Abstract
Stillingia oil is a Chinese raw material containing biosynthetically intriguing estolides. Oil extracted from the kernels of the seeds of Sapium sebiferum Roxb. was investigated using various high-performance liquid chromatographic (HPLC) techniques such as reversed-phase HPLC of the oil itself, its triacylglycerol and estolide fractions, both with refractive index and with UV detection at two different wavelengths, and using normal-phase (silica) HPLC of the tocopherols. Qualitative fingerprints and semi-quantitative results on triacylglycerols and estolides and on tocopherols are given. In the tocopherol fraction, stillingia oil contains nearly pure (92%) γ-tocotrienol.
