Cymbalaria muralis subsp. pilosa contains a new iridoid, which we have named muralioside, besides the known antirrhinoside, linarioside, antirrhide, linaride, 8-epiloganic acid and macfadienoside. Muralioside was shown to be 7 beta-hydroxy-harpagide by spectroscopic means and probably arises from the opening of the epoxide ring of antirrhinoside. Following this biogenetic suggestion, the partial synthesis of muralioside from antirrhinoside was carried out by protic acid catalysis. Copyright (C) 1997 Elsevier Science Ltd.

Abstract
Cymbalaria muralis subsp. pilosa contains a new iridoid, which we have named muralioside, besides the known antirrhinoside, linarioside, antirrhide, linaride, 8-epiloganic acid and macfadienoside. Muralioside was shown to be 7 beta-hydroxy-harpagide by spectroscopic means and probably arises from the opening of the epoxide ring of antirrhinoside. Following this biogenetic suggestion, the partial synthesis of muralioside from antirrhinoside was carried out by protic acid catalysis.
