“…Upon maceration, the plant material is immersed in a specific solvent at room temperature for a specified duration. [95][96][97] Pereira et al ( 2011) [54] quantified several secondary metabolites in the extract of powdered B. officinalis leaves, obtained using a solvent/plant material ratio of 50 : 1 (mL/g), agitation at 150 rpm, and a duration of 1 hour. The extract contained phenolic compounds (113.58 � 0.92 mg equivalent of gallic acid (GAE)/g of extract), anthocyanins (51.50 � 1.29 mg equivalent of malvidin 3-glucoside (ME)/g of extract), flavonoids (88.17 � 2.73 mg equivalent of catechin (CE)/g of extract), and flavanols (51.71 � 0.53 mg equivalent of quercetin (QE)/g of extract).…”

“…Although maceration is efficient for extracting bioactive molecules, the levels of secondary metabolites in Pereira et al (2011) study surpasses those of Zammouri et al (2019) and Conforti et al (2008), probably due to differences in extraction conditions such as solvent polarity, solvent/plant material ratio, agitation, the form of the plant material and extraction time. [95,97,98] The influence of these parameters is crucial, as the solvent or solvent mixture's polarity influences the solubility of the target compounds, while a high solvent/plant material ratio enhances efficiency compared to a low ratio. [95,98] Additionally, agitation is crucial in promoting homogenization and material transfer.…”

Borago officinalis L., an annual herb belonging to the Boraginaceae family, is used in the traditional medical practices of various countries and for multiple treatments, including respiratory disorders, colds, influenza, diarrhea, cramps, inflammation, palpitation, hypertension menopause, and post‐menopausal symptoms. Its pharmacological properties and biological activities ‐ among them antioxidant, antimicrobial, anticancer, anti‐inflammatory, insecticidal, antigenotoxic, and anti‐obesity activity ‐ were demonstrated in vitro and in vivo and are related to its rich content of bioactive compounds (mainly phenolic acids, flavonoids, anthocyanins, alkaloids, and terpenes) extracted from various parts of B. officinalis including leaves, flowers, seeds, and roots. This review summarizes all updated information on applied extraction processes, phytochemistry, pharmacology, and toxicity of B. officinalis.

“…Plant extracts are another group of plant derivatives that have been intensively developed as natural wood preservatives. The extracts are obtained from numerous plant species and from various plant parts including bark, leaves, fruits, flowers, buds, seeds, or wood [ 18 , 19 , 101 , 102 ]. Numerous plant extracts with biological activity have been used in the research on their possible application in environmentally friendly wood protection.…”

The biodegradation of wood and wood products caused by fungi is recognized as one of the most significant problems worldwide. To extend the service life of wood products, wood is treated with preservatives, often with inorganic compounds or synthetic pesticides that have a negative impact on the environment. Therefore, the development of new, environmentally friendly wood preservatives is being carried out in research centers around the world. The search for natural, plant, or animal derivatives as well as obtaining synthetic compounds that will be safe for humans and do not pollute the environment, while at the same time present biological activity is crucial in terms of environmental protection. The review paper presents information in the literature on the substances and chemical compounds of natural origin (plant and animal derivatives) and synthetic compounds with a low environmental impact, showing antifungal properties, used in research on the ecological protection of wood. The review includes literature reports on the potential application of various antifungal agents including plant extracts, alkaloids, essential oils and their components, propolis extract, chitosan, ionic liquids, silicon compounds, and nanoparticles as well as their combinations.

“…Needles contain vitamins, bioactive extractives (up to 43% of dry matter), and protein (about 10% of dry matter). , In fact, over 200 compounds have been identified from conifer sprouts and needles, and their chemistry has been found to differ from sap and heartwood compounds. − Especially, secondary metabolite-related extractives provide defense for the standing trees against different abiotic and biotic stressors, such as excessive humidity, drought, temperature variation, parasites, bacteria, fungi, and other phytopathogenic organisms . Thus, it is common for woody biomass extractives to possess antioxidant and antimicrobial properties, making them useful as preservatives in the food and cosmetic industries and holding potential for medicinal products . Even without considering the phenomenon of increased antibiotic-resistant pathogens, current antibiotics often cause adverse effects and have difficulties in safe dosing for various individuals .…”

During stemwood harvesting, substantial volumes of logging residues are produced as a side stream. Nevertheless, industrially feasible processing methods supporting their use for other than energy generation purposes are scarce. Thus, the present study focuses on biorefinery processing, employing response surface methodology to optimize the pressurized extraction of industrially assorted needle-rich spruce logging residues with four solvents. Eighteen experimental points, including eight center point replicates, were used to optimize the extraction temperature (40−135 °C) and time (10−70 min). The extraction optimization for water, water with Na 2 CO 3 + NaHSO 3 addition, and aqueous ethanol was performed using yield, total dissolved solids (TDS), antioxidant activity (FRAP, ORAC), antibacterial properties (E. coli, S. aureus), total phenolic content (TPC), condensed tannin content, and degree of polymerization. For limonene, evaluated responses were yield, TDS, antioxidant activity (CUPRAC, DPPH), and TPC. Desirability surfaces were created using the responses showing a coefficient of determination (R 2 ) > 0.7, statistical significance (p ≤ 0.05), precision > 4, and statistically insignificant lack-of-fit (p > 0.1). The optimal extraction conditions were 125 °C and 68 min for aqueous ethanol, 120 °C and 10 min for water, 111 °C and 49 min for water with Na 2 CO 3 + NaHSO 3 addition, and 134 °C and 41 min for limonene. The outcomes contribute insights to industrial logging residue utilization for value-added purposes.
