Abstract
Changes in lipid classes and water-soluble components in maturing seed of Chinese tallow tree were examined. Rapid oil production occurred at three stages of seed maturity. Stillingia oil syntheses in seed kern proceeded more rapidly than stillingia tallow on the kern at early stage. Analytical data for components in immature seed suggest that the pathway of seed oil synthesis is the same as Kennedy's pathway. However, the appear-ance of monoglycerides indicates the existence of a side pathway. From specific positional distribution of fatty acids in mono-, di-, and triglyceride from immature seed, synthetic process of glyceride structure was discussed.
