“…These alkaloids have the potential to prevent the onset of various degenerative diseases by scavenging free radicals or binding with the oxidative reaction catalysts. Aqueous extracts of coniferous needles have been found to contain piperidine alkaloids, specifically α-pipecoline (34), cispinidine (35), and others [60,83,84].…”

“…The efficiency of the biorefinery is also influenced by factors such as the intensity of biomass disintegration, drying methods, and the use of wet biomass. Several studies have examined the changes in the chemical composition of coniferous needle/greenery biomass, including the analysis of seasonal variation in needle composition and the effect of tree age [84,85]. The concentrations of carbohydrates and amino acids are found to be the most sensitive to seasonal changes, while lipids, fatty acids, and resin acids exhibit greater resistance to such variations.…”

“…It possesses several advantageous properties, including the ability to extract lowerpolarity substances, cost-effectiveness, favourable recycling possibilities, and high overall extraction capacity [122]. Using iso-propanol as the extractant, extracts can be obtained from needles/greenery with yields up to 35% of the dry mass [84]. Considering the high number of substances that can be extracted with isopropanol, subsequent fractionation steps are necessary to obtain groups of substances with high application potential for various industries.…”

“…Furthermore, the neutral substances can be saponified using 35% NaOH, and after acidification, chlorophyllin can be isolated (Figure 2). Chromatographic fractionation can be employed to isolate a high number of terpenes, as well as individual resin acids, from the extracts [84]. A more simplified approach for processing iso-propanol extracts was suggested by Troshina and Roschin (2014).…”

Sustainable development goals require a reduction in the existing heavy reliance on fossil resources. Forestry can be considered a key resource for the bioeconomy, providing timber, energy, chemicals (including fine chemicals), and various other products. Besides the main product, timber, forestry generates significant amounts of different biomass side streams. Considering the unique and highly complex chemical composition of coniferous needle/greenery biomass, biorefinery strategies can be considered as prospective possibilities to address top segments of the bio-based value pyramid, addressing coniferous biomass side streams as a source of diverse chemical substances with applications as the replacement of fossil material-based chemicals, building blocks, food, and feed and applications as fine chemicals. This study reviews biorefinery methods for coniferous tree forestry biomass side streams, exploring the production of value-added products. Additionally, it discusses the potential for developing further biorefinery strategies to obtain products with enhanced value.
