摘要
为充分利用去肉后的马蹄螺贝壳资源,从塔形马蹄螺制得珍珠层粉,测定其微量有机物(二氯甲烷萃取)、酸不溶性蛋白质氨基酸组成及微量无机元素。结果表明:在二氯甲烷萃取物中共检测出13种成分,质谱数据库确定9种成分。从酸不溶蛋白质中检出18种氨基酸,含有人体所需的8种必需氨基酸;微量元素定量检测结果表明,马蹄螺珍珠层粉中含有人体所需的Mg、Fe、Zn、Se等微量无机元素,同时含有微量的As、Hg、Pb;半定量检测检出27种微量元素。因此,马蹄螺珍珠层粉是一种值得开发的资源。
Organic components in methylene dichloride fraction, amino acid in acid-insoluble fraction, and minerals in and inorganic elements in pearl nacre powder prepared from Trochus pyramis Born were investigated. GC-MS analysis showed the existence of 13 compounds in methylene dichloride fraction, and 9 compounds were identified. Totally 18 kinds amino acids, including 8 kinds essential amino acids, were found in the acid insoluble fractions by automatic amino acid analyzer. Inorganic elements, such as Mg, Fe, Zn, Se, as well as As, Hg, Pb were found and determined by using inductively coupled plasma mass spectrometry. The shell of Trochus pyramis Born is a resource worthy of development.
