Two new triterpenoid glycosides from Centipeda minima

摘要

Two new trierpenoid glycosides have been isolated from the whole plant of Centipeda minima. They are characterized as 1#beta#, 2#alpha#,3#beta#,19#alpha#-tetrahydroxy urs-12-ene-28-oate-3-O-#beta#-D-xylopyranoside 1 and 1#beta#, 2#beta#, 3#beta#, 19#alpha#- tetrahydroxy urs-12-ene-28-ate-3-O-#beta#-D-xylopyranoside 2 and their structures elucidated by spectral and chemical studies.
