Glyceride Composition of Sea Buckthorn Oil from Altai Krai

The compositions of sea buckthorn oil (SBO) glycerides in concentrates from various manufacturers in Altai Krai were studied using high-temperature gas chromatography. The effects of the isolation method and raw material composition on the ratio of SBO triglycerides were studied. It was shown that the analysis provided direct differentiation of mono-, di-, and triglycerides and had demonstrable advantages over methods of fatty-acid analysis employing preliminary sample preparation. It was established that the ratio of individual types of SBO glycerides could be a characteristic of the oil production method and the composition of the used raw material.
