Studies of Physalis alkekengi L. fruits as a source of xanthophylls

Abstract

The studies reported here established that fruits of the perennial and quite hardy plant Physalis alkekengi grown in the conditions of the Belgorod area accumulate zeaxanthin (and β-cryptoxanthin) derivatives at levels of up to 20 mg/g of husks, which are needed for the prevention of age-related visual loss. Furthermore, attention is drawn to the berries of this Physalis species, which can be used in foods as a source of zeaxanthin (about 0.30 mg per berry).
