摘  要:
利用液相色谱-二极管阵列-电喷雾质谱联用(HPLC-PDA-ESI/MS)对芥蓝中脱硫芥子油苷进行鉴定,通过分析各种脱硫芥子油苷在正、负离子两种模式下的质谱特点和PDA图谱特点,由正、离子两种模式下的脱硫芥子油苷离子碎片信息可以推断出芥蓝中含有11种脱硫芥子油苷,其中7种为脂肪族芥子油苷、4种为吲哚族芥子油苷。进一步对PDA图谱分析发现,因结构差异,脂肪族脱硫芥子油苷在220~230nm波长范围内只有一个大的吸收峰,而吲哚族脱硫芥子油苷在220~230nm波长范围内有两个吸收峰。

摘  要:
Desulpho-glucosinolates in Chinese kale were identified by high performance liquid chromatography-photodiode array-electrospray ionization(HPLC-PDA-ESI/MS) through analyzing properties of MS and PDA under both positive and negative ion modes.Eleven glucosinolates including 7 aliphatic glucosinolates and 4 indolyl glucosinolates in Chinese kale were identified based on ion fragmentations under both negative and positive ESI modes.Further analysis of PDA spectra revealed only one absorption peak for aliphatic desulpho-glucosinolates and two absorption peaks for indolyl desulpho-glucosinolates due to the structure diversity.
