Changes on oil yield and fatty acid profiles were studied during maturation of coriander (Coriandrum sativum L.) fruits cultivated in Menzel Temime and Oued Beja, Tunisia. Oil and petroselinic acid biosynthesis proceeded at a steady rate up to 16 DAF in Oued Beja and in 33 DAF in Menzel Temime. The first results show that a rapid oil accumulation started at newly formed fruits and continued until their full maturity. During fruit maturation, fatty acid profiles varied significantly among the growing regions and stages of maturity. Petroselinic acid had the highest amount at the 16th and the 33th DAF, in Oued Beja and Menzel Temime, respectively. In Oued Beja, at full maturity, the main fatty acids were petroselinic acid (80.90 ± 9.45%), followed by oleic (14.79 ± 2.25%), palmitic (3.50 ± 0.65%) and stearic (0.49 ± 0.09%) acids. Fatty acid profile of fruits cultivated in Menzel Temime showed that in fully ripe fruit, petroselinic acid is the main compound (80.86 ± 7.23%) followed by oleic (14.83 ± 2.05%), palmitic (3.27 ± 3.12%) and stearic (0.31 ± 0.05%) acids. In both growing region, fruit development resulted mainly in an increase of petroselinic acid and a decrease of palmitic acid. Saturated and polyunsaturated fatty acids decreased significantly and monounsaturated fatty acids increased during maturation of fruit. Oil composition at the first four stages of maturity has a healthy and nutritionally value and the last stages were with important economic and industrial applications. Coriander fruit is potentially an important source of petroselinic which have numerous industrial applications.
