增液汤不同配伍对梓醇含量的影响

Catalpol Content in Zengye Decoctions Prepared According to Different Prescriptions

目的 比较增泣汤的几种配伍中梓醇含量的差异。方法 方法以反向高效液相色谱法（RP-HPLC）测定增液汤不同配伍情况下的各处方中梓醇的含量。结果 地黄单味药梓醇煎出量为1．13％，其他配伍煎出量为1．21％～1．51%。结论 地黄与其他药味合煎可促进梓醇的煎出，其中与麦冬合煎梓醇的煎出量最高。

OBJECTIVE To compare the differences in catalpol contents of Zengye decoctions （a traditional Chinese herbal preparation）prepared according to varied prescription. METHODS Reverse phase-high performance liquid chromatography（RP-HPLC） was employed to determine the content of catalpol in different Zengye decoctions. RESULTS catalpol contents in the decoction of exclusive radix rehmanniae was 1.13 % ,and in Zengye decoctions composed of 2 or 3 ingredients, the contents varied from 1.210% to 1.51%. CONCLUSION The presence of the constituents in Zengye decoction such as radix ophiopogonis, radix scrophulariae may increase the release of catalpol content from within radix rehmanniae into the decoction.
