial, antifungal agents and pesticides may be more effective, economic and advantageous. Objectives: The present research was performed to investigate the antibacterial, antifungal and insecticidal activities of the methanolic extract of the dried root of the plant Ruellia tuberosa (L.). Materials and Methods: Five Gram (+) ve bacteria namely Staphylococcus aureus, Staphylococcus agalactiae, Bacillus cereus, Bacillus megaterium, Bacillus subtilis; five Gram (-) ve bacteria namelyPseudomonus aeruginosa, Escherichia coli, Shigella flexneri, Shigella dysenteriae, Shigella sonnei were used as test bacteria for testing the antibacterial activity of the plant extract. Antifungal activity was observed against six fungi namely Candida albicans, Aspergillus niger, Aspergillus ochreus, Aspergillus ustus, Rizopus oryzae and Trichophyton rubrum. The disc diffusion assay method was used in both the cases and standard Kanamycin disc (30µg/disc) was used as the reference standard. The test for insecticidal activity was performed by using surface film activity testing method and Tribolium castaneum (Herbst) was used as the test insect. Results: The methanol extract was active against all the bacteria and fungi tested and showed significant antibacterial and antifungal properties with the zone of inhibition 9 to 23 mm for antibacterial screening and 8 to 15 mm for antifungal screening. The insecticidal assay by surface film activity test also revealed strong insecticidal activity with 80% mortality rate of Tribolium castaneum (Herbst) at a dose of 50 mg/ml in 48 hours. Conclusion: From our experiment it is informed that Ruellia tuberosa (L.) may be used to treat bacterial and fungal diseases and also as insect repellant and it is also possible to isolate antibacterial, antifungal and insecticidal drug from this plant.
