To study the chemical constituents of the leave of Paulownia tomentosa.
The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
The compounds were identified as apigenin(I), uteolin(II), homoeriodictyol(III), 3alpha-hydroxyurs-12-en-28-oic acid (IV),3beta,19alpha-dihydroxyurs-12en-28-oic acid (pomolic acid)(V),2alpha,3a-dihydroxyurs-12-en-28-oic acid(VI),ursolic acid (VII),2alpha,3beta-dihydroxyolean-12-en-28-oic acid (maslinic acid) (VIII), daucosterol(IX),beta-sitosterol(X).
The compound I-X are obtained from the leave of Paulownia tomentosa (Thunb.) Steud for the first time.
