目的:确定防风抽薹对药材质量和产量的影响.方法:比较抽薹和未抽薹防风各发育阶段根直径、折干率和单位体积重量,并采用高效液相色谱法测定四种色原酮成分的含量.结果:抽薹防风药材中4种色原酮含量并未表现出明显的降低,但抽薹防风各发育阶段根的直径不增长,折干率和单位体积的干重显著低于未抽薹防风.结论:防风抽薹对质量没有产生明显影响,但能够导致产量降低.

We studied the variations of both quality and yield of bolting Saposhnikovia divaricata roots in different prepara- tion phases.Roots diameter,fresh/dry weight ratio,and unit weight were compared between the bolted plants and un- bolted plants,and four different chromes concentrations in the roots were determined using HPLC.We found that the bolted plants did not have an increased diameter of roots in the development phase,though with a noticeably reduced fresh/dry weight ratio and unit weight.The chromes c...
