Application

在对植物来源的油样品进行GC 和HPLC 分析时，菜油甾醇被用作标准品。

Biochem/physiol Actions

植物甾醇。可降低膳食胆固醇的吸收。
菜油甾醇是一种植物甾醇，主要存在于坚果、水果、豆类和种子中。虽然它是胆固醇的类似物，但它在人体中的吸收很差，并且能够竞争性抑制胆固醇的吸收。菜油甾醇降低了参与肝细胞和肠细胞中胆固醇代谢的基因的转录，并且对心血管疾病的治疗具有积极影响。

Preparation Note

菜油甾醇以20mg/ml浓度溶于氯仿，可得到透明、无色至淡黄色的溶液。

Analysis Note

通过HPLC和GC分析得到二氢菜子甾醇（24β-甲基-5-胆甾烯-3β-醇；24[S]-麦角甾-5-烯-3β-醇）的含量约为98%，但 13C-NMR显示含量约为35％。

Effective statin therapy is associated with a marked reduction of cardiovascular events. However, the explanation for full benefits obtained for LDL cholesterol targets by combined lipid-lowering therapy is controversial. Our study compared the effects of two equally effective lipid-lowering strategies

The impact of increased serum concentrations of plant sterols on cardiovascular risk is unclear. We conducted a systematic review and meta-analysis aimed to investigate whether there is an association between serum concentrations of two common plant sterols (sitosterol, campesterol) and

Plant sterols such as sitosterol and campesterol are frequently administered as cholesterol-lowering supplements in food. Recently, it has been shown in mice that, in contrast to the structurally related cholesterol, circulating plant sterols can enter the brain. We questioned whether
