Abstract:
Two new diterpenoids, gaultheric acid (1) and gaultheronoterpene (2), were isolated from the roots ofGaultheria yunnanensis. Their structures were elucidated as 12-hydroxy-13-acetyl-8,11, 13-podocarpatrien-18-oic acid (1) and 3beta, 12-dihydroxy-13-acetyl-4(18),8,11,13-podocarpatetraene (2) on the basis of spectral analysis.
