摘要
为了确定锁阳最佳采收期,对不同时期锁阳的主要营养成分、酚类成分、无机元素进行了测定.结果显示:4月份采集的锁阳肉质茎主要营养成分、酚类成分、无机元素的含量最高,1月份次之,3月份最低;还原糖与总黄酮在各自成分中的含量最高,且还原糖的含量随着月份的增加逐渐减小,而各月份粗脂肪含量差异较小;另外锁阳肉质茎含有较高的无机元素和微量元素,其中K、Na、Mg、Cu、Mn、Fe的含量4月份最高,其他月份的含量相对较低.由此可知,锁阳药材的最佳采收期为4月底.
In order to make sure the best harvest period of Cynomoriurn songaricurn, the main nutritional components, phenolics and inorganic elements of Cynomorium songaricum in different growth periods were studied. The results showed that the main nutritional components, phenolics and inorganic elements in succulent stems of Cynornorium songaricurn collected in April were the highest, then followed by January, and those of Cynomorium songaricum collected in March were the lowest. Reducing sugar and total fla- vonoids contents were the highest in their respective components, which decreased with the increasing of month, the crude fat contents had no significant difference among different months. In addition, there were higher contain inorganic and trace elements, especially K, Na, Mg, Cu, Mn and Fe were all the highest in A- pril. The results indicated that the end of April was the best harvest period for Cynornoriurn songaricum.
