Recent drought across the desert Southwest US may strongly affect the physiological functioning of evergreen desert species that maintain leaves through these dry periods. In July 2002 we compared the ecophysiological performance of the open-canopied, small-leaved creosotebush (Larrea tridentata) to the dense-canopied, more broad-leaved jojoba (Simmondsia chinensis) growing on a ridge-top, east...

Due to the rising interest in healthy products, super foods such as pomegranate have spread widely on international market recent years. Several postharvest treatments been applied order maintain quality and extend shelf life of arils. This study evaluated effect Arabic gum treatment well different edible coatings (Jojoba oil, Gelatin, Wheat Germ oil Rosemary oil) fruit parameters Wonderful dur...

Aliphatic alcohols of chain lengths of 24–34 carbons have been found to be beneficial in treating hypercholesterolemia. Approximately 40% of beeswax is long-chain esters which can be transesterified in supercritical carbon dioxide to give these alcohols and fatty acid methyl esters. The methanolysis reaction was catalyzed by an immobilized lipase from Candida antarctica in flowing supercritical...

Hyperglycemia occurs during diabetes and insulin resistance. It causes oxidative stress by increasing reactive oxygen species (ROS) levels, leading to cellular damage. Polyphenols play a central role in defense against oxidative stress. In our study, we investigated the antioxidant properties of simmondsin, a pure molecule present in jojoba seeds, and of the aqueous extract of jojoba seeds on f...

supercritical carbon dioxide (sc-co2) was used as solvent to synthesize oleyl oleate as an analog of jojoba oil from oleic acid and oleyl alcohol with high conversion (100%) of the acid into ester in a short time of 100 min. utilizing a low cost solid catalyst, p-toluenesulfonic acid monohydrate (ptsa), the esterification reaction was performed, without any prior preparation step, in a flow mod...

Jojoba seed meal (Simmondsia chinensis) contains approximately 15% glucosides identified as simmondsin, 5-demethyl simmondsin, didemethyl simmondsin, along with simmondsin 2%-ferulate, 4-demethyl simmondsin 2%-ferulate, and 5-demethyl simmondsin ferulate. The new simmondsin derivative was isolated from jojoba meal by a combination of column chromatography and preparative HPLC and identified by ...
