Sang, S., Cheng, X., Zhu, N., Stark, Re., Badmaev, V., Ghai, G., Rosen, R.T., Ho, C.T.

One new iridoid glycoside (defensive compounds produced by plants) and five known flavonol glycosides (which function as antioxidants) were isolated from the leaves of Morinda citrifolia. Their antioxidant (free radical scavenging) potential was measured, and all compounds showed antioxidant activity.
