Esterified steryl glucosides are sterol derivatives that have been found in vegetables, vegetable oils, fruits, cereals, legumes, fungi, and algae. They have also been found as bioactive lipids in pre-germinated brown rice. The level of esterified steryl glucosides decreases in microsomal membranes from the pericarp of tomatoes stored at a low temperature (2°C) and increases in mature-green tomatoes when stored at 38°C. Esterified Steryl Glucosides is a mixture of β-sitosteryl glucoside, β-campesteryl glucoside, and β-stigmasteryl glucoside.

Comparative citrus fatty acid profiles of triglycerides, monogalactosyl diglycerides, steryl esters and Esterified Steryl Glucosides
Lipids 1971 Aug;6(8):554-61.PMID:27519513DOI:10.1007/BF02531135.
Vesicular lipids from six orange and two tangor varieties were extracted, purified and separated by chromatography into triglycerides, monogalactosyl diglycerides, steryl esters and Esterified Steryl Glucosides. Methyl esters of the fatty acids found in these four lipids were prepared and analyzed by gas liquid chromatography. Each of the eight citrus varieties gave a series of four profiles which could be distinguished from the others. The Temple tangor has four profiles all showing a large percentage of linolenic acid. In all varieties steryl esters and to a lesser extent Esterified Steryl Glucosides contain relatively large concentrations of 22∶0 to 26∶0 saturated acids. The profiles differ markedly from the patterns found for these four lipids in other higher plants studied.
On the glucoside analysis: simultaneous determination of free and Esterified Steryl Glucosides in olive oil. Detailed analysis of standards as compulsory first step
Food Chem 2013 Nov 15;141(2):1273-80.PMID:23790913DOI:10.1016/j.foodchem.2013.03.080.
This work covers two important gaps in the field of micronutrient databases: herein we describe a short and easy protocol that allows the analysis of both free and esterified steryl gulcosides in olive oil. By utilising accurate quantitative methods we achieve a better understanding of olive oil composition and health promoting properties. The procedure consists of isolating the fraction of interest through solid phase extraction, and using gas chromatography-flame ionisation detection for both identification and quantification of the derivatised species. Additionally, mass-spectrometry detection has been utilised for confirming the identity of the individual Esterified Steryl Glucosides in some cases. The method's limit of detection has been set at 0.37mg/kg for each free steryl glucoside and 0.20mg/kg for each esterified steryl glucoside, whereas the recoveries are around 96% and 77%, respectively. Finally, we provide a complete analysis of the commercial standard for Esterified Steryl Glucosides, since such information was not yet available.
Glycolipid composition of Hevea brasiliensis latex
Phytochemistry 2011 Oct;72(14-15):1902-13.PMID:21605880DOI:10.1016/j.phytochem.2011.04.023.
Glycolipids of fresh latex from three clones of Hevea brasiliensis were characterized and quantified by HPLC/ESI-MS. Their fatty acyl and sterol components were further confirmed by GC/MS after saponification. The four detected glycolipid classes were steryl glucosides (SG), Esterified Steryl Glucosides (ESG), monogalactosyl diacylglycerols (MGDG) and digalactosyl diacylglycerols (DGDG). Sterols in SG, ESG and total latex unsaponifiable were stigmasterol, β-sitosterol and Δ⁵-avenasterol. The latter was found instead of fucosterol formerly described. Galactolipids were mainly DGDG and had a fatty acid composition different from that of plant leaves as they contained less than 5% C18:3. Glycolipids, which represented 27-37% of total lipids, displayed important clonal variations in the proportions of the different fatty acids. ESG, MGDG and DGDG from clone PB235 differed notably by their higher content in furan fatty acid, which accounted for more than 40% of total fatty acids. Clonal variation was also observed in the relative proportions of glycolipid classes except MGDG (8%), with 43-51% DGDG, 30-34% SG and 7-19% ESG. When compared with other plant cell content, the unusual glycolipid composition of H. brasiliensis latex may be linked to the peculiar nature of this specialized cytoplasm expelled from laticiferous system, especially in terms of functional and structural properties.
Comparative study of phytosterol derivatives in monovarietal olive oils
J Agric Food Chem 2014 Jun 18;62(24):5669-74.PMID:24861171DOI:10.1021/jf501340q.
Plant sterols and their derivatives are minor compounds that have been extensively studied in vegetable oils, mainly in olive oil, where they are closely related with its identity. The objective of this work is to determine the content of free and Esterified Steryl Glucosides and their profiles in olive oil in relation to different geographical situation of olive orchards, cultivar, farming modality, and sampling time. The orchards under study were located in the outer ring of the submetropolitan area of Madrid (Spain), where olives from Cornicabra, Manzanilla Cacereña, Manzanilla Castellana, and Picual varieties were grown under traditional and organic modes, and harvested in four different samplings. Conclusions state that cultivar, farming mode, and light exposure do not have outstanding effects, whereas pedoclimate might affect the steryl glucoside presence in a substantial way. Further studies are being carried out presently in order to confirm such statement. Also glucoside derivative profiles are discussed, and reasons for differences with results in previous studies pointed out.
