  • Antibacterial and antifungal flavanones from Eysenhardtia texana
    Patent number: 6136849
    Abstract: An activity-guided fractionation of a methanol-dichloromethane extract obtained from the aerial parts of Eysenhardtia texana Kunth. (Fabaceae) led to the isolation of two new antibacterial and antifungal flavanones. Their structures were established as 4',5,7-trihydroxy-8-methyl-6-(3-methyl-[2-butenyl])-(2S)-flavanone and 4',5,7-trihydroxy-6-methyl-8-(3-methyl-[2-butenyl])-(2S)-flavanone on the basis of their UV, ID and 2D-NMR spectra. These compounds have potent antibacterial and antifungal activity as measured by bioassay.
