Aucubin, an iridoid glucoside, is isolated from Plantago asiatica, Eucommia ulmoides, the leaves of Aucuba japonica and more recently from butterfly larva. Aucubin has many biological activities, such as antioxidant, anti-aging, anti-inflammatory, antimicrobial, anti-fibrotic, anti-cancer, hepatoprotective, neuroprotective and osteoprotective effects^[1][2][3].

Aucubin (0.001-1 μg/mL; pretreated for 30 min) dose-dependently inhibits IgE-induced TNF-α and IL-6 production and expression in RBL-2H3 cells, with IC₅₀s of 0.101 and 0.19 μg/mL, respectively^[2].
Aucubin (0.01 μg/mL; pretreated for 30 min) inhibits IgE-induced nuclear translocation of p65 subunit of NF-κB and degradation of IκBα in RBL-2H3 cells^[2].
Aucubin (0.001-1 mM; 12 h) increases PC12 cellular viability and markedly inhbits H₂O₂-induced apoptotic cell death^[4].

Aucubin (5 mg/kg; i.p. for 15 d) has antioxidant and pancreas-protective effects on rats with streptozotocin-induced diabetes^[1].
Aucubin (40-200 mg/kg; a single i.p.) exhibits significant protective activity against α-amanitin intoxication in mice^[5].
Aucubin (5 mg/kg/day; i.p. for 21 d) decreases the breathing frequency, increases the lung dynamic compliance, alleviates lung parenchymal fibrotic changes, and reduces the intrapulmonary collagen disposition and inflammatory injury of BLM-stimulated mice^[6].
