New iridoid glycoside and triterpenoid glycoside from Premna fulva.

Liquid chromatography-photodiode array detector-mass spectrometry-based chemical investigation of the leaves and stems of Premna fulva yielded one new iridoid glycoside (1), one new triterpenoid glycoside (2) along with six known compounds isolated for the first time from the genus. Their structures were established on the basis of extensive spectroscopic data analyses and chemical methods.
