Abstract
Two new triterpenes designated querspicatin A and querspicatin B have been isolated from the bark of Quercus spicata. They have been shown to be 3β-(3′,4′-dihydroxycinnamoyloxy)-9α-hydroxy-7-oxo-lup-20 (30)-ene and 3β,9α-dihydroxy-7-oxo-lup-20(30)-ene on the basis of their 1H NMR, 13C NMR and mass spectral data and chemical evidence. © 1989.
