Chisiamols A-F, Triterpenoids from Chisocheton siamensis

Six new apotirucallane‐type triterpenoids, chisiamols A–F (1–6), along with two known compounds, were isolated from the twigs of Chisocheton siamensis. The structures of compounds 1–6 were established on the basis of spectroscopic and chemical methods.
