Abstract Two unusual 18,19‐secoursane glycosides, bodiniosides A ( 1 ) and B ( 2 ), and two known triterpenoids, hypadienic acid ( 3 ) and 2,3,19‐trihydroxyurs‐12‐en‐28‐oic acid ( 4 ), were isolated from the whole plants of Elsholtzia bodinieri. The structures of 1 and 2 were determined by intensive interpretation of spectral data. This is the first report of E‐secoursane glycosides. In addition, the biogenetic relationships among these four triterpenoids are discussed.
