Characterization of Phenolic Compounds from Parmelia reticulata Tayl

Secondary metabolite composition of the bioactive extract fractions of Parmelia reticulata was analyzed using high-performance liquid chromatography coupled with mass spectrometry followed by isolation of metabolites by chromatographic techniques using a polarity gradient. Compounds obtained were characterized using spectroscopy techniques. Structure elucidation of obtained metabolites is discussed (Pr XIIb, Pr XIIIb and Pr XIVb), and 2D NMR (HMBC and HSBC) spectral data of Pr XIV are reported for the very first time.
