[Studies on the chemical constituents from Xinjiang Punica granatum].

OBJECTIVE

To study the chemical constituents from Punica granatum.

METHODS

The chemical constituents were isolated by column chromatography on silica gel and MCI-gel CHP 20P, Sephadex LH-20. Their structures were elucidated on the basis of spectral analysis and physical constants.

RESULTS

Ten compounds were isolated and elucidated as: gallic acid (1), methyl gallate (2), ellagic acid (3), (+) catechin (4), isoquerecitrin (5), D-mannitol (6), ursolic acid (7), Oleanolic acid (8), beta-Sitosterol (9) and Daucosterol (10).

CONCLUSION

Compounds 1-10 are isolated from this plant for the first time.
