The present investigation aims to study the biological activity of concentration (40%) of Deverra tortuosa (DTSCP) and Haplophyllum tuberculatum (HTSCP) shoot crude powder as well as a mixture (w/w) of both donor species on Free amino acids, free proline, total antioxidant content and DPPH free radical scavenging assay of Triticum aestivum (crop species) and Phalaris minor (weed species) in pure and mixed cultures. In generalthe two plants exhibit a tendency to accumulate amino acids and free proline. The increase in free amino acids was higher in T .aestivumgrown in mixed culture compared to seedlings grown in pure culture. Treatment with both DTSCP and HTSCP caused an increase in free amino acid content in P. minor seedlings grown in mixed culture compared to seedlings grown in pure culture. Control T. aestivum seedlings grown in mixed culture had higher total antioxidant content compared to seedlings grown in pure culture. There was a significant increase in antioxidant in T. aestivum seedlings treated with 40% DTSCP. This showed that seedlings grown in mixed culture scavenge more free radicals compared to those grown in pure culture.
