Volatile Constituents ofRidolfia segetum(L.) Moris Gathered in Southern Spain, Andalucia Province

The volatile oils of the different aerial parts of Ridolfia segetum (L.) Moris (Apiaceae) gathered in Andalucia (Spain) were analyzed by capillary GC and GC/MS. The oil from the stems was characterized by a high content of α-phellandrene (39.4–62.0%), p-cymene (10.4–22.7%), (Z)-β-ocimene (10.2–11.7%) and terpinolene (7.0–15.6%), whereas the leaf oil was shown to contain α-phellandrene (61.8%-69.5%), (Z)-β-ocimene (10.7–12.0%) and terpinolene (6.0–10.7%) as major constituents. The flower oil was also dominated by α-phellandrene (44.5–54.7%), (Z)-β-ocimene (8.5–10.6%) and terpinolene (20.1–27.6%), while the main components of the fruit oils were found to be β-pinene (1.5–11.9%), α-phellandrene (5.2–56.9%), p-cymene (4.2–25.2%), β-phellandrene (0.9–15.6%), terpinolene (4.3–12.5%) and dillapiole (0.1–45.7%).
