In the quality department flavonoids are investigated since severeal years intensively. Research focusses on the identification of structures and the influence of irradiation and temperature. I am participating in many projects on structure identification.

The junior research group `Detection, biosynthesis and function of flavonoids´derives consequently from projects on flavonoids in the quality department. Working on e.g. the COST project UV4Growth, the Wega project and the LeguAN project, I already dealt intensively with questions on UV-radiation.

The projects of the junior research group should comprise plant physiological mechanisms of the effect of UV irradiation (UV-a and UV-B) and further irradiation qualities (low wave lengths up to 550nm) on flavonoids. In the framework of the junior research group structures of flavonoids in different plant species with varying flavonoid spectra according to flavonoid classes (Flavanoles (Flavan-3-oles or Catechine), Flavanones, Flavones, Flavonoles, Anthocyanidins und Isoflavonoides) will be identified.

Based on these chemical, structural different flavonoids, underlying plant physiological mechanisms of the effect of different irradiation qualities will be investigated by analytical (HPLC-MS, preparative HPLC, photospectrometrical methods) and molecular biological methods (RT-PCR, Microarrays). The dose and time of treatment with different irradiaton qualities will be measured to determine reproducible modifications of the flanovoid profiles of different plant species.

A second focus will address the stability of flavonoid profiles modified by different irradiations. Thermic processes will be simulated by models.  Changes in flavonoid profiles according to flavonoid classes will be detected and newly synthesized phenolic compounds identified.
