Three novel diepoxy tetrahydrochromones from agarwood artificially produced by intentional wounding

Three novel diepoxy tetrahydrochromones, oxidoagarochromones A ( 1 ), B ( 2 ), and C ( 3 ), were isolated from intentionally wounded agarwood and they are considered to be produced at the early stage of agarwood formation. Three novel diepoxy tetrahydrochromones, oxidoagarochromones A ( 1 ), B ( 2 )...

Description
Summary:Three novel diepoxy tetrahydrochromones, oxidoagarochromones A ( 1 ), B ( 2 ), and C ( 3 ), were isolated from intentionally wounded agarwood and they are considered to be produced at the early stage of agarwood formation. Three novel diepoxy tetrahydrochromones, oxidoagarochromones A ( 1 ), B ( 2 ), and C ( 3 ), were isolated from agarwood artificially produced by intentional wounding of Aquilaria crassna. Inductive production of these compounds was also confirmed at the early stage of wounding in A. sinensis and A. crassna. These diepoxy tetrahydrochromones would play an important role in understanding the biosynthesis of chromone derivatives in agarwood.
