摘    要:采用高效液相色谱-四极杆飞行时间质谱(HPLC-Q-TOF MS)技术对条叶榕根茎乙酸乙酯提取物中的多种活性化学组分进行了分析鉴定。采用正离子与负离子两种扫描方式,依据高分辨质谱提供的准分子离子峰和碎片离子的精确分子质量信息,确证了有关物质及其特征碎片离子的分子组成。再结合标准品对照与相关文献数据支持,最终鉴定出条叶榕根茎乙酸乙酯提取物中的34种化学成分,其中包括12种多酚、8种香豆素、9种黄酮、4种脂肪酸、1种蒽醌。结果表明,采用HPLC-Q-TOF MS技术可提高中药化学成分的分析效率,有利于新化合物的发现与鉴别。

关 键 词:高效液相色谱-四极杆飞行时间质谱(HPLC-Q-TOF  MS)  条叶榕  化学组分  碎片离子

Abstract:The major chemical compounds in the ethyl acetate extract from Ficus pandurata Hance aerial roots were analyzed using high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF MS). The ESI-MS analysis was operated at the mass range of m/z 100-800 under both the positive and the negative ionization modes, respectively. A total of 34 compounds, such as 12 phenolics, 8 coumarins, 9 flavonoids, 4 fatty acids, and 1 anthraquinone, which are characterized in the ethyl acetate extract, based on the accurate mass of molecular and product ions provided by Q-TOF MS, comparison with standard substances and references. It is an effective method to provide chemical information concerning the constituents in herbal medicines, which makes component analysis more convinced.
Keywords:high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF MS)  Ficus pandurata Hance  chemical compounds  fragment ions
