The agricultural sector has been searching for eco-friendly methods pest control. Essential oil-based formulations are promising alternatives. Here, we developed a nanoemulsion based on Piper tuberculatum Jacq. essential oil to control Bemisia tabaci biotype B. oils extracted from P. leaves were mostly composed of β-caryophyllene (16.86%), germacrene D (13.39%), and α-pinene (11.60%). Nanoemulsions containing significantly toxic adults 24 h after cabbage leaf treatment. lethal concentration...
Croton zehntneri (Euphorbiaceae) is a native aromatic plant from Northeast region of Brazil. The monoterpenoid estragole (ESL) has been isolated by classical chromatographic methods the essential oil (EO) C. zehnteneri leaves and characterized GC-FID GC-MS, its antimicrobial cytotoxic potentials being assessed. analysis EO enabled identification 100% integrated constituents, which yield was about 1.8%. main components identified were: eucalyptol, (84.7%) spathulenol. dosage 50 μg/disk ESL...
The cashew tree (Anacardium occidentale) represents one of the major cheapest sources non-isoprenoid phenolic lipids, which have a variety biological properties: they can act as molluscicides, insecticides, fungicides, anti-termite properties, medicinal applications, and demonstrate antioxidant activity in vitro.Immature nut-shell liquid (iCNSL) is unique natural source unsaturated long-chain phenols.Their use has stimulated much research order to prepare drug analogues for application...
The essential oil of Schinus terebinthifolius (Anacardiaceae) was analyzed by GC and GC-MS. α-Fenchene, limonene, β-pinene, α-phellandrene, β-isosylvestrene represent about 80% the composition. reproductive toxicity in Wistar male rats evaluated. No changes were observed mass organs, number morphology spermatozoa, rates, body offspring after treatment with S. terebinthifolius.
Abstract P latonia insignis M art., a native species of the B razilian A mazon more commonly known as bacuri, is member C lusiaceae family. In this study, we evaluated chemical composition and antioxidant toxicity activities dichloromethane ethyl acetate fractions from . seed ethanolic extract using different experimental models. Our results demonstrate in vitro effects, by 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulphonic acid) diammonium salt 1,1‐diphenyl‐2‐picryl‐hydrazyl assays, well...
The Irati Formation (Paraná Basin) is a mixed carbonate and organic-rich shale sequence intruded by Jurassic-Cretaceous basic rocks, featuring Brazil's most important oil deposits with different maturity levels. For the first time, distribution of biomarkers from an outcrop section (quarry) in northernmost Paraná Basin was analyzed GC-MS GC-MS/MS to determine thermal evolution, organic matter origin depositional paleoenvironment. at border basin has high similarity central southernmost...
ABSTRACT Protium heptaphyllum is found in the Amazon region, and various Brazilian states South American countries. Also Known as almecega, it produces an oil resin used traditional medicine analgesic, anti-inflammatory, cicatrizant expectorant, rich pentacyclic triterpenes essential oil. The main objective of this study was to analyze chemical composition P. heptaphyllumresin (OEPh) over different extraction times evaluate their antifungal activity against Candida species, obtained from...
Postbiotic is the term used to define soluble factors, metabolic products, or byproducts released by live probiotic bacteria after its lysis. The objective of this study was carry out chemical characterization postbiotic
The Protium heptaphyllum species, also known as Almécega, produces an oily resin, used in folk medicine analgesic and anti-inflammatory agent, healing, expectorant, which is rich pentacyclic triterpenes essential oils. In this study, the oil obtained by hydrodistillation of Almécega’s resin was analyzed gas chromatography-triple quadrupole mass spectrometry evaluated for chemical composition vasorelaxant activity rat superior mesenteric artery. main constituents determined were...
Diosgenin is a phytoestrogen and constituent of Dioscorea. It has several biological effects, some them are anti-inflammatory, antidiabetic, antitumor, vasodilatory. The present study investigated both the vasorelaxing antioxidant mechanisms diosgenin in isolated rat aortic rings. Female rats weighing 200-220 g were subjected to sham or OVX operations at 8 weeks age. Ovariectomy was performed for menopause induction after anesthesia. (10
The pantropical genus Bauhinia, Fabaceae, known popularly as cow's foot, is widely used in folk medicine antidiabetic. Behavioral effects of the ethanolic extract and ethereal, aqueous ethyl acetate fractions from B. platypetala Benth. ex Hemsl. leaves were studied male Swiss mice. administered intraperitoneally its on spontaneous motor activity (total motility, locomotion, rearing grooming behavior) monitored. Anxiolytic-like properties elevated plus-maze test possible antidepressant-like...
