These compounds possess strong antibacterial activity and have a distinctive structure composed of a benzene, a quinone, and a stereospecific pyran
ring (Lu et al.
One is the ring-opening reaction of the depolymerized xylan unit through the cleavage of the hemiacetal bond (between oxygen and C-1 on the pyran
ring), followed by dehydration between the hydroxyl groups on the C2 and C5 positions.
