Determination of oil, starch, and protein content of viable intact seeds by carbon‐13 nuclear magnetic resonance

Dipolar‐decoupled natural abundance 13 C NMR spectra of some intact seeds have been obtained at 22.6 MHz. The spectra display reasonalby well resolved resonance lines for rigid materials, such as the starch and protein components of the seeds, in addition to well resolved lines for the mobile oil component, and, hence, should be useful in rapid nondestructive analyses of total composition.
