A hitherto unreported esterified form of steryl glucoside has been isolated from potato tuber lipids and soybean phosphatides. It is composed of sterol, glucose, and fatty acid in the molar ratio 1 : 1 : 1. Four components of the sterol moiety have been detected ; they include &sitosterol and stigmasterol (identified by gas-liquid chromatography). Fatty acids are palmitic, stearic, oleic, linol...

Olive oil is an important component of Mediterranean diet widely, consumed thanks to its numerous health-healing properties. Its quality dependent upon a set factors (genotypic, environmental, agronomic practices, ripening, etc). These are well documented, but little known about the impact extraction technology on ‘Moroccan Picholine’ olive quality. In this paper, physicochemical traits (cv Pic...

The chemical composition and CIELAB color parameters of oil from three aguaje morphotypes ( Mauritia flexuosa L.f.) extracted by supercritical carbon dioxide was investigated. By chromatography (HPLC GC), spectrometry (UV/vis), digital image colorimetry (digital camera), carotenoids, tocopherols, tocotrienols, fatty acids, total polyphenols, space were analyzed. These findings showed that the o...

OBJECTIVE To examine the anti-bacterial activity of leaf extracts of Morus alba L. (Moraceae) and Piper betel L. (Piperaceae), and seed extracts of Bombax ceiba L. (Borabacaceae). METHODS We have partially purified plant extracts by solvent extraction method, and evaluated the effect of individual fractions on bacterial growth using Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aerug...

We prepared a crude gel material from Aloe vera succulent leaf tissues. The ethanolic extract of lyophilized A. vera gel was used for the GC-MS analysis. Hexadecanoic acid (22.22%) was identified as major compound. Sitosterol and stigmasterol were found to be 2.89% and 2.1% in the extract. HPLC analysis was carried out to confirm the presence of stigmasterol. The concentration of sterol extract...

Ferulago species have been utilized since ancient times as digestive, sedative, aphrodisiac, along with in salads or as a spice due to their special odors. The study reports isolation and characterization of bioactive compounds of Ferulago pachyloba (F. pachyloba), Ferulago trachycarpa (F. trachycarpa), Ferulago bracteata (F. bracteata), and Feru...

The ABC transporters ABCG5 and ABCG8 limit absorption and promote excretion of dietary plant sterols. It is not known why plant sterols are so assiduously excluded from the body. Here we show that accumulation of plant sterols in mice lacking ABCG5 and ABCG8 (G5G8-/- mice) profoundly perturbs cholesterol homeostasis in the adrenal gland. The adrenal glands of the G5G8-/- mice were grossly abnor...

Vitamin D3 (cholecalciferol) and stigmasterol have been shown to stimulate Ca2+ uptake and to induce calmodulin synthesis in cultured French-bean (Phaseolus vulgaris) roots. In addition, the appearance of calmodulin in the cultures in response to vitamin D3 could be prevented by RNA-synthesis inhibitors. To investigate the possibility that the sterols affect root DNA transcription through a rec...
