- •
Four sesquiterpenes and three triterpenes were isolated from Scorzonear divaricata.
- •
Their structures were elucidated by spectroscopic data and X-ray crystallography.
- •
A tirucallane triterpene showed cytotoxic activity against four tumor cell lines.
- •
Two sulfated guaiane sesquiterpenes showed activity against ABTS cation radicals.
- •
Sulfated guaianes occur mainly in the Lactuceae tribe of Asteraceae family.
