摘要
本文采用生物化学研究方法，采用弱酸去钙法成功除去无机成分碳酸钙，并保留完整的有机大分子，运用红外吸收光谱（IR）对其进行分析检测，结果显示：珍珠有机质具有特定的IR图谱，且珍珠有机质可分为可溶有机质和不可溶有机质，可溶有机质在3298cm^-1，1658cm^-1，1547cm^-1，1534cm^-1等处有特征吸收峰，表明可溶有机质主要是蛋白质和色素分子形成的复合物，不可溶有机质在3281cm^-1，1655cm^-1，1524cm^-1等处有较强吸收峰，表明不可溶有机质主要是壳角蛋白。
The pearl of Hyriopsis cwrdagii（Lea） ,is a biomineral product of approximately 95% CaCO3 crystals and a matrix of biological macromolecules. Despite constituting less than 5% of total pearl weight,matrix controls the form and quality of pearl. By use of biochemical research method, CaCO3 was dissolved by weak acid, and the complete matrix macromolocules were kept. IR was used to study the matrix, and the results indicated. The pearl showed specific Infi＇ared Spoctroacopy and the matrix was made up of water soluble matrix and water insoluble matrix. The peak of IR spectra of water soluble matrix appeared at 3298cm^-1, 1658cm^-1, 1547cm^-1, 1534 cm^-1 etc and those of water insoluble matrix at 3281cm^-1, 1655 cm^-1, 1524cm^-1,ctc. This indicated that water soluble matrix contained mainly protein macromolocules and pigment organic molecules, and water insoluble matrix contained mainly protein macromolocules.
