Two new cycloartane-type triterpenoids and one new flavanone from the leaves of Dasymaschalon dasymaschalum and their biological activity

Two new cycloartane-type triterpenoids, one new flavanone, two new natural products of benzoate derivative, and ten known compounds were isolated from the leaves of Dasymaschalon dasymaschalum. The structures of these compounds were established on the basis of spectroscopic data and comparison with reported values. Antimycobacterial, antiplasmodial and cytotoxic activities of the isolates were evaluated.
