β-Sitosterol Isolated from Theobroma Cocoa Induces the Expression Of Mkp-1 and Il-10 In Trigeminal Neurons
… The active compound was identified as β-sitosterol based on NMR and HPLC/MS/MS data. The anti-inflammatory mediators MKP-1 and IL-10 were up-regulated in trigeminal neurons in a concentration-dependent manner by β-sitosterol. A somewhat surprising finding from my study was that the active …

An investigation of genetic factors impacting sterol profiles in Australian olive oils
… a bifurcation that leads to the formation of β-sitosterol or campesterol, with the flux controlled by the activity of two enzymes, SAM-24-methylene-lophenol-C-24-methyltransferase2 (SMT2) and C-4α-sterol-methyl-oxidase2 (SMO2). Thus, it is conceivable that the relative activity/expression of …

Effect of phytosterol enrichment on the crystallisation, physiochemical, and interfacial behaviour of bulk and emulsified milk fat triacylglycerol matrices
Phytosterols possess the ability to significantly lower levels of low-density lipoprotein (LDL) cholesterol in the blood, but their bioaccessibility is dependent upon the solubility of the phytosterol in the consumable food or pharmaceutical product. Phytosterols are one of the most commonly used …
