Introduction to Trace Environmental Quantitative Analysis (TEQA)
Published in Paul R. Loconto, Trace Environmental Quantitative Analysis, 2020
Yes indeed! Recent work at the CDC demonstrates how exposure to the plant-based toxic proteins ricin (derived from the castor bean) and abrin (derived from the rosary pea) can be evaluated in human plasma based on quantifying their metabolites ricinine and abrine.14 Molecular structures for these analytes are shown below:

Castor oil is a multi-purpose vegetable oil made by extracting oil from the seeds of the Ricinus communis plant. Castor seeds are known as castor beans which contain a toxic enzyme called “ricin.” Castor oil has the number of medicinal, industrial and pharmaceutical uses. It is commonly used as an additive in foods, medication and skincare products, as well as an industrial lubricant and biodiesel fuel component.[10] The ricin and ricinine are active ingredients of R. communis that act against S. frugiperda. Castor seed extract possesses more insecticidal and insectistatic potential than the leaf extract.[11] Castor and Hazelnut oil have shown insecticidal activity against various pest and insects.[12,13] The seeds of R. communis are economical, readily available and biodegradable. The use of nanopesticides prepared by such materials would be a good alternative strategy for controlling pest populations and reducing the toxic effect of bulk formulations on the environment.[14] The bioactive nanoemulsion prepared by using Lippia alba volatile oil was also found to be effective pesticide.[15]

From castor seeds is extracted 45–50% oil [108]. The meal, a coproduct after oil extraction, has been used worldwide as an organic fertilizer due to its high nitrogen and phosphorus content [109]. Although it presents high protein content, toxic factors in the castor cake, such as ricin, ricinine, and allergen, prevent its use as animal feed [110]. However, after a detoxification process, castor cake can be used as feed for sheep [111] and cattle [112]. While many methods may enable the use of castor cake as animal feed, industrial technologies are expensive, operationally infeasible, and do not ensure the detoxification of the product [113].

The fruits collected were sun-dried during 24 h for obtaining the castor seeds by shelling. The seeds were heated with water at 100 °C for 60 min for releasing the toxins ricin and ricinine. Then, the castor seeds were dried in convective flow stove (FELISA FE-291AD) at 60 °C for 24 h for removing the moisture [21–24].
