摘要: 用交叉极化(CP)-魔角旋转(MAS)技术得到两种类型植物沙米(Agriophllum squarrosum L. Moq.)和刺沙蓬(Salsola ruthenica Iljin)种子的一系列核磁共振碳-13(13C NMR)波谱,发现两种植物种子内蛋白质、碳水化合物含量不同,两种植物种子细胞壁结构也有差别,沙米主要是木葡聚糖,刺沙蓬主要是半乳甘露聚糖。

Abstract: A Series of nuclear magnetic resonance (NMR) spectra of Agriophyllum sguarrosum L, Moq.and Salsola ruthenica Iljin in whole seeds were obtained by using cross polarization magic angle spinning(CP MAS)technique,Spectra of seeds obtained from two types of desert plant show that protein and Carbohydrate content in them are different.
Cell wall spectra in seeds of Agriophyllum squarrosum L. Moq were dominated largely by resonances from Xyloglucans,while in spectra of Salsola ruthenica Iljin seeds was derived mainly from galactomannan.
