New apotirucallane-type triterpenoids from Chisocheton paniculatus

Abstract

Two new apotirucallane triterpenoids, namely chisiamols G (1) and H (2), featuring a 21,23-lactone, together with five known triterpenoids, were isolated from the twigs of Chisocheton paniculatus. The structures of the new compounds were elucidated on the basis of spectroscopic and chemical methods. Graphical abstract: [Figure not available: see fulltext.].
