title: The isolation and antimicrobial activities of three monocylic sesquiterpenes from Syringa pinnatifolia.
abstract: We report the isolation of a new sesquiterpene, named as syripinol (1), and two known compounds from the volatile oil of the stems of Syringa pinnatifolia, for the first time. The structures of the isolated compounds were elucidated on the basis of spectroscopic methods including UV, IR, ESI-MS, 1D and 2D NMR techniques. The antibacterial activities of the compounds were also evaluated against various bacteria which showed good results.
