Objective: To study the chemical constituents from fruiting bodies of Amanita caesarea.
Methods: Silica gel column chromatography was applied for the isolation and purification of the constituents. The structures were established by means of spectroscopic and chemical data.
Results: Eight compounds were obtained and identified as ergosterol( 1),ergosterol peroxide( 2),9,11-dehydroergosterol peroxide( 3),glycerol-1-monooleate( 4),ethyl oleate( 5),( 2S,3R,4E,8E)-1-( β-D-glucopyranosyl)-3-hydroxy-2-[( R)-2’-hydroxyoctadecanoyl]amino-9-methyl-4,8-octadecadiene( 6),tetradecy lamine( 7) and berberine( 8).
Conclusion: All the compounds are isolated from Amanita caesarea for the first time.
