Isolation and structural elucidation of allelochemicals from wheat

The wide variety of methods employed in isolation of benzoxazinoid allelochemicals has been optimised. The phytochemical constituents of wheat varieties in study afforded 250 fractions belonging to DCM and EtOAc extracts. We have studied them providing 40 major compounds, belonging to the flavonoids, simple phenolic and steroid families and one very abundant monoterpene.

Needs addressed
The methodology has led us to get access to the target compounds (DIMBOA, DIBOA and their glycosides). A complete phytochemical study of selected wheat varieties has been achieved. These compounds have to be obtained in amounts and purities enough to complete their bioactivity profiles and to get analytical standards to complete their determination in plant, soil and bioassay experiments.
