液相色谱（LC）与负电喷雾电离（ESI）串联质谱（MS/MS）联用，用于快速、灵敏地鉴定柳叶阿高瑞香中的黄酮类化合物。发现来自生态地理环境和形态特征差异显著的种群的柳叶阿高瑞香个体的叶片黄酮含量在定性上存在差异，在定量上差异很大。通过对紫外光谱、质谱和串联质谱图的解析来鉴定化合物。鉴定出了14种黄酮类化合物，所有这些化合物此前在阿高瑞香属中均未见报道。发现两种黄酮醇 - O - 葡萄糖醛酸苷可区分这两个种群。（c）2007爱思唯尔有限公司。保留所有权利。
Liquid chromatography (LC) coupled to negative electrospray ionisation (ESI) tandem mass spectrometry (MS/MS) was used for the rapid and sensitive identification of flavonoid compounds in Agauria salicifolia. The leaf flavonoid content in individual of A. salicifolia originating from population with contrasted ecogeographical situation and morphological characteristics was found to be variable qualitatively and highly variable quantitatively. Identification of the compounds was carried out by interpretation of UV, MS and MS/MS spectra. Fourteen flavonoids were identified, all of which had not previously been reported in Agauria spp. Two flavonol-O-glucuronides were found to differentiate the two populations.
