Rauwolfia canescens yields another alkaloid which possesses sedative and strong hypotensive activity. This newly isolated ester alkaloid has been termed 11- desmethoxyreserpine. Unlike reserpine, this alkaloid does not yield reserpic acid upon hydrolysis. The acid resulting as a hydrolysis product of 11-desmeth- oxyreserpine has been termed raunormic acid, whose physical properties differ markedly from those of reserpic acid. Acute oral, intraperitoneal, and chronic oral toxicity studies indicate that 11-desmethoxyreserpine exhibits in the test animal a favorable therapeutic index, thus assuring relative safety, warranting further pharmacologic and clinical studies.
The leaves of Rauwolfia nitida Jacq. have yielded two new indole alkaloids, raunitidine, an 11-methoxy-δ-yohimbine, and rauniticine, an isomer of ajmalicine.
