Extraction of rotenone and other insecticides from source plants. Grinda, Francoise; Gueyne, Jean (Saphyr S.a r.l., Fr.).Chemicals with cas numbers 34316-64-8 and 2035-99-6 also play role. PCT Int. Appl. WO 8303951 A1 24 Nov 1983, 16 pp. DESIGNATED STATES: W: DE, MG, US; RW: BE. (French). (World Intellectual Property Organization). CODEN: PIXXD2. CLASS: IC: A01N065-00. APPLICATION: WO 83-FR79 28 Apr 1983. PRIORITY: FR 82-8436 14 May 1982. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) The current methods of extn. of rotenone [83-79-4], pyrethrum, and other natural insecticides from their plant sources are enhanced by mixing the known solvents such as dialkyl phthalates, CH2Cl2, or CHCl3 at 10-70% with 90-30% of C8-20 aliph. acid esters with C1-16 alkyls or alkenyls. Thus, agitation of 100 g of derris powder with 25 g octyl stearate [109-36-4] + 160 g CH2Cl2 at 45° for 0.5 h, followed by removal of CH2Cl2 by distn., gave an ext. contg. 14% rotenone + 64% octyl stearate. The ext. was dild. to 7% rotenone and emulsified by a surfactant for spraying plants. .

Effect of injected rotenone on the production and composition of urine from the rainbow trout (Salmo gairdneri)

Effect of injected rotenone on the production and composition of urine from the rainbow trout (Salmo gairdneri). Erickson, D. A.; Gingerich, W. H. (Dep. Biol., Univ. Wisconsin, La Crosse, WI, USA). Aquat. Toxicol., 9(4-5), 263-74 (English) 1986. CODEN: AQTODG. ISSN: 0166-445X. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Renal function was evaluated in adult rainbow trout dosed with rotenone (I) [83-79-4] at 225 and 275 mg/kg. The chem. compn. of urine samples and urine flow rates collected over a 5-h pretreatment period were compared with hourly urine samples collected over a 5-h posttreatment period. Significant increases in osmolality and in concns. of Na, K, chloride, glucose [50-99-7], and total protein were obsd. in the urine of treated fish. Urine solute concns. reached max. 1-3 h after treatment and decreased thereafter, indicating that the effects were reversible. Concns. of Na and Cl- were highly correlated in 2-h posttreatment urine samples. Urine flow rates were reduced in trout at each dose of I but the decrease in vol. 7440-23-5 and 50-99-7 which are cas registry numbers of chemicals are mentioned. of urine voided was not dose-dependent. In a sep. study, [14C]polyethylene glycol was used as a filtration marker to det. the effect of I treatment (225 mg/kg) on urine flow rate, glomerular filtration rate, and renal water reabsorption. Posttreatment urine flow rates were reduced partly by reduced glomerular filtration and partly by increased water reabsorption. Transient increases in plasma osmolality and hematocrit also were obsd. 0.5 h after I treatment. .
