Extracting the Chlorophyll


ΔS ≥ 0 |  rudescience

Chlorophyll is a term used for several closely related green pigments found in cyanobacteria and the chloroplasts of algae andplants. Its name is derived from the Greek words χλωρός, chloros (“green”) and φύλλον, phyllon (“leaf”).

Chlorophyll is an extremely important bio molecule, critical in photosynthesis, which allows plants to absorb energy from light. Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorbent of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.

One way of extracting Chlorophyll is by ethanol extraction (the safest). Plant material is slightly boiled in ethanol for a few moments and then filtered to reveal the green stuff extracted from your other green stuff. Chlorophyll is also fluorescent giving off a Red-ish color under UV light.
