From the measurement of constants and the components obtained by the saponification of the leaf wax from 38 kinds of Confiferales examined, it was found that the Coniferal wax could be divided into two groups, A and B. A Group consists of Juniperus, Chamaecyparis, Thujopsis, Thuja, Biota, Cunninghamia, Cryptomeria, Taiwania, Pinus, Cedrus, Abies, Tsuga, Picea, and Torreya, while the B Group consists of Sciadopitys, Larix, Pseudolarix, Pseudotsuga, Cephalotaxus, Podocarpus, and Taxus. The wax from the A Group possesses a large ester number and the chief component is estolides of juniperic and sabinic acids. The wax from the B Group does not contain these estolides as a chief component or is totally devoid of them. There is no instance that two groups of plants are present in one genus. 1, 12-Dodecanediol, 1, 16-hexadecanediol, 10-nonacosanol, and melissyl alcohol were detected from the non-saponifiable matter.
