The results of the chemical examination of the first 1,000 Iant samples received in a survey of plants &r steroidal sapogenins are reported. Data are given on 925 .samples, unidentified lots, 104 genera, and%%ilies. Quantitative data are given for the occurrence of 14 steroidal sapo enins. Qualitative results were obtained fTor flavonols, dkaloids, tannins, and unsaturated sterols. representing 292 identified s 335 ORTISONE was originally isolated from the c adrenal cortex. At present commercial cortisone is synthesized from certain bile acids of cattle. Since the supply of these is limited by the number of cattle slaughtered, a cheaper and potentially unlimited plant source of a suitable *
Vol. 76 allowed to stand at 0°for 24 hours. The orange needles, m.p. 126-130°, that separated were again chromatographed through an alumina layer in benzene and a free hydrocarbon was obtained from the effluent. This hydrocarbon failed to crystallize but gave a picrate of orange needles, m.p.133.5-134°, from alcohol (picrate of Xlla).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
