SESQUITERPENE AND DITERPENE DERIVATIVES FROM SOLIDAGO SPECIES

Article abstract of DOI:10.1016/S0031-9422(00)83939-4

The investigation of four Solidago species afforded, in addition to known compounds, four new caryophyllene derivatives, two eudesmanes, two abietanes, a clerodane, two labdanes, three kauranes and an anol angelate.The structures were elucidated by spectroscopic methods and by some chemical transformations.While the diterpenes isolated are widespread in the genus Solidago, the sesquiterpenes have not been obtained before from any species.The overall picture of the large genus, however, is relatively uniform. - Key Word Index: Solidago odora; S. namoralis; S. canadensis; S. rugosa; Compositae; new sesquiterpenes; new diterpenes; new anol derivative; caryophyllene eudesmane, clerodane, labdane, kaurane and abietane derivatives.
