人参皂甙 Rh1性质、用途与生产工艺
人参皂苷Rh1来源为五加科植物人参Panax ginseng C. A. Mey.的干燥根,是一种白色粉末状物质，溶解性:易溶于水、甲醇、乙醇，不溶于乙/醚、苯。
20(S)-Ginsenoside Rh1 (Prosapogenin A2, Sanchinoside B2, Sanchinoside Rh1)是从红参中提取的主要生物活性化合物之一，在世界范围内，红参已越来越多地用于增强认知和身体健康。它具有抗发炎、抗氧化、免疫调节作用和对神经系统有积极作用的有效特性。20(S)-Ginsenoside Rh1 可抑制 PPAR-γ、TNF-α、IL-6 和 IL-1β 的表达。

The effect of Ginsenoside Rh1 is examined on adipogenesis in 3T3-L1 cells. Ginsenoside Rh1 potently inhibits the adipogenesis, as assessed by Oil-red O staining and lipid contents in 3T3-L1 adipocytes. Ginsenoside Rh1, at concentrations of 50 μM and 100 μM, inhibit the adipogenesis by 50% and 63%, respectively.The expression levels of adipocytespecific genes such as PPAR-γ, C/EBP-α, FAS, aFABP and some genes are examined during early phase of differentiation such as Pref-1, C/EBP-δ and Glucocorticoid receptor (GR). After the treatment with Ginsenoside Rh1 in 3T3-L1 cells, mRNA is extracted on 18 h and 24 h for Pref-1, C/EBP-δ and GR and day 8 for PPAR-γ, C/EBP-α, FAS, aFABP. Then, the expression profiles of adipocyte-specific genes are investigated by RT-PCR. PPAR-γ, C/EBP-α, FAS, and aFABP expressions are significantly increased in DMI-stimulated differentiated adipocyte compared to those of non-stimulated adipocyte cells. However, treatment with DMI in the presence of Ginsenoside Rh1 significantly suppresses the expression levels of PPAR-γ, C/EBP-α, FAS, and aFABP in a dose- dependent manner, whereas the expression levels of Pref-1, C/EBP-δ and GR are not affected.
When high-fat diet (HFD) fed mice for 8 weeks, body and epididymal fat weight gains are significantly increased compared to those of low-fat diet (LFD)-fed mice. However, when Ginsenoside Rh1 is treated in HFD-fed mice, body and epididymal fat weight gains are significantly decrease compared with those of the HFD-fed mice. TG, glucose, insulin, total cholesterol, and HDL levels in the blood are significantly increased in HFD-fed mice group compared to LFD-fed mice group. Treatment with Ginsenoside Rh1 in HFD-fed mice significantly lowers TG level alone.
