The four new sesquiterpenoids 1 – 4 , and the new 2‐(2‐phenylethyl)‐4 H ‐chromen‐4‐one (=2‐(2‐phenylethyl)‐4 H ‐1‐benzopyran‐4‐one) derivative 5 , together with the two known sesquiterpenoids 6 and 7 , the five known chromenones 8 – 12 , and 1‐hydroxy‐1,5‐diphenylpentan‐3‐one ( 13 ), were isolated from a 70% MeOH extract of Aquilaria malaccensis agarwood chips. Their structures were elucidated on the basis of comprehensive spectral analyses and comparison with literature data.
