摘要
采用高效液相色谱法(HPLC)研究了不同环境胁迫下银杏构件种群中木解皮素和芦丁2种药用成分的动态变化。研究结果表明:干旱胁迫对木解皮素含量的提高有一定的促进作用,干旱胁迫反过来抑制了芦丁含量的增加;遮荫处理对提高银杏幼树叶片中药用成分含量有显著的促进作用;不同养分条件下银杏幼树叶片药用成分含量在1年中出现2次高峰;施肥对提高银杏药用成分含量作用明显,其中施尿素对提高叶片木解皮素含量有显著作用,施复合肥对提高叶片芦丁含量有显著作用。
High performance liquid chromatography (HPLC) was used to study the variation dynamics of the modular populations of Ginkgo biloba under different conditions of environmental stress. Drought stress promoted the growth of quercetin content and inhibited the growth of rutin content in the leaves. Shading treatment significantly increased flavone content in the leaves of young G. biloba. Under different nutrition conditions, two peaks were revealed of the medicinal components in the leaves in a year. Urea application significantly increased quercetin content while compound fertilizer significantly increased rutin content in the leaves of young plants.
