Formiside and seco-formiside: lignin glycosides from leaves of Clerodendrum formicarum Gurke (Lamiaceae) from Cameroon

摘要

The ethanol soluble part of the leaves of Clerodendrum formicarum, a Lameacious plant of Cameroon, afforded two new lignin glycosides named formiside and seco-formiside. Structures of both the isolated constituents have been elucidated with the aid of 1D and 2D NMR spectroscopic techniques.
