title: Two new triterpenoids from Picria fel-terrae.
abstract: Two new triterpenoids, picfeltarraegenin VII (1) and picfeltarraenin X (2), have been isolated from Picria fel-terrae Lour., along with three known ones, picfeltarraegenin VI (3), picfeltarraenins VI (4) and VII (5). Their structures have been elucidated by means of spectroscopic methods.
