Icariin inhibits PDE5 and PDE4 activities with IC50s of 432 nM and 73.50 μM, respectively. Icariin also is a PPARα activator. Icariin has been reported to have anti-hypoxic, phytoestrogenic, anti-osteoporotic, anti-inflammatory, neuroprotective, and anti-depressant-like activities. Icariin is effective in the attenuation of AHR and chronic airway inflammatory changes in OVA-induced murine asthma model, and this effect is associated with regulation of Th17/Treg responses. Icariin inhibited NF-κB signaling activation and the NLRP3-inflammasome/caspase-1/IL-1β axis.

Ziziphin is a triterpene glycoside which exhibits taste-modifying properties and derives from the leaves of Ziziphus jujuba (Rhamnaceae). In a study, Ziziphin was up to 4 times more active in suppressing the sweet taste of sucrose than other anti-sweet constituents (Suttisri, 1995). Ziziphin suppressed the sweetness induced by D-glucose, D-fructose, stevioside, glycine, sodium saccharin, aspartame and naringin dihydrochalcone. Ziziphin however showed no uppressive effect on the sour taste of hydrochloric acid and the bitter taste of quinine, indicating that ziziphin is highly specific to the sweet taste (Kurihara, 1992). Ziziphin was found to inhibit the sweet taste receptors in humans (Smith, 1983) by a mechanism known as taste modification. In comparison with known gymnemic acids, effects suggest that net dissociation of ziziphins from taste receptor membranes and/or inactivation in the membrane may be much faster than with gymnemic acids (Mahajan, 2009).
