摘要：

The carbon-13 pulse Fourier transform nuclear magnetic resonance (NMR) technique for measurement of intact plant tissue has been used for the characterization and estimation of fatty acid composition in seeds of Leucas cephalotes, Stocksia brahuica, and Avena fatua. The carbon-13 NMR analysis of monoenoic and dienoic fatty acid concentrations was compared with destructive gas chromatographic analysis. The presence of laballenic esters in L. cephalotes and cyanolipids in S. brahuica can be detected by carbon-13 NMR spectroscopy. The isoprenoid hydroxynitrile moiety of the cyanolipid was shown to have the trans configuration. Carbohydrate digestion in the excised endosperm of the postgerminated A. fatua was observed by the carbon-13 NMR technique. © 1979, American Chemical Society. All rights reserved.
