“…In the binary variant correlation analysis, despite there being no correlation between ASG content and ASG recovery (or SG), PG purity was found positively correlated with phospholipid recovery (ASG recovery or SG content), strongly positive with ASG content but significantly negative with PG yield; while PG yield was strongly negatively correlated with phospholipid recovery, and positive with SG content, providing new insights into judgement of evaluating indicator in corresponding loading plots. Different from variant correlation analysis, the corresponding loading plot in PCA gave us a visual plot for qualitative evaluation of all referred indicators in PG extraction, which showed impact sequence of all mentioned indicators as follows (Fig. ): PG purity ≥ ASG content in PG extract ≥ total silica‐gel adsorption amount ≥ ASG recovery ≥ phospholipid recovery ≥ PG recovery ≥ SG recovery ≥ SG content in PG extract.…”

BACKGROUND: Soybean lecithin powders are good sources of phytosterol glucosides (PGs) containing acyl-sterylglycosides (ASGs) and sterylglucosides (SGs), but PG extraction from soybean lecithin powder is difficult due to the solubilizing property of phospolipids. To comprehensively utilize soybean lecithin resources, an evaluation system construction and factor impact analysis of PG extraction by silica-gel adsorption was investigated in this article. RESULTS:With high-performance liquid chromatography (HPLC) as the main experimental analysis method, software such as SIMICA and SPSS were applied to construct an evaluation system of PG extraction. Different from scores plot in SIMICA for distinguishing samples in chloroform from others, the loading plot and binary variant correlation analysis of all indicators in PG extraction were brought to confirm four evaluation indicators containing PG purity, ASG recovery, SG recovery and phospholipid recovery. In the factor impact analysis, four times elution from silica-gel sediment was enough to achieve a PG product with least reagent waste, while SPW in petroleum ether at 50 mg mL −1 with 1:3 silica-gel dosage (lecithin/silica-gel, w/w) was then determined as the optimum of single factors. CONCLUSION: All studies in this article were of great significance, as they laid foundations for research of PG extraction procedure, as well as PG industrial production, facilitating the comprehensive utilization of lecithin resources.

“…SG was first isolated from olives more than a century ago [1] and this compound was later identified as sitosteryl D-glucoside [2,3]. An acylated form of SG, phytosteryl 6 0 -O-acyl-glucoside, was then isolated from soybeans and potatoes [4].…”

Steryl glycosides (SGs) are sterols glycosylated at their 3β-hydroxy group. They are widely distributed in plants, algae, and fungi, but are relatively rare in bacteria and animals. Glycosylation of sterols, resulting in important components of the cell membrane SGs, alters their biophysical properties and confers resistance against stress by freezing or heat shock to cells. Besides, many biological functions in animals have been suggested from the observations of SG administration. Recently, cholesteryl glucosides synthesized via the transglycosidation by glucocerebrosidases (GBAs) were found in the central nervous system of animals. Identification of patients with congenital mutations in GBA genes or availability of respective animal models will enable investigation of the function of such endogenously synthesized cholesteryl glycosides by genetic approaches. In addition, mechanisms of the host immune responses against pathogenic bacterial SGs have partially been resolved. This review is focused on the biological functions of SGs in mammals taking into consideration their therapeutic applications in the future.
