Webone spot. Chlorophyll a has a methyl group (-CH 3) in a position where chlorophyll b has an aldehyde (-CHO); look on left side of structures below. This makes chlorophyll b slightly more polar than chlorophyll a. After we isolate the pigment mixture from the leaves in a hexane solution, we will use the difference in polarity to separate the various
WebJun 12, 2024 · Students use thin-layer chromatography to separate the various pigments that are present in two different leaf extracts. They identify each pigment and determine whether the two extracts have any pigments in common. The experiment is suitable for students aged 11–16 and takes 1–2 hours to complete. WebAnalysis of chlorophyll degradation and phyllobilin accumulation by high-performance liquid chromatography (HPLC) is a valuable tool to investigate senescence processes in plants. In this chapter, methods for the extraction, separation, and quantification of chlorophyll and its degradation products are described.
WebApr 27, 2024 · One well-known technique to separate the chlorophyll is using distillation under vacuum. During wiped film distillation, the extract is fed into a heated column with a rotating wiper blade that evenly distributes the extract onto the surface of the walls.
