New methods developed to detect, measure potato phytonutrients
Date:5/19/2010

This release is available in Spanish.

Potatoes come in all shapes, sizes and colors-including tubers with red, yellow, orange and purple flesh. This diversity also applies to phytonutrients, Agricultural Research Service (ARS) scientists in Prosser, Wash., are discovering.

Together with colleagues, they've devised new analytical procedures for rapidly detecting and measuring phytonutrient concentrations in the tubers. Phytonutrients are plant compounds that are of particular interest for their potential to help diminish the risk of cardiovascular disease, respiratory problems and certain cancers, note Roy Navarre and Chuck Brown, geneticists with the ARS Vegetable and Forage Crop Research Unit in Prosser.

Using the new analytic methods, Navarre and Brown profiled the phytonutrient contents of several hundred lines of wild and cultivated potato. For example, their analysis of phytonutrients known as phenolics showed concentrations that ranged from 100 to more than 1,500 milligrams per 100 grams dry weight in the potatoes.

One type of phenolic, called chlorogenic acid, is being tested by university cooperators for its potential to lower blood pressure. Also of interest are potatoes with high antioxidant activity, which is credited with helping neutralize cell-damaging molecules in the body called free radicals. Some potatoes boast antioxidant levels that rival vegetables such as spinach, Navarre reports.
