Composition and Quality of the Essential Oil of Coriander (Coriandrum sativum L.) from Argentina

Abstract The essential oils obtained from fruits of coriander growing in six different zones of Argentina were analyzed by GC, IR and olfactive evaluation. The composition of five commercial oils produced in two areas of Buenos Aires Province were compared with three Russian oils imported by the Argentinian fragrance and flavor industry. Twenty components were identified which accounted for 96.6-99–7% of the total oils composition. The main constituents were linalool (68.9-83–7%), γ-terpinene (2,2-5.1%), camphor (3.2-4.8%), α-pinene (1.0–6.5%), geraniol (1.4–3.2%) and geranyl acetate (0.8–3.8%). The contents of cis- and trans-linalool oxide (0.1–0.4%) were low.

The Essential Oil of Rosmarinus officinalis Growing in Argentina

ABSTRACT Rosemary oil was produced from plants grown in two different zones of Argentina (Sumalao and Castelar). The highest yield of fresh plant material and oil was found in Sumalao. The physico-chemical properties, chemical composition and odor quality of the Argentinian oils were very similar to commercial oil, in particular Portuguese oils. Twenty compounds were identified in the oils, of which the major ones were α-pinene (7.9–10.9%), myrcene (17.9–20.4%), 1,8-cineole (14.5–15.3%) camphor (9.0–9.3%) and β-caryophyllene (14.5–15.3%). Some differences were observed in chemical composition of two oils produced by different methods of distillation.

Composition of the Essential Oil of Pichana [Baccharis spartioides (Hook, et Arn.) Remy (Compositae)] from Different Populations of the Patagonia, Argentina

Abstract The essential oils of the aerial parts of Baccharis spartioides (Hook, et Arn.) Remy (Compositae) from three different Patagonian populations were obtained by hydrodistillation and analyzed by capillary GC and GC/M S. Fifty-four components, representing approximately 84.6–97.4% of the oil samples, were identified. The samples consisted mainly of hydrocarbons and oxygenated monoterpenes. The major constituents were limonene (28.7–56.7%), 6R-7R-bisabolone (3.2–9.1%), sabinene (0.1–11.0%) and citronellal (2.4–5.2%).
