微量醋酸提取黄连中黄连素及其含量测定

To Extract of Berberine from Rhizoma Coptidis and Its Content Determination with Trace Amounts of Acetic Acid

利用微量醋酸通过不锈钢锅提取黄连中的黄连素,并用重量法、氧化还原法和蒸馏法测结晶水等方法来测定黄连素的含量.实验发现,该方法是提取黄连素比较理想的,用氧化还原法测定黄连素的含量可行性比较高.

In the paper, the author extracted berberine from rhizoma coptidisusing through the stainless steel pot with the trace of acetic acid, and determined the content of berberine respectively measured by weight method, oxidation-reduction method and distil- lation methods for water of crystallization. The experimental results show that the method is an ideal way for extracting berberine, and the method of oxidation reduction is more feasible.
