Organic acids as a botanical geographical marker of Egyptian, Chinese and German bee pollens

Abstract EN

Organic acids in bee pollen samples represented from different geographically regions of Egypt, China and Germany countries were estimated using high performance liquid chromatography (HPLC) as a chemical marker of these regions.

The number of organic acids present in samples of tested bee pollens were eight in Egyptian, six in Chinese and five in German organic acids bee pollens.

There was only one organic acid (Citric acid) commonly found in the all tested types of bee pollens.

Oxalic acid it can be used to differentiate between German bee pollen and the other under study.

Also, malonic acid was absent in Chinese pollen while it was found in other bee pollens tested.

So, organic acids can be used to distinguish among the main different types of pollens (Egyptian, Chinese and German).
