“…Turpentine is usually used as a paint thinner and varnishes or as a cleaning agent. Derivatives are widely used in fragrances and vitamins [ 26 ]. Synthetic pine oil used in disinfectants, cleaning agents, and other pine-scented products is the main derivative of turpentine [ 27 , 28 , 29 ].…”

Rosins and turpentines present in pine resins have been widely used both industrially (coatings, electronics and paint) and pharmaceuticals (ointments). Among the main components of these matrices is abietic acid. This study focuses on the characterization and evaluation of the quality of rosins and turpentines in addition to the quantification of abietic acid in rosins. Rosin and spirit of turpentine were obtained separately through the distillation method from P patula and P. oocarpa resin, species grown in the Department of Cauca-Colombia. Resin-tapping was made using the traditional method (cup and gutter). Quality indicators were determined according to ASTM standards. Solubility tests and identification of functional groups were performed on the obtained rosin by ultraviolet-visible spectroscopy (UV-Vis), infrared (IR) and nuclear magnetic resonance ( 1 H-NMR). The abietic acid present in the rosins was determined by high performance liquid chromatography (HPLC). According to their high acid value and low percentage of unsaponifiable matter, the extracted rosins are considered of medium-high quality. Quantification of abietic acid by HPLC showed 14.85 ± 0.24% and 16.09 ± 0.11% for P. patula and P. oocarpa rosin respectively.

“…The reactivity of carboxyl or amino groups on compound 1 (DHAA) or 4 (dehydroabietic amine) are low because of the steric hindrance of tricyclic phenanthrene skeleton of rosin. , Therefore, the preparation of rosin-based amides requires more harsh conditions, such as high temperature, high pressure, and the addition of catalysts. However, at higher temperatures, rosin is prone to decarboxylation or oxidation, resulting in darker color and more byproducts . Nonetheless, the reactivity can be greatly improved by converting carboxylic acid into active intermediates of acyl chloride.…”

In the current work, we synthesized two series of dehydroabietyl amide derivatives from natural product rosin and evaluated their antifungal effects on Valsa mali, Phytophthora capsici, Botrytis cinerea, Sclerotinia sclerotiorum, and Fusarium oxysporum. In vitro and in vivo antifungal activities results indicated that rosin-based amide compounds containing thiophene heterocycles had better inhibitory effects on B. cinerea. In particular, compound 5b (5-fluoro-2-thiophene dehydroabietyl amide) exhibited the excellent antifungal properties against B. cinerea with an EC 50 of 0.490 mg/L, which was lower compared to the positive control penthiopyrad (0.562 mg/L). Physiological and biochemical studies showed that the primary action mechanism of compound 5b on B. cinerea changes mycelial morphology, increases cell membrane permeability, and inhibits the TCA pathway in respiratory metabolism. Furthermore, QSAR and SAR studies revealed that charge distribution of rosin-based amides derivatives have a key role in the antifungal activity through the hydrogen bonding, conjugation, and electrostatic interaction between the compounds and the receptors of the target. To sum up, this study contributes to the development of rosin-based antifungal agents with a novel structure and preferable biological activity.

“…When oxidation times were in the range of 13–20 h, both the curves nearly showed a straight stepped line without any sharp change point. Cabaret et al have conducted the analysis of rosin heat treatment process under different conditions and found that the film formed on the rosin surface would prevent the inner rosin from further reaction, just like amber . While the oxidation temperature was about 448 K at the melting point of abietic acid in Figure a, a new oxygen consumption process occurred in Figure b.…”

“…Cabaret et al have conducted the analysis of rosin heat treatment process under different conditions and found that the film formed on the rosin surface would prevent the inner rosin from further reaction, just like amber. 48 While the oxidation temperature was about 448 K at the melting point of abietic acid in Figure 13a, a new oxygen consumption process occurred in Figure 13b. When abietic acid melted into a liquid, the viscosity value became so low that the oxidized film dissolved in the liquid-state abietic acid and continued consuming oxygen; then, the second oxidation stage occurred.…”

The thermal oxidation characteristics of abietic acid were investigated through tracing the oxidation process in custom-designed mini closed pressure vessel test under isothermal and step temperature conditions. Peroxide generation and the peroxide value of abietic acid oxidation process were measured using thin-layer chromatographic analysis and iodimetry. The primary oxidation productperoxidewas separated by column chromatography with further structure characterization, and its thermal decomposition characteristics were assessed via a differential scanning calorimeter (DSC). The oxidation was mainly initiated through the radical generation from hydrogen abstraction on the unsaturated conjugated double bonds of abietic acid above 343 K. The main hydroperoxide, 7-hydroperoxy-13-abiet-8(14)-enoic acid, was found in abietic acid with a high peroxide value. The exothermic onset temperature (T 0) and decomposition heat (Q DSC) of this peroxide were 353.94 K and 545.37 J·g–1, respectively. Finally, a second-stage oxidation process of abietic acid was first investigated when the temperature reached the abietic acid melt point (448 K) with complex oxidation products forming, such as dehydroabietic acid, palustric acid, 7-oxodehydroabietic acid, neoabietic acid, 7-methoxy-tetradehydroabietic acid, 12-deoxyroyleanone acid, and 12-methoxy-abietic acid.
