Further chemical investigation of the stem bark of Aglaia cordata has led to the isolation and identification
of three new lignans, namely, aglacins I−K (1−3), all of which contain two contiguous trimethoxylated
phenyl systems. Among them, aglacins I and J (1 and 2) are new members of the aryltetralin cyclic lactol
class, while aglacin K (3) is a new example of tetrahydrofuran lignan. The structures of these compounds
were established on the basis of spectroscopic data interpretation.
