目的探索梓醇在怀地黄叶生长过程中的积累分布规律,为开发梓醇资源提供新思路.方法采用高效液相色谱法测定新鲜药材中的梓醇含量.流动相:乙腈-水(0.6:99.4),检测波长:210nm,回归方程Y=377.26X-1.054 3.测定不同发育阶段的怀地黄叶的水分含量,换算成干燥品中梓醇的含量.结果怀地黄叶与块根中均含有梓醇.地黄叶中的梓醇含量先迅速上升.在8、9月份的生长旺盛期达到最大值.然后逐渐降低直到地黄叶枯萎、凋谢.地黄块根中的梓醇随块根的增大而不断增多,一直持续到采收期收获.结论怀地黄中的梓醇积累变化是植物生理调节的结果.怀地黄叶中含有大量梓醇,应根据其积累规律进行深入研究.以利于地黄的综合利用.

Objective To explore the distribution and accumulation regularity of catalpol in leaves during the growth of Rehmannia glutinosa var. huechingensis. Methods HPLC method was used to determine the catalpol content in fresh medicinal materials with acetonitrile-water (0.6:99.4) as the mobile phase and 210 nm as detection wavelength. Regression equation was Y = 377.26X - 1. 054 3. The water contents of the leaves at different developmental stages were also determined, so that the catalpol content could be achieved on dry matter basis.Results Both leaves and root tubers contained catalpol. The content of catalpol in leaves rised up to peak rapidly in August or September and then degraded gradually until leaves wither and fall. The content of catalpol in root tubers increased with the growth of root tubers and reached peak until harvest. Conclusions The variation of catalpol is caused by the physiological regulation of plants. The leaves contain a considerable amount of catalpol. Further study is needed to benefit the comprehensive utilization of Rehmannia glutinosa Libosch.
