For desertification expansion,the relative role of climate change was more obvious,which was mainly attributed to the continuous reduction in precipitation in eastern IMGW, and the increase in grassland use intensity was the main factor underlying regional human-induced desertification expansion.

Previous studies have suggested that polypeptides extracted from milk, soybean, fish, eggs, and meat possess potential anti-inflammatory effects. To date, few studies have reported the anti-inflammatory function of sturgeon peptides and their underlying mechanisms are unknown. The current study was therefore to determine the anti-inflammatory potential of sturgeon peptides with lipopolysaccharide (LPS)-induced RAW264.7 inflammatory model. Pepsin hydrolysate (PeH) was purified by ultrafiltration and Sephadex G-15 gel filtration chromatography. PeH significantly reduced the inflammatory mediator (NO) and inflammatory cytokines (IL-6, TNF-α and IL-1β) expression in a dose-dependent manner. Moreover, the purified sturgeon peptide (F2) possessed strong antioxidant potential and effectively inhibited DPPH and ABTS free radicals. F2 significantly suppressed the expression of MAPK, IκBα, and NF-κB p65, indicating that F2 exerted anti-inflammatory influence by the inhibition of MAPK and NF-κB pathways.

为了充分提取和利用高生物活性的天然左旋多巴(L-DOPA),研究了超声波强化提取发芽蚕豆L-DOPA的工艺条件,并初步探讨了超声浸提动力学过程。基于单因素试验,以超声功率、液固比、萃取时间为考察因素,采用Box-Behnken试验设计进行了工艺参数优化,结果表明,超声功率对发芽蚕豆L-DOPA得率的影响较大;原料用量2.0g,采用含30%乙醇的0.1mol/L醋酸溶液为提取溶剂,其较佳提取工艺条件为:超声功率257W、液固比31mL/g、萃取时间为37.4min。在此条件下,发芽蚕豆L-DOPA的平均得率为1.47%,较未发芽蚕豆增加0.58倍,略高于传统提取法,且超声强化提取显著缩短了浸提时间。对最优提取条件下L-DOPA得率随时间变化的动力学分别用Film模型、非稳态扩散理论和Ponomaryov经验方程进行拟合,其中Film理论模型的拟合度较好,其决定系数R2值最大,为0.9928。研究结果为天然L-DOPA制备提供了参考。
