In a previous paper, we reported the isolation and structural
elucidation of triterpenoidal glycosides, justicioside A–D,1
from the aerial portion. Further investigations of the same
plant afforded three new triterpenoidal glycosides, which
have an unprecedented skeleton for the aglycone moiety
(A-nor-B-homo-olean-12-ene skeleton type). Their structures
were elucidated on the basis of chemical and
spectroscopic evidence. The present paper deals with the
isolation and structural elucidation of these compounds.
