Lignin, the most abundant aromatic biopolymer on Earth, has great potential to replace petrochemical-based polymers in production of value-added products. However, lignin is difficult extract from lignocellulose because recalcitrance latter. Herein, extraction using deep eutectic-like solvents (DESs) as green was investigated. Three types DESs were used, and effects treatment temperature (100, ...

Oxidative stress is considered to be a mechanism of major depression. Pycnogenol (PYC) is a natural plant extract from the bark of Pinus pinaster Aiton and has potent antioxidant activities. We studied the ameliorative effect of PYC on depression-like behavior in chronic corticosterone- (CORT-) treated mice for 20 days. After the end of the CORT treatment period, PYC (0.2 mg/mL) was orally admi...

Forests have the largest terrestrial nutrient pools. The loss of soil carbon and nitrogen in forests under ongoing climate warming is subject to severe environmental degradation. To mitigate negative effects global on forest, it important obtain a better understanding how elevated temperature altered precipitation variability impact dynamics. explore such interactions, we coupled an eco-hydrolo...

The natural range of shortleaf pine encompasses 22 states from New York to Texas, second only to eastern white pine in the eastern United States. It is a species of minor and varying occurrence in most of these states usually found in association with other pines, but it is the only naturally occurring pine in the northwestern part of its range in Oklahoma, Arkansas, and Missouri. Over the whol...

Low-acid hydrothermal (LAH) fractionation conditions were optimized for the effective degradation of hemicellulose from pine wood (Pinus densiflora). The hemicellulosic sugar yield was maximized at 82.5% when fractionated 190 °C, with 0.5 wt.% sulfuric acid, and 10 min. Consecutively, acidified heat treatment zinc chloride solvent extraction ethyl acetate carried out recovery bio-based platform...
