EVALUATION OF THE ANTIOXIDANT PROPERTIES OF A METHANOLIC EXTRACT FROMJUICE-PLUS-FRUIT AND JUICE-PLUS-VEGETABLE (DIETARY-SUPPLEMENTS)

The antioxidant properties of methanolic extracts from 'Juice Plus fru it' and 'Juice Plus vegetable', which are sold in capsule form as diet ary supplements, were evaluated using a range of established in vitro antioxidant assays. The values are compared to representative extracts from equivalent amounts (by dry weight) of selected fruits and vegeta bles prepared by the same method. Although there are some differences between the results of each assay, in general Juice Plus performed abo ut equally to the fresh fruit and vegetables on a dry weight basis. Th is implies that, based on in vitro assays to measure antioxidant poten tial, one capsule of 'Juice Plus fruit' or 'Juice Plus vegetable' (wei ghing 1 g) is equivalent to about 10 g (fresh weight) of fruit or vege table.
