采用石蜡切片和组织解离法对白术的根作生药学研究 ,采用挥发油测定法对白术根和根茎的有效成分挥发油的含量作比较研究 ,采用薄层层析法对白术根和根茎的挥发油成分进行比较研究。结果 :白术根的产量为根茎产量的 2 1 .96% ,其有效成分挥发油的含量为 0 .847ml 1 0 0g,相当于根茎挥发油含量的62 .74% ,白术根挥发油的薄层层析图谱和根茎的完全一致
The root of Atractylodes macrocephala Koidz was studied by paraffin section and tissue dissociation method. Volatile oil assay was used to compare the volatile oil content of Atractylodes macrocephala root and rhizome, and the volatile oil components of Atractylodes macrocephala root and rhizome were determined by thin layer chromatography. Conduct comparative studies. Result: The yield of Atractylodes macrocephala root was 21.96% of rhizome yield, and the content of volatile oil in its active ingredient was 0.847ml 100g, which was equivalent to 62.74% of rhizome volatile oil content. The thin layer chromatography chromatogram of Atractylodes macrocephala was studied. Consistent with rhizome
