求翻译：本文采用的方法是硫酸-苯酚法[33] 检测总糖含量，多糖在浓硫酸作用下，水解生成 单糖，并迅速脱水生成糠醛衍生物，然后与苯酚缩合成橙黄色化合物，且颜色稳定，在 波长 490nm 处有最大吸收，其吸光度与总糖含量成线性关系，因此，可以利用分光光度 法测定其吸光度，并利用外标法定量。是什么意思？

This approach is sulfuric acid - phenol method [33] detected the total sugar content of polysaccharides in concentrated sulfuric acid, the hydrolysis of simple sugars and rapidly dehydrated to furfural derivatives, and phenol condense with orange-yellow compound, and the color stability, at a wavele
