Abstract:
:Two new compounds, myrubol (1) and 3-oxo-11α-hydroxyfriedelane (2), were isolated from the roots of Myrica rubra along with eight known compounds (3-10). Their structures were determined through (1)H-NMR and (13)C-NMR spectral data, including 2-D experiments (HMBC, HMQC, (1)H-(1)H COSY and NOESY) and high-resolution mass spectrometry.
