Definition:Members of the class of tetrahydrochromenochromene that consists of a cis-fused tetrahydrochromeno[3,4-b]chromene skeleton and its substituted derivatives. The term was originally restricted to natural products, but is now also used to describe semi-synthetic and fully synthetic compounds.
