Abstract:
Two new cycloartane-type triterpenoids 25-hydroxyl-9,19-cycloart-22-ene-3-one (1) and (23Z)-9,19-cycloart-23-ene-3alpha,25-diol (2) along with 9,19-cycloart-25-ene-3beta, 24xi-diol (3) and cycloeucalenol (4) have been isolated from the leaves and stems of Fritillaria hupehensis Hsiao et K.C. Hsia. Their structures were elucidated on the basis of spectroscopic analysis.
