Parlat.; F fruticosa, Endl.; F. pyramidalis, A. Cunn.; F. ericoides, Hort; F. austral is, Endl.; Cupressus austral is, Persoon; Juniperus ericoides, Noisette) is widely distributed in the Southern states of Australia and known as black, red, or mountain pine.
The oil from the leaves (yield 0,162 p.c. in April, 0,168 p.c. in March) had the following properties; d17o 0,88631) to 0,8949; aD - 4,5 to + 11,7°; nD19o 1,4747 to 1,4760; ester content (hot) 38,6 to 46,58 p.c, (cold) 27,08 to 39,4 p.c, computed as C10H17Ococh8. It was soluble in an equal vol. of 80 p.c. alcohol, but the solution became turbid upon the addition of more solvent. In the carefully fractionated oil geranylacetate and d-bornyl acetate were found as the principal constituents. In the saponification liquid acetic acid and possibly butyric acid were present. The geraniol was identified by its oxidation to citral (naphthocinchoninic acid). In addition, the oil contains d-a-pinene, dipentene, d- and /-limo-nene. This species likewise contains more /-limonene in late summer than in winter.
The oil from the branches and fruits (yield 0,164 p.c. in December) had the following properties: d23/15 0,8803; aD - 4,5°; nD19o 1,4752; S. V. 110,38 = 38,6 p. c. ester computed as C10H17Ococh8. In the several fractions the following sub-stances were found: d-borneol (as acetate?), geraniol, resp. geranylacetate, /-limonene, dipentene (m. p. of tetrabromide 118°), and acetic acid in the saponification liquid.
The oil from the fruits was distilled in December with a yield of 0,229 p.c It is practically identical with the oil from the leaves, d23/15o 0,8797; aD + 2,15°; nD23o. 1,4744; S. V. (hot) 95,35 = 33,37 p.c. of ester computed as C10H17Ococh3 (cold 31,18 p.c). The geraniol was identified by its oxidation to citral.
