[Study of chemical constituents in active parts of Mentha spicata III].
OBJECTIVE
To study the chemical constituents of Mentha spicata.


METHODS
The chemical constituents were isolated by silica gel column chromatography, and identified by physical and chemical characters and spectroscopic analysis.


RESULTS
Compounds I - V were obtained and their structures were elucidated as protocatechuic aldehyde (I), protocatechuic acid (II), chrysoeriol (III), 5, 6-dihydroxy-7, 8, 3', 4'-tetramethoxyflavone (IV), nodifloretin (V).


CONCLUSIONS
Compound I and II were first isolated from the genus Mentha. Compound Ill, IV and V were isolated from M. spicata for the first time.
