Abstract

Abstract:

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.

Key words: Trochus pyramis Born, pearl nacre powder, HCl-insoluble protein, trace chemical
