川芎贮藏条件的研究

Study of Rhizoma Chuanxiong Storage Conditions

研究了不同包装材料和不同贮藏时间对川芎有效成分的影响,对采于两个GAP基地的川芎,在3年贮藏期内每半年照中国药典方法分别测定水分、挥发油、阿魏酸的含量,酸性染料比色法测定总生物碱含量。结果不同包装材料中以真空包装、麻袋、编织袋对川芎有效成分含量的损失影响最小。随贮藏时间延长,水分和挥发油含量均呈下降趋势,贮藏3年后,挥发油含量已经降至贮藏前的1/4～1/3。阿魏酸含量随贮藏时间延长有逐渐增加的趋势。总生物碱含量变化无规律,增减均有。结论建议川芎的包装材料可选用麻袋或编织袋,如装量小时,有条件可选用真空包装。结合贮藏期内有效成分的变化和川芎在贮藏中极易出现霉变、虫蛀现象,认为川芎不宜久贮。

Objective:To study the different packing and storage life effect on the content of effective element in Rhizoma Chuanxiong,so as to guide the packing、moist、volatile oil and ferulic acid in Rhizoma Chuanxiong from two GAP base by the related determination method in supplyment of China Pharmocopeia(2000).And the content of total alkaloids was determined by acid dye colorimentry.Results:The loss of effective element in Rhizoma Chuanxiong was the least when in vaccum packing、sack and weave packet.During the storage the content of moist and volatile oil decreased;the content of ferulic acid increased;the content variety of total alkaloids had no regulation.Conclusion:We should choose the sack and weave packet as the packing of Rhizoma Chuanxiong.If the quantity is small we should use vaccum packing.Conbined the changes of Rhizoma Chuanxiong effective element and the phenomenon of mildew and worm eaten during storage,we should not store it for long time.
