Beekeeping directly depends on the floral biodiversity available to honey bees. In tropical regions, where nectar and pollen resources are numerous, botanical origin of some is still under discussion. A precise knowledge plants foraged by bees useful understand certify honey. this study, attention was paid samples from French Guiana Atlantic coast beekeepers generally place their hives in four types biotopes: seaside vegetation, mangrove, savannah, secondary forest. Pollen analysis 87...
Guiana is a little-known and endemic variety of cocoa (Theobroma cacao L.), native to French Guiana. No data were available regarding its chemical composition biological properties; therefore, study was necessary, using Forastero as reference. To exemplify activities the species, extracts evaluated by antioxidant (DPPH, FRAP, ORAC) anti-inflammatory assays. Our results showed that raw presented equivalent DPPH FRAP activities, but 1.3-fold higher activity (1097 ± 111.8 μM ET/g DM) than...
Various honeys from French Guiana were collected and analyzed to investigate their volatile fraction composition antioxidant activity. Volatile was assessed using HS-SPME/GC, GC-MS technique. Oxygenated monoterpenes like hotrienol (0.5-45.3%) found as major molecules, followed by non terpenic compounds phenylacetaldehyde (0.8-18.2%) or 3-hydroxy-4-phenyl-2-butanone (0.1-29.3%). Three chemical groups statistical analysis classified within investigated honey samples: norisoprenoids/shikimates,...
Polyphenols are a large group of structurally diverse natural products, including flavonoids. One the most bioactive compounds this class is flavonol quercetin, recognized antioxidant. Despite several studies were carried out aiming to develop nanoformulations with secondary metabolites, our knowledge, quercetin was not used as raw material for nanodispersion production without coating polymers. This type nanosize formulation often prepared using organic solvents and nanodispersions by...
Tapirira guianensis (Anacardiaceae) is a natural resource from the Amazonian Forest and locally known in French Guiana as "loussé" (creole), "tata pilili" (wayãpi), or "ara" (palikur). The tree used by indigenous populations for medicinal purposes. To increase potential of this cosmetic, agro-food, pharmaceutical uses, extracts were obtained through ultrasound-assisted extraction (UAE) T. leaves using various solvents such water, methanol, methanol-water (85/15; v/v). Chemical (DPPH, TEAC,...
