The ethanol extracts of Wikstroemia foetida var. oahuensis and Wikstroemia uva-ursi showed antitumor activity against the P-388 lymphocytic leukemia (3PS) test system One PS-active constituent of both plants was the lignan wikstromol. Several inactive compounds were identified as daphnoretin,
An alcoholic extract of the seeds of Coronilla varia L. showed inhibitory activity against KB cells in culture and was fractionated through a series of partitions, column chromatography, and preparative layer chromatography to yield hyrcanoside, daphnoretin, scopoletin, and umbelliferone.
The in vitro P-388 lymphocytic leukemia activity of the chloroform-soluble fraction of the roots of Peddiea fischeri (Thymelaceaceae) was found to be due principally to the quinone 2,6-dimethoxybenzoquinone (2,6-DMBQ), and to a lesser extent the two coumarins daphnoretin and umbelliferone. This is
