Extraction and utilization of dimethyl-β-propiothetin from chinese cabbage

In this paper we dealt with extraction and utilization of fish growth stimulator from chinese cabbage. The extractive content of dimethyl-β-propiothetin(DMPT) in chinese cabbage was 294,300ng/g during autoclaving at 121℃ for 45 minutes. A rate of growth in the red sea bream, experimental fish fed the diet added curde DMPT showed a high rate of growth than the control. Feed efficiency showed highest as 83.91% at the diet added 200㎖/kg(crude DMPT/total diet) than the control(65.76%) and a rate of growth was highest at the diet added 100㎖/kg(crude DMPT/total diet). In the Takifugu obscurus, also, a rate of growth was high as 201.7% at the diet added 100㎖/kg(crude DMPT/total diet) than of control(199.1%). The muscle composition of experimental fish fed crude DMPT from chinese cabbage as follows : to increasing of crude protein but to be decreasing of moisture, crude lipid and crude ash. Components of amino acid after 12 weeks of feeding trial ; glutamic acid, aspartic acid, alanine, lysine, glycine, leucine and serine were high but cystine. histidine and tyrosine were low. 18:1n-(7+9), 18:2n-6, 22:6n-3, 20:4n-6 and 16:1n-7 of fatty acid were commonly the major fatty acid in muscle composition of experimental fish fed crude DMPT from chinese cabbage.
