In the present study, as part of our ongoing study on extraction and isolation the fruiting bodies of Daldinia concentria, we have succeeded in purification by a combination of conventional chromatographic techniques to result in five known compounds were identified as [11]-cytochalasa-6(12), 13-diene-1,21-dione-7,18,19-trihydroxy-16,18-dimethyl-10-phenyl- (7S*,13E,16S*,18S*, 19R*) (1), [11]-cytochalasa-6(12),diene-1,21-dione-7,18-dihydroxy16,18-dimethyl-10-phenyl-(7S*,13E,16S*,18R*) (2), ergosterol (3) and ergosterol peroxide (4), respectively, based on the comparison of their spectroscopic and spectrometric profiles (NMR, UV, IR, and MS). | Characterization of cytochalasins and steroids from the fruiting bodies of Daldinia concentrica in Viet Nam
