Popis: Two organic acid glycosides (1, 2) and 16 sterols were isolated from the royal jelly of honeybees (Apis mellifera). The former two were monoglucosides of 10-hydroxy-2E-decenoic and 10-hydroxydecanoic acids. They are the first examples of glycosides isolated from royal jelly. The latter 16 were sterols mainly composed of 28 or 29 carbons. Among them, four compounds were new isofucosterol derivatives, and their structures were characterized as (24Z)-stigmasta-5,24(28)-dien-3beta-ol-7-one (3), (24Z)-stigmasta-5,24(28)-diene-3beta,7beta-diol (4), (24Z)-stigmasta-5,24(28)-diene-3beta,7alpha-diol (5), and (24Z)-stigmast-24(28)-ene-3beta,5alpha,6beta-triol (6) on the basis of various NMR spectroscopic data.
