Abstract: Some of the plant families known as excellent sources of essential oils; Umbelliferae (Apiaceae) is one of them. The objective of this study is to give an overview about content and constituents of oils from two umbelliferous crops, Coriandrum sativum L. and Foeniculum vulgare Mill, cultivated in Sudan. The essential oils from the samples were obtained by hydro-distillation and analyzed by GC-MS for identification of their chemical composition. The essential oil content of C. sativum fruits was 0.8% (v/w). About 97% of the present investigated coriander oil was monoterpenes, 87% of which were oxygenated. No sesquiterpenes were detected in the oil. The major constituents identified were linalool (64.61%) α-pinene (5.94%), (+)-2-bornanone (4.73%), α-terpinolene (6.79%), α-pinene (5.94%), and geranyl acetate (2.46%). Composition of the essential oil from coriander cultivated in Sudan resembled the composition of previously investigated essential oils from coriander world-wise in term of linalool domination. The essential oil content of F. vulgate fruits was 0.8% (v/w). Nineteen compounds were detected in the oil. Monoterpenes comprises the main constituents (98.06%), among which (80.67%) were oxygenated, whereas sesquiterpenes represent only about (0.66%) of the oil. Estragole (68.96%), D-limonene (15.41%) and anethole (8.51%) were the main identified constituents. According to the present research findings, F. vulgare cultivated in Sudan could be classified as estragole chemotype.
