[Correlation analysis between nutritive components of Whitmania pigra and Bellamya purificata].
The dried Whitmania pigra is used for the treatment of cardiovascular and cerebrovascular diseases in traditional Chinese medicine. Bellamya purificata is widely distributed in the Chang Jiang River basin, it is natural diets of W. pigra. Current study was conducted to compare and analyze the nutritional ingredient in W. pigra, body fluid and flesh of B. purificata. Results showed that the contents of protein, crude fat and total sugar in W. pigra, body fluid and flesh of B. purificata were significantly different (P < 0.05). Protein content in W. pigra accounts up to 65.01%. The contents of inorganic elements and amino acid were abundant in W. pigra, body fluid and flesh of B. purificata. The content of essential amino acids in them were 32.6, 221.59, 40.78 mg x g(-1), respectively. The content of flavor amino acid in them were 27.51, 14.5, 32.03 mg x g(-1), while the coresponding content of antioxidant amino acid were 8.81, 5.91, 9.73 mg x g(-1), respectively. The individual amino acids of high content in them were Glu, Asp and Leu. Macro elements Ca, P, Mg and trace elements Zn, Si, Fe were abundant. It could be speculated that W. pigra may be a promising novel food, and the present results provide a foundation to develop artificial feed for W. Pigra.
