[Isolation and identification of terpenoides and anthraquinones from Euphorbia fischeriana].

In this paper, two terpenoides and one anthraquinone are isolated from the roots of Euphorbia fischeriana. Their structures are indentified by combination of physical constants and spectrum analysis as boehmerone (I), ent-16a, 17-dihydroxy-atisan-3-one (II) and physcion (III). They are found in the plant for the first time.
