This study was conducted to employ an ovarian cancer Ovcar 10 three-dimensional model to assess the antiproliferation activity of the medicinal plant Devil's club, Oplopanax horridus, and its active compound, alone and in combination, with chemotherapeutic agents compared to Ovcar 10 two-dimensional
The root of Oplopanax elatus (Nakai) Nakai has a well-known history of use for the treatment of diseases such as neurasthenia, cardiovascular disorders, and cancer by the native people in northeast China. It is important to screen and identify the bioactive molecules from its root rapidly. Hereby,
To study the anti-inflammatory action and cellular mechanism of Oplopanax elatus.A hot water extract of OE (WOE) was prepared and a major constituent, syringin, was successfully isolated. Its content in WOE was found to be 214.0 µg/g dried plant (w/w). Bioreactor-cultured adventitious roots (ARs) of the endangered medicinal plant Oplopanax elatus Nakai is a novel alternative plant material. To utilize ARs in the product production, the present study investigated the anti-inflammatory effect of O. elatus ARs. In the in vivo experiment,
