- 24 June 2000
The essential oil profile of Callicarpa americana was examined, and the oil was selectively toxic toward the cyanobacterium Oscillatoria perornata and the green alga Selenastrum capricornutum, with complete growth inhibition at 28.5 microgram/mL.

Phthalides and monoterpene hydrocarbons were determined to be good systematic markers or chemical fingerprints for A. sinensis and A. archangelica root oils and deterred the biting of two mosquito species more effectively than DEET.
A new 2D-TLC bioautography method for the discovery of novel antifungal agents To control plant pathogens.
A new bioassay has been developed combining the simplicity of direct bioautography with the improved chromatographic resolution of 2D-TLC for the discovery of new natural products with activity against agriculturally important fungal pathogens.
