江田昭英就用于抗过敏疾患的二十种生药,对其中有抗变态反应活性成分进行筛选,结果发现在这些生药中大枣乙醇对LgE抗体的产生有特异性抑制作用。并以抗过敏为指标,对大枣乙醇进行分析,结果分离出多种化合物,明确了它的结构。进而对这些化合物进行抗变态反应试验,已知道主要活性成分为乙基2果糖呋喃糖苷。在大枣中本来不含此种化合物,而是在乙醇提取过程中,大枣中的大量果糖在有机酸的作用下产生的。不过大枣的抗变态反应的活性物质还不仅仅是这一种,其余的正在研究中。还有,丁宗铁等发现,大枣中的CAMP浓度,为
Ezeki Eiji on the anti-allergy disorders for the twenty kinds of crude drugs, anti-allergic active ingredients were screened and found that these crude drugs in jujube ethanol LgE antibodies have a specific inhibitory effect. And anti-allergy as an indicator of jujube ethanol analysis, the results of the separation of a variety of compounds, clear its structure. These compounds were further tested for anti-allergic activity and it is known that the major active ingredient is ethyl 2 fructofuranoside. In the jujube did not contain such compounds, but in the ethanol extraction process, a large number of jujube fructose produced in the role of organic acids. However, anti-allergic jujube active substance is not only this one, the rest are being studied. Also, Dingzong Tie found that jujube CAMP concentration
