ABSTRACT

Objective To study the quality standard of Qingre-Chushi granules, including TLC identification of main components and ultra performance liquid chromatography determination of main components, so as to lay a foundation for further development of new drugs. Methods Seven constituents, including Gentianae Radix et Razoma, Scutellaria Radix, Plantaginis Herba, Rehmanniae Radix, Imperarae Rhizoma, Poria and Glycyrrhiza Radix et Rhizoma, were determined by TLC. The content of gentiopicroside and Baicalin in Gentiana officinalis and Scutellaria baicalensis was determined by UPLC on Acquity UPLC HSS T3C18 column (2.1 mm×100 mm, 1.7 μm) with acetonitrile-0.01% formic acid water as mobile phase and gradient elution. Results TLC was highly specific and could effectively identify Gentian, Scutellaria baicalensis, Plantain, Rehmannia glutinosa, Rhizoma cocos, and licorice. The results of UPLC assay showed that there was a good linear relationship between gentiopicroside and Baicalin in the range of 0.014-0.028 μg and 0.015-0.449 μg, and the recovery of the three concentrations were all up to standard. Conclusions TLC can be used to identify the seven components of Qingre-Chushi granules, and UPLC can be used to determine the contents of three indicators, which can control the quality of Qingre-Chushi granules.

ABSTRACT

Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical effect of Ginkgo biloba extract gel (Ginkgo biloba extract,EGB) and minocycline hydrochloride (Periocline) on periodontitis and their inhibition on putative periodontal pathogens.</p><p><b>METHODS</b>Thirty patients with moderate-to-severe periodontitis were selected. The patients were divided into an experimental group and a positive control group (minocycline hydrochloride). Supragingival and subgingival scaling were performed on all patients. Subgingival plaque samples were collected before treatment, 1 week, 2 months and 4 months after treatment. The four major periodontal pathogens Porphyromonas gingivalis (Pg), Bacteroides forsythus (Bf), Prevotella intermedia (Pi), Treponema denticola (Td) were detected by polymerase chain reaction. Clinical indexes plaque index (PLI), bleeding index (BI) and probing depth (PD), attachment loss (AL) were examined before treatment, 3 months and 6 months after treatment. The results were statistically analyzed.</p><p><b>RESULTS</b>The detection rates of the 4 periodontal pathogens were Td (83.3%), Tf (95.0%), Pi (80.0%), Pg (81.7% ) in experimental group and Td (83.3%), Tf (95.0%), Pi (80.0%), Pg (81.7%) in control group before treatment. The detection rates in experimental group were not significantly different with those in control group after treatment, except for the detection rate of Pg 1 week after treatment (P < 0.01, the detection of Pg was 56.7% in experimental group and 53.3% in control group 1 week after treatment). The PLI and BI were not significantly different between experimental group and control group after treatment (P > 0.05). The difference was statistically significant at 6 months after treatment [(3.5 ± 0.5) mm for experimental group and (3.2 ± 0.4) mm for control group, P = 0.00]. The mean of AL decreased with time. The difference was statistically significant at 6 months after treatment [ (4.5 ± 0.4) mm for experimental group and (4.3 ± 0.4) mm for control group at 6 months, P = 0.01].</p><p><b>CONCLUSIONS</b>The inhibition effects of EGB and minocycline hydrochloride were comparable for major periodontal pathogens within short term.</p>
