摘要
通过正交实验方法研究了艾叶醇-水体系的提取工艺,采用比色法测定其黄酮类和多糖类化合物的含量,得到不同因素对总黄酮和总多糖提取的影响程度依次为:乙醇浓度>提取温度>提取时间>料液比;并以化学发光法测定各提取液的抗氧化活性。结果表明;艾叶中含有丰富的黄酮类、多糖类化合物,具有很强的抗氧化活性。
In this paper orthogonal experiment method was used to study the extraction process in alcohol-water system of folium Artemisiae argyi. Its contents of total flavonoids and total polysaccharides were measured by colorimetry. And it was found that different factors impacting on extraction were as followed： the concentration of alcohol, extraction temperature, extraction time and the ratio of materials for extraction liquid. The anti-oxidant activities of the extraction liquid were also studied by the chemical luminescence method. Results showed that folium Artemisiae argyi contains abundant of flavonoid and polysaccharide, and its extract possesses strong anti-oxidant activity. Therefore the researh and development of folium Artemisiae argyi are of great significance.
