Abstract

A new chromone derivative, xylariacetal (1), and a known isocoumarin, mullein (2), were isolated from Xylaria sp. ECN-008, which was derived from the leaves of Ardisia crenata. The structure of the new compound was identified by various spectroscopic techniques including 1D- and 2D-NMR. Xylariacetal (1) exhibits a characteristic tricyclic structure with an acetal moiety.
