Chemistry of Essential Oils

46 THE CHEMISTEY OF ESSENTIAL OILS

was 206

• 33, equal to 72'2 per cent, of ester. In the separated alcohols
  both borneol and geraniol were identified. The high percentage of
  •ester in this fraction did not leave much room for the sesquiterpene or
  similar bodies.
  The fruits yielded 0363 per cent, of oil having a specific gravity
  0 877 at 16°, optical rotation - 17'9° and refractive index 1-4774 at 18°.
  The esters present were 588 per cent, calculated as bornyl acetate.

CALLITRIS VERRUCOSA.

The leaf and fruit oils have the characters tabulated below.

In the leaf oil both forms of limonene are present, dextro-limonene

predominating. About 3 per cent, of free alcohols (borneol ?) is present

in the oil.

CALLITRIS GLAUCA.
Dextro-pinene, dextro-limonene, and dipentene were identified in
the leaf oil of this species. Free borneol is present, and probably both
borneol and geraniol in the form of esters (acetate and butyrate ?).
