Euphorbia is the largest genus of the family Euphorbiaceae with about 1600 species. All species of Euphorbia exude a milky juice when broken, and Euphorbia hirta’s local name “gatas-gatas” derives from this.
Gatas-gatas is a slender-stemmed, annual hairy plant with many branches from the base to the top, the branches simple or forked and ascending or spreading, up to 40 centimeters tall, reddish or purplish in color. Leaves are opposite, elliptic-oblong to oblong-lanceolate, distichous, 1 to 2.5 centimeters long, usually blotched with purple in the middle, toothed at the margin. Involucres are numerous, purplish to greenish in color, borne in dense, axillary, stalkless or short-stalked clusters or crowded cymes, about 1 millimeter in length. Capsules are broadly ovoid, hairy, three-angled, about 1.5 millimeters long.
– Abundant throughout the Philippines, in waste places, open grasslands, etc.
– Studies have isolated gallic acid, quercetin, triacontane, cetyl alcohol, phytosterol, phytosterolin (phytosterol glucoside); jambulol, melissic, and a mixture of acids consisting chiefly of palmitic, oleic, and linoleic acid.
– Phytochemicals screenings have yielded alkaloids, essential oil, phenols, sterol, flavones and fatty acids.
– Yields flavonoids: euphorbianin, leucocyanidol, camphol, quercitrin and quercitrol.
