Resonance combinational dispersion (RCD) of light was used for direct estimation of carotin in blood plasma without a previous extraction step. Intensity of RCD carotin lines in blood plasma correlated with that of standard beta-carotin solution in CCl4. Estimation of carotin concentration by means of RCD was compared with extraction-photometric procedure. The most suitable concentrations were 1.10(-5) = 1.10(-7) g/ml; 10 ml of blood plasma was sufficient for accurate measurements.
