Abstract:
In continuation of our investigation, a new diterpene, rabdonervosin C (Ⅰ), was isolat-ed from the leaves and stems of Rabdosia nervosa (Hemsl.) C. Y. Wu et H. W. Li. Its structure wasidentified as lα, 15β, -dihydroxy-6β-ethoxy-6, 7-B-seco-ent-kaur-16-en-6, 20-epoxy-7, 20-δ-olide on thebasis of spectroscopic (MS, IR, 1HNMR, 13CNMR, DEPT and 2D-NMR) data and in comparison with theknown rabdonervosin A(Ⅲ) and B (Ⅱ).
