Analytical data for the active extract of Humicola fuscoatra (UCSC strain no. 108111A). (A) Evaporative light scattering chromatogram collected during automated peak library fractionation. Annotations indicate the distribution of compounds 1–7 (see Experimental Section for elution conditions). (B) ESITOF(+) m/z data collected during peak library fractionation. Expansion of [M + Na]⁺ ion for radicicol (1), at t_R = 27 min (see panel A). (C) 600 MHz ¹H NMR spectrum in acetone-d₆. Numbered annotations are those of the major component, radicicol (1). “L” denotes lipids. The expanded region shows the aromatic singlet of the most abundant minor congener, compound 4.
