Concentrated bud macerates (CBMs) are obtained from meristematic tissues such as buds and young shoots by maceration in a solvent composed of glycerin, water ethanol (1/1/1/, v/v). Their traditional utilization gemmotherapy has gained interest the past years, knowledge their chemical characterization can provide commercial arguments, particularly to secure quality control. Therefore, an optimized method for phytochemical analysis including glycerol removal preliminary solid phase extraction...
A new C15-acetogenin, sagonenyne (20), exhibiting an unusual single tetrahydropyran ring was isolated from ethyl acetate extract of Laurencia obtusa collected on the Corsican coastline. Its structure established by detailed NMR spectroscopic analysis, mass spectrometry, and comparison with literature data. Twenty-three known compounds were identified in same means column chromatography steps, using a 13C-NMR computer aided method developed our laboratory. In addition to sesquiterpenes, which...
The chemical investigation of an ethyl acetate extract (EtOAc) obtained from Laurencia obtusa, collected in Corsica, allowed for the identification three new compounds (1, 2, and 4) six known compounds. Compounds 1 to 4 were isolated fully characterized by a detailed spectroscopic analysis. 2 are two C15-acetogenins sharing same ring system: tetrahydropyran linked methylene tetrahydrofuran ring. Compound exhibits bromoallene unit whereas compound possesses uncommon α-bromo-α,β-unsaturated...
Generic and specific determination among the Laurencia complex is a challenging task. DNA barcoding combined with phenotypic investigations are mandatory for species differentiation. In this study, two morphologically different members of were investigated using untargeted 1 H-NMR-based metabolomics. Twenty-one population samples collected in order to evaluate both temporal geographical homogeneity. Data obtained from H-NMR analysis followed by statistical allowed clear separation all into...
Gemmotherapy, a natural therapy based on bud macerates, has recently gained importance in the field of food supplements. However, two coexisting extraction methods employ glycerin-based solvent, either binary or ternary solvent mixture. The absence an official method for preparation leads to non-standardized macerates. Given this context, study aimed (i) assess influence composition chemical profile olive young shoot macerates obtained using solvents different extractions and (ii) compare...
