[Studies on chemical constitutes of Phellinus igniarius].

To study the chemical constituents of Phellinus igniarius. Compounds were isolated by nomal phasc sillica gel and Al2O3 chromatography and reverse phase HPLC. Their structures were elucidated by spectroscopic methods including IR, MS and NMR. Five flavonoids and two coumarins were isolated from Phellinus igniarius and their structures were identified as naringenin, sakuranetin, aromadendrin, folerogenin, eriodictyol, coumarin and scopoletin. All these compounds were obtained from this genus for the first time.
