   Subscribe/Renew Journal


The oils obtained by water and steam distillation of pure needles, pure twigs, and twigs with needles of Pinus roxburghii have been studied. The oils were examined for specific gravity, optical rotation, refractive index, acid and ester values and esters calculated as bornyl acetate. The oil obtained from pure needles has the highest ester value and appears to be better in quality.
