Three new indolinic alkaloids have been isolated from the root bark of Strychnos variabilis: strychnopivotine, unusual because the C17 atom of the curane skeleton is lacking, 16-hydroxyisoretulinal and rosibiline, a derivative of N-desacetylretuline. Their structures were deduced from spectral data and that of rosibiline was confirmed chemically
