Summary

Primary Study on Chemical Constituents of Lasia spinosa L.

Lasia spinosa L. (Araceae) is used in the Vietnamese traditional and folk medicine for treating sore throat, cough, nephritis, rheumatism, liver diseases (hepatitis, ascitic cirrhosis), sequels of malaria and skin diseases. For the first time, three benzaldehyde derivatives (p-hydroxy benzaldehyde, p-hydroxy benzoic acid, 3-hydroxy-4-methoxy benzoic acid), 2-(4-methoxyphenyl)ethanol and adenine were isolated from Lasia spinosa L. The structures of these compounds were elucidated by spectroscopic methods.
