The Alkaloids of Crotalaria spectabilis Roth
Australian Journal of Chemistry, 1957Monocrotaline and a new alkaloid, spectabiline, are isolated from Crotalaria spectabilis Roth. in nearly equal amounts. Spectabiline is shown to be an O-acetylmonocrotaline and has been prepared by acetylation of monocrotaline.

The Toxicity of Crotalaria Spectabilis Seeds for Quail
The Journal of Wildlife Management, 1941Crotalaria as a cover crop is gaining attention in our country's conservation program. This genus of the legume or pulse family consists of more than 600 species. Of this number at least six are known to be very toxic to cattle, sheep, and horses, namely, C. sagittalis, C. juncea, C. burkeana, C. dura, C. globifera, and C. spectabilis.

Effects of Shading and Temperature on Showy Crotalaria (Crotalaria spectabilis)
Weed Science, 1982Showy crotalaria (Crotalaria spectabilisRoth) was grown in a controlled-environment greenhouse with a day/night temperature of 32/26C at full sunlight and under 40, 60, or 90% shade. Shading significantly reduced height, dry-matter accumulation, leaf production, leaf-area expansion, axillary-branch development, reproductive development, and the ...

Crotalaria spectabilis toxicity in swine: Characterization of the renal glomerular lesion
Journal of Comparative Pathology, 1975Abstract Eighteen feeder pigs each received a cumulative dose of 84 g. of ground Crotalaria spectabilis seeds in 43 days. Varying degrees of lack of thrift were seen in all pigs. During the experiment 2 pigs died from crotalaria poisoning. The survivors were necropsied in 2 groups, 70 and 90 days after the experiment began.

Seed Coat Impermeability and Germination of Showy Crotalaria (Crotalaria spectabilis) Seeds
Weed Science, 1979Showy crotalaria (Crotalaria spectabilisRoth) seed dormancy was due to seed coat impermeability to water. The seed coats became impermeable during later stages of maturation on the plant. When incubated immediately after harvest, 9% of the mature, black seeds (11% water content) imbibed water and germinated.

Modelling of the supercritical fluid extraction of monocrotaline from Crotalaria Spectabilis
The Journal of Supercritical Fluids, 1989Abstract In our extractions of Crotalaria spectabilis with supercritical carbon dioxide and carbon dioxide-ethanol mixtures, we observed history-dependent extraction, possible monocrotaline-lipid fluid phase repulsive interactions and cosolvent retention-release phenomena.

Untersuchungen zum experimentellen pulmonalen Hochdruck durch Samen von Crotalaria spectabilis
1972Die Toxizitat des Samens von Crotalaria spectabilis fur eine Anzahl von Tierspezies ist schon lange bekannt (2,10). Neal und Mitarb. (8) konnten 1935 als wirksames Prinzip ein Alkaloid isolieren, das den Namen Monocrotalin erhielt und dessen Struktur 1939 von Adams und Rogers (1) aufgeklart wurde.

Hypercholeresis in turkeys following the ingestion of Crotalaria spectabilis seeds.
The Cornell veterinarian, 1976Young female turkeys received diets containing Crotalaria spectabilis seeds for 18 weeks. Mean values for total bile flow, biliary bile acid excretion, bile acid-dependent flow and bile acid-independent flow were significantly higher in crotalaria-fed turkeys than in controls. The hypercholeresis observed in crotalaria-fed birds involved both bile acid-
