| Abstract [eng] |
After timber harvesting, approximately 30% of left unused the biomass consists of coniferous needles. However, through the extraction of valuable compounds such as proanthocyanidins (PA), phenolic compounds (PC), shikimic acid (SA), and others from these needles, we have the opportunity to purposefully utilise the by-products of forest biomass. Biologically active compounds like this, exhibit a broad spectrum of beneficial effects, including antioxidative, cardioprotective, antitumor, antibacterial, and antiviral effects [1,2,3]. This study focused on optimising the use of sustainable solvents for extraction process from coniferous needles through the application of Response Surface Methodology (RSM). Output data analysis was performed using analysis of variance (ANOVA). Aqueous extraction methods were selected to eliminate the need for additional solvent removal, thereby expanding the potential applications of the extracts. Using RSM, the process was optimised of produce for an extract with the highest concentration of bioactive compounds. In this investigation, was achieved a maximum SA concentration of 32.4 ± 0.1 mg/g of d.w., PC 79.21 ± 0.21 mg/g of d.w. and PA 45.70 ± 0.24 mg/g of d.w. These identified concentrations are considered sufficient to exhibit measurable antibacterial activity against food spoilage microbes and food pathogens, specifically Staphylococcus aureus and Bacillus cereus (see Fig.1), in the context for application of new food production [4].
