Tocopherol quinone content of green algae and higher plants revised by a new high-sensitive fluorescence detection method using HPLC--effects of high light stress and senescence
A rapid, sensitive fluorescence method was applied here for detection of oxidized tocopherol quinones in total plant tissue extracts using HPLC, employing a post-column reduction of these compounds by a Zn column. Using this method, we were able to detect both alpha- and gamma-tocopherol quinones in...
