Infobox references

Tomatine is a 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][3] Tomatine as well as the a-glycone derivative Tomatidine have been shown to have multiple health benefits.[4] Tomatine has antimicrobial properties against certain classes of microbes although some microbes produce an enzyme called tomatinase which can degrade tomatine, rendering it ineffective as an antimicrobial.[5]

Uses

Tomatine has been used as a reagent in analytical chemistry for precipitating cholesterol from solution.[1][6] Also, tomatine is known to be an immune adjuvant in connection with certain protein antigens.[7]
