          <dc:description>Investigation of the non-polar fraction of Boesenbergia pandurata of Myanmar led to the identification of six&#13; novel secondary metabolites, panduratins D—I (1—6), together with known diastereomers, panduratins B1 (7)&#13; and B2 (8). Their structures were determined based on extensive spectroscopic analysis. The in vitro preferential&#13; cytotoxicity of all isolates was examined against human pancreatic PANC-1 cancer cells under nutrient-deprived&#13; conditions. All exhibited a mild activity.</dc:description>
