الملخص EN

A comparative chemical study of the seeds of two Cassia senna was performed to ascertain if distinct chemical substances could be identified to distinguish the two Cassias under investigation.

The initial problem raised by the finding that these two Cassia senna were morphologically practically identical has been resolved by the experimental results, which were found to be in agreement with the previous studies.

As can be seen from the conclusions, it is now possible to distinguish between these two plants.

It may be concluded that the two Cassias under investigaion are two species.
