The present study was conducted with the aim to investigate the effects of nine distillation times (DT 5, 10, ,20, 40, 80, 120, 160, 180 and 240 min) and 11 distillation fractions (DF 0-5, 5-10, 10-15, 15-20, 20-25, 25-30, 30-35, 35-40, 40-60, 60-80 and 80-100 min) on essential oil content and composition of lavandin (Lavandula x intermedia var. Super A). Essential oil was obtained by hydro distillation method. Composition of essential oil was identified with GC/MS. Lavandin essential oil content increased with length of the DT and reached maximum at 180 min (2.00%) DT. Fifty per cent of the total essential oil was obtained at the initial DT (5 min). Linalool, linalyl acetate, borneol, 1,8 cineole and camphor were determined as the main components in lavandin essential oils. The concentration of bomeol and 1,8 cineole (2.00 and 4.8%, respectively), linalool (53.50%), camphor (2.00%) and linalyl acetate (41.50%) was high at the 0-5, 5-10, 15-20 and 30-35 min, respectively, and decreased with increasing DT. In these distillation fractions, the highest essential oil content of lavandin ranged from 1.05, 0.41, 0.21 and 0.067%, respectively. As a result, distillation time may be shortened to obtain high linalool and linalyl acetate content. Also, the essential oil which is produced in early minutes, having camphor at high contents is removed and the oil produced after 20th min having camphor at lower contents is used especially in perfumery.
