Chemical Constituents of the Pericarp of Platycladus orientalis

In previous papers, we have reported two new compounds, 15‐hydroxypinusolidic acid and platydiol, from the pericarp of Platycladus orientalis. In addition to the above compounds, the isolation and identification of twenty‐one compounds from the same source are described. Their structures were determined on the basis of spectral evidence as well as direct comparison with authentic samples. These compounds included four fatty alcohols and acids, three monolignols, one sesquiterpene, nine diterpenes, two steroids, one flavone, and one sugar. Among these, docosyl 3‐hydroxyferulate is a new compound. And docosyl trans ‐ and cis ‐ferulates were isolated in pure form.
