Anti-plasmodial and antioxidant activities of constituents of the seed shells of Symphonia globulifera Linn f.

abstract：:Allelopathy is the chemical mediated communication among plants. While on one hand there is growing interest in the field, on the other hand it is still debated as doubts exist at different levels. A number of compounds have been reported for their ability to influence plant growth, but the existence of this phenomeno...
