Variation in chemical composition, insecticidal and antioxidant activities of essential oils from the leaves, stem barks, and roots of Blighia unijugata (Baker) and B. sapida (K. D. Koenig)
Blighia unijugata (Baker) and B. sapida (K.D. Koenig) (Sapindaceae) are forest trees widespread in Tropical Africa. They are used in folk medicine for the treatment of rheumatism, cardiovascular diseases, yellow fever, dysentery, and epilepsy. The essential oils of the air-dried leaves, stem bark, a...
