【摘要】 采用气相色谱-质谱联用技术分析了北苍术和茅苍术的挥发油成分,分别鉴定出47和50种化学成分,并测定了其相对含量。采用色谱指纹图谱八强峰法和分区法,根据色谱峰的保留时间把总离子流色谱图分为5个区,比较了北苍术和茅苍术的挥发油成分。结果表明,在总离子流色谱图Ⅳ和Ⅴ区中,从北苍术和茅苍术中均检出苍术的主要药效成分β-桉叶油醇、苍术酮和苍术素,且相对含量较高。这表明《中国药典》将北苍术、茅苍术统称为苍术具有一定的科学性。更多还原

【Abstract】 The volatile oil components from Atractylodes chinensis(DC.) Koidz.and Atractylodes lancea(Thunb.) DC.were analyzed by GC-MS.Forty-seven and fifty components were identified,respectively,and their relative contents were determined.The volatile oil components from Atractylodes chinensis(DC.) Koidz.and Atractylodes lancea(Thunb.) DC.were further compared with each other by using the Eight Strong Peaks and Dividing Sections of the chromatographic fingerprint methods.The total ionic current chromatograms were divided into five fingerprint sections on the basis of peak retention time.The results showed that the major active components of Rhizoma Atractylodis are β-eudesmol,atractylon and atractylodin and they were identified with higher relative content in the Ⅳ and Ⅴ sections of the total ionic current chromatograms,suggesting that it was acceptable to combine Atractylodes chinensis(DC.) Koidz.and Atractylodes lancea(Thunb.) DC together as Rhizoma Atractylodis in the Pharmacopoeia of the People′s Republic of China.更多还原
