四种山蓝加工方法的比较

用高效液相色谱法和分光光度法测定了四种加工方法所得山蓝加工提取物中有效成分含量 ,结果表明 ,经阴干 ,晒干 ,乙醇浸泡几种传统加工方法加工的山蓝中紫蓝素含量分别为 31 1、4 5 6、4 72 mg/1 0 0 g(干重 ) ,而采用避氧热处理加工的山蓝中 ,紫蓝素含量达 1 .73g/1 0 0 g。用传统加工方法对山蓝进行加工 ,有效成分含量低 ,制约了山蓝的利用价值 ,而避氧热处理能大大提高有效成分含量 ,提升山蓝的品质。研究结果对山蓝的加工、炮制和开发利用有重大意义。

The comparison of four methods for processing Peristrophe baphica

The content of the effective component,Zilanine,in Peristrophe baphica processed by four methods was measured by HPLC and photometric techniques. In samples processed by drying in the shade,by drying in the sun,and by steeping in 50% alcohol,its content is 311 mg/100 g,456 mg/100 g and 472 mg/100 g related to the dry weight. It reaches 1.73 mg/100 g in that processing by heating with deoxygenation,a noval method. The value of P. baphica is limited if traditional methods are used. The noval method can increase the content of the effective component and thus improve the quality drastically. It is possible to make the best use of P. baphica by the noval method.
