| 摘 要： | 烘干、磨碎、过40目筛的牡丹叶样品，用水浸提法、醋酸铵浸提法及硫酸消化法制备待测液，火焰光度法测定牡丹叶钾的百分含量分别为0．978，9．0825，0．9788，显著性检验结果表明三者相关不显著，说明在测定牡丹叶含量时，可以用水浸提法制备待测液。

| Abstract: | Extracting was prepared by disilled water,distilled ammnium acetate and digested sulphuric acid respectively.Postassium percentage of dried and grinded peony leaf through 0.45?mm sieve by flame spectrometry was 0.978?9,0.982?5 and 0.978?8.It indicated that the difference of the three extractings was not obvious and so distilled water could be used to prepare extracting when measuring potassium content of peony leaves by flame spectrometry. |
