About Violaxanthin

Violaxanthin is a natural lutein pigment and a synthetic precursor of the plant hormone abscisic acid.

Violaxanthin is biosynthesized by zeaxanthin through epoxidation.

Violaxanthin is a natural pigment found in most fruits and vegetables, such as pansies.

Its molecular formula is C40H56O4, and its CAS number is 126-29-4.

MS-based technical means can realize the qualitative and quantitative analysis of violaxanthin.

  • Sample mixed
  • In order to ensure the accuracy of the samples and reduce systematic errors during sampling, it is necessary to select more than 3 materials with the same condition for each sample. (The same condition refers to the same period, basically the same phenotype, and the same part.)

  • Sample storage and transportation
  • Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature.

    Transport on dry ice (The sample transportation consumes about 3 ~ 4 kg / day, please use sufficient dry ice for transportation).

* There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information.

Feedback to Customers

  • A detailed technical report will be provided at the end of the entire project, including experimental procedures and instrument parameters.
