侧柏叶有效成分提取过程研究

研究了侧柏叶有效成分酶法提取及乙醇－水混合溶剂提取过程。用测定电导率及标定有效成分含量方法反映提取规律。对提取过程中的温度、ｐＨ值、酶用量、提取时间、乙醇浓度及侧柏叶粒度等工艺条件进行了实验研究，得到优化的提取条件。提出在理论上用溶解度参数法选择提取剂及其浓度，实验结果证实与理论一致。

Study on Extracting Process of Effective Components from Cacumen Biotae

Using　enzyme　and　mixed　solvent　composed　of　alcohol　and　water,two　processes　of　extracting　effective　components　from　Cacumen　Biotae　are　studied.The　mass　transfer　regularity　is　reflected　by　measuring　specific　conductance　and　content　of　effective　components.The　extracting　conditions　such　as　temperature,pH,enzyme　consumption,time,mixed　solvent　etc.are　investigated　and　the　optimal　results　were　obtained.It　is　proposed　that　the　extractant　and　its　concentration　should　be　chosen　theoretically　in　terms　of　solubility　parameters,the　results　of　experiment　coincides　with　its　theoretical　value.
