Icariside F2 shows modest α-glucosidase inhibitory (4.60±1.74% to 11.97±3.30%) and antioxidant activities. It also displays potent NF-κB inhibitory effects, with the IC50 value of 16.25 ± 2.19 uM.
Kaempferol-3-O-α2-D-(6''-O-coumaryl) glycoside has antioxidant activity and α±-glucosidase inhibitory effects, it could potentially be used for food additives and the development of useful natural compounds.
Tachioside has antiobesity, antioxidant and α-glucosidase inhibitory activities, it decreases lipid content in 3T3-L1 adipocytes by inhibiting lipogenesis, shows antiobesity activities. Tachioside can inhibit nitric oxide production in lipopolysaccharides-stimulated RAW 264.7 cells with IC50 value of 12.14 μM.
Tuberosin shows anti-inflammatory and antioxidant activities.It demonstrated a significantly potent inhibition on yeast α-glucosidase in a dose dependent manner.
