ABSTRACT The plant-pathogenic bacterium Xanthomonas citri subsp. is the causal agent of Asiatic citrus canker, a serious disease that affects all cultivars in subtropical citrus-producing areas worldwide. There no curative treatment for canker; thus, eradication infected plants constitutes only effective control spread X. . Since program state São Paulo, Brazil, under threat, there clear risk becoming endemic main orange-producing area world. Here we evaluated potential use alkyl gallates to...
A utilização de produtos naturais na medicina popular é milenar e persiste até os dias atuais. Entretanto, a idéia que estes são isentos toxicidade torna o uso medicamentos fitoterápicos cada vez maior indiscriminado. Este trabalho trata uma revisão sobre as interações podem ocorrer com concomitante Hypericum perforatum L. (erva joão) Piper methysticum F. (kava-kava) fármacos, podendo levar sérios efeitos tóxicos, incluindo fatalidade.
A compactação do solo diminui o crescimento radicular, podendo afetar tanto desenvolvimento quanto a produtividade da soja. No presente trabalho, estudaram-se os efeitos subsuperficial na morfologia radicular soja (Glycine max L. Merrill), procurando relacioná-los ao e à nutrição planta. O 'Primavera' foi cultivado até 37 dias emergência, em vasos onde camada de 15-18,5 cm profundidade campactada 1,03, 1,25, 1,48 1,72 g/cm³, um latossolo vermelho-escuro com 80% areia 16% argila cuja...
Considerando-se a qualidade dos fitoterápicos, é importante salientar que preocupação com esta questão inclui rigoroso acompanhamento das diferentes etapas do desenvolvimento e produção destes produtos, desde coleta vegetal até disponibilidade produto final. Neste trabalho, foram realizados o controle da qualidade, potencial antioxidante como também ensaios biológicos in vitro fruto goiabeira (Psidium guajava L.), para de uma formulação fitocosmética.

The present work aimed to evaluate the effect fungitoxic of plant extracts on mycelial growth and spores germination C. gloeosporioides. were obtained starting from dried ground plants, using water ethilic alcohol as extractor. Twenty-two species used obtain extracts. tested by means incorporation 20% (v/v) in PDA medium, before or after sterilization. percentage inhibition (PIM) was determined. Extract proportion 50% added a spore suspension determine (PIS). hidroetanolic provided larger...
Considerando-se a qualidade dos fitoterápicos, é importante salientar que preocupação com esta questão inclui rigoroso acompanhamento das diferentes etapas do desenvolvimento e produção destes produtos, desde coleta vegetal até disponibilidade produto final. Neste trabalho foi realizado o controle da fruto de Syzygium cumini (L.) Skeels, popularmente conhecido como jambolão. Para físico-químico microbiológico utilizaram-se metodologias farmacopéicas não farmacopeicas. Os resultados obtidos...
Azadirachta indica A. Juss, known as neem (Meliacea family), has insecticide and pesticide properties, many studies have shown their efficacy antifungal, anti-inflammatory, among others. Studies for the development of drugs from plants are rising due to several factors such bacterial resistance, indiscriminate use adverse reactions antibiotics. In this study, phytochemical triage thin layer chromatography analysis were performed, with similar results presence flavonoids, tannins terpenes....
Garlic (Allium sativum L.) is grown all over the world as seasoning and medicinal vegetable since 3,000 BC. Allicin main component of garlic, being attributed to it most its biological activities, such bactericidal, antifungal antiviral actions. However, other compounds garlic present antioxidant, hypocholesterolemic, vasodilator protective action against different types cancer, immunomodulatory. Fungal infections are important causes morbidity mortality in people mainly immunosuppressed...
We evaluated the potential antitubercular activity of triterpenes obtained from leaves and bark Byrsonima crassa. From chloroform extracts leaves, by bioassay-guided fractionation, we mixtures known triterpenes: α-amyrin, β-amyrin their acetates, lupeol, oleanolic acid, ursolic acid α-amyrinone. Tested against Mycobacterium tuberculosis, exhibited minimum inhibitory concentrations (MICs) 31.25 - 312.25 µg/mL. friedelin, isolated extract bark, showed MICs 125 µg/mL respectively. This is first...
The infections by protozoans of the genus Leishmania are a major worldwide health problem, with high endemicity in developing countries. drugs choice for treatment leishmaniasis pentavalent antimonials, which cause renal and cardiac toxicity. As part search new against leishmaniasis, we evaluated vitro protease inhibition activity extracts (hexanic, ethyl-acetate, ethanolic) fukugetin, bioflavonoid purified from ethyl-acetate extract pericarp fruit Garcinia brasiliensis, tree native to...
In this work, chemical and biological activities of crude extracts obtained with 50% ethanol, 70% acetone:water (7:3; v/v) chloroform Plinia cauliflora (DC.) Kausel, Myrtaceae, leaves, a native tree from several regions Brazil, was investigated. Histochemical phytochemical screenings were done according to characterization reactions thin layer chromatography. To assist in standardization, total phenol flavonoids content spectrophotometric performed. Antioxidant activity analyzed by...
Bioassay-guided fractionation of the chloroform extract Byrsonima fagifolia leaves led to isolation active antitubercular compounds alkane dotriacontane (Minimal Inhibitory Concentration-MIC, 62.5 μg mL(-1)), triterpenoids as bassic acid (MIC = 2.5 α-amyrin acetate a mixture lupeol, α- and β-amyrin 31.5 mL(-1)) acetates mL(-1)). The antimycobacterial activity was determined by Microplate Alamar Blue Assay (MABA) structures promising were spectroscopic analysis. This investigation constitutes...
Casearia sylvestris Swartz (Salicaceae) has been used in traditional medicine and its leaf extracts have exhibited important pharmacological activities. The species presents morphological, chemical genetic variation. Two varieties are considered due external morphological differences: C. var. lingua. There difficulties definition of these varieties. objective this work is to evaluate morpho-anatomical differences between that can be applied their distinction for pharmaceutical or botanical...
