Analysing chemical composition and antimicrobial activity of geopropolis from Melipona scutellaris: HPLC-DAD and in vitro/in silico investigations.
This study evaluated the chemical profile, antimicrobial activity, and the presence of potentially toxic elements in geopropolis extracts produced by Melipona scutellaris in the Recôncavo region of Bahia, Brazil. It was found that the major chemical compounds belong to the class of phenolic compounds, with emphasis on the presence of gallic acid. In this study, no potentially toxic elements were found in the analysed geopropolis. Regarding the antimicrobial potential, gram-positive bacteria were susceptible to the action of geopropolis extract at concentrations of 0.25 to 2.5 mg.mL-1, highlighting its microbiological activity against Streptococcus mitis (ATCC 00456) and Candida albicans (CCMB 251). Thus, this geopropolis extract can be used as a bacteriostatic rather than a bactericide. Our results suggest the potential for the economic and therapeutic use of M. scutellaris geopropolis, adding value to one of the meliponiculture products.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
