Objective:
To observe the anti-tumor activity of the ethanol extracts of Solanun lyratum in vitro and in vivo.
Method:
In vitro, the inhibitory effects of ethanol extracts of S. lyratum on proliferation of human hepatoma BEL-7402 cell and gastric carcinoma SGC-7901 cell were measured by MTT colorimetric assay. The mouse tumor model was used to investigate the effects of ethanol extracts on tumor growth.
Result:
The studies demonstrated that ethanol extracts of S. lyratum inhibited proliferation of BEL-7402 cells and SGC-7901 cells, and the IC50 values on them were (287.40 +/- 5.84) micron x mL(-1) and (176.14 +/- 5.18) microg x mL(-1), respectively. The tumor inhibitory rate of high doses of ethanol extracts on S180 sarcoma-transplanted mice and H22 hepatic cancer were (41.15 +/- 4.54) % and (45.00 +/- 7.37) %, respectively. When the dose of ethanol extracts varied from low to high, it was able to inhibit the growth of S180 sarcoma-transplanted mice and H22 hepatic cancer in a dose-dependent manner.
Conclusion:
In tumor inhibitory test, it was shown that the ethanol extracts of S. lyratum may possess significantly inhibitory effect in vitro and in vivo. No acute toxic effect was found in our experiment.
