[more ▼] The potential cytotoxic activities of 46 alkaloids isolated from different Strychnos species were tested on different cancer or normal cells cultured in vitro. The authors use a relatively simple microtest which gives good reproducibility. Most of the active compounds belong to the usambarane skeleton but other structure-activity relationships are being discussed.

[more ▼] The authors give a survey of the known data and biological studies about the bark and the tincture of Guatteria gaumeri (Yumel). They describe not only methods of micrographic and chromatographic identification of the drug, but also a quantitative determination of the two main constituents: alpha-asarone ( propenylbenzene derivative) and guattegaumerine ( bisbenzylisoquinoleine alkaloid).

The main alkaloid (present in a minute amount) was identified to dolichantoside (TLC, UV, IR and CD) and compared to a reference ... [more ▼] The bark of Strychnos tricalysioides from Cameroon has been studied. The main alkaloid (present in a minute amount) was identified to dolichantoside (TLC, UV, IR and CD) and compared to a reference compound previously isolated in our laboratory from Strychnos gossweileri root bark.
