Which method is best for extracting chlorophylls a and b into solution?

10 March 2014 1 270 Report

I want to know the most reliable extractant for chlorophylls a and b.

Does the nature of the material (e.g algal cells, plant leaves) affect the type of extract to use? Because I used 90% ethanol to extract chlorophyll from some leaf samples and got a consistent reading.
