IntroductionGoji berry is the common name of the species Lycium barbarum, Lycium chinense, and Lycium ruthenicum, belonging to the genus Lycium of the family Solanaceae, and it is known to occur more often in tropical and subtropical regions of the world (Levin and Miller, 2005). The plant is common in Mongolia, the Himalayas, western China, and Tibet (Bucheli et al., 2011), where it occurs in arid, semiarid, and slightly semisaline regions (Fukuda et al., 2001).Worldwide, goji berry is also known as wolfberry. While Lycium ruthenicum has small black berries, Lycium barbarum has various colored berries, ranging from orange to dark red. These 2 species are cultivated commercially, with studies having been conducted more often on Lycium barbarum. Goji berry is a bush-type perennial plant, which is highly tolerant to climatic and environmental conditions, that is able to uptake necessary nutrients and water from the soil due to its advanced root system. Although Lycium barbarum and Lycium ruthenicum have similar morphological properties, specific morphological properties are obviously characteristic in distinguishing these 2 species (Wang et al., 2015).In Lycium barbarum, the leaves are long and elliptical, pedicel is 1-2 cm long, calyx usually has 2 lobes that are 2-or 3-ribbed at the end, corolla tube is 8-10 mm long and longer than the lobes, and the berries are red or orange, yellow, rectangular, and oval. There are usually between 4 and 20 brown or yellow seeds per berry. Lycium ruthenicum is bushy like Lycium barbarum and it is rather branched. Leaves are fleshy, linear, or slightly cylindrical. Calyx is dispersed with 2-4 lobes, pedicel is 5-10 mm long, berries are spherical purple and black, sometimes its head or edge is notched, and the seeds are especially brown (Mi et al., 2015).Goji berry plants are highly tolerant to adverse environmental conditions and grow at different altitudes ranging from 700 to 2700 m. In China, the plant is very popular and it has been consumed as a food for centuries due to its many benefits for health and its effect on longevity (Gündüz et al., 2015).The berries, harvested from the beginning of summer to the end of autumn, are consumed either fresh or dried (Amagase and Farnsworth, 2011; Gundogdu et al., 2018). More recently, studies on the goji berries of the species Lycium have focused on potential health-benefitting Abstract: Goji berry is a lesser-known fruit species and its berries have been used in traditional medicine for centuries as remedies to treat eye, liver, and kidney ailments, as well as for the prevention of cancer symptoms due to its high phytochemical content. This study aimed to investigate changes in the pomological, biochemical, and phytochemical properties of the berries of 4 goji berry genotypes harvested during 4 months (June, July, August, and September) of the same year. The results indicated that the highest berry dimensions (height and width) and soluble solid content were obtained from Genotype 2, harvested in June. The vitamin C, total phenolic, an...

“…Goji fruit has been often referred to as supply for several minerals. Kafkaletou et al [10] found berry of Goji cultivated in Greece a significant source of K irrespective of variety. Niro et al [13] has declared dried Goji berries as a great source of Cu, K, P, Fe and Zn, since a daily consumption of 30 g provides an intake of approximately In terms of elements with potential risk to human health, Ni, Pb, Cd and As in Macedonian Goji berry had similar concentrations to Goji berry marketed in Spain [4] and Poland [9] and Hg was lower than in Italian Goji [16].…”

“…Due to its special nutritional composition (free sugars, carotenoids, polyphenols, flavonoides, vitamins, fatty acids, minerals, proteins, etc.) with health benefits such as immunity enhancement, antioxidant, anti-aging and anti-tumor effects, Goji berry has been proposed as functional food and included in the category of "superfoods" [4,[7][8][9][10][11][12][13][14][15][16][17]. Other major aspects of the medicinal quality of Goji fruit are heart disease risk reduction, hypoglycaemic, hypolipidemic and neuroprotective effects, prevention of some eye diseases and male fertility facilitation [18][19][20].…”

“…Rapid increase in consumption in Europe is noticed at the beginning of the twenty-first century [11,22]. Goji berries are consumed fresh, dried, processed into juice [4,9,10,13,23], as ingredient in snack, yoghurt and cereal bar [24] or as capsules and concentrated extracts [4]. Goji organic extract is added as natural antioxidant in extra-virgin olive oil and soybean oil to improve the oxidative stability and sensory profile such as taste, color or turbidity [24][25][26][27].…”

“…In Asia Goji is cultivated mostly in China, Taiwan and Japan, while in Europe most frequently in Southeastern countries. There is growing interest in Goji cultivation in Greece [10,15], Italy [8,13,16], Romania [12] and Bulgaria [28]. In recent years, Goji cultivation expanded to other European countries, such as Switzerland [11], Spain [4] and Poland [9].…”

BACKGROUND: Lycium barbarum L. has received considerable attention due to nutritional value of berries and its cultivation in Europe has attracted growing interest. OBJECTIVE: The aim of the study was characterization of Lycium barbarum L. berry cultivated in North Macedonia in terms of nutritional and functional properties and comparison with Lycium chinense M. variety. METHODS: Minerals, total proteins, sugars, antioxidant activity, fatty acids, carotenoids and polyphenols were determined and lipid indices were evaluated. Principal Component Analysis was used to describe variability of composition, while heat map to recognize the parameters significantly different for varieties. RESULTS: Lycium barbarum L. cultivated in North Macedonia represents a rich source of K, Cu, Mn, P, Zn, Mg, Fe and antioxidant compounds. Polyunsaturated fatty acids (mainly linolenic acid) were dominant in oil resulting in very low atherogenic and thrombogenic indices. A variability of 35.1% was ascribed to minerals, carbohydrates and proteins, 22.3% to ω-6 fatty acids and lipid indices of oil, 19.4% to nutrients with antioxidant activity and 13.4% to ω-3 fatty acids (n-3 and n-3/n-6 ratio). CONCLUSIONS: Chemometric analysis highlighted significant differences in terms of inorganic nutrients, antioxidant capacity, proteins, sugar profile and lipid indices in Lycium barbarum L. compared to Lycium chinense M.

BACKGROUNDIn goji berries (Lycium barbarum L.), the cell wall properties and ripening environment affect fruit quality and their economic benefits. However, the mechanism underlying the cell wall remains to be fully elucidated.RESULTSThe results showed that total sugar content was higher in Qinghai berries (13.87%, P < 0.01), whereas cellulose content peaked in Zhongning berries (28%, P < 0.05). Arabinose, galactose, and galacturonic acid were the principal components of the cell wall polysaccharides in goji berries. Among them, the content of galactose in Zhongning was significantly the highest (P < 0.05). Interestingly, we found that highly expressed β‐glucosidase and lowly expressed endoglucanase led to cellulose accumulation by RNA‐sequencing analysis. The expression analysis results suggested that pectate lyase and pectinesterase enzymes could be major factors related to higher galactose and galacturonic acid contents in Zhongning compared to in Qinghai and Gansu. The starch and sucrose metabolism pathway, pentose and glucuronate interconversions pathway, and galactose metabolism pathway played a significant role in cell wall polysaccharide synthesis and metabolism.CONCLUSIONIn the present study, we aimed to provide some insights into the cell wall on polysaccharide composition, structural features, and gene analysis in goji berries from Zhongning, Qinghai, and Gansu in China. These results might help to clarify the molecular function of the major genes in the cell wall polysaccharides of goji berries and provide a solid foundation for further study. © 2023 Society of Chemical Industry.
