Los aceites esenciales son compuestos orgánicos importantes en el sector farmacéutico debido a sus propiedades antimicrobianas, volviéndose una alternativa de solución para determinadas fitopatologías. En el presente estudio se evaluó in vitro la actividad inhibitoria de aceites esenciales de Curcuma longa y Zingiber officinale contra Colletotrichum sp. obtenidas a partir de cultivos de Dioscorea rotundata en Toluviejo (Sucre, Colombia). Concentraciones de 3,000; 5,000; 8,000 y 10,000 mg/L de extracciones de aceite (método de hidrodestilación asistida por microondas) fueron aplicados a cultivos in vitro del hongo. Además, se empleó un testigo absoluto y controles positivo y negativo. Los aceites fueron caracterizados por cromatografía de gases acoplado a espectrometría de masa. La actividad inhibitoria se realizó por medio de la prueba de siembra en superficie (porcentaje de índice de inhibición). Los mayores valores de índice antifúngico se observaron a 10,000 mg/L similar al obtenido con el control positivo por benomil. De la caracterización química de los aceites esenciales el metabolito secundario que se presentó con mayor rango fue el monoterpeno 3-Thujeno y el citral. Los aceites esenciales de C. longa y Z. officinale generaron actividad inhibitoria contra el crecimiento de Colletotrichum sp., y por lo tanto pueden ser empleados para reducir la antracnosis.

Alzheimer's disease (AD) is linked to an extensive neuron loss via accumulation of amyloid-beta (Aβ) as senile plaques associated with reactive astrocytes and microglial activation in the brain. The objective of this study was to assess the therapeutic effect of WS-5 ethanol extract in vitro and in vivo against Aβ-induced AD in mice and to identify the extract’s active constituents. In the present study, WS-5 exerted a significant inhibitory effect on acetylcholinesterase (AChE). Analysis by transmission electron microscopy (TEM) revealed that WS-5 prevented Aβ oligomerization via inhibition of Aβ1-42 aggregation. Evaluation of antioxidant activities using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) demonstrated that WS-5 possessed a high antioxidant activity, which was confirmed by measuring the total antioxidant status (TAS). Furthermore, the anti-inflammatory properties of WS-5 were examined using lipopolysaccharide-stimulated BV-2 microglial cells. WS-5 significantly inhibited the lipopolysaccharide–induced production of nitric oxide and two proinflammatory cytokines, TNF-α and IL-6. The memory impairment in mice with Aβ-induced AD was studied using the Morris water maze and passive avoidance test. Immunohistochemistry was performed to monitor pathological changes in the hippocampus and cortex region of the mouse brain. The animal study showed that WS-5 (250 mg/kg) treatment improved learning and suppressed memory impairment as well as reduced Aβ plaque accumulation in Aβ-induced AD. HPLC analysis identified the extract’s active compounds that exert anti-AChE activity. In summary, our findings suggest that WS-5 could be applied as a natural product therapy with a focus on neuroinflammation-related neurodegenerative disorders.

Neste trabalho, objetivou-se avaliar o efeito de extratos e óleos essenciais de quatorze plantas medicinais e ou nativas, conhecidas popularmente no Norte de Minas Gerais, sobre a germinação de esporos e crescimento micelial do fungo Colletotrichum gloeosporioides. Foram utilizados no teste de inibição do crescimento micelial, os extratos aquosos de alecrim (Rosmarinus officinalis), erva baleeira (Cordia verbenacea), joá (Solanum sisymbriifolium), quebra-pedra (Phyllanthus corcovadensis), erva botão (Eclipta alba) e açafrão da índia (Curcuma longa) obtidos por meio do processo de infusão; óleo essencial de alecrim de vargem (Família Lamiaceae), alecrim pimenta (Lippia sidoides), alfavaca cravo (Ocimum gratissimum), lippia (Lippia citriodora), goiaba branca (Psidium guajava), capim santo (Cymbopogon citratus); óleo resina de copaíba (Copaifera langsdorffi); hidrolatos de alecrim de vargem, goiaba vermelha (Psidium guajava), lippia, capim santo, goiaba branca, alfavaca cravo; manipueira de (Manihot esculenta). Também foram testados esses mesmos hidrolatos e os óleos essenciais na germinação dos esporos do fungo. Todos os tratamentos foram realizados in vitro, cultivando-se o fungo em meio de cultura BDA acrescido de 100μL dos compostos vegetais. No teste de inibição da germinação, todos os óleos essenciais impediram a germinação do fungo. No entanto, os hidrolatos não tiveram esse efeito. No teste de crescimento micelial, os óleos essenciais de todas as plantas inibiram completamente o crescimento do fungo, exceto o óleo da goiaba branca. Os extratos aquosos, a manipueira, o óleo resina e os hidrolatos, também não foram eficientes sobre o crescimento do patógeno. Esses resultados indicam o potencial antifúngico de alguns óleos essenciais de plantas medicinais.

El ñame (Dioscorea spp) es afectado por diferentes patógenos, entre los que se destaca Colletotrichum gloeosporioides, agente causal de la antracnosis. Esta enfermedad reduce la eficiencia fotosintética de la planta y ocasiona pérdidas en la producción de más del 90% en variedades susceptibles y disminución en la calidad de los tubérculos. El objetivo de este estudio fue evaluar la reacción de genotipos de ñame, en la colección de la Universidad de Sucre, a la antracnosis. Se realizaron inoculaciones con cuatro aislados de C. gloeosporioides en 19 accesiones, correspondientes a las especies Dioscorea alata (diez), Dioscorea rotundata (siete), Dioscorea cayenensis (una), y Dioscorea trífida (una); mediante aspersión de esporas en hojas de plantas in vitro. Se encontró diferencia altamente significativa en la reacción del germoplasma de ñame a la antracnosis (F= 80,37; gl= 18; p menor que 0,0000), sin embargo los aislados evaluados no mostraron diferencia significativa en su agresividad (F= 1,71; gl= 3; p menor que 0,1762). D. trifida presentó la mayor resistencia, seguida de D. cayenensis y D. rotundata; mientras que D. alata fue la especie más susceptible.

The Impact

Although the impact of medicinal and culinary herbs on health and disease has been studied to varying extents, scarcely little is known about the impact of these herbs on gut microbiota and how such effects might contribute to their health benefits. We applied in vitro anaerobic cultivation of human fecal microbiota followed by 16S rRNA sequencing to study the modulatory effects of 4 culinary spices: Curcuma longa (turmeric), Zingiber officinale (ginger), Piper longum (pipli or long pepper), and Piper nigrum (black pepper). All herbs analyzed possessed substantial power to modulate fecal bacterial communities to include potential prebiotic and beneficial repressive effects. We additionally analyzed the sugar composition of each herb by mass spectrometry and conducted genome reconstruction of 11 relevant sugar utilization pathways, glycosyl hydrolase gene representation, and both butyrate and propionate biosynthesis potential to facilitate our ability to functionally interpret microbiota profiles. Results indicated that sugar composition is not predictive of the taxa responding to each herb; however, glycosyl hydrolase gene representation is strongly modulated by each herb, suggesting that polysaccharide substrates present in herbs provide selective potential on gut communities. Additionally, we conclude that catabolism of herbs by gut communities primarily involves sugar fermentation at the expense of amino acid metabolism. Among the herbs analyzed, only turmeric induced changes in community composition that are predicted to increase butyrate-producing taxa. Our data suggests that substrates present in culinary spices may drive beneficial alterations in gut communities thereby altering their collective metabolism to contribute to the salubrious effects on digestive efficiency and health. These results support the potential value of further investigations in human subjects to delineate whether the metabolism of these herbs contributes to documented and yet to be discovered health benefits.

Abnormal increase in the level of more than any one of the lipoproteins such as triglycerides, cholesterol, LDL or VLDL in the bloodstream can be defined as hyperlipidemia. It is the greatest world is often overused so, use “the most significant” instead of the greatestrisk factor of coronary heart attack and stroke.This review emphasizes on some herbal medicinal plants with their extracts, including Glycyrrhiza glabra,Legenaria siceraria,Medicago sativa,Curcuma longa,Curatella americana, Glycine max, Hibisus rosa-sinesis, Hibisus sabdariffa, Cinnamomum tamala, Withania somnifera, Cassia auriculata, Cynaras scolymus, Eugenia jambolana, Adenanthera pavonia, Garcinia cambogia, Terminalia chebula, Ixora coccinea, Carica papaya, Lycimum barbarum, Bauhinia purpurea, Syzygium alternifolium, Vitex negundo, Piper longa, Moringa oleifera, Zingiber officinale, Trigonella foenum graecum, Carum carvi, Gloriosasuperba, Ficus infectoria, Ficus glomerata for anti-hyperlipidemic potential. Decrease in the levels of these lipoproteins like, triglycerides (TG), Total cholesterol (TC), Very low density lipoprotein (VLDL) and low-density lipoprotein (LDL)includes some mechanisms actions of these medicinal plants observed in triton-x, cholesterol, high fat diet, Poloxamer-407, Dexamethasone and alloxan-induced in-vivo and in-vitro models. Accordingly, this review provides numerous evidenceswhichindicatethat these medicinal plants can be usedfor treating and preventinghyperlipidemia and related complications.
