Pine-needle oil is produced primarily in Eastern (Hungary)
and Southeastern (Bulgaria) Europe by steam distillation of the needles of
the Norwegian or Scotch pine, Pinus sylvestris L. var. sylvestris or Pinus
nigra Arnold ssp. nigra. It is a colorless or yellowish liquid with an aromatic,
turpentine-like odor. In China, pine-needle oil is also obtained from Pinus massoniana Lamb.
d25 0.857–0.885; n20D 1.4730–1.4785; α20D ?4 ° to +10 °; solubility: 1 vol in 6 vol of 90% ethanol, sometimes slightly opalescent; ester content (calculated as bornyl acetate): 1.5–5%.
물리적 성질
The oil is a clear, colorless or yellow-green, volatile liquid. It is soluble in most fixed oils,
mineral oil (with opalescence). It is slightly soluble in propylene glycol and practically insoluble in glycerin. The physical–chemical
constants vary widely, depending on the plant source.
출처
Found in the leaves (needles) of Pinus sylvestris L. (Fam. Pinaceae).
제조 방법
By steam-distillation of the leaves (needles) of P. sylvestris L.
Essential oil composition
