摘要: 本文研究了果蔬中叶酸的提取分离方法,对提取液、吸附剂及洗脱液设计了正交试验,结果是用热沸偏磷酸提取,活性炭吸附,3%氨-70%乙醇液洗脱,达到提取分离较完全之目的;并用荧光法测定叶酸含量,该方法回收率在95%以上,相对偏差小于2.5%,结果满意。
关键词: 叶酸, 荧光法, 提取分离, 吸附剂
Abstract: In this paper , the extracting and purifying technology of the folacin in fruits and vegetables was studied. We designedthe orthogonal test for the solvent, developing agent and sorbent. The results showed: extracted with hot boiling metaphosphoricacid , absorbed with active carbon, developed with the mixture solution of 3% ammonia and 70% anhudrous alcohol, the conclusiongained the ends of extraction and purifying comparative completeness. And we measured the content of folacin with thefluorescence spectrophotometer. The recovery ratio was beyond 95%, the relative deviation was below 2.5%. The results wassatisfied.
Key words: folacin, fluorescence analysis, extraction, purifying, sorbent
