Potential antiplatelet aggregation metabolites from the discarded sorghum ( L.) root.

Sorghum ( L.) is the fifth largest crop in the world and has potential health benefits, but vast quantities of sorghum roots are discarded after harvest. Based on the previous antiplatelet aggregation for this species, two new -substituted 3-indole alkaloids sorghumine A () and sorghumine B (), together with 14 known compounds (), were found from the water extract of sorghum roots.
