Nineteen monoterpenoid indole alkaloids including seven new ones, melodinines A-G (1-7), were isolated from Melodinus henryi. The structures of the new compounds were elucidated using spectroscopic methods, and the Structure of compound 4 was confirmed by single-crystal X-ray diffraction ana...
Asarum caudigerum (Aristolochiaceae) is a paleoherb species that is important for research in origin and evolution of angiosperm flowers due to its basal position in the angiosperm phylogeny. In this study, a subtracted floral cDNA library from floral buds of A. caudigerum was constructed and...
Three new metabolites, vibralactones D-F (1-3) were isolated from cultures of the basidiomycete Boreostereum vibrans. The relative configuration of I was established on the basis of X-ray diffraction analysis, while the absolute configurations of 1-3 were assigned using a modified Mosher's me...
Rhododendron (Ericaceae) is a large woody genus in which hybridization is thought to play an important role in evolution and speciation, particularly in the Sino-Himalaya region where many interfertile species often occur sympatrically. Rhododendron agastum, a putative hybrid species, occurs ...
A yellow and new dark red pigments were isolated from Lethariella sernanderi, L. cashmeriana, and L. sinensis as antioxidant components. The yellow pigment was identified as canarione (1), and the others were determined to be 1,2-quinone derivatives, rubrocashmeriquinone (2) and 7-chlororubro...
