Two new dammarane‐type triterpenes, ailexcelone and ailexcelol, together with ocotillone, malabaricol, epoxymalabaricol, lupeol, and sitosterol‐3‐ O ‐ β ‐ D ‐glucoside were isolated from the heartwood of Ailanthus excelsa. The structures of the new compounds were established on the basis of 1D‐ and 2D‐NMR data. Ocotillone, malabaricol and epoxymalabaricol were isolated for the first time from A. excelsa. All of the isolates were tested for their antifungal activity.
