Composition of nucleosides in water extracts of Grifola gargal

Abstract

We isolated and purified aromatic compounds from water extracts of <i>Grifola gargal</i> and elucidated their structures by instrumental analysis. The results revealed that adenosine was one of the aromatic compounds in the extracts. Moreover, nucleosides (cytidine, uridine, guanosine, and thymidine) in the water extracts from <i>Grifola gargal</i> were identified by high-performance liquid chromatography (HPLC). In addition, the nucleoside contents of water extracts of 17 mushroom species were also identified by HPLC, and their quantitative values were determined by principal component analysis. <i>Pleurotus ostreatus</i> had the highest adenosine content among the tested mushrooms and different mushrooms had different amounts of nucleosides.
