联合应用ESI MS和1H NMR分析含笑属植物种子磷脂
Application of ESI-MS combined with 1 H NMR in analyzing seed phospolipids of six species of Michelia
摘要
Abstract
To date,there was no example to authenticate seed phospholipids based on their fingerprinting.By means of electrospray ionization mass spectrometry(ESI MS)and proton nuclear magnetic resonance(1 H NMR)spectroscopy,phospholipids fraction extracted from seeds of six species from the genus Michelia were detected.It was firstly found that distinct difference in spectral fingerprinting region between m/z 895-910 in ESI MS and 5.30-5.40 mg/L in 1 H NMR among these six species.Thus,it suggested that the spectral differences shown by ESI MS and 1 H NMR among seeds of these six species could be applied to identify them.And in a wider sense,for analyzing seed phospholipids of other plant species,a combination of ESI MS AND NMR was an effective tool.关键词
