Liquid chromatography (LC) diode array detection (DAD) coupled to negative electrospray ionization (ESI) tandem mass spectrometry (MS/MS) was used for the rapid and sensitive identification of water-soluble phenolic compounds in fennel waste. The plant material was first extracted and then chromatographed on Sephadex LH-20 to afford seven fractions, each of them being subjected to LC-MS analysis. Identification of the compounds was carried out by interpretation of UV, MS, and MS/MS spectra. Forty-two phenolic substances were identified, 27 of which had not previously been reported in fennel, including hydroxycinnamic acid derivatives, flavonoid glycosides, and flavonoid aglycons.
液相色谱（LC）二极管阵列检测（DAD）与负电喷雾电离（ESI）串联质谱（MS/MS）联用，用于快速、灵敏地鉴定茴香废料中的水溶性酚类化合物。首先对植物材料进行提取，然后在葡聚糖LH-20上进行色谱分离，得到七个馏分，每个馏分都进行LC-MS分析。通过对紫外光谱、质谱和串联质谱的解析来鉴定化合物。共鉴定出42种酚类物质，其中27种此前未在茴香中报道过，包括羟基肉桂酸衍生物、黄酮苷和黄酮苷元。
