“…In the same respect, ethanol extract of Nabaq pulp contain the highest flavonoids content (180.01 mg CE/ g extract) compared to seeds. These results are in agreement with El Maaiden et al (2019) who found that extraction with water gave the highest phenolics (39.74 mg gallic acid equivalent / g of dry weight of the seeds of Nabaq while extraction with methanol gave the highest flavonoids content ( 14.58 mg quercetin equivalent/ g of dry weight ) in the Z. lotus seeds . Mean ± SD of triplicate analysis.…”

“…The Nabaq seeds are a source of sulphur-rich amino acids and linoleic acid which showed high activity against Escherichia coli and Bacillus subtilis (Nazif, 2002). The Nabaq pulp has sweet taste as well as natural nutritive source and can be consumed either fresh or dehydrate in the manufacture of candy (Adekunle andAdenike, 2012 andEl Maaiden et al, 2019). It showed biological activities such as antioxidants, active against bacterial and fungal pathogens antidiarrheal, antitumor and immunostimulatory activities (Adzu et al, 2003, andAbalaka et al, 2011).…”

Nabaq (Zizyphus spina-christi) has various functional and technology properties, which can be used as a natural source of therapeutic functional compounds. The physicochemical properties, bioactive compounds, and antioxidant activities, of the pulp and seeds of Nabaq fruit from Egypt and its application in some functional products were investigated. The results revealed that the dehydrate seeds contain high contents of crude protein (9.64%), and ether crude extract (13.95%), while, dehydrate pulp had high content of total carbohydrates (90.94%). The carbohydrate fractions were found to be ranged from 4.05 to 16.61% starch, 28.87 to 43.52% reducing sugars, 9.72 to 27.19%, sucrose, and 4.5 to 18.45% glucose in seeds and pulp, respectively. The Nakaq pulp was a good source of dietary fiber, vitamin C, and minerals especially Zn which where realized approximately 106.5% of daily requirements. The pulp was also characterized by higher total phenolics (46.62 mg/g) and flavonoids (165.68 mg/100g) than the seed which had IC50 values 13.88 mg/ ml for 36.02% inhibition of DPPH free radicals. The evaluation of sensorial attributes of biscuits products prepared with powdered Nabaq seeds as replacement of wheat flour (20%) and fat (25%) showed the highest sensory overall acceptability scores. Cookies products prepared with powdered Nabaq pulp as a substitution of 10% wheat flour showed nearly closed acceptability to the control while cakes containing 20% pulp gave the highest score of sweetness, flavour, overall acceptability. Also, pudding containing 50% Nabaq pulp had the highest overall acceptability in all sensory attributes.

“…The isolation of flavonoids, or compounds insoluble in oil, is relatively simple, since the oil can be effectively extracted with petroleum ether. In this way, flavonoids have been recovered from seeds of Gloriosa superba [ 17 ], Paullinia cupana [ 18 ], Ziziphus lotus [ 19 ], and Salvia hispanica L. [ 20 ], among others.…”

The flavonoids are compounds synthesized by plants, and they have properties such as antioxidant, anticancer, anti-inflammatory, and antibacterial, among others. One of the most important bioactive properties of flavonoids is their antioxidant effect. Synthetic antioxidants have side toxic effects whilst natural antioxidants, such as flavonoids from natural sources, have relatively low toxicity. Therefore, it is important to incorporate flavonoids derived from natural sources in several products such as foods, cosmetics, and drugs. For this reason, there is currently a need to extract flavonoids from plant resources. In this review are described the most important parameters involved in the extraction of flavonoids by unconventional methods such as ultrasound, pressurized liquid extraction, mechanochemical, high hydrostatic pressure, supercritical fluid, negative pressure cavitation, intensification of vaporization by decompression to the vacuum, microwave, infrared, pulsed electric field, high-voltage electrical discharges, and enzyme-assisted extraction. There are no unified operation conditions to achieve high yields and purity. Notwithstanding, progress has been achieved in the development of more advanced and environmentally friendly methods of extraction. Although in literature are found important advances, a complete understanding of the extraction process in each of the unconventional techniques is needed to determine the thermodynamic and kinetic mechanisms that govern each of the techniques.

“…Moreover, Z. lotus aqueous and organic extracts are characterized by the presence of flavonoids and tannins [ 11 ]. Particularly, cyclopeptide alkaloids, termed lotusines, and dammarane saponins have been isolated from this shrub, along with polyunsaturated fatty acids (oleic acid and linoleic acid), carbohydrates, and fibers [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

“…A comparative study of two Zizyphus species, namely spina christi and lotus from Morocco, highlighted the presence of essential nutrients and phytochemical compounds in the fruits, pulps, seeds, and almonds. Flavonoid and anthocyanin contents were found to be highest in methanolic extract of the seeds and almonds of Z. lotus [ 16 ]. An earlier study reported the concentrations of different vitamins (vitamin A, C, and E) and fatty acids in root, stem, leaves, fruit pulp, and seed of Z. lotus L. The results achieved showed higher vitamin A and C contents in the fruit pulp and a richer source of linoleic acid (18:2n−6) than that in other parts of the plant [ 20 ].…”

Physico-Chemical and Phytochemical Characterization of Moroccan Wild Jujube “Zizyphus lotus (L.)” Fruit Crude Extract and Fractions

et al. 2020

Wild jujube “Ziziphus lotus (L.) Desf.” belongs to the Rhamnaceae family and is a traditionally herbaceous medicinal plant. It is very common in arid and semi-arid regions and is currently used for its antidiabetic, sedative, analgesic, anti-inflammatory and hypoglycemic activities. The aim of the present work was to characterize the physico-chemical properties and the phytochemical profile of wild jujube sample collected from the Guercif region, in order to determine the polyphenolic compounds and the antioxidant ability Analyses were carried out directly after the harvest for the determination of pH, refractive index, total soluble solid (°Brix), dry matter, sugar/acidity, total sugars, reducing sugars, as well as lipid and protein content. Results showed that the investigated fruit is acidic (pH 4.9 ± 0.23) and rich in sugars (80.2 g/100 g ± 3.81). The GC-MS analysis of the fruit revealed a number of volatile compounds, as many as 97, belonging to different chemical classes. The HPLC-DAD-ESI/MS analysis showed the presence of a total of 20 polyphenolic compounds in both EtOAc and MeOH-water extracts. Among them, p-Hydroxybenzoic acid was the most abundant in the EtOAc extract (185.68 µg/100 mg ± 0.5) whereas Quercetin 3-O-rhamnoside-7-O-glucoside was found in higher amounts in the MeOH-water extract (25.40 µg/100 mg ± 0.5). These components have medical interest, notably for human nutrition, as well as health benefits and therapeutic effects. Therefore, Moroccan jujube “Zizyphus lotus (L.)” fruit may have potential industrial applications for food formulations.
