摘 要:目的:比较石菖蒲鲜、干药材及其根茎和叶中挥发油,α-细辛醚和β-细辛醚的含量,为该药材的加工和用药方式选样提供实验依据。方法:采用水蒸气蒸馏法提取石菖蒲挥发油,通过超声提取法提取α-细辛醚和β-细辛醚,利用HPLC测定石菖蒲鲜品和干品根茎、叶中α-细辛醚和β-细辛醚的含量,流动相水-甲醇(65∶35),检测波长257 nm。根据样品处理条件折算出α-细辛醚和β-细辛醚的质量分数并进行比较。结果:石菖蒲经烘干处理后挥发油含量降低,根茎中挥发油的含量较叶中的含量高。β-细辛醚在鲜药材和干药材根茎中的质量分数分别为2.81%和1.70%,在鲜药材和干药材叶中质量分数分别为0.90%和0.75%。α-细辛醚在鲜药材和干药材根茎中的质量分数分别为0.03%和0.02%,在鲜药材和干药材叶中的质量分数分别为0.05%和0.04%。结论:石菖蒲干、鲜药材中活性成分的差异较小,均适合药用;石菖蒲叶中的活性成分含量不可忽视,考虑到叶在全草中占较大的比重,建议石菖蒲可以全草入药。Objective: To compare contents of volatile oil,α-asarone and β-asarone in rhizomes and leaves of fresh and dry products of Acori Tatarinowii Rhizoma,in order to provide experimental basis for reasonable appilication of this herb. Method: Volatile oil in Acori Tatarinowii Rhizoma was extracted by steam distillation,α-asarone and β-asarone in rhizomes and leaves were extracted by ultrasonic extraction method.HPLC was employed to determine contents of α-asarone and β-asarone with mobile phase of water-methanol (65 : 35) and detection wavelength at 257 nm. Result: The content of volatile oil in fresh products was markedly higher than that in dry products,this index in rhizomes was higher than that in leaves.Contents of α-asarone and β-asarone in fresh products was higher than that in dry products,the content of α-asarone in leaves was higher than that in rhizomes,the content of β-asarone in rhizomes was higher than that in leaves. Conclusion: Difference of active ingredients between dry and fresh products is small,both of them can be used in medicine.Contents of active ingredients in leaves can not be ignored,allowing for a large proportion of leaves in the whole herb,leaves of Acori Tatarinowii Rhizoma could be used in medicine.
