Hederasaponin B has antiviral activity, via inhibiting the viral VP2 protein expression and blocking viral capsid protein synthesis. It also has antitumor activity, and it inhibits the superoxide generation induced by arachidonic acid (AA).

Apigenin is a potent inhibitor of CYP2C9, which has anti-inflammatory, antiangiogenic, and anti-cancer effects, it may inhibit EV71 replication through suppressing viral IRES activity and modulating cellular JNK pathway.

Corydaline is an acetylcholinesterase inhibitor, is also an inhibitor of CYP2C19 and CYP2C9. Corydaline has antiallergic, and antinociceptive activities. Corydaline promotes gastric emptying and small intestinal transit and facilitates gastric accommodation. Corydaline is an isoquinoline alkaloid and a member of isoquinolines.

Ganoderic acid Y significantly inhibits the replication of the viral RNA (vRNA) of EV71 replication through blocking EV71 uncoating.
