The small, ground fruits of Pittosporum pentandrum (Blanco), Merrill, which grows principally in the lowlands of the Philippines, yielded upon distillation1) an oil (210 cc. from 16 kg.) which boiled between 153 and 160°. Washed with solution of caustic alkali and distilled over sodium, it had the following properties: b. p. 155 to 160° (principally 157 to 160°); d30/4o0,8274; aD30o(+?)40,4o; nD30o 1,4620. Hence it may be assumed that the oil consisted principally of the dihydroterpene found in the petroleum nuts as described above. Heptane, however, was not present.
