桑黄化学成分研究

Studies On Chemical Constitutes of Phellinus igniarius

目的 :对药用真菌桑黄进行化学成分研究。方法 :利用正相硅胶柱层析 ,Al2 O3柱层析 ,SephadexLH 2 0柱层析 ,反相HPLC ,重结晶等分离手段和IR ,MS及 1D ,2DNMR等结构鉴定光谱方法。结果 :从桑黄中分离鉴定了 5个黄酮和两个香豆素类化合物 ,分别为柚皮素、樱花亭、二氢莰非素、7 甲氧基二氢莰非素、北美圣草素、香豆素及莨菪亭。结论

Objiedtive:To study the chemical constituents of Phellinus igniarius . Method: Compounds were isolated by nomal phasc sillica gel and Al 2O 3 chromatography and reverse phase HPLC. Their structures were elucidated by spectroscopic methods including IR, MS and NMR. Result: Five flavonoids and two coumarins were isolated from Phellinus igniarius and their structures were identified as naringenin, sakuranetin, aromadendrin, folerogenin, eriodictyol, coumarin and scopoletin. Conclusion: All these compounds were obtained from this genus for the first time.[
