Euphorbia helioscopia, the sun spurge, is a species of flowering plant in the spurge family Euphorbiaceae. It is a herbaceous annual plant, native to most of Europe, northern Africa, and eastward through most of Asia.[1][2][3]

Folk names include wart spurge, umbrella milkweed and madwoman's milk.[4]

Description

It is an annual plant growing in arable land and disturbed ground. It grows to 10–50 cm tall, with a single, erect, hairless stem, branching toward the top. The leaves are oval, broadest near the tip, 1.5–3 cm long, with a finely toothed margin. The flowers are small, yellow-green, with two to five basal bracts similar to the leaves but yellower; flowering lasts from mid-spring to late summer.[3][4]
Uses

It is highly poisonous. Active ingredients are extracted from it for use in pharmaceutical industry. It is also a plant used in Chinese traditional medicine.[5] Its extract has been found to inhibit hepatocellular carcinoma in vivo in mice[6] and in vitro in human cells.
Chemistry

Euphorbia helioscopia contains the jatrophone-type diterpenoids euphoheliosnoid A, B, C[7] and D[5] and other toxic diterpenes such as euphoscopins, epieuphoscopins euphornins, cuphohelioscopins and euphohelionone.[8]

Four esters of 12-deoxyphorbol (12-deoxyphorbol-13-phenylacetale-20-acetate, 12-deoxyphorbol-13-dodec-dienoate-20-acetate, 12-deoxyphorbol-13-[2-methyl-cis-2-butenoate]-20-acetate and 12-deoxyphorbol-13-[2-methyl-cis-2-butenoate]) can be isolated from the fresh aerial parts. These substances are the major skin irritants found in the plant.[9]

m-Hydroxyphenylglycine and 3,5-dihydroxyphenylglycine are two amino acids that can be isolated from the latex of E. helioscopia.[10]

Hydrolysable tannins can be found in E. helioscopia. Helioscopinin A (1,6-(S)-hexahydroxydiphenoyl-2,4-(S)-dehydrohexahydroxydiphenoyl-3-O-galloyl-β-D-glucose), helioscopinin B (1,6-(S)-hexahydroxydiphenoyl-3-O-galloyl-β-D-glucose), helioscopin A (1,6-(S)-hexahydroxydiphenoyl-2,4-(R)-elaeocarpusinoyl-3-O-galloyl-β-D-glucose) and helioscopin B (1,3,6-tri-O-galloyl-2,4-(R)-elaeocarpusinoyl-β-D-glucose) can be found together with eight other tannins: corilagin, punicafolin, geraniin, elaeocarpusin, furosin, terchebin, mallotusinin and carpinusin.[11] Helioscopinin-A shows anti-allergic and anti-asthmatic activities in guinea pigs. It is suggested that this compound exerts its activities through antagonism on leukotriene D4-induced responses.[12]
