The volatile oils hydrodistilled from the aerial parts and roots of O. carduchorum C.C Towns. (Fabaceae) have been chemically characterized for first time. A total 43 constituents with an abundance >0.03% were identified quantified in two by GC/MS GC/FID analyses. They comprise 38 components (98.58%) oil isolated (OCA) 34 (93.33%) (OCR). Six constituents, α-pinene (23.11 ± 0.1%), β-elemene (17.33 1,8-cineole (12.15 0.2%), furfural (7.91 terpineol-4-ol (6.32 limonene (4.13 accounted about...
