The GC-MS identification of several abundant long-chain aliphatic n-alkyl caffeates, together with other phydroxycinnamic acid esters, in the dichloromethane extracts of the bark of Acacia dealbata and A. melanoxylon, is reported. In addition, the unambiguous differentiation between two delta7-steryl glucosides (namely, spinasteryl glucoside and dihydrospinasteryl glucosides) and the homologous delta5-steryl glucosides was achieved based on the EI-MS fragmentation features of their trimethylsilyl derivatives.
据报道，对银荆树和黑木相思树皮二氯甲烷提取物中的几种丰富的长链脂肪族正烷基咖啡酸盐以及其他对羟基肉桂酸酯进行了气相色谱-质谱联用（GC-MS）鉴定。此外，基于其三甲基硅烷基衍生物的电子轰击质谱（EI-MS）裂解特征，实现了两种δ7-甾醇葡萄糖苷（即菠菜甾醇葡萄糖苷和二氢菠菜甾醇葡萄糖苷）与同源δ5-甾醇葡萄糖苷之间的明确区分。
