Phytochemical investigation of the roots of Pueraria lobata led to the isolation of two pairs of new isoflavone glucosides, 3'-hydroxyneopuerarin A/B (1-2) and 3'-methoxyneopuerarin A/B (3-4). A pair of known compounds (5-6), which possess a very similar structure, were obtained together. Their structures were elucidated on the basis of spectroscopic data interpretation. Compounds 3-6 dose-dependently blocked the production of TNF-α and IL-6 in LPS-stimulated RAW264.7 cells, which indicated the potential anti-inflammatory effect of these compounds.
