The yield, quality and composition of essential oils from sweet basil plants grown in Israel have been investigated. It has been found that at the same phenological stage the content of essential oil in the plant increases towards the autumn. The oil content increases as the plant develops and reaches its maximum in the full bloom stage. The presence of two chemotypes (A and B) of Ocimum basilicum L. plants was established. The variation in composition of the oil during the period of bloom was investigated for both chemotypes. Up to 25 % of the total of basil oil of type A and 50 % of type B oil were extracted from distillation water by the poroplast column technique. This secondary oil, of pleasant odour, contains mainly the most polar compounds, such as eugenol, linalool and cineol.
