Chemical Composition and Allelopathic Potential of the Essential Oil from Datura Stramonium L.
Abstract:
In this paper, we analyzed the chemical composition of the essential oil from Datura Stramonium L. and determined their phytotoxic activity on five cultivated crops. The main components of essential oil were sterols and their derivatives, and the major constituents were 5.alpha.-Ergosta-7,22-dien-3.beta.-ol (16.53%), 3-Hydroxycholestan-5-yl, acetate (14.97%), and 26,26-Dimethyl-5,24(28)-ergostadien-3.beta.-ol (10.39%). The essential oil and its aqueous saturated solution from D. Stramonium significantly inhibited the germination and growth of lettuce, radish, common bean, maize, and cucumber. The results indicated that D. Stramonium may release allelochemicals, both water-soluble and volatile compositions, into environment to inhibit other plant species.
