Column Chromatography of Plant Pigments Paul Ibarbia‚ Gene Paolo Jasmin‚ Gianpaolo Jimenez and Lorenzo Labicane* Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column chromatography of plant pigments is the separation of plant pigments extracted from Capsicum frutescens (siling labuyo). No slurry is prepared of the eluent; eluent with the stationary phase is set and then carefully poured into the column. The eluent are the solvents which are responsible for the

Hormone Control of Leaf Abscission Lab Report February 24‚ 2011 By Patrick Mills Introduction- Hormones are a chemical are transported within an organism and are highly specific chemical signals between cells. The hormones we used were lanolin‚ auxins(IAA)‚ cytokinins(CYT)‚ ethylene(ETH)‚ and gibberellins(GA) and each has a different purpose. Auxins will control cell elongation‚ cytokinins promote the act of cell division‚ ethylene causes the ripening of fruit‚ and gibberellins will elongate

Objectives: To use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions:

The Nissan Leaf is the first to enter the all-electric vehicle market. However‚ due to the current recession and the research and development costs put into designing the Leaf‚ our financial performance has been declining. Furthermore‚ there is still a lack of consumer faith in all-electric vehicles due to unsuccessful launches of other electric vehicles and competitors are ready to launch their own all-electric vehicle models. Our main objectives are to increase awareness of the leaf and attain
