Abstract:In the present study we have developed a combine SPE and HPLC, that can be considered as a modification of a previous one (5) in two ways: first assuring a total recovery of pheophytin a and pyropheophytin a during SPE sample extraction, and secondly, improving selectivity of detection and sensitivity of quantification by using fluorescence detection.
