Anthocyanin Purification using AB-8 Resin

Anthocyanin was extracted in our previous study in the condition of 19 min of ultrasound assistance, a liquid‐to‐solid ratio of 1:22 (g/mL), and hydrochloric acid volume fraction of 0.63% (Chen et al., 2022 ). In this experiment, AB‐8 macroporous resin was used to purify anthocyanin after the extracting solution was concentrated by a rotary evaporator (BUCHI V‐850, Switzerland). Before use, macroporous resin was pretreated according to the previously described methods (Lin et al., 2012 ; Wang et al., 2019 (link)).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
