[A study on chemical constituents in seeds of Crataegus pinnatifida Bge. var. major N. E. Br].
OBJECTIVE
To study the chemical constituents in the seed of Crataegus pinnatifida var. major.


METHODS
Four compounds were isolated and identified by column chromatography and 1H, 13C-NMR data.


RESULTS
The compounds obtained were identified as protocatechuic acid, gallic acid, catechol and p-hydroxybenzoic acid.


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