Abstract:
A new diterpenoid, 17-methyl-8, 13-labdadien-15, 16-olid-19-oic acid methyl ester (1), along with two known compounds 2 and 3, were isolated from the leaves of Platycladus orientalis (L.) Franco. The structures were confirmed based on the analysis of HR-MS, 1D-NMR, and 2D-NMR spectra and the configuration of 1 was confirmed by the single-crystal X-ray diffraction.
