title: [Chemical constituents of Euphorbia nematocypha Hand.-Mazz].
abstract: Four compounds were isolated from the roots of Euphorbia nematocypha. Three of them were identified as A'-neogammacer-22(29)-en-3 beta-ol (18 beta.21 alpha) (II), jolkinolide E (III) and beta-sitoesterol (IV). Among them, II was obtained from the genus Euphorbia and III from this plant for the first time.
