Article abstract of DOI:10.1016/0031-9422(88)80772-6

In addition to four triterpenes previously found, 12 triterpenes were isolated from the whole herb of Euphorbia supina along with sitosterol.Nine of these were known triterpenes including fernane, simiarane and multiflorane skeletons.The remaining three were confirmed to be δ-amyrin formate, ferna-7:9(11)-dien-3β-ol and 11α,12α-oxidotaraxerol on the basis of chemical and spectroscopic evidence.Key Word Index--Euphorbia supina; Euphorbiaceae; whole herb; triterpenes; migrated hopanes; oleananes; migrated oleananes; taraxerane.
