The family Droseraceae consists of four genera and about 100 species of perennial herbs, of which Drosera burmannii Vahl, Drosera rotundifolia L, Drosera indica L., and Drosera peltata Sm. are used in Asia for the treatment of cough. Naphthoquinones and flavonoids, which occur in this family, have not been fully studied for pharmacology, and it appears that flavonoids inhibit human neutrophil elastase, hence the potential for the treatment of inflammation. 

Drosera rotundifolia L., or round leaf sundew, is a little perennial herb that can reach 35 cm in height. The plant is found in temperate bogs and swampy areas. The leaves are simple, fleshy, broadly ovate and arranged into rosettes. The leaves are covered with sticky, shiney, red tentacles. The flowers are pink (Fig. 23).

A solution of 100 ml of diethyl ether containing 1% concentrated H2SO4 was mixed with 50 g of fresh Drosera rotundifolia. The mixture was macerated in a Waring blender and allowed to stand for 8 h. After filtration and evaporation, 50 ml of 2 M H2SO4 was added. The mixture was steam-distilled and the yellow distillate extracted with ether.
