Enantiomeric pairs of meroterpenoids from Rhododendron fastigiatum

Chinese Journal of Natural Medicines, 2019
Five pairs of optically pure meroterpenoid enantiomers (1a/1b-5a/5b) and two known compounds (6 and 7) were isolated from Rhododendron fastigiatum. Compounds 1a/1b-5a/5b were resolved from naturally scalemic mixtures by chiral HPLC. Their structures were elucidated by spectroscopic methods, X-ray crystallographic experiments, and ECD analyses ...

Renoprotective meroterpenoids from the fungus Ganoderma cochlear

Fitoterapia, 2019
Nine multifarious new meroterpenoids, cochlearols E-M (1-9), along with seven known meroterpenoids 10-16, were isolated from the fruiting bodies of Ganoderma cochlear. Racemic 1, 6-8, 10 and 13 were separated by chiral HPLC. The structures were elucidated based on detailed spectroscopic analyses (HRESIMS, 1D/2D-NMR) and calculated electronic circular ...
