โฆ Synopsis
A method is described for the liquid scintillation counting of 14C in plant tissues. Samples are fixed, in the scintillation vial, in a solution of ethanol and acetic acid (3:1) and decolorized with commercial bleach before the addition of scintillation liquid. The method was compared to other techniques of tissue oxidation or digestion and found to be equally effective at least with thin tissue samples. The technique is simple, rapid, and inexpensive and does not result in loss of 14C.

Benzoyl peroxide in toluene was used to bleach chlorophylls in alcohol extracts from plants fed with r4C0, for improved direct measurement by liquid scintillation counting. The 0.5% benzoyl peroxide was better than the saturated solution due to less color quenching. Increased counts occurred with al
The counting rate of [ 1-r4C] trichloroacetic acid (TCA) was not stable in a standard toluene/Triton X-100 liquid scintillation solution because this compound becomes partially degraded to 14C0, and CHCl,. Both toluene and Triton were contributing factors in causing this degradation. The NCS solubil
