Objective: To analyze the content of proteins,amino acids and inorganic elements of Holotrichia diomphalia in different growing areas as the references for quality evaluation and reasonable application of them.
Methods: The contents of proteins were determined using semi-micro Kjeldahl method. The contents of seventeen amino acids and inorganic elements were determined with amino acid analyzer and atomic absorption spectrometer and elemental analyzer, respectively.
Results: The contents of protein were 33.4%-44.4%, and that in Jiangxi were the highest in five different areas. There were seventeen kinds of amino acids in Holotrichia diomphalia. Among them, seven amino acids were essential to human life. The content of glutamic acid was the highest in seventeen amino acids. In inorganic elements, the content of Mg, Ca was higher in macroelements and Fe, Zn was higher in microelements.
Conclusion: There are many kinds of necessary amino acids and inorganic elements for man kind in Holotrichia diomphalia. The contents of proteins, amino acids and inorganic elements have some difference in Holotrichia diomphalia of different growing areas.
