Chemical Composition of the Essential Oil of Bupleurum fontanesii (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Historical Art Crafts

摘要

Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Camel gave two oils that were analyzed by GC and GC-MS. The main components were alpha-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and alpha-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.
