In the single-step procedure, 8 ml of a 21 chloroform-methanol (v/v) mixture was added to . 2. 333 grams of powdered dry leaf would be placed in a bowl, pressed down to make it as flat as possible. The more powdered the leaf, the less acetone would be needed. Perhaps the contamination came from equipment and laboratory wipe-downs since acetone is a commonly used cleaning agent within analytical labs or extraction facilities. Moisture for whole peppers, shells and seeds was analyzed using an oven drying method (65C, 24 hours). 3000ml of acetone would be poured onto the leaf, and the crushed leaf would be soaked for 5 minutes, while stirred enough so that the acetone worked its way through all the leaf. At this pH anthocyanins are typically pale or colorless.

The specific steps were as follows: the algae in . Also acetone possesses both polar and non-polar character making it a good candidate for a wash--and a poor candidate for active cannabis compound selectivity (IE it pulls everything out, not just what you want). The solvent will float on top of the extract and can be removed by syringe or by freezing the water and pouring off the solvent. Principal component analysis showed that little of the variation in the data was a result of technical issues, thus demonstrating that the TCA-acetone extraction is a reliable method for preparing aphid proteins for a quantitative proteomics experiment. It is hence possible to use water for analysis to zero the method. 1. Linearity of calibration curves, instrument limits . 1.1 This test method covers the determination of the amount of acetone-soluble matter in molded or laminated phenolic products.
