摘　要：

绿原酸是金银花(Lonicera japonica)入药的主要化学成分, 稳定和提高金银花中绿原酸含量的研究成为近年的一个研究热点。本研究通过对金银花分别施加Fe、Mn、B、Zn、Mo等微量元素, 研究微量元素水平对金银花中微量元素积累和绿原酸含量的影响, 结果表明: 土壤根施Fe、Mn、B、Zn和Mo对金银花中绿原酸的积累具有明显的促进作用, 其中施加Fe、B、Zn和Mo的效果极显著。土壤根施高浓度的B、Mo和中等浓度的Fe对金银花中微量元素的积累具有明显的促进作用。本研究为人工定向调控金银花中绿原酸含量, 开发人工栽培金银花专用微量元素肥料提供依据。

Abstract:

Chlorogenic acid is the main chemical component in honeysuckle (Lonicera japonica) for medicine. It has become a hotspot of research to stabilize and improve L. japonica chlorogenic acid in these years. Through giving trace elements such as Fe, Mn, B, Zn and Mo to L. japonica, the research compared the contents between trace elements and chlorogenic acid in L. japonica, and studied the effects of trace elements on the level of trace elements and the content of chlorogenic acid. The results show that it plays an obvious role in promoting chlorogenic acid of L. japonica to give the trace elements Fe, Mn, B, Zn and Mo to the root in the soil, especially the trace element Fe, B, Zn and Mo. It also plays an obvious role in promoting chlorogenic acid in L. japonica to give high concentrations of B and Mo and medium concentration of Fe to the root in the soil. The research provides important basis for controlling the content of L. japonica chlorogenic acid artificially and developing the trace element fertilizer which is dedicated to L. japonica of artificial cultivation.
