Peltigera aphthosa

A further hopane constituent of the lichen Peltigera aphthosa is phlebic acid B (125). " Woodwardic acid, from Woodwardia orientalis, is 3jff-hydroxy-21y5H-hop-22(29)-ene-23-carboxylic acid (126). Mollugogenol E (127), from Mollugo hirta, has been correlated with niollugogenol A. [Pg.176]

Phlebic acid A, which co-occurs in the lichen Peltigera aphthosa with 15a-acetoxy-22-hydroxyhopane (dustanin monoacetate) is 28-acetoxy-22-hydroxy-hopan-23-oic acid (216). Mollugogenol B and C, new saponins from Mollugo... [Pg.195]

Starting in the 1500s, the doctrine of signatures was an ubiquitous concept in European medicine. It was thought that plants looked like the organ or ailment that they cured and various lichens were adopted into the European pharmacopoeia as a result. The main medicinal lichens in early modem era Europe were Cetraria islandica, Cladonia pyxidata, Peltigera canina, Peltigera aphthosa, Usnea spp., Lobaria pulmonaria, Xanthoria parietina, and Evernia prunastri. For more details, refer to these lichens in the tables below. The widespread use of these lichens had been mostly abandoned by 1800, with the exception of Cetraria islandica, which has persisted as a medicinal lichen in parts of Europe until today. [Pg.34]

Finally aphthosin (278), an orcinol tetradepside was obtained through condensing evernic acid (279) and methyl lecanorate (280) (Scheme 36) (57). The properties of this synthetic material were identical with those of the natural product isolated by Bachelor and King 10), although a reinvestigation of the constituents of Peltigera aphthosa failed to verify the natural occurrence of this tetradepside 234). [Pg.158]
