용도

용도

3,4-Dihydroxybenzoic Acid is a metabolite of polyphenols such as Phloretin (P339000) and Quercetin (Q509500).

일반 설명

Protocatechuic acid belongs to the class of polyphenolic compounds, which can be generally isolated from the dried flower of roselle. It can serve as a potential candidate possessing anticancer property, which can be involved in suppressing the growth of human promyelocytic leukemia HL-60 cells.
