Abstract

Composition of ajowan (Trachyspermum ammi (L.) Syn. Carum copticum Hiern) seeds and physicochemical characteristics of essential oils from this spice were determined. GC-MS analysis of oil extracts showed the presence of 17 constituents, of which thymol (39.36%), gamma-terpinene (30.97%), p-cymene (19.47%), beta-pinene (5.45%) and alpha-pinene (1.48%) were the major constituents. Yield of oleoresin was 24.66%; oleoresin was comprised of 12.15% volatile oil and 87.85% non-volatile material. Oleoresin samples kept in cool conditions (8-10C) and at ambient temp. (25-30C) for 60 days did not show any significant changes in quality.
