Common Name | Tomatine |
---|
Description | Tomatine is a mildly toxic glycoalkaloid or glycospirosolane (steroidal alkaloids whose structure contains a spirosolane skeleton) found in the stems and leaves of tomato plants as well as in the fruit of unripened (green) tomatoes (up to 500 mg/kg). Red, ripe tomatoes have somewhat reduced amounts of tomatine. A toxic dose of tomatine for an adult human would appear to require the consumption of at least 500 g of tomato leaves in one sitting (“Toxic Plants of North America” (Iowa State University Press, 2001)). Tomatine is known to have fungicidal and antimicrobial properties and is likely produced by tomato plants as a defense against bacteria, fungi, viruses, and insects (PMID: 19514731 ). Some microbes produce an enzyme called tomatinase which can degrade tomatine, rendering it ineffective as an antimicrobial (PMID: 18835993 ).Tomatine has historically been used as a reagent in analytical chemistry for precipitating cholesterol from solution (PMID: 4362143 ). When lab animals ingest tomatine, essentially all of it passes through the animal unabsorbed. Tomatine apparently binds to cholesterol in the digestive tract, and the largely insoluble combination is excreted — ridding the body of both the alkaloid and cholesterol. Experiments with hamsters have shown that both tomatine-rich green tomatoes and purified tomatine can substantially lower the levels of undesirable LDL cholesterol while maintaining norma |
