- Abstract
Two new diterpenoids, pedunculatic acid A (= (4R,5α,7α)-7-ethoxy-9β,13β-dioxyabiet-8(14)-en-18-oic acid; 1) and pedunculatic acid 4;B (= (4S,5α,12β)-8β,14β-epoxy-12-hydroxy-11-oxototaran-19-oic acid; 2), together with three known sesquiterpenoids, were isolated from the Chinese medicinal herb Callicarpa pedunculata R. Brown. Their structures were elucidated by spectroscopic analyses, including 1D- and 2D-NMR, and by high-resolution mass spectrometry.
