N2 - – Davidia involucrata (Nyssaceae) is a naturally rare plant found in southern China. We isolated two previously undescribed ellagitannins, davicratinic acid B (5) and C (6), in addition to four known compounds, davicratinic acid A (1), helioscopinin B (2), granatin A (3), and pedunculagin (4). Spectral analyses revealed that compounds 5 and 6 are modified dehydroellagitannins with isomeric structures.
