Abstract

From the bacterial gall of Myrica rubra, a new [7, 0] -metacyclophan (1) was isolated togetherwith three known compounds, myricanone (2), porson (3) and myricanol (4). The structure of the new compound was elucidated to be 5-deoxymyricanone (1) on the basis of spectroscopic evidence. The possible intermediacy of 1 in the biosynthesis of 2, 3 and 4 is discussed. DL-β-Phenyllactic acid was also isolated from the culture of Pseudomonas syringae pv. myricae pathogenic to the plant.
