Marasmane sesquiterpenes isolated from Russula foetens.
One lactone marasmane sesquiterpene named 8a,13-dihydroxy-marasm-5-oic acid gamma-lactone (1) and one unsaturated marasmane sesquiterpene named 13-hydroxy-marasm-7(8)-en-5-methoxy gamma-acetal (2) together with a known compound: 7alpha, 8alpha, 13-trihydroxy-marasm-5-oic acid gamma-lactone (3) were isolated from the fruiting bodies of Russula foetens. Their structures were established on the basis of spectral methods (MS, IR, ID and 2D NMR experiments).
