Sweroside possesses wound healing, cytoprotective, skin-whitening , anti-osteoporotic , and hepatoprotective effect. It can inhibit potent melanogenesis in melan-a cells at 300uM without cytotoxicity, also decreases tyrosinase, tyrosinase-related protein-1 (TRP-1) and TRP-2 protein production in melan a cells. It also shows insulin-mimicking effects on the regulation of Pck1 expression.
Aucubin is an iridoid glycoside with a wide range of biological activities, including pancreas-protective, chondroprotective, antispasmodic, liver-protective, anti-inflammatory, anti-microbial, antioxidant, anti-algesic as well as anti-tumor activities. Aucubin prevents neuronal death in the hippocampal CA1 region in rats with diabetic encephalopathy, it also has protective effects on H2O2-induced apoptosis in PC12 cells. Aucubin may improve obesity-induced atherosclerosis by attenuating TNF-α-induced inflammatory responses. Aucubin suppresses hepatitis B viral DNA replication in vitro.
