“…But the polyunsaturated acids are formed essentially by linolic and linolenic acid. This abundance of unsaturated fatty acids (68.5% to 72.4%) was also noticed in jujube fruits and 26.4 to 30.2% for saturated fatty acid (San et al, 2010).This composition can give preventive action against cardiovascular disease by lowering levels of cholesterol (Watkins et al, 2003;Tapiero et al, 2002;Hachicha et al, 2006). 42.82 ± 0.28b 50.68 ± 0.28a 32.37 ± 6.33c Linoleic (oméga-6) C 18 : 2n6 10.88 ± 0.89c 18.13 ± 0.51a 13.29 ± 0.04b 13.6 ± 1.76b Arachidic C20 : 0 1.59 ± 0.55a 1.06 ± 0.05b 0.73 ± 0.02b 1.64 ± 0.06a Linolenic (oméga-3) C18: 3 n3a 1.63 ± 0.07a 1.33 ± 0.05b 1.76 ± 0.04a 0.86 ± 0.29c Gadoleic C20 :1c 1.3 ± 0.15a 1.08 ± 0.08a 0.77 ± 0.04c 0.9 ± 0.13bc Behenic C22 : 0 0.56 ± 0.92a 0.85 ± 0.05a 0.58 ± 0.01a 0.67 ± 0.67a Omega-6/Omega-3 6.…”

San et al (2010) have qualified Ziziphus oil as a mixture of linoleic, oleic, palmitic and palmitoliec acid. On the other hand, the results showed an assessment of saturated, monounsaturated and polyunsaturated fatty acids in the pulp of Ziziphus values 29.62% to 37.3%; 48.17% to 59.89% and 12.51% to 15.05% the most important saturated fatty acids were palmitic, stearic, behenic and arachidic acid.…”

Thirteen fatty acids were identified from the pulps of four Tunisian Ziziphus jujuba ecotypes (Sfax, Choutrana, Mahres and Mahdia), using capillary gaseous chromatography method. These oils presented 8.31% to 12.35% of dry weights. Compared to the other ecotypes, Mahres and Choutrana were the richest of the oleic acid. The palmitic acid was the most important compound of the Sfax ecotype. Unsaturated fatty acids ranged from 62.63% to 72.40% of the total fatty acids of each ecotype. So a ratio of the unsaturated/saturated (U/S) varied from 1.68 to 2.37. The β-sitosterol and the Stigmasterol were identified as major sterols. The β-sitosterol was the prominent component in the all ecotypes and the highest level (10.65 mg/100g) was noted in Choutrana ecotype. Stigmasterol was more abundant in Sfax (16.12 mg/100g) and Choutrana (4.67 mg/100g) ecotypes. The campesterol sterol was identified only in Sfax and Choutrana ecotypes being more important (2.4 mg/100g) in Choutrana pulps.

“…Among these seven quercetin derivatives, the peak of C11, identified as rutin, was the highest in the LC and MS spectrum. In jujube fruit, rutin has been reported as the most abundant flavonoi, [23,24] and is a known bitter chemical. So, rutin might be considered as a bitterness marker in jujube fruit.…”

Bitterness in dried jujube fruit can adversely influence its palatability and consumer acceptability. In the present investigation, sensory-guided fractionation with techniques of liquid-liquid extraction, macroporous resin separation, and LC-MS/QTof was applied to identify the bitter compounds in dried jujube fruit (Z. jujuba cv. junzao). The results showed that bitter substances can be successfully extracted from dried jujube fruit using ethanol followed by n-butanol solution. The extract could then be further separated into five fractions by utilizing the macroporous resin separation technique. From this, three bitter fractions were obtained where 35 compounds, including 7 nitrogen compounds, 14 flavonoids, 12 saponins, and 2 fatty acid oxides，were tentatively identified. Based on the structures of these compounds, bitterness generation is likely to result from endogenous phytochemicals of jujube fruit and Maillard reactions during drying processing and also storage.

“…is a perennial tree in the Rhamnaceae family and has a wide natural distribution in tropical and subtropical parts of the world [21]. The jujube fruits are edible and have been used in Korean folk medicine as San-Jo-In and in Chinese folk medicine as Suan-Zao-Ren or SuanZao-He with high sugar content and high levels of vitamin A, B and C complexes, phosphorus and calcium [24]. This plant possesses various pharmacological properties such as liver problems, insomnia and anxiety [13,28].…”

Essential oils have been used to treat psychophysiological disorders, but their effects on human electroencephalographic (EEG) activity have not been thoroughly investigated. We evaluated the effects of essential oil of Zizyphus jujuba seeds, a Korean folk medicine known as San-Jo-In, on human EEG activity. For this purpose, essential oil was extracted from San-Jo-In by the supercritical carbon dioxide extraction method. The effect of its inhalation on EEG activity was evaluated by measuring the EEG power spectrum (25 indices) in 20 healthy participants. The results of the EEG power spectrum indicated that the values of the theta wave decreased significantly (p<0.05) in the left (from 17.277 to 13.854 µV) and right parietal (from 15.324 to 13.020 µV) regions compared to the other regions. During the inhalation of San-Jo-In oil, the EEG spectrum values of fast alpha, relative gamma, and spectral edge frequency increased 50% compared to those before inhalation. The values of the fast alpha wave increased significantly (p<0.05) in the left prefrontal (from 0.063 to 0.085 µV), right prefrontal (from 0.064 to 0.085 µV), and left frontal (from 0.073 to 0.100 µV) regions following inhalation of the San-Jo-In essential oil. The changes in the EEG activities following inhalation of San-Jo-In suggest that the oil can improve psychological well-being by increasing attention and relaxation.
