Chemical Composition of the Essential Oil of <i>Bupleurum Fontanesii</i> (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Historical Art Crafts

Abstract

Hydrodistillation of the flowers (BpFI) of and fruits (BpFr) of Bupleurumfontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-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.
