Cyclopeptide alkaloids from Scutia buxifolia Reiss and their antimicrobial activity

The chemical investigation of the methanolic root bark extract of Scutia buxifolia Reiss (Rhamnaceae) afforded a cyclopeptide alkaloid named Scutianine M (1) along with six known compounds. The antimicrobial activity of the isolated compounds was investigated towards Gram (+), Gram (−) bacteria, and yeasts.
