A high-performance liquid chromatographic method was developed for electrospray mass spectrometric analysis of ginsenosides in Panax ginseng roots. The analyses were performed on a reversed-phase C18 column using a binary eluent (aqueous 8 mM NH4OAc, buffered to pH 7 with NH4OH-acetonitrile) under gradient conditions. Twenty-five ginsenosides could be(More)
This paper is a comparative analysis of the telecommunications policy-making process in China and India. As two of the largest emerging market economies, the telecommunications systems in the two countries have attracted an enormous amount of research attention. However, much of the existing literature focuses on the specifics of telecommunications(More)

A liquid chromatographic method was developed and validated for the determination of ginsenosides in Panax ginseng roots by using evaporative light-scattering detection. Eighteen ginsenosides were separated on a reversed-phase C18 column with water-ammonium acetate-acetonitrile as the mobile phase. The method is suitable for the routine determination of(More)
