摘 要：
采用电喷雾萃取电离质谱法(EESI-MS),对荒草、马尾松、木荷等3种根际土壤样品溶液进行了直接快速质谱分析,区分了3种土壤中有机物质组成的差异.该方法能够承受土壤样品中复杂基质的影响,根据所得到的一级谱图可以发现3种土壤样品中化学组成的差异;采用串联质谱(IT-MS)法,则鉴定出马尾松根际土壤样品溶液中含有去氢枞酸,而木荷根际土壤样品溶液中含有丁香醛和松脂素.

摘 要：
A method based on extractive electrospray ionization mass spectrometry(EESI-MS) was developed to obtain the mass spectra of three types of soil samples with minimal sample pre-treatment.EESI could tolerate the complex matrices of soil sample solutions and readily generate mass spectra without sample cleaning.The mass spectra clearly demonstrated the differences of organics among three types of soil samples.Dehydroabietic acid and the combination of syringaldehyde and pinoresinol were detected in extracts of Pinus massoniana and Schima superba Gardn et.Champ.respectively by extractive electrosprary ionization tandem mass spectrometry(EESI-MS/MS).
