title: New α-pyrone and phthalide from the Xylariaceae fungus.
abstract: A new α-pyrone xylaripyrone A (1) and a new phthalide xylariphthalide A (2) were isolated from the Xylariaceae fungus (no. 63-19-7-3), along with four related known phthalides (3-6): 4-[(acetyloxy)methyl]-7-methoxy-6-methyl-1(3H)-isobenzofuranone (3), convolvulol (4), 7-methoxy-4,6-dimethyl-3H-isobenzofuran-1-one (5), and convolvulanic acid B (6). Their structures were determined on the basis of IR, MS, and NMR spectroscopic analyses.
