[Studies on the chemical constituents from the leave of Paulownia tomentosa].
Zhong Yao Cai. 2011 Feb; 34(2):232-4.ZY

Abstract

OBJECTIVE

To study the chemical constituents of the leave of Paulownia tomentosa.

METHODS

The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.

RESULTS

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).

CONCLUSION

The compound I-X are obtained from the leave of Paulownia tomentosa (Thunb.) Steud for the first time.
