prismatomeris sessiliflora/肺がん

The root of Prismatomeris connata has been used in China for centuries as the medicinal herb "Huang Gen" (HG), but its phytochemicals or active ingredients are not well understood. In this study, we performed chemical analysis of the ethyl acetate fraction of a HG ethanol extract. We thus isolated

HG30, a tetrahydroanthraquinone compound isolated from the roots of Prismatomeris connate, was previously shown to inhibit the proliferation of A549 cells. The aim of this study was to evaluate the antitumor activity of HG30 in two non-small cell lung cancer cell lines, A549 and H1299, and to

Two new anthraquinones, 4-hydroxy-1,2,3-trimethoxy-7-hydroxymethylanthracene-9,10-dione (1) and 1,2,3-trimethoxy-7-hydroxymethylanthracene-9,10- dione (2), were isolated from the roots of Prismatomeris connata, a Chinese medicinal herb. Their structures were elucidated by spectroscopic analysis.

Medicinal herbs are the preferred candidates for drug discovery against human diseases including cancer. The roots of Prismatomeris connata have been used in traditional herbal medicine to treat many health problems, particularly pneumoconiosis. This study was to test the anti-tumor activity of
