Infobox references

Tomatine is a toxic glycoalkaloid found in the stems and leaves of tomato plants, which has fungicidal properties.^[1] Chemically pure tomatine is a white crystalline solid at standard temperature and pressure.^[2] Some microbes produce an enzyme called tomatinase which can degrade tomatine, rendering it ineffective as an antimicrobial.^[3]

Uses

Tomatine has been used as a reagent in analytical chemistry for precipitating cholesterol from solution.^[1]^[4] Also, tomatine is known to be an immune adjuvant in connection with certain protein antigens.^[5]
