Aloesin 是芦荟的活性成分之一，能够通过 MAPK 信号通路发挥抗癌作用，并具有抗炎、紫外线保护和抗菌作用。

Aloesin is a C-glycosylated chromone compound found in aloe (Liliaceae) that inhibits tyrosinase (IC50 = 0.9 mM), an enzyme responsible for catalyzing the first step of the conversion of tyrosine to melanin.

Aloesin prevents not only UV-B-induced immune suppression, but also could be a positive pigment-altering agent for cosmetic application. In preclinical study, aloe extract was investigated using phagocytosis and nitroblue tetrazolium chloride (NBT) reduction in adult bronchial asthma.
