Distribution of morphinan and benzo[c]phenanthridine alkaloid gene transcript accumulation in Papaver somninferum.

abstract：:In addition to Z-coniferyl and Z-sinapyl alcohols, bark extracts of Fagus grandifolia also contain significant amounts of the glucosides, Z-coniferin, Z-isoconiferin (previously called faguside) and Z-syringin. The corresponding E-isomers of these glucosides do not accumulate to a detectable level. The accumulation ...
