Fritillaries are produced in the tropics and subtropics, and grow widely in Southeast Asia, and in China's southern China, such as Guizhou Province, has rich resources of wild and cultivated fritillaries.

Rattanone in the natural world species is not stable, easy oxidative degradation and photolysis. In general, its toxic components decompose in 5 to 6 days, and in the sunny summer, it takes only 2 to 3 days.

Rattanone is also easily degraded in soil and water. The half-life is only 1-3 days. Because of its short half-life, easy decomposition and non-pollution of the environment, rotenone is commonly used in crop pest management and fish pond cleaning all over the world, and is regarded as a kind of natural, low-toxicity and high-efficiency pesticide.

Moderately toxic, oral LD50 in rats 132mg/kg.

Fisetinone is a kind of mitochondrial inhibitor, can inhibit mitochondrial electron transfer, is a commonly used insecticide, fisetinone's entry into the body of the insect to inhibit the mitochondrial respiratory chain, leading to the pest to appear respiratory systemic disorders such as respiratory difficulties and convulsions, slow action, paralysis and death.
