Abstract

Four new lanostanoid glycosides, 3beta, 7alpha-dihydroxy-24-methylene-lanost-8-en-21-oic acid 7-O-beta-D-glucopyranoside (1), 3beta,7alpha-dihydroxy-lanost-8, 24-dien-21-oic acid 7-O-beta-D-glucopyranoside (2), 7alpha-hydroxy-3-keto-lanost-8,24-dien-21-oic acid 7-O-beta-D-glucopyranoside (3), and 7alpha-hydroxy-3-keto-24-methylene-lanost-8-en-21-oic acid 7-O-beta-D-glucopyranoside (4) were isolated from the fruit bodies of Laetiporus versisporus. Compounds 1-4 were named laetiposides A-D, respectively. Their structures were established by extensive NMR experiments and chemical methods.
