Quantification of Anthocyanin Content    

How to cite Favorites 2 Q&A Share your feedback Cited by


Anthocyanins are a class of flavonoids and important plant pigments. They attract insects to pollinate flowers, protect plants from UV irradiation, and act as antimicrobial agents against herbivores and pathogens. Biosynthesis of anthocyanin is stimulated by diverse developmental signals and environmental stresses including drought, wounding, pathogen infection and insect attack. Plant hormones such as jasmonates, a stress-related plant hormone, also induce accumulation of anthocyanins. Sensitivity of plants to these stress stimuli can be measured by accumulation of anthocyanins. Here we describe a simple method for measurement of anthocyanins in Arabidopsis thaliana seedlings. Amount of anthocyanins are calculated only from absorbances at 530 and 657 nm of crude extract.

Materials and Reagents

  1. Arabidopsis thaliana seedlings (~10 days after germination)
    Note: Amount of anthocyanin per seedling weight is higher in young seedlings.
  2. Bleach solution
  3. Sterile dH2O
  4. Methanol
  5. Acetic acid
  6. Murashige and Skoog medium salt (Wako Pure Chemical Industries, catalog number: 392-00591 )
  7. Sucrose
  8. 2-Morpholinoethanesulfonic acid (MES)
  9. Agar (for plant culture)
  10. Modified Murashige and Skoog medium (see Recipes)
  11. Extraction buffer (see Recipes)


  1. Paper towel
  2. Spectrophotometer
  3. Microcentrifuge
  4. Microcentrifuge tubes
  5. Mortar and pestle
  6. Liquid nitrogen
  7. Electric balance


  1. Add bleach solution to Arabidopsis thaliana seeds and shake gently for 7 min.
  2. Rinse three to five times with sterile dH2O.
  3. Sow surface-sterilized seeds on modified MS medium.
  4. Grow the plants under long day (16 h light/8 h dark) or continuous light condition (50~70 µmol/m2/s) at 22 °C for 7~10 days.
  5. Measure fresh weight of 10~15 seedlings.
    Note: Remove surface moisture with paper towel before measurement.
  6. Freeze seedlings with liquid nitrogen and grind in a mortar and pestle.
  7. Add 5 volumes (based on fresh weight) of extraction buffer and mix thoroughly.
  8. Centrifuge at 12,000 x g for 5 min at room temperature.
  9. Transfer supernatant to new tube.
  10. Centrifuge at 12,000 x g for 5 min at room temperature.
  11. Transfer supernatant to new tube.
  12. Measure absorbances at 530 and 637 nm.
  13. Calculate anthocyanin content (Abs530/g F.W.) by [Abs530 - (0.25 x Abs657)] x 5.
    Note: To correct contribution of chlorophyll to the absorbances at 530 nm, the formula Abs530 - (0.25 x Abs657) was used. Multiplication of “5” can be changed depending on volumes of added extraction buffer in step 5. For example, if 10 volumes of extraction buffer was added, multiply “10”.


  1. Modified Murashige and Skoog medium
    1x Murashige and Skoog medium salt
    0.5% Sucrose
    0.05% MES
    Adjust pH to 5.7 with KOH
    0.8% agar
  2. Extraction buffer
    45% methanol
    5% acetic acid

Did you mean absorbance at 637 or 657? Nakata et al stated 637 but cites ( to continue the horrible habit of some authors to cite protocols instead of just putting two more sentences and have a clear material and methods section) Matsui et al 2000 who cites Laby et al 2000 (who species 657 nm and cites Rabino et al., stating 657 nm)....... a broken phone game here...

dear authors,

I would like to ask about what kind of Volume do we use that you mention in the 7th step of procedure ?
secondly, based on the calculation, the result will be in Abs530/g F.W. would you mind to exemplify this ?

many thanks

best regards
