Acetohydroxamic acid ( AHA) is synthesized by the method of hydrochloric hydroxylamine reaction with acetic ether in alcohol water medium and its structure is characterized by element analysis, IR, MS, et al. 在乙醇水体系中,用乙酸乙酯和盐酸羟胺为主要原料合成了乙异羟肟酸(AHA),并通过元素分析、红外光谱(IR)、质谱(MS)等方法对其结构进行了表征。
In the extracting study, it has showed hydrochloric acid-heat treatment is a simple, convenient and effective extracting methods is which was used to destroy the cell wall, and the extracting organic solvent is petroleum ether whose boiling range is 60~ 90 ℃. 研究中还找到一个简便有效的对β-胡萝卜素的提取方法,选用盐酸-热处理法进行细胞破壁,并选用沸程为60~90℃的石油醚进行萃取。
