Studies
• Antioxidant: A 2006 study of commonly
consumed roots crops in the Philippines – Kamote (Ipomoea
batata); ubi, purple yam (Dioscorea
alata); cassava (Manihot esculenta); taro or gabi (Colocasia
esculenta); carrot (Daucus carota); yacon (Smallanthus sonchifolius)
showed them to be rich sources of phenolic compounds with antioxidant
acitivity, highest in sweet potato, followed by taro, potato, purple
yam and lowest in the carrot.
• Anticonvulsant:
A study showed potato juice exerted significant anticonvulsant activity
in mice. It suggests that potato juice, as well as potato, may influence
brain GABA-activity.
• Teratological and Toxicological Studies:
Study was done onn the effects of acute and chronic administration in pregnant and non pregnant rats of alkaloidal, glycoalkaloidal and phenolic compounds from Solanum tuberosum. None of the compounds produced nueral tube defects; a few fetuses had rib abnormalities.
• Antiobesity of New Purple Potato Variety:
Study of a purple potato variety showed anti-obesity potential via inhibition of lipid metabolism through p38 MAPK and UCP-3 pathways.
• Anti-Adhesion / Antimicrobial Properties: A study showed S tuberosum has the potential of interfering with the adhesion of oral bacteria. Also, S tuberosum methanolic extract showed a greater then 25 mg/ml MIC value against S epidermis, S typhi and B subtilis.
