摘要：

The methanol extract of Saussurea medusa Maxim afforded two lignans: 2alpha-guaicyl-4-oxo-6alpha-catechyl-3,7-dioxabicyclo [3.3.0]octane and 1alpha-hydroxy-2alpha,4alpha-guaicyl-3,7-dioxabicyclo[3.3.0]octane; two chlorophyll derivatives: 13-epi-phaeophorbide-a and 13-epi-phaeophorbide-a methyl ester; one megastigmane derivative: 3-hydroxy-5alpha,6alpha-epoxy-7-megastigmen-9-one, along with 19 known compounds. Their structures were established on the basis of spectroscopic studies. (C) 2002 Elsevier Science Ltd. All rights reserved.
