“…In order to increase the resistance of wood to biotic conditions, various types of preservatives are used, and currently, preparations based on natural substances are becoming more and more popular, e.g., propolis extract [ 27 , 28 ]. The literature data confirmed that wood treated with propolis extract and a mixture of propolis extract and silicon compounds showed resistance to wood-decay fungi, including C. puteana [ 28 , 30 , 48 ]. In addition, wood used as a filler in wood composites are often modified or treated with preservatives to obtain resistance of WPCs against wood destructive microorganisms.…”

“…The stabilization of Xc results for systems containing modified wood can be explained by the protective effect of propolis. The activity of propolis against decay fungi has been studied and published many times [ 28 , 30 , 33 ]. There have also been many studies showing that propolis is a material capable of absorbing UV radiation [ 76 , 77 , 78 ].…”

“…However, legal regulations and the degradation of the natural environment lead to bio-friendly methods of wood treatment and modification being preferred. According to literature data, numerous natural substances or individual compounds isolated from them can be applied as potentially protective agents in bio-friendly wood protection, including natural oils, essential oils, plant extracts, chitosan, caffeine, or propolis [ 25 , 26 , 27 , 28 , 29 ]. Propolis is an interesting plant-derived material with broad antifungal activity, applied in wood protection.…”

“…Propolis is an interesting plant-derived material with broad antifungal activity, applied in wood protection. Wood treated with propolis extracts showed resistance against brown rot ( Coniophora puteana and Nelolentinus lepideus ) and white rot fungi ( Trametes versicolor ) [ 28 , 30 ]. In wood protection, propolis extract has also been used as a constituent of mixtures and was mixed with silver nanoparticles, chitosan, caffeine, and silicon compounds [ 30 , 31 , 32 , 33 ].…”

Bioactive Propolis-Silane System as Antifungal Agent in Lignocellulosic-Polymer Composites

Polymer composites with renewable lignocellulosic fillers, despite their many advantages, are susceptible to biodegradation, which is a major limitation in terms of external applications. The work uses an innovative hybrid propolis-silane modifier in order to simultaneously increase the resistance to fungal attack, as well as to ensure good interfacial adhesion of the filler–polymer matrix. Polypropylene composites with 30% pine wood content were obtained by extrusion and pressing. The samples were exposed to the fungi: white-rot fungus Coriolus versicolor, brown-rot fungus Coniophora puteana, and soft-rot fungus Chaetomium globosum for 8 weeks. Additionally, biological tests of samples that had been previously exposed to UV radiation were carried out, which allowed the determination of the influence of both factors on the surface destruction of composite materials. The X-ray diffraction, attenuated total reflectance–Fourier transform infrared spectroscopy, and mycological studies showed a significant effect of the modification of the lignocellulose filler with propolis on increasing the resistance to fungi. Such composites were characterized by no changes in the supermolecular structure and slight changes in the intensity of the bands characteristic of polysaccharides and lignin. In the case of systems containing pine wood that had not been modified with propolis, significant changes in the crystalline structure of polymer composites were noted, indicating the progress of decay processes. Moreover, the modification of the propolis-silane hybrid system wood resulted in the inhibition of photo- and biodegradation of WPC materials, as evidenced only by a slight deterioration in selected strength parameters. The applied innovative modifying system can therefore act as both an effective and ecological UV stabilizer, as well as an antifungal agent.

“…Propolis is a natural paste as a result of the accumulation of resinous substances collected from the bark, leaves and stems of the honey bees in the hives. This complex mixture, which is used to protect the hive for multiple purposes, is an indispensable natural bee product of apitherapy (Akçay, Birinci, Birinci, & Kolaylı, 2020;Bankova et al, 2019). It is known that the best solvent for raw propolis is 70% ethanol, but some glycol derivatives and vegetable oils are also usedin the preparation of extracts (González-Búrquez et al, 2018;Oroian, Ursachi, & Dranca, 2020).…”

In this study, quality parameters of some commercially sold in Turkey propolis extracts were compared with freshly prepared ethanolic propolis extract (70%). The pH, total phenolic substance, total flavonoid and total antioxidant capacity values of 11 different commercial samples, including aqueous, ethanolic, water-based and vegetable oil, were compared. As a result, it was determined that ethanolic samples had the highest activity and the activity of propolis with olive oil was very low. It was found that products with high total polyphenol content (TP) had high total antioxidant values. It was also determined that a standard method was not used for the preparation of commercial propolis samples and that the TP values differ greatly.
