[Chemical Constituents of Paulownia tomentosa Fruits].
OBJECTIVE
To investigate the chemical constituents from the fruits of Paulownia tomentosa.


METHODS
The compounds were isolated and purified by column chromatography and their structures were identified on the basis of physicochemical properties and spectral analyses.


RESULTS
Seven compounds were isolated and their structures were identified as ursolic acid (1), sesamin(2),2α,3α, 19a-trihydroxyurs-12-en-28-oic acid(3), luteolin(4), tricin-7-O-β-D-glucoside(5),3',4',5,7-tetrahydroxy-6-[7-hydroxy-3,7-dimethyl-2(E)-octenyl] flavanone(6) and stigmasterol(7).


CONCLUSIONS
Compounds 3, 5 and 7 are isolated from Paulownia genus for the first time. Compound 2 is isolated from Paulownia tomentosa for the first time.
