Alkali-lignin stimulated the degradation of sodium ascorbate in phosphate-buffered saline, fetal bovine serum and culture medium, but not in distilled water. ESR spectroscopy revealed that alkali-lignin stimulated ascorbyl radical production even in distilled water. Similar stimulation activity was found in several other plant extracts, commercial and natural lignified materials. These data suggest that the lignin-stimulated degradation process of ascorbate might be separated into two processes, the first being the ascorbyl radical production process and the second the degradation process.
碱木质素在磷酸盐缓冲盐水、胎牛血清和培养基中会促进抗坏血酸钠的降解，但在蒸馏水中不会。电子自旋共振光谱显示，即使在蒸馏水中，碱木质素也会促进抗坏血酸自由基的产生。在其他几种植物提取物、商业和天然木质化材料中也发现了类似的刺激活性。这些数据表明，木质素促进的抗坏血酸降解过程可能分为两个过程，第一个是抗坏血酸自由基产生过程，第二个是降解过程。
