Abstract

In one aspect, the invention relates to isolated compounds useful as antifungal agents, for example, compounds having a structure represented by a formula: wherein R1 is hydrogen or hydroxyl; wherein R2 is hydrogen, a-xylose or β -xylose; and wherein R3 and R4 are each hydrogen or together oxygen, or a pharmaceutically acceptable salt therof; methods of isolating and puifying same; pharmaceutical compositions comprising same; agricultural compositions comprising same; and methods of treating and/or preventing fungal infections using same. In one aspect, R2 is not hydrogen or β-xylose when R1 is hydroxyl and R3 and R4 are together oxygen This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
