Growth Inhibitory, Bactericidal, and Morphostructural Effects of Dehydrocostus Lactone from Magnolia sieboldii Leaves on Antibiotic-Susceptible and -Resistant Strains of Helicobacter pylori
Figure 1
Structures of dehydrocostus lactone (1), costunolide, and parthenolide.
Dehydrocostus lactone is the guaianolide sesquiterpenoid identified in M. sieboldii leaves in this study, and costunolide and parthenolide are previously known germacranolide sesquiterpenoids.
