Abstract:
Two new diterpenes were isolated from Juniperus przewalskii, together with 17 known terpense. Their structures were elucidated by spectroscopic methods (IR, MS, 1H, 13C and 2DNMR). In addition, 3 alpha-hinokiol (3) and 3 alpha-hydroxymannol (9) exhibited effective antitumor activities to cervical carcinoma (HeLa) and human ovarian carcinoma (HO-8910) cell lines.
