Shellfish shells sold as a crude drug in Taiwan are small in size (about 17-3Omm long) and appear whitish on the whole as the colour and patterns on shell surface have disappeared. Among those shells are the shells of the following seven species. 1) Erosaria erosa(h.), 2) E. helvola (L.), 3) Cribraria (s. s.) cribraria (L.), 4) Monetaria (Ornamentarid) annulus (L.), 5) Purpuradusta gracilis (GASKOIN), 6) Staphylaea (Nucleolaria) nucleus (L.), 7) Erronea (s. s.) cylindrica (Born). Those crude drug shells available in Hong Kong market include shells variable in size with clear colour and patterns on the surface: They appear comparatively fresh. Among those shells are those of the following six species. 1) Cypraea tigris L., 2) Erronea (s. s.) errones (L.), 3) Mauntia (Arabica) arabica (L.), 4) Monetaria (s. s.) moneta (L.), 5) M. (Ornamentaria) annulus (L.), 6) Ravitrona caputserpentis (L.). Quantity of total amino acid residues was extremely small in Monetaria {Ornamentarid) annulus (L.) both of Hong Kong (commercial sample A) and of Yoron Island (living sample B). (A 0.0059%, B 0.0120%). Almost all the amino acids commonly existing in organisms were detected in B. However, A devoids of some amino acids (Thr, Ser, Met, Tyr and Phe), which is probably due to the loss of the horny layer in A. In both A and B, the ratio of acidic amino acid residues to total amino acid residues was relatively high (over 50%). These acidic amino acid residues (Asp and Glu) probably play a very important role in binding and holding of calcium in shell.
