Secoiridoid glucosides from Swertia mileensis.
Five new acyl secoiridoid glucosides along with three known secoiridoid glucosides, swertiamarin, 2'-O-acetylswertiamarin, and amarogentin, were isolated from the aerial parts of Swertia mileensis. The structures of these compounds were determined to be 2'-O-acetyl-4'-O-trans-feruloylswertiamarin, 2'-O-acetyl-4'-O-cis-feruloylswertiamarin, 2'-O-acetyl-4'-O-trans-p-coumaroylswertiamarin, 2'-O-acetyl-4'-O-cis-p-coumaroylswertiamarin, and 4'-O-trans-p-coumaroylswertiamarin from spectroscopic evidence.
