Beschreibung
The principal source of rotenone is the tuber root of
Derris elliptica; however, it is also extracted from the
roots of Derris mallaccensis, Lonchocarpus utilis, and
Lonchocarpus uruca. Rotenone is both a stomach and
contact poison for arthropods. Its fast knockdown action
is attributed to decreasing the availability of nicotinamide
adenine dinucleotide to serve as a cofactor in various
biochemical pathways including the Krebs cycle, thereby
inhibiting the mitochondrial respiratory enzymes.
Chemische Eigenschaften
Rotenone is a colorless to red odorless crystalline solid; a white crystalline solid when pure; oxidation will cause yellowing to bright red coloring. Odorless.
Rotenone is related to isoflavonoid compounds derived from the roots of Derris spp., Lonchocarpus spp., and Tephrosia spp., found primarily in Southeast Asia, South America, and East Africa. The isolated compound is an odorless, colorless to red crystalline solid. It is insoluble in water and has a very low vapor pressure (U.S. EPA, 2007; HSDB, 2012a).
Verwenden
Rotenone is an broad spectrum insecticide that occurs naturally in seeds and stems of several plants. Rotenone was first registered in 1947 and is currently used exclusively to kill fish (U.S. EPA, 2007). In 2006, registrants voluntarily canceled all livestock, residential and home owner uses, domestic pet uses, and all other uses except for piscicide uses. Currently the main uses include fish management strategies to remove nonnative fish species from lakes, ponds, or streams and in catfish aquaculture prior to stocking ponds with with fry to remove undesirable fish species (U.S. EPA, 2006d).
Rotenone has been historically used by native people to paralyze fish for capture and consumption. Outside the United States, the compound is still used to control insects in fruit and vegetable cultivation and for control of fire ants and mosquito larvae in pond water (HSDB, 2012a).
Definition
ChEBI: A member of the class of rotenones that consists of 1,2,12,12a-tetrahydrochromeno[3,4-b]furo[2,3-h]chromen-6(6aH)-one substituted at position 2 by a prop-1-en-2-yl group and at positions 8 and 9 by methoxy group
(the 2R,6aS,12aS-isomer). A non-systemic insecticide, it is the principal insecticidal constituent of derris (the dried rhizome and root of Derris elliptica).
Allgemeine Beschreibung
Colorless to brownish crystals or a white to brownish-white crystalline powder. Has neither odor nor taste.
Air & Water Reaktionen
ROTENONE decomposes upon exposure to light or air. Insoluble in water.
Reaktivität anzeigen
ROTENONE is readily oxidized in the presence of alkalis. ROTENONE is incompatible with oxidizers. .
Hazard
Toxic by ingestion, overexposure can be
fatal, irritant to skin, eyes and upper respiratory
tract. Central nervous system impairment. Ques-
tionable carcinogen.
Health Hazard
Rotenone is an irritant and affects
the nervous system, causing convulsions.
Brandgefahr
Flash point data for ROTENONE are not available; however, ROTENONE is probably combustible.
Landwirtschaftliche Anwendung
Insecticide, Acaracide, Veterinary medicine: The use of rotenone as a pesticide to kill invasive fish species is currently the only allowable use of this pesticide. Rotenone is a selective, nonspecific botanical insecticide with some acaricidal properties, and has been used in agriculture to control insects on vine fruit, flowers and vegetables. Registered for use in the U.S.A U.S. EPA restricted Use Pesticide (RUP) due to acute inhalation, acute oral, and aquatic toxicity. Agricultural and residential uses and all food uses were voluntarily cancelled in 2006[83]. In 2006, registrants requested voluntarily cancellation of all livestock, residential and home owner uses, domestic pet uses, and all other uses except for pesticide uses. In 2011 the use of this pesticide chemical was linked to Parkinson’s disease. Not listed for use in EU countries.

Biologische Aktivität
Mitochondrial electron transport chain inhibitor (IC 50 = 1.7 - 2.2 μ M at complex I). Inhibits NADH oxidation by cardiac sarcoplasmic reticulum (IC 50 = 3.4 nM). Commonly used pesticide and induces Parkinsonism in animal models. Cell-permeable and brain penetrant.
mögliche Exposition
A potential danger to those involved
in extraction from derris root, formulation or application of
this insecticide. Rotenone is used as a pharmaceutical and
veterinary drug.
Carcinogenicity
In human lymphocyte culture assays
rotenone did not increase the frequency of
chromosomal aberrations or sister chromatid
exchanges but did cause an increase in the frequency
of binucleated micronuclei and a delay
in cell cycle.
Environmental Fate
Rotenone released to the atmosphere will exist as particulates due to the extremely low vapor pressure. Particulate-phase rotenone will be removed from the atmosphere by wet and dry deposition and may be degraded by direct photolysis. It is mobile to moderately mobile in soil and sediment and volatilization from soil surfaces is not expected to occur to any extent. If released to water, rotenone generally degrades quickly through abiotic (hydrolytic and photolytic) mechanisms, with half-lives of a few days to several weeks or longer depending on water temperature (U.S. EPA, 2007; HSDB, 2012a).
Rotenone has a relatively low potential for bioconcentration in aquatic organisms (Bioconcentration Factor (BCF) < 30X) (U.S. EPA, 2007).
Stoffwechselwegen
By hepatic microsomal incubations from rainbow trout
with 14C-rotenone, three major and several minor
metabolites of rotenone are observed, the major ones
being identified as rotenolone and two epimeric forms
of 6' ,7' -dihydroxyrotenone.

Inkompatibilitäten
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo-
sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides, and alkalies.
Waste disposal
Rotenone is decomposed by
light and alkali to less insecticidal products. It is readily
detoxified by the action of light and air. It is also detoxified
by heating; 2 hours @ 100 ? C results in 76% decomposition.
Oxidation products are probably nontoxic. Incineration has
been recommended as a disposal procedure. Burial with
lime would also present minimal danger to the environ-
ment . In accordance with 40CFR165, follow recommen-
dations for the disposal of pesticides and pesticide
containers. Must be disposed properly by following pack-
age label directions or by contacting your local or federal
environmental control agency, or by contacting your
regional EPA office.
