摘要
Six novel diterpenes, sandaracopimaradien-9alpha-ol-1-one, sandaracopimaradien-1alpha,9alpha-diol, 6beta-acetoxysandaracopimaradien-9alpha-ol-1-one, sandaracopimaradien-6beta,9alpha-diol-1-one, 6beta-acetoxysandaracopimaradien-1alpha,9alpha-diol and sandaracopimaradien-1alpha,6beta,9alpha-triol have been isolated from the rhizomes of Kaempferia sp. The structures were assigned on the basis of their spectroscopic data and by chemical conversions. The crystal structures of the second and fifth compounds were also determined and the absolute stereochemistry of all the compounds established by CD methods.
