《Stability and Antioxidant Activity of Anthocyanins from Flowers of Rhododendron pulchrum Sweet.》
3.1.4 Effects of oxidant and reducing agents on the stability of anthocyanins from flowers of R.pulchrum.As shown in Table 1，different redox agents in the test showed different degrees of damage to the stability of the anthocyanins.Among them，the most influential one was H2O2.The preservation rate was only 34.9%，and the color turned light yellow.Vc had the lest effect on the absorbance of the anthocyanins，and the color did not change much.When Na2SO3was added，the color of the anthocyanins gradually faded to orange.It indicated that the anthocyanins from flowers of R.pulchrum had poor anti-oxidant and anti-reducing capacity.When using anthocyanins，they should be avoided from contacting with oxidizing or reducing substance.However，adding a small amount of Vc had little effect.
