人参皂苷Rb_1对脂质体二棕榈酰磷脂酰胆碱相变温度的影响

Influence of Ginsenoside- Rb_1 on the Phase Conversion Temperature of the Liposome DPPC

用差示扫描量热技术（ＤＳＣ）和核磁共振技术（ＮＭＲ）研究了脂质体相变温度与人参皂苷Ｒｂ＿１的关系。结果表明，Ｒｂ＿１使二棕榈酰磷脂酰胆碱相变温度降低、流动性增加，改善了细胞膜的功能。

We studied the relationship between Ginsenoside- Rb_1, and phase conversion temperature ofthe liposome,using the technique of DSC and NMR. The Ginsenoside-Rb_1 can reduce phase conver- sion temperature of the liposome DPPC,increase it's fludity and improve the function of the cell’smembrane.
