[Study on anticancer effect in vivo of active fraction from Nervilia fordii]

To determine the active fraction with anticancer effect in vivo from Nervilia fordii.

The effective petroleum ether extract and ethyl acetate extract parts preliminary were selected in vitro, then anticancer experiments in vivo were done by S180-mice and H22-mice models.

Petroleum ether extract and ethyl acetate extract parts both had obvious anticancer effects to S180-mice and H22-mice, and could prolong H22-mice life. Meanwhile, they could improve the immunoloregulation of mice.

It is the first time that the petroleum ether extract and ethyl acetate extract of Nervilia foadii are proved to be the effective anticancer fractions in vivo. On this basis, the further studies are needed on active principles or principle group with anticancer effect and the characteristics of this effect in Nervilia foadii.
