The alkaloids of Rauwolfia serpentina benth
TL;DR: Active chemical and pharmacological interest in R. serpentina has resulted in the discovery of several new alkaloids, and the isolation by Muller, Schlittler, and Bein of reserpine, an alkaloid with pronounced hypotensive and sedative activity, has lent further impetus to the pharmacological and chemical study of the alkal steroids of R. Serpentina.

TL;DR: All compounds showed no cytotoxicity against five human cancer cell lines, human myeloid leukemia, hepatocellular carcinoma, lung cancer, breast cancer, and colon cancer cells.
Journal ArticleDOI
The Rauwolfia alkaloids.
TL;DR: Although rauwolfia may ultimately not survive to take its place alongside the solanaceous drugs, the cardiac glycosides and opium, a study of its properties seems likely to lead to a clearer understanding of the complex mechanism underlying hypertensive disease in man.
