Essential oil of Haplophyllum linifolium (L.) G.!Don fil. (Rutaceae)

The essential oils from the fruits and the aerial parts of Haplophyllum linifolium harvested in 1994 and 1997 were isolated by hydrodistillation, fractionated by dry column chromatography, and analyzed by GC and GUMS. The GC of the fruits exhibited 68 peaks from which 50 substances were structurally identified by MS and RI-values, which correspond to 98.8% and 98.2% of the oils, respectively. The main components of these oils were beta-phellandrene (25.5% and 35.5%) and beta-pinene (23.7% and 21.2%), but the more interesting characteristic is the presence of 4.6% and 2.9% bornyl formate, respectively, a compound rarely found in essential oils. The oil of the aerial parts of the plant exhibited a very similar oil composition differing only in the percentual proportions. beta-Phellandrene and beta-pinene were the dominating constituents of the herb oils representing 42.6% (30.4%) and 19.8% (22.4%), respectively. Bornyl formate amounted to 2.5% in 1994 and 4.0% in 1997.
