Foliar material of Hydrostachys insignis contains kaempferol 3-glucoside and kaempferol 3-sophoroside. Iridoids, proanthocyanidins, acteoside, alkaloids, hydrolyzable tannins (ellagic acid), cyanogenic glycosides, and saponins could not be detected. This chemical profile does not support proposed relationships between Hydrostachyaceae and either Podostemaceae or members of the Scrophulariales. It is proposed that the chemical profile of Hydrostachyaceae reflects phylogeny, not convergence to an aquatic habitat; but the profile does not suggest any accurate systematic alignment of Hydrostachyaceae.
