Isolation and Structure Elucidation of Novel Natural Products from Turkish Lichens
摘要：
Three natural products were isolated from three dierent Turkish lichens. Microbiological investiga- tions were also examined of these lichens. Compound 1 is known as 2-hydroxy-4-methoxy-3,6-dimethyl benzoic acid, and is isolated from Pseudevernia furfuracea for the rst time. Compounds 2 and 3 are de- tected as new compounds and called, 3-acetyl-4-amino-2-chloro-1-(4-hydroxy-2-methoxy- 6-methylphenyl carbonyloxy) benzene and 2-(4-methoxyphenyl)-2-(5-oxo-4-phenyl-2,5-dihydro-2-furaniliden) acetic acid; they were isolated from Evernia prunastri and Letharia vulpina, respectively. All these compounds had dierent skeletons. Their structures were established by chemical methods and spectroscopic techniques using IR, UV, 1D and 2D NMR and EI and (+) FAB-Mass methods.
