Simultaneous determination of seven components in Qibaomeiran pill by HPLC-DAD.

30 Aug 2009 A high-performance liquid chromatography coupled with photo diode array detection method is developed for simultaneous determination of seven active components in Qibaomeiran pill, including rutin, 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glycoside, ... Read more...

Positive correlations between hypericin and putative precursors detected in the quantitative secondary metabolite spectrum of Hypericum.

12 Aug 2009 A spectrum of eight pharmacologically important secondary compounds, all putatively belonging to the polyketide pathway (hypericin, pseudohypericin, emodin, hyperforin, hyperoside, rutin, quercetin, and quercitrin) were analyzed in several ... Read more...

Gold nanoparticles prepared using cape aloe active components.

5 Jul 2009 A novel use of two components of Cape aloe, aloin A and aloesin, acting as stabilizers in the preparation of gold and silver nanoparticles, is reported. Stable water-soluble particles of different size and shape are prepared by varying the reaction ... Read more...
