Three New Diarylheptanoids from Myrica nana

Abstract

Three new cyclic diarylheptanoids myricananins F–H (1–3, resp.), along with five known ones, 4–8, were isolated from the roots of Myrica nana. Compound 3 has been obtained by Nagai et al. by reduction of porson with NaBH₄. In this work, compound 3 was isolated from natural origin for the first time. The structures of 1–8 were elucidated using spectroscopic methods.
