應用

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。

生化/生理作用

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。

品質

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%。

準備報告

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。
