从松针中提取混合氨基酸方法研究

Research of Method on Extracting Mixed Amino-Acid From Pinus Mossoniana Lamb

报导从马尾松 (Pinusmossonianalamb)针叶中提取混合氨基酸的方法 .研究结果表明 ,方法Ⅰ和方法Ⅱ从马尾松针叶中提取 1 8种混合氨基酸 ,平均收率为1 0 - 1 4% ;用方法Ⅱ从马尾松针叶中提取 1 8种氨基酸的总量是用方法Ⅰ从同量松针叶中提取 1 8种氨基酸的总量的 1 5倍以上 .

Discuss two methods of extracting mixed amino-acid from pinus mossoniana lamb.The result indicats that both methods can extract 18 Classes of amino-acid from the said material above with average extraction rate being 10-14%,and the amount of extracted amino acid by method Ⅱ is 1.5 times more than that by methodⅠ.
