Abstract
The wax from the leaves of Chamaecyparis obtusa was separated into acid and neutral estolides and the acid estolide was fractionated into various portions by chromatography and in petroleum solvents of various melting points. From the determination of acid and ester values of each portion, the molecular weight of the estolide and the mean molecular weight of the acid constituting the estolide were calculated. It was clarified from these values that the estolide is composed of three to five molecules of juniperic and sabinic acids.
