摘要
A systematically comparative study on the contents of vitamins in the natural and the cultured prawn, Penaeus chinensis, was made by using High-efficiency Liquid Phase Chromatography in 1989. The results show that the vitamin C (Vc) content in the natural prawn was 8. 19% higher than that of the cultured prawn.As the natural prawn's body length increasing, the Vc content in cephalothorax increased continuously, but after August 10, the Vc content in the cultured prawn fell down rapidly. No significant differences in vitamin B1, B2,B6, nicotinic acid (NAc), nicotinamide (NAm) and folio acid (FAc) were found between the natural and the cultured prawn. Therefore, Vc probably is one of major factors limiting the growth and development of Chinese prawn.
