The anti-rheumatoid arthritis property of the folk medicine Dianbaizhu (Gaultheria leucocarpa var. yunnanensis, Ericaceae).[Pubmed: 25632482]
The Chinese folk medicine Dianbaizhu, consisting of Gaultheria species, is widely used for the treatment of rheumatoid arthritis by several minority nationalities. The species and plant parts of this genus used as Dianbaizhu in clinical application are confused. In order to elucidate the species and the medicinal parts, as well as to ascertain the effective components and the probable optimal source of Dianbaizhu, the different plant parts and polarity fractions of its mainstream species, G. leucocarpa var. yunnanensis were investigated. The inhibition of nitric oxide and tumor necrosis factor produced in macrophage J774 were used to assess the anti-inflammatory effect of those samples. G. leucocarpa var. yunnanensis may be the preferred species for anti-RA effect. The underground parts of this taxon showed the best anti-inflammatory and anti-RA activities; the n-butanol and water fractions of the underground parts may be the most anti-RA active.
Simultaneous determination of active ingredients in ethnomedicine Gaultheria leucocarpa var. yunnanensis and its medicinal preparation by capillary electrophoresis with electrochemical detection.[Pubmed: 17988450]
A simple and rapid capillary electrophoresis (CE) with electrcochemical detection (ED) method has been established for the simultaneous determination of seven active ingredients in the stems and roots of Gaultheria leucocarpa var. yunnanensis and its medicinal preparation, including (+)-catechin, rutin, gentisic acid, vallinic acid, salicylic acid, quercetin, and protocatechuic acid. The effects of working potential, pH, and concentration of running buffer, separation voltage, and injection time on CE-ED are systematically investigated. Under the optimum conditions, the seven analytes could be completely separated within 23 min in a borax running buffer (pH 8.7). A good linear relationship is obtained over three orders of magnitude with detection limits (signal-to-noise ratio=3) ranging from 5x10(-8) g/mL to 3x10(-7) g/mL for the analytes. The proposed method is successfully used in the analysis of real samples after a relatively simple extraction procedure, and the assay results are satisfactory.
