Volatile Constituents of Leaf Oils from the Cupressacea Family: Part II. Austrocedrus chilensis, Fitzroya cupressoides and Pilgerodendron uviferum Species Growing in Argentina

Abstract

The oils from Austrocedrus chilensis, Fitzroya cupressoides and Pilgerodendron uviferum leaves collected in the Argentinian Patagonia were isolated steam distillation yielding 0.50%; 0.22% and 0.19% of essential oils, respectively. Leaf oils were analyzed by GC and GC/MS. The main constituents of each oil were: (i) Austrocedrus chilensis oil: α-pinene (535%), myrcene (14.9%) and δ-3-carene (11,9%); (id Fitzroya cupressoides oil: α-pinene (40.8%), spathulenol (5.6%), (Z)-nerolidol (5.5%), cc-cadinol (4.4%) and cis-calamenene (4.4%); and (iii) Pilgerodendron uviferum oil: α-pinene (38.0%), α-bisabolol (13-0%), epi-α-muurolol (12.0%), δ-cadinene (11.9%), limonene (8.0%), β-pinene (3.4%) and myrcene (3.2%).
