Abstract

A new alkaloid, tournesibirin (1), was isolated from the dichloromethane extracts from Tournefortia sibirica L. The structure of 1 was determined by spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.

Keywords: Boraginaceae; Tournefortia sibirica L.; alkaloid; tournesibirin.
