Methods: DECB was dealed with heat , acid , alkali , roasting , organic solvent extracting , microorganism zymolysis , then the method of microrespiromete was used to detect/measure the respiratory activity respectively.

目的：研究小牛血清去蛋白提取物（deproteinated extract of calf blood，DECB）中生物活性物质的物理化学性质；方法：分别将小牛血清去蛋白提取物进行加热、加酸、加碱、烘烤、有机溶剂萃取、接种微生物发酵等方法处理，然后分别用微量呼吸检压法检测呼吸活性，结果：采用加热、加碱、加酸，接种微生物发酵的方法进行处理，DECB刺激呼吸活性的能力没有明显改变，而采用烘烤的方法处理，结果DECB的活性完全消失；用有机溶剂萃取DECB，可明显降低DECB刺激呼吸活性的能力，而有机相中含有了刺激呼吸活性物质。
