ABSTRACT

OBJECTIVE: To study the phenolic acids from the aerial part of Clerodendranthus spicatus. METHODS: The phenolic acids were isolated from the aqueous extract of C. spicatus by various chromatographic methods, and their structures were elucida-ted on the basis of their physicochemistry properties and spectral data. RESULTS: A new phenolic acid possess a unique bicycle [2.2.2] octane skeleton was obtained from the aqueous extract of the aerial part of C. spicatus. CONCLUSION: Compound 1 is a new phenolic acid and named cleroden E.
