Abstract Using a new method of "susceptibility matching" by CCl4, we found that the proton nuclear magnetic resonance (NMR) spectrum of intact mustard (Sinapis alba L.) seeds consists of NMR lines, originating from oil bodies (microdroplets) surrounded by a solid structure. The intact seed resonances in CCI4 were identified as­ CH3 at 0.9 ppm, -(CH2)n- at 1.3 ppm, and -CH=CH- at 5.3 ppm, respectively. The protons of the glyceride structure were detectable at 4.2 ppm. An additional heterogenous line was also measured at about 2.2 ppm
