Abstract

Two new compounds, 15-methoxypinusolidic acid (1) and isonerylgeraniol-18-oic acid (2) together with four knowns taiwaniaflavone (3), nerylgeraniol-18-oic acid (4), 3-(3,4-dihydroxyphenyl)-1-propanol (5), and amentoflavone (6) are isolated from the leaves of Calocedrus microlepic var. formosana. Compounds 1 and 2 were elucidated as labdane diterpene and linear diterpene, respectively, through spectral studies.
