Abstract
White wax of m.p. 78-79° was obtained in 0.5% yield from the leaves of Biota orientalis. The constants of the wax were: acid value, 17.8; saponification value, 225.7; ester value, 207.9. Saponification of the wax yielded 81% of acid component and 7% of non-saponifiable matter. The acid component was composed chiefly of juniperic acid with the presence of a small amount of sabinic acid, which were present as estolides. Pentatriacontane and a hexadecane-1, 16-diol of m.p. 87-88° were obtained from the non-saponifiable matter.
