摘要
比较不同灵芝三萜单体对PC12细胞保护和自噬诱导活性的差异。结果表明,灵芝酸A、B、C、C2、DM、K对H2O2诱导的细胞损伤最大保护率分别为32.83%、12.63%、53.03%、30.30%、2.53%和25.25%;对Aβ25-35诱导的细胞损伤最大保护率分别为6.74%、29.02%、23.81%、25.07%、10.15%和5.12%;自噬诱导最大阳性率分别达到22.33%、32.67%、35.50%、28.33%、11.83%和29.50%。不同灵芝三萜单体的活性也有明显的差异,且各单体在不同活性方面均未表现出一致的强弱关系。
The different effects of C,.anoderrna triperpenoids on cytoprotection and autophag＇y induction in PC12 cells were studied. The results showed that the maximum protection rates of Ganoderie acid A, B, C, C2, DM, K on H2O2 induced toxicity were 32. 83%, 12. 63%, 53.03%, 30. 30%, 2. 53% and 25.25%, respectively. The maximum protection rates on Aβ25-35 induced toxicity were 6. 74%, 29. 02%, 23.81%, 25.07%, 10. 15% and 5.12%, respectively. The maximum autophagy induction rates were 22. 33%, 32. 67%, 35.50%, 281 33%, 11.83% and 29. 50%, respectively. There was a very significant difference in C, anoderma triperpenoids on eytoprotection and autophagy induction, and the rankings of a certain triperpenoid were varied in different activity tests.
