摘要 | Pharmacologically active xanthone compounds isolated from Swertia przewalskii pissjauk were well separated by capillary electrophoresis (CE) within 5 min, using a running buffer of 25 mM disodium tetraborate at pH 9.0. Quantitative determination was shown to be possible because regression equations revealed a linear relationship between the peak area of each constituent and its concentration, with correlation coefficients of 0.9972-0.9994. The relative standard deviations were between 0.44%-0.73% for migration times and 2.52%-4.28% for peak areas. The dissociation constant of 1,7-O-beta-D-glucopyranosyl-8-hydroxy-3,7-dimethoxyxanthone, 1,8-dihydroxy-3, 7-dimethoxy-xanthone and 1,7-dihydroxy-3,8-dimethoxyxanthone were also measured by the CE method, giving a value of 9.04, 8.94, and 8.59, respectively.; Pharmacologically active xanthone compounds isolated from Swertia przewalskii pissjauk were well separated by capillary electrophoresis (CE) within 5 min, using a running buffer of 25 mM disodium tetraborate at pH 9.0.
