Plantainoside D shows potent antioxidative effects as those of ascorbic acid, it shows angiotensin-converting enzyme (ACE) inhibitory inhibitory activity in vitro with the IC(50) value of 2.17 mM, it also shows inhibitory activity against PKCalpha with the IC50 value (in microM) of 14.8. Plantainoside D protects adriamycin-induced apoptosis in H9c2 cardiac muscle cells via the inhibition of ROS generation and NF-kappaB activation.

Curdione has anti-inflammatory, cancer chemopreventive activities, significant anti-platelet aggregation and antithrombotic activities , the inhibitory mechanism of curdione on platelet aggregation may increase cAMP levels and subsequently inhibit intracellular Ca2+ mobilization. plays an important role in the CYP3A4 inhibitory activity of C. aromatica.
