“…The genus Xylaria Hill ex Schrank comprises more than 300 species, some of which have received special attention due to their potential as sources of novel secondary metabolites. A recent review showed that more than 180 compounds, including sesquiterpenoids, diterpenoids, diterpene glycosides, triterpene glycosides, steroids, N-containing compounds, pyrone derivatives, and polyketides, have been isolated from this genus [20,21]. Specifically, from X. feejeensis, integric acid, xylaropyrone, and the nonenolide xyolide have been isolated.…”
