520 | |a Abstract The geopropolis produced by the stingless bee Melipona subnitida (popularly called “jandaíra” in Brazil) is a mixture of resin, wax, and mud. This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formulation and their chemical profile by UHPLC-PDA-qTOF-MS/MS. Three different gels were prepared using the geopropolis extract, carbomer, propylene glycol, and water. Formulations with different amounts of propylene glycol were investigated. Physical, visual, pH, viscosity, adhesion, spreadability, leakage, and in vitro release tests were performed in the proposed formulations. Antifungal tests with the geopropolis ethanolic extract were carried out against six Candida species. The chemical profile of the geopropolis extract and compounds released from the formulations were analyzed after the release test. The formulations had a pH between 4.6 and 4.8 and viscosity between 535,600 and 920,400 cPs. The geopropolis extract presented excellent antifungal activity against the tested yeasts. The results of the release test in semipermeable cellulose membrane showed that all formulations containing 5%, 10% and 40% propylene glycol presented release of geopropolis extract. For adhesion and leakage tests, the gel formulation with 5% propylene glycol was more effective. Both geopropolis ethanolic extract and the liquid obtained in the release test showed the presence of flavonoids (flavonol/flavone, flavanone, and chalcones). Gel formulations with geopropolis extract that are rich in flavonoids are promising as an adjuvant treatment of vaginal candidiasis. | ||

This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formulation and their chemical profile by UHPLC-PDA-qTOF-MS/MS. Three different gels were prepared using the geopropolis extract, carbomer, propylene glycol, and water. Formulations with different amounts of propylene glycol were investigated. Physical, visual, pH, viscosity, adhesion, spreadability, leakage, and in vitro release tests were performed in the proposed formulations. Antifungal tests with the geopropolis ethanolic extract were carried out against six Candida species. The chemical profile of the geopropolis extract and compounds released from the formulations were analyzed after the release test. The formulations had a pH between 4.6 and 4.8 and viscosity between 535,600 and 920,400 cPs. The geopropolis extract presented excellent antifungal activity against the tested yeasts. The results of the release test in semipermeable cellulose membrane showed that all formulations containing 5%, 10% and 40% propylene glycol presented release of geopropolis extract. For adhesion and leakage tests, the gel formulation with 5% propylene glycol was more effective. Both geopropolis ethanolic extract and the liquid obtained in the release test showed the presence of flavonoids (flavonol/flavone, flavanone, and chalcones). Gel formulations with geopropolis extract that are rich in flavonoids are promising as an adjuvant treatment of vaginal candidiasis.

abstract |
Abstract The geopropolis produced by the stingless bee Melipona subnitida (popularly called “jandaíra” in Brazil) is a mixture of resin, wax, and mud. This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formulation and their chemical profile by UHPLC-PDA-qTOF-MS/MS. Three different gels were prepared using the geopropolis extract, carbomer, propylene glycol, and water. Formulations with different amounts of propylene glycol were investigated. Physical, visual, pH, viscosity, adhesion, spreadability, leakage, and in vitro release tests were performed in the proposed formulations. Antifungal tests with the geopropolis ethanolic extract were carried out against six Candida species. The chemical profile of the geopropolis extract and compounds released from the formulations were analyzed after the release test. The formulations had a pH between 4.6 and 4.8 and viscosity between 535,600 and 920,400 cPs. The geopropolis extract presented excellent antifungal activity against the tested yeasts. The results of the release test in semipermeable cellulose membrane showed that all formulations containing 5%, 10% and 40% propylene glycol presented release of geopropolis extract. For adhesion and leakage tests, the gel formulation with 5% propylene glycol was more effective. Both geopropolis ethanolic extract and the liquid obtained in the release test showed the presence of flavonoids (flavonol/flavone, flavanone, and chalcones). Gel formulations with geopropolis extract that are rich in flavonoids are promising as an adjuvant treatment of vaginal candidiasis. |

Abstract The geopropolis produced by the stingless bee Melipona subnitida (popularly called “jandaíra” in Brazil) is a mixture of resin, wax, and mud. This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formulation and their chemical profile by UHPLC-PDA-qTOF-MS/MS. Three different gels were prepared using the geopropolis extract, carbomer, propylene glycol, and water. Formulations with different amounts of propylene glycol were investigated. Physical, visual, pH, viscosity, adhesion, spreadability, leakage, and in vitro release tests were performed in the proposed formulations. Antifungal tests with the geopropolis ethanolic extract were carried out against six Candida species. The chemical profile of the geopropolis extract and compounds released from the formulations were analyzed after the release test. The formulations had a pH between 4.6 and 4.8 and viscosity between 535,600 and 920,400 cPs. The geopropolis extract presented excellent antifungal activity against the tested yeasts.
