A number of depsidones in the meta series are aldehydes fumarprotoce-traric acid, stictic acid, norstictic acid (72), constictic acid, (73),pannarin, physodalic acid, protocetraric acid, psoromic acid, salazinic acid, and virensic acid. They react with / -phenylenediamine to give yellow to red condensation products (P+ substances). [Pg.510]

Neither Usno nor other lichen medicines have, however, gained a permanent position in the medical praxis the fight for a place in the sun among antibiotics is too hard. Since the last decade the medicinal research of lichens has turned to new directions the untiring Japanese group Nakazava, Komatsu, Hamada, Fujikawa, Hirai, Shibata et al. has studied the antitumor activity of lichens intensively since 1962. This activity obviously depends on the polysaccharide component in lichens, as found in Umbilicaria, Lasallia, Cetraria, Cladonia, Parmelia, and Usnea, and from psoromic acid. [Pg.558]
