[Pharmacognostical studies on imported and cultivated Citrullus colocynthis].

OBJECTIVE

In order to use Citrullus colocynthis safety and correctly,The pharmacognosy of imported and cultivated Citrullus colocynthis was systematically studied.

METHODS

The morphological characters, microscopical identification, and thin layer Chromatograpy (TLC) were studied.

RESULTS

The characters of import and cultivated Citrullus colocynthis were approximately identical, but there were still some differences between them, such as: the fruit size of cultivated Citrullus colocynthis was largish, granulose were more, trachea were thicker, collenchyma were longer, the colour of spots in TCL were more clear.

CONCLUSION

There were seldon difference between import and cultivated Citrullus colocynthis, and cultivated Citrullus colocynthis could take the place of import's if planted on a large scale.
