 High Performance Liquid Chromatography (HPLC) Method for Analysis of Keracyanin, Delphinidin, Petunidin, Malvidin

Anthocyanins are a class of water-soluble pigments responsible for the red, purple, and blue colors found in many fruits, vegetables, and flowers. They belong to the flavonoid group of phytochemicals and have strong antioxidant properties.

Anthocyanins (Keracyanin, Delphinidin, Petunidin, Malvidin) can be retained, separated and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using Vis 530 nm.

UV-Vis Spectrum of Delphinidin

September 18, 2024
UV-Vis Spectrum of Delphinidin. Absorption Maxima: 206 nm, 274 nm, 536 nm.

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.
