Occurrence

A glucosidic sulphur-containing alkaloid, xylostosidine occurs in the water-soluble fraction of the extract of Lonicera xylosteum. It forms colourless needles when crystallized from MeOH and is laevorotatory with a specific rotation of [α]D -289.37° (c 0.56, MeOH). The ultraviolet spectrum in MeOH consists of a single absorption maximum at 238 nm. Acetylation furnishes the tetraacetate which is laevorotatory with a specific rotation of [α]D20D -85.35° (c 0.35, CHCl3).
