摘要
A new diarylheptanoid, 3,5-dimethoxyl-17-hydroxyl-4,19-diketo-11-ene-[7,0]metacyclophane, named as nanaone, was isolated from the bark of Myrica nana along with six known compounds. Their structures were elucidated by various spectroscopic methods including 2D-NMR techniques or comparison with authentic samples.
