“…[69] Similar growth retardation was observed in male rats fed defatted jojoba meal which, therefore, concluded that the growth retardation seen with defatted jojoba meal was due to its simmondsin activity through its role in food intake reduction. [70] The results of this study also revealed that treatment with jojoba seed extract at both low and high doses did not affect the activity of ALS, AST, triglycerides level, or serum cytokines suggesting that the treatment did not cause liver toxicity. However, jojoba seed extract induced a slight increase in NO.…”

“…However, jojoba seed extract induced a slight increase in NO. According to Kampf et al, [70] jojoba contains a natural antioxidant postulated to be an allylic derivative of hydroxytoluene. Van Boven et al [71] isolated eight glucoside compounds from jojoba seeds and Bouali et al [40] reported that jojoba is rich in phytic acid and omega-3 fatty acid.…”

International audienceAim: This study aimed to determine the composition of ethanol extract of jojoba seeds, and to evaluate its hepatoprotective effects in rats fed fumonisin B1 (FB1)-contaminated diet.Methods: Jojoba seeds were extracted in 95% ethanol, and the chemical composition was determined. Male rats were divided into six groups and treated for 8 weeks as follows: (1) Untreated control; (2) FB1-contaminated diet (80 mg/kg diet); (3) low dose (0.5 mg/kg b.w.) jojoba extract; (4) high dose (1.0 mg/kg b.w.) jojoba extract; (5) low dose jojoba extract plus FB1; and (6) high dose jojoba extract plus FB1. Blood and liver samples were collected for different biochemical analyses and histological examinations.Results: The results indicated that the ethanolic extract of jojoba is rich in protein, phenolic compounds, phytic acid, and considerable amounts of simmondsin. Animals fed FB1-contaminated diet showed severe biochemical and histological changes typical to those reported in literature. Treatment with jojoba seed extract alone at the two tested doses did not induce significant alterations in all parameters tested. Combined treatment of jojoba seed extract with FB1 eliminated hepatotoxicity induced by FB1, especially at low dose of jojoba seed extract.Conclusion: The authors concluded that jojoba seed extract can be incorporated in FB1-contaminated feed to eliminate FB1-induced hepatotoxicity

“…The cosmetics industry is currently the largest market for jojoba oil, and consumer demand continues to rise for natural skin care products [e.g., moisturizers, makeup, shampoos, and conditioners (15)]. In addition to its importance to the cosmetics industry, jojoba oils are also widely regarded for their excellent mechanical lubricity properties including stability at high temperatures and pressures (16), antifoaming, antiwear, and antirust properties (17,18), and oxidative stability (19). Because of the high oil content of its seeds, economic value, and the capacity of the plants to grow in hot, arid climates (35° to 48°C), jojoba has garnered considerable attention for domestication in some of the world's most unfavorable environments.…”

Seeds of the desert shrub, jojoba (Simmondsia chinensis), are an abundant, renewable source of liquid wax esters, which are valued additives in cosmetic products and industrial lubricants. Jojoba is relegated to its own taxonomic family, and there is little genetic information available to elucidate its phylogeny. Here, we report the high-quality, 887-Mb genome of jojoba assembled into 26 chromosomes with 23,490 protein-coding genes. The jojoba genome has only the whole-genome triplication (γ) shared among eudicots and no recent duplications. These genomic resources coupled with extensive transcriptome, proteome, and lipidome data helped to define heterogeneous pathways and machinery for lipid synthesis and storage, provided missing evolutionary history information for this taxonomically segregated dioecious plant species, and will support efforts to improve the agronomic properties of jojoba.

“…Treatment with Jojoba oil to rats fed AFcontaminated diet improved food consumption and body weight gain which may be due to the withdrawal of the effect of simmondsin (Cokelaere et al, 2000). Similar growth retardation was observed in male rats fed defatted Jojoba meal which, therefore, concluded that the growth retardation seen with defatted Jojoba meal was due to its simmondsin activity through its role in food intake reduction (Kampf et al, 1986).…”

Aim: This study aimed to evaluate the hepatoprotective effect of Jojoba oil(J.O.) and Nigella sativa seeds(N.S.) in rats fed diet contaminated with aflatoxin(AF).Methods: Forty mature male rats were divided into eight groups and treated for 30 days as follows: (1) Untreated control; (2) Jojoba oil 1.25% (low concentration) ; (3) Jojoba oil 2.5% (high concentration) ; ( 4) Aflatoxin (AF)-contaminated diet (30ug/kg diet); (5) low dose Jojoba oil plus AF; (6) high dose Jojoba oil plus AF; (7) Nigella sativa seeds at 2.5% and (8) Nigella sativa seeds plus AF. Blood samples were collected for biochemical analyses and livers were taken DNA measurement. Results:The results indicated that Jojoba oil is rich in protein, phenolic compounds, phytic acid, and considerable amounts of simmondsin. Animals fed AFcontaminated diet showed severe biochemical changes and DNA damage. Feeding on ration mixed with Jojoba oil alone at the two tested concentrations or Nigella sativa seeds did not induce significant alterations in all tested parameters. Treatment with Jojoba oil to rats fed AF containing diet protected against hepatotoxicity and DNA damage induced by AF. Conclusion:It can be concluded that Jojoba oil and Nigella sativa seeds can be incorporated in AF-contaminated feed to protect against hepatotoxicity and DNA damage induced by AF.
