Ortega, A.,Morales, F. J.,Salmon, M.
, p. 1850 - 1852 (1985)
Two kaurene type diterpenes were isolated from the aerial part of Stevia eupatoria.Their structures and stereochemistry were established by carbon and 1H NMR, chemical transformation and correlation with known compounds. Key Word Index - Stevia eupatoria; Compositae; Eupatoriae; kaurenes; 12β-ethoxy-ent-kaur-9(11),16-dien-19-oic acid; 12α-hydroxy-ent-kaur-16-en-19-oic acid.
