Preliminary Study of Chemical Constituents of Paulownia taiwaniana

บทคัดย่อ

Paulownia taiwaniana (Scrophulariaceae), a fast-growing species from Taiwan, was firstly introduced to Thailand. Its wood has been widely used as well as its bark, root, flower, fruits and leaves for medical purposes in China. This preliminary study shows that the wood has large extractable material from which two crystalline compounds have been isolated at the present Based on the melting point and spectroscopic comparison, they are identified to be d-sesamin and paulownin respectively.
