Chloroplasts are the organelles responsible for photosynthesis. In photosynthesis research, it is often necessary to use isolated chloroplasts for downstream studies. The pigments contained in chloroplasts mainly fall into two categories: chlorophylls (including chlorophyll a and chlorophyll b) and carotenoids (including carotenes and xanthophylls). They bind to proteins on the thylakoid membrane to form pigment-protein complexes. Among them, chlorophyll is also known as chloroplast pigment.The extraction principle of Chlorophyll Extraction Reagent is that chlorophyll is insoluble in water but soluble in organic solvents. This reagent is used for the crude extraction of chlorophyll with organic solvents, mainly for the extraction of chlorophyll from plant tissues and the determination of chlorophyll content.This reagent is for research use only and is not suitable for clinical diagnosis or other applications.ComponentsC1518212Component500 mLStorageC1518212AChlorophyll Extraction Reagent500 mLRT.C1518212BExtraction Powder3 gRT.Materials Provided by User1.

Take fresh leaves of spinach or other plants, wash and blot dry, remove the midribs. Weigh 0.1 g of cut fresh sample into a mortar or homogenizer. Mix at a ratio of 0.1 g (cut sample): 50 mg (Reagent B): 1 mL (Reagent A), then grind or homogenize into a liquid.2. Transfer the homogenate to a 10 mL centrifuge tube. Rinse the mortar or homogenizer several times with a small amount of Chlorophyll Extraction Reagent (Reagent A), and pour all rinsing solution and residue into the 10 mL centrifuge tube. Add Chlorophyll Extraction Reagent to a final volume of 10 mL, mix well, and keep in the dark for 5 min-2 h.Note: For large‑scale chlorophyll extraction, scale up the volume according to the ratio of adding Chlorophyll Extraction Reagent to 10 mL per 0.1 g of tissue.3.
