The crude wax, obtained in 1.5% yield from the leaves of Hinoki (Chamaecyparis obtusa), was saponified and treated as shown in Chart 1, and, besides the components already known, lauric acid, triacontanoic acid, dodecane-1, 12-dioic acid, nonacosane, pentatriacontane, and nonacosan-10-one were isolated (Table I). This is the first example of isolation of dodecane-1, 12-dioic acid as a plant component. The content of each component calculated from alumina chromatographic results is shown in Table II.
