摘要：
The refraction indices of sea-buckthorn (Hippophaë rhamnoides L. – Elaeagnaceae) oil for two wavelengths are measured in this study by using laser and Abbe refractometer at 632.8 and 589.3 nm, respectively. The transmission spectra in the visible and near infrared regions are obtained by using a Carry 5E spectrophotometer. Cauchy's and Sellmeier's coefficients were calculated and the dispersion curve n(λ) is obtained. Using only refractometric data, the oscillating (E0) and dispersion (Ed) energies are calculated. Refractometric analysis of sea-buckthorn (Hippophaë rhamnoides L. – Elaeagnaceae) oil mixed with refined and non-refined sunflower oil is made as well.
