Resveratrol, a new phenolic compound, from Veratrum grandiflorum
The English summary, established by Prof. Ebizuka: He isolated a phenolic compound, by crystallization alone!!, from an ether soluble and non-basic fraction of EtOH extracts of Veratrum grandiflorum Loes. fil. collected in Hokkaido Island. Molecular formula was obtained by elemental analysis of itself, its triacetate and trimethylether. CrO3 oxidation of trimethylether in AcOH at room temperature afforded 3,5-dimethoxybenzaldehyde, while in boiling AcOH produced p-anisic acid. These degradation products were identified by direct comparison with authentic specimens. Some additional information including color reactions and comparison of UV spectrum with some stilbene derivatives led him to conclude its structure.
