Objective:
To study the anti-endotoxin of different concentration baicalin.
Methods:
6.250 microg/mL, 3.125 microLg/mL, 1.562 microg/mL and 0.781 microg/mL baicalin solutions were mixed with I EU/mL endotoxin, respectively. The mixtures were put into water of (37+/-1) degrees C for 15 min, 30 min and 60 min. The degrading effects were determined by using limulus amebocyte lysate test (LAL test).
Results:
1) The degrading effect of 6.250 microg/mL, 3.125 microg/mL and 1.562 microg/mL baicalin solution on I EU/mL endotoxin was degraded completely in 15 min, 30 min and 60 min, respectively. 2)The degrading effect of 3.125 microg/mL, 1.562 microg/mL and 0.781 microg/mL baicalin solution on 1 EU/mL endotoxin after these mixtures had been incubated for 15 min. Endotoxin values were (0.155 5 +/- 0.002 8) EU/mL, (0.212 1+/-0.004 9) EU/mL, (0.355 9+/-0.013 9) EU/mL, respectively. These differences among them were statistically significant (P<0.01). 3) The degrading effect of 1.562 microg/mL and 0.781 microg/mL baicalin solution on 1 EU/mL endotoxin after these mixtures had been incubated for 30 min. Endotoxin values were (0.1640+/-0.0025) EU/mL and (0.2094+/-0.004 4) EU/mL, respectively. These differences between them were statistically significant (P<0.01).
Conclusion:
The action of anti-endotoxin of baicalin is dose-dependent and time-dependent. The results show that baicalin has the stronger anti-endotoxin effect.
