Three tetranortriterpenoids, walsuranins A–C (1–3), as well as three known tetranortriterpenoids, anthothecol, 11β-hydroxydihydrocedrelone, and 11β-acetoxydihydrocedrelone, were isolated from the twigs and leaves of Walsura yunnanensis C. Y. Wu. Their structures were established on the basis of spectroscopic methods. Walsuranins B–C (2, 3) from this plant featured the typical rearranged A-ring structure of this compound class.
