Abstract
The black wolfberry (Lycium ruthenicum) belongs to the Solanaceae family. The genus Lycium comprises 87 recognized species and is distributed in arid and semi-arid regions of temperate to subtropical zones in the world. At present, China is the greatest global producer and supplier of wolfberry products. The goji berry has recently became one of the most popular fruits in Turkey due to its health-beneficial compounds such as phenolic compounds (phenolic acids and flavonoids), carotenoids, tocopherol, ascorbic acid and antioxidant properties. Lycium fruits have been used as a remedy since ancient times in Asian countries, especially in China, for their emmenagogue, diuretic, antipyretic, tonic, aphrodisiac, hypnotic, and hepatoprotective effects. The purpose of this paper is to determine the biochemical characteristics (namely total phenolic and anthocyanin contents, as well as the total antioxidant capacity) of black wolfberries grown under the Aksaray ecological conditions.
Highlights
The fruit of Lycium spp., called Boxthorn, Matrimony vine, wolfberry or goji berry, is well-known for its anti-ageing and eyesight improving effects
Lycium barbarum produces red-coloured fruits called Fructus lycii, Gouqizi, goji berries or wolfberries, which have been used as a traditional Chinese herbal medicine for thousands of years (Xin et al 2011)
A study conducted in China established that the functional components of L. ruthenicum black fruits primarily consist of anthocyanins, essential oils and polysaccharides (Zheng et al, 2011)
Summary
İlbilge et al./ Deter. of the Total Phenolic and Anth. Contents, as Well as the Total Antiox. The radical scavenging activity could be calculated by using different standard solutions such as vitamin C (L-ascorbic acid), Trolox, vitamin E (α-tocopherol), BHT and BHE. They are rich in vitamins B and C, as well as polysaccharides These fruits have a high protein content (10 %) and provide 18 various amino acids, of which 8 are essential (Ionica, et al, 2012). Dithiothreitol (DTT), they determined that LBG exhibits cytoprotective effects for reducing stress by lowering the DTTinduced and caspase-3 activity These results suggest that AA2βG is an important antioxidant component of wolfberry fruits, which may share similar yet distinct antioxidant properties with. The present study is aimed at revealing the biochemical properties (namely the total phenolic and anthocyanin contents, as well as the total antioxidant capacity) of black wolfberries grown under the Aksaray ecological conditions
