文摘The content of hydroxyproline of collagen sponge is tested by Woessner Method I.The hydroxyproline standard curve and regression equation are described.The content of hydroxyproline of collagen sponge is tested subsequently.The result show that the hydroxyproline content is consistent with that of collagen protein,which could be concluded that the purity of collagen sponge,either prepared in our institute or that from abroad is high.
