[Studies on the chemical constituents of Litsea lancifolia].
OBJECTIVE
To study the chemical constituents of Litsea lancifolia.


METHODS
AU compounds were isolated from the diethyl ether extract of the title herb by sillica gel column chromatogrphy, and their structures were identified by physical and chemical evidences and spectral methods.


RESULTS
Seven compounds were isolated and identified as (-)-aristortetralone (1), dehydrodiisoeugenol ( 2), dihydrodehydrodiconifery alcohol ( 3) , 5,7-dimethoxy-3', 4'-methylenedioxyflavan-3-ol (4), p-hydroxy-benzoic acid (5), vanillin(6), p-sitosterol (7), respectively.


CONCLUSIONS
All compounds are isolated from this plant for the first time.
