<jats:title>Abstract</jats:title><jats:p>Isolation of alkaloids from ripe fruits of Ligustrum vulgare L. using 5% H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub> and NH<jats:sub>3</jats:sub>, results in up to 12 spots on TLC giving positive tests with <jats:italic>Dragendorff</jats:italic> reagent. However, these compounds have been proved to be artifacts, generated by ammonia from secoiridoid glucosides. Four monomeric alkaloids have already been described. Meanwhile two dimeric pyridine alkaloids LA 4 (1) and LA 5 (2) have been isolated. Their structures were established on the basis of spectroscopic data.
