Studies of Physalis alkekengi L. fruits as a source of xanthophylls
- 65 Downloads
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).
