Abstract:
Objective:To study the anti-inflammatory activity of total alkaloids from Solanum lyratum.Methods:Human umbili-cal vein endothelial cells ( HUVECs) were cultured and induced by H 2 O2 (200 μmol· L-1 ) , and RAW 264.7 cells were cultured and induced by lipopolysaccharide ( LPS ) .The two inflammatory cell models were randomly divided into the normal group , model group, positive control group, and total alkaloids group respectively at low , medium and high dose.After the treatment, the cells were continued to be cultured , and CCK-8 method was applied to observe the cell survival rate .SD rats were randomly divided into the nor-mal group, model group, positive control group, total alkaloid group respectively at low, medium and high dose,and then the rats re-ceived subplantar injection of carrageenan in the paw .After the treatment , inflammation was analyzed by the swelling degree of acute ankle joint injury, and the contents of prostaglandin E2 (PGE2) and cyclooxygenase-2 (cox2-) were detected.Results:The effect of total alkaloids from Solanum lyratum at medium dose on H 2O 2-induced HUVECs and that of total alkaloids from Sola num lyratum at high dose on LPS-stimulated macrophages were similar to that of the positive control group without statistical significance (P>0.05), and the total alkaloids from Solanum lyratum at medium and high dose could significantly reduce the swelling degree of the acute ankle model in rats (P<0.01), and decrease the content of PGE2 in the toe exudate of rats and that of COX-2 in serum (P<0.01) with statistical significance when compared with that in the model group (P<0.01).Conclusion:The total alkaloids from Solanum lyra-tum have significant anti-inflammatory activity , and it is necessary to further study the efficacy and action mechanisms .
