Figure Lengend Snippet: Chemical structures of compounds isolated from the endophytic fungus Alternaria alternata . Ergosterol (1), β -Sitosterol (2), Ergosterol peroxide (3), Fonsecinone A (4), Asperpyrone C (5), and Asperpyrone B (6), showing observed key HMBC correlations of compounds 4, 5 and 6

Article Snippet: 1D ( 1 H and 13 C) NMR and 2D (HMQC and HMBC) NMR spectra were recorded on a JEOL Eclipses ECS-400 NMR spectrometer (JEOL in., Peabody, MA, USA) at 400 MHz for 1 H NMR and 100 MHz for 13 C NMR, using the residual solvent peak ( H = 7.26 and C = 77.1, CDCl 3 ) as a reference.
