Microalgae are promising alternative sources of several bioactive compounds that useful for human applications. However, lipids traditionally extracted with toxic organic solvents (e.g., mixtures chloroform and methanol or hexane). In this work, we develop a new lipid extraction protocol obtaining fatty-acids-rich extract from the diatom Phaeodactylum tricornutum. Deep eutectic (DESs) microwaves (MWs) were investigated as pretreatments environmentally friendly solvent extractions using...
This study reports on the biological properties, antioxidant and antidiabetic, of two varieties Amaranthus caudatus seeds, Oscar blanco Victor red. Oil, squalene phenolic contents were also determined. Seeds both investigated found to possess very different levels (2.2% in variety 7.5% red variety). Although activity A. var. statistically did not differ significantly from each other (IC50 values ethyl acetate extracts 0.50 mg/ml 0.62 mg/ml, respectively), significant differences noticed...
Wild Amazonian basil Ocimum micranthum Willd. (O. campechianum Mill.) Labiatae essential oil was analyzed by GC and GC-MS: 31 compounds were identified. The main components eugenol (46.55 ± 5.11%), β-caryophyllene (11.94 1.31%), β-elemene (9.06 0.99%), while a small amount of linalool (1.49 0.16%) detected. tested for its in vitro food-related biological activities compared with common basilicum Thymus vulgaris commercial oils. Radical scavenging activity evaluated employing...
Fourteen brands of resveratrol-containing nutraceuticals were evaluated in order to verify their actual resveratrol content and control if health-promoting properties are related manufacturing quality. Products included pure capsules or multi-ingredient formulations with standardized amounts other phytochemicals. Samples analyzed for total trans-resveratrol, flavonoids, procyanidin, polyphenol the results compared declared on-label. Only five out 14 had near label values, compliant Good...
Aedes aegypti , the main arbovirus vector of Yellow fever, Dengue, Chikungunya and Zika viruses, is widely distributed in tropical subtropical areas throughout world. Preventive control efforts have been implemented worldwide aimed at reducing its impact on human health. The recent reduction chemicals available for due to their negative environment health increase mosquito resistance insecticides driven research community identify evaluate sustainable alternatives synthetic insecticides. In...
A pharmacognostic survey of 84 commercial samples Mediterranean oregano, obtained from wholesale traders between 2001 and 2007, pinpointed the presence extraneous plant material in 90.5% samples. In 59% them origin was above 20%. Two major groups botanical foreign matter were identified: oregano-like flavored plants (Satureja montana L., Origanum majorana L.) lacking a clearly detectable essential oil profile (Rubus sp., Cistus incanus Rhus coriaria L.), added as bulk material. random...
This study describes the preparation, characterisation and in vitro activity of nanostructured lipid carriers (NLCs) encapsulating natural molecules with antimicrobial activity, such as plumbagin, hydroquinon, eugenol, alpha-asarone alpha-tocopherol. NLCs were prepared by melt ultrasonication method, characterised Cryo-TEM for morphology SdFFF dimensional distribution active encapsulation yields. In tests conducted on bacteria, fungi human cell cultures. demonstrated that plumbagin is...
In this study, we performed the chemical characterization of Myrcia splendens (Sw.) DC. (Myrtaceae) essential oil from Amazonian Ecuador and assessment its bioactivity in terms cytotoxic, antibacterial, antioxidant activity as starting point for possible applicative uses. M. oil, obtained by hydro-distillation, was analyzed Gas Chromatography-Mass Spectrometry (GC-MS) Chromatography-Flame Ionization Detector (GC-FID): major components were found to be trans-nerolidol (67.81%) α-bisabolol...
The chemical composition and biological activity of essential oils isolated from the leaves Siparuna aspera, macrotepala, Piper leticianum, augustum rhizome Hedychium coronarium were evaluated. These species are used medicinally in different ways by Amazonian communities that live near Kutukú mountain range. Chemical studies revealed main components for two germacrene D, bicyclogermacrene, α-pinene, δ-cadinene, δ-elemene, α-copaene β-caryophyllene; β-caryophyllene, α-(E,E)-farnesene,...
Essential oils (EOs) and their vapour phase of Curcuma longa (Zingiberaceae), Cymbopogon citratus (Poaceae), Ocimum campechianum (Lamiaceae), Zingiber officinale (Zingiberaceae) cultivated plants grown in an Amazonian Ecuador area were chemically characterised by Gas Chromatography-Flame Ionization Detector (GC-FID), Chromatography–Mass Spectrometry (GC-MS), Head Space–Gas Chromatograph-Flame Detector–Mass (HS-GC-FID-MS).figure The EOs analyses led to the identification 25 compounds for C....
