“…In general, the bioactive properties (as antioxidant) of the natural resources, in our case of pine bark, may differ from plant to plant due to a number of environmental factors such as the level of maturity, the growing conditions (location, soil status, climate, and agricultural practices), and also the conditions of storage of postharvest material (temperature, time, humidity, presence of contaminants, etc.). 34 The different methods used for determination of antioxidant activity allows different mechanisms of action of extracts to be evaluated. The FRAP method is based on the reduction of a Fe 3+ complex to Fe 2+ , confirming the presence of reducing antioxidants.…”

Pinus pinaster (pine) bark is a widely available wood industry byproduct but an underexploited source of phenolic compounds with a strong antioxidant activity. The aim of this study was to evaluate the effectiveness of ohmic heating (OH, a recognized eco-friendly, electric fields-based processing technology) for the sustainable recovery of phenolic compounds from Pinus pinaster bark. Results of OH evidenced increased extraction of antioxidant phenolic compounds with no degradation of pine bark extracts for all tested conditions. Moreover, the enhancement in phenolic content in OH-assisted extraction was particularly evident when using a hydroethanolic solvent with 50% ethanol, reaching improvements higher than 100%, when comparing to the conventional approach. This fact may indicate preferential extraction, presumably due to the action of electric field effects acting in synergy with heat and solvents. Furthermore, additional changes in the morphological structure of bark cells were observed upon OH-assisted extraction, suggesting membrane electroporation effects. A significant reduction in energy consumption when compared with the conventional process was observed, leading to an energetically more sustainable approach. OH technology holds the potential to be a "green" alternative, with higher extraction yields and reduced energy consumption and offering the possibility of tuning the selectivity toward phenolic compounds.

Introduction:Ever since ancient times, medicinal plants recognized as major source of therapeutics, as rescue for human diseases and maintain health. There is an exponential increase in usage of green medicines due to less cost and fewer side effects. The family Pinaceae, is largest conifer in species diversity. Pinus is the largest genus of monoecious, resiniferous, evergreen trees commonly known as Pines. Three species of pines occur wild in Indian Himalayas Pinus roxburghii, Pinus wallichiana , Pinus gerardiana. In addition, the constituents present in these plants are beneficial for the purpose of treatment of various ailments. Methods: Information was collected from scientific journals, books, and reports via electronic search tools( Medline, Pubmed etc.) Results: This review summarizes the existing information on three species of Pinus in relation to their pharmacognostic properties, phytochemistry, ethanopharmacology and pharmacological activities.

“…MP‐AA/W showed the lowest ORAC and PSC (Table ). Whereas water extract of Chilgoza powder exhibited a strong antioxidant activity when compared to pure dichloromethane, ethanol, ethyl acetate, hexane and methanol extract (Hoon et al ., ). These references indicated that change in solvent type and polarity might significantly influence the antioxidant activity of obtained extracts.…”

Summary A systematic study about the solvent effect on the mulberry polyphenol (MP) profile, antioxidant and antiproliferation capacities against human hepatoma HepG2 cells was conducted. Results indicated that MP profiles showed significant differences as a function of solvents including AA/W (acetic acid/water), MeOH/AA/W (methanol/ acetic acid/water), EtOH/AA/W (ethanol/ acetic acid/water) and ME2CO/AA/W (acetone/ acetic acid/water). Among the solvents, EtOH/AA/W took advantage in obtaining MP with the highest yield (49.81 mg GAE g−1 dw), and cellular antioxidant capacity in the PBS no‐wash protocol (63.2 μmolQE/100 g), as well as low cell cytotoxicity (≥50.0 mg mL−1). ME2CO/AA/W was the best choice for extracting MP with the most various compositions (two phenolic acids, four anthocyanins and four flavonols), greatest potential in inhibiting proliferation of HepG2 cells (EC50 = 28.2 mg mL−1) and highest intracellular antioxidant activity (38.0 μmolQE/100 g). Results provide baseline information for efficient solvent extraction to obtain MP that is promising as natural antioxidants and antitumor agents.
