El banano, principal producto de exportación en Colombia, presenta muchos retos técnicos como el control de la tortuguilla (Colaspis sp.), causante del 33% de pérdidas económicas; dado que los estándares de calidad no permiten la presencia de residuos químicos presentes en los frutos, se evaluó en un cultivo comercial, del municipio de los Córdobas, el efecto de extractos vegetales en el manejo de la tortuguilla. Se evaluó la severidad del ataque a partir del número de roeduras en frutos y la incidencia en racimos y frutos tratados. Los extractos utilizados fueron salvia Salvia officinalis L., anamú Petiveria alliacea L., albahaca Ocimum basilicum L., ajo Allium sativum L. y ají picante Capsicum annuum asperjados con una bomba tipo jardinera sobre bolsas comerciales de polietileno; dejándose expuestas durante una hora para asegurar la adherencia del producto. Se estableció un diseño completamente al azar con siete tratamientos, tres repeticiones, un testigo relativo (bolsa sin extracto vegetal) y un testigo absoluto (racimos sin embolsar); registrando la severidad del daño causado. Los resultados mostraron que los frutos provenientes de racimos embolsados presentaron menor severidad que los frutos no embolsados y los tratamientos constituidos por bolsas impregnadas con extracto de ajo presentaron menor incidencia y grado de severidad, mostrando una disminución del daño en un 98%. Concluyendo que el extracto de ajó fue el producto repelente que mejor acción mostro al daño de fruto. Los tratamientos donde se aplicó Albaca, Ají, Salvia y Anamú se pudieron determinar una mayor incidencia y daño de fruto.

Abstract The aim of this study was to investigate whether powdered plants of different species namely: peppermint Mentha piperita (L.) (Lamiaceae), wormwood Artemisia absinthium (L.) (Asteraceae), common sage Salvia officinalis (L.) (Lamiaceae), allspice Pimenta dioica (Linnaeus et Merrill) (Myrtaceae) and common garlic Allium sativum (L.) (Amaryllidaceae), added to semolina using concentrations of 1.23, 3.61, and 5.88%, influence the mortality rate in the saw-toothed grain beetle Oryzaephilus surinamensis Linnaeus, 1758 (Coleoptera: Silvanidae). Experiments were conducted in a laboratory at 28°C and relative humidity 60±5%. At the concentration of 1.23%, allspice seeds caused the highest mortality amongst the saw-toothed grain beetle. When concentrations of 3.61 and 5.88% were used, sage, peppermint and wormwood caused the highest statistically significant mortality of O. surinamensis

Celem pracy było określenie poziomu zanieczyszczenia grzybami strzępkowymi suszonych ziół oraz przypraw dostępnych w sprzedaży detalicznej w sklepach ekologicznych i hipermarketach województwa łódzkiego. Badaniami objęto 13 rodzajów produktów: czosnek (Allium sativum), koper (Anethum graveolens), natkę pietruszki (Petroselinum crispum), bazylię (Ocimum basilicum), oregano (Origanum vulgare), estragon (Artemisia dracunculus), tymianek (Thymus vulgaris), majeranek (Origanum majorana), gałkę muszkatołową (Myristica fragans), curry (Helichrysum angustifolia), kurkumę (Curcuma longa), pieprz czarny (Piper nigrum), paprykę słodką (Capsicum annuum). Analiza mikrobiologiczna obejmowała oznaczenie liczby grzybów pleśniowych i ich skład jakościowy. Zanieczyszczenie badanych ziół oraz przypraw przez grzyby strzępkowe było zróżnicowane i nie przekraczało poziomu 104 jtk∙g-1.W czterech produktach: bazylii, curry, kurkumie i papryce słodkiej próbki zakupione w hipermarkecie charakteryzowały się istotnie większym zanieczyszczeniem przez pleśnie w porównaniu z próbkami pochodzącymi ze sklepu ekologicznego. Wykazano brak zróżnicowania poziomu zanieczyszczenia grzybami strzępkowymi badanych produktów w zależności od miejsca zakupu. Średnia liczba pleśni w ziołach i przyprawach zakupionych w sklepach ekologicznych oraz w produktach pochodzących z hipermarketu kształtowała się na podobnym poziomie. Stwierdzono natomiast zróżnicowanie poziomu zanieczyszczenia pleśniami w zależności od rodzaju przyprawy. Wyizolowane z suszonych ziół oraz przypraw grzyby strzępkowe należały łącznie do 5 rodzajów. Zidentyfikowano pleśnie z rodzaju Aspergillus (A. niger, A. flavus), Penicillium, Mucor, Alternaria i Cladosporium.

A "hérnia das crucíferas" é a principal doença na produção de brássicas na Região Metropolitana de Curitiba-PR. Fatores ambientais favoráveis, ausência de cultivares resistentes e de controle químico eficiente, aliados ao plantio sucessivo de espécies da mesma família, têm colaborado para sua disseminação. Com o objetivo de controlar a doença com menor impacto ambiental, o presente estudo verificou o efeito do pré-plantio de plantas medicinais e aromáticas na redução de inóculo de Plasmodiophora brassicae. Dois experimentos foram conduzidos em casa de vegetação no Setor de Ciências Agrárias da Universidade Federal do Paraná, nos períodos de junho a novembro de 2003 e julho a dezembro de 2004. O delineamento foi inteiramente casualizado com nove tratamentos e seis repetições. As plantas utilizadas nos tratamentos foram: menta (Mentha piperita L.); alfavaca (Ocimum basilicum L.); bardana (Arctium minus Hill); calêndula (Calendula officinalis L.); cebolinha (Allium fistulosum L.); salsa (Petroselinum hortense Hoffm) e sálvia (Salvia officinalis L.), e como testemunhas foram utilizados solos sem patógeno e solo infestado, ambos em pousio. Utilizaram-se vasos contendo 3 Kg de solo esterilizado via vapor e como inóculo de P. brassicae foram utilizados 2,5 g de galhas por vaso. A rúcula (Eruca sativa Mill) foi o hospedeiro suscetível utilizado. Após 45 dias do plantio da rúcula foram determinadas a massa aérea fresca, incidência de galhas galhas e o índice de severidade. A maior massa aérea fresca e as menores severidades foram obtidas no experimento de 2003, nos tratamentos com o pré-plantio das medicinais bardana, salsa, menta, alfavaca e cebolinha.

Salvia Officinalis L

Culinary sage (Salvia officinalis L.) is a common spice plant in the mint family (Lamiaceae) well known for its distinctive culinary and traditional medicinal uses. Sage tea has been used traditionally as a brain-enhancing tonic and extracts from sage have been reported to have both cognitive and memory enhancing effects. Brain-derived neurotrophic factor (BDNF) is an endogenous signaling molecule involved in cognition and memory function. In this study, activity-guided fractionation employing preparative reverse-phase high performance liquid chromatography (RP-HPLC) of culinary sage extracts led to the discovery of benzyl 6-O-β-D-apiofuranosyl-β-D-glucoside (B6AG) as a natural product that upregulates transcription of neurotrophic factors in C6 glioma cells. Purified B6AG showed a moderate dose response, with upregulation of BDNF and with EC50 at 6.46 μM. To better understand the natural variation in culinary sage, B6AG was quantitated in the leaves of several commercial varieties by liquid chromatography-mass spectrometry (LC-MS). The level of B6AG in dried culinary sage was found to range from 334 ± 14 to 698 ± 65 μg/g. This study provided a foundation for future investigations, including quantitative inquiries on the distribution of B6AG within the different plant organs, explorations in optimizing post-harvest practices, and aid in the development of sage varieties with elevated levels of B6AG.
