Two new pimarane diterpenoids from Strychnos vanprukii Craib.
Two new pimarane diterpenoids, 7beta,12beta-dihydroxypimara-8,15-dien-14-one (1) and 14-hydroxy-15,16-dinorpimara-8,11,13-trien-7-one (2), were isolated from the n-hexane extract of the stem of Strychnos vanprukii Craib and their structures were elucidated based on spectroscopic evidences.
