Study on Ranunculaceae herbal decoction pieces using X-ray diffraction / 中国中药杂志

The powder X-ray diffraction(PXRD) technique was used to investigate fourteen kinds of Ranunculaceae herbal decoction pieces(RHDP) recorded in Chinese Pharmacopoeia and to explore a novel PXRD quality control method for RHDP. The results indicated that only three RHDP-Paeoniae Radix Alba, Paeoniae Radix Rubra, and Moutan Cortex, contained calcium oxalate monodydrate(COM), whereas no COM existed in other eleven kinds of RHDP. The difference in PXRD for Paeoniae Radix Alba and Paeoniae Radix Rubra from different growing areas were investigated. The quantitative analysis method for COM was discussed by considering the water-boiling manufacturing process of herbal decoction pieces. The water-boiling experiments revealed that the PXRD peaks from COM crystals in RHDP were enhanced significantly after boiling. Paeoniae Radix Alba, Paeoniae Radix Rubra, Moutan Cortex, Aconiti Lateralis Radix Praeparata, Aconiti Radix, Aconiti Kusnezoffii Radix, and Anemone Raddeanae Rhizoma exhibited a similar series of broader peaks in the 2θ region of 15° to 35°, whose origins were discussed on the basis of chemical constituents RHDP reported by other researchers. These diffraction broader peaks most likely originated from periodic orientation of benzene ring in organic molecular crystals of aconitine-and paeonolum-based alkaloids and glycosides chemical constituents, subsequently, possibly from some other organic constituents. The PXRD technique can be used to rapidly identify Cimicifuga heracleifolia with an amorphous dispersion peak and C. dahurica with a sharp-peak feature. Climatidis Radix et Rhizoma exhibited a series of sharp PXRD peaks. The PXRD method can provide a valuable quality control method for RHDP.

Feasibility exploration of discriminating red yeast rice for different applications by secondary metabolite fingerprints / 药学学报

Though red yeast rice (RYR) has been used as medicine for centuries, few study has been reported about its biological activities related to traditional medicinal application and marketed RYR showed poor consistency in quality. In this study, with comprehensive investigation of their production processes and field acquisition samples including those from genuine producing area, an ultra performance liquid chromatographic (UPLC) method was firstly established to discriminate RYR for different applications based on their secondary metabolites fingerprint. It was performed on a CAPCELL CORE AQ column (100 mm×4.6 mm, 2.7 μm), with PDA (range: 200-650 nm, extracted: 237 nm) and ELSD detection. The mobile phase used was water (A) and acetonitrile (B) both containing 0.1% formic acid at gradient elution (0-15 min, 50% B→85% B (linear); 15-16 min, 85 % B→50% B (linear) and maintained until 21 min), with a flow rate of 0.5 mL∙min-1. The method established was fully validated in agreement with guidelines of Chinese Pharmacopeia. Common metabolites were found in RYR for same application and the fingerprints of RYR for food coloring or brewing from various manufacturers had similarities above 0.90. Meanwhile, significant differences were observed among the fingerprints for various applications and discrimination could be achieved by principal component analysis (PCA). Lovastatin was absence in RYRs for food coloring or brewing, and the fingerprint of traditional medicinal RYR was similar to that of RYR for brewing. However, standardization was required for RYR containing lovastatin because of their significant differences from various manufacturers in fingerprints and lovastatin content. The results demonstrated the feasibility to discriminate RYR for different applications by the secondary metabolites fingerprint method established in this study, which provides a scientific basis to investigate the relationship between biological activities of medicinal RYR and their corresponding secondary metabolites, and further aid their quality standardization and improvement.

Pharmacological network-based study on quality control of Carthamus tinctorius L. for safflower injection / 药学学报

We determined a component-target-disease network for Carthamus tinctorius L. and the key compounds, identified by topological analysis, were related to vasculitis, coronary heart and cerebrovascular disease. Based on these compounds, the chromatographic fingerprint of Carthamus tinctorius L. was established. Firstly, 132 compounds were obtained from TCMID and TCMSP databases. Their targets were predicted in the PharmMapp and HemMapper databases. CardioGenBase, Therapeutic Target Database and DisGeNET databases were used to collect targets of vasculitis, coronary heart disease and cerebrovascular disease. The corresponding relationships between component and target protein were established by mapping. Finally, the "component-target-disease" network was built with Cytoscape software. The core network and key nodes were analyzed with the Cytohubba plug-in. The results showed that the 24 key compounds were alpha-tocopherol, adenosine, quinone chalcone pigments such as hydroxysafflor yellow A, safflower yellow, quercetin, kaempferol and other flavonoids, organic acids such as stearic acid, linolenic acid, coumaric acid and cinnamic acid. This resulting chromatographic fingerprint of Carthamus tinctorius L. showed good consistency, and the core chemical compounds obtained by topological analysis of the network of "component-target-disease", could be used as quality control markers. Our research provides a new approach for the identification of quality control indicators in Chinese medicinal materials.

Comparison of Different Periodontal Healing of Critical Size Noncontained and Contained Intrabony Defects in Beagles / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Regenerative techniques help promote the formation of new attachment and bone filling in periodontal defects. However, the dimensions of intraosseous defects are a key determinant of periodontal regeneration outcomes. In this study, we evaluated the efficacy of use of anorganic bovine bone (ABB) graft in combination with collagen membrane (CM), to facilitate healing of noncontained (1-wall) and contained (3-wall) critical size periodontal defects.</p><p><b>METHODS</b>The study began on March 2013, and was completed on May 2014. One-wall (7 mm × 4 mm) and 3-wall (5 mm × 4 mm) intrabony periodontal defects were surgically created bilaterally in the mandibular third premolars and first molars in eight beagles. The defects were treated with ABB in combination with CM (ABB + CM group) or open flap debridement (OFD group). The animals were euthanized at 8-week postsurgery for histological analysis. Two independent Student's t-tests (1-wall [ABB + CM] vs. 1-wall [OFD] and 3-wall [ABB + CM] vs. 3-wall [OFD]) were used to assess between-group differences.</p><p><b>RESULTS</b>The mean new bone height in both 1- and 3-wall intrabony defects in the ABB + CM group was significantly greater than that in the OFD group (1-wall: 4.99 ± 0.70 mm vs. 3.01 ± 0.37 mm, P < 0.05; 3-wall: 3.11 ± 0.59 mm vs. 2.08 ± 0.24 mm, P < 0.05). The mean new cementum in 1-wall intrabony defects in the ABB + CM group was significantly greater than that in their counterparts in the OFD group (5.08 ± 0.68 mm vs. 1.16 ± 0.38 mm; P < 0.05). Likewise, only the 1-wall intrabony defect model showed a significant difference with respect to junctional epithelium between ABB + CM and OFD groups (0.67 ± 0.23 mm vs. 1.12 ± 0.28 mm, P < 0.05).</p><p><b>CONCLUSIONS</b>One-wall intrabony defects treated with ABB and CM did not show less periodontal regeneration than that in 3-wall intrabony defect. The noncontained 1-wall intrabony defect might be a more discriminative defect model for further research into periodontal regeneration.</p>

Application of microscopic spectroscopy in quality control of Niuhuang Qingxin pills / 中国中药杂志

Application of microscopic spectroscopy in quality control of Niuhuang Qingxin pills was discussed. First, microscopic characteristics specified by the statutory standard of Niuhuang Qingxin pills were summarized. Then new identification method was established for Dioscoreae Rhizoma, Saigae Tataricae Cornu, Cinnamomi Cortex and Saposhnikoviae Radix. Finally, microscopic spectroscopy was used for test of Dioscoreae Rhizoma's adulterant Dioscoreae Fordii Rhizoma.It was the first time for this technology being applied in adulteration test of Chinese patent medicine.The results showed that Saigae Tataricae Cornu was not detected in 2 batches of Niuhuang Qingxin pills from 1 manufacturer while Dioscoreae Fordii Rhizoma was detected in 3 batches of samples from 2 manufacturers. The proposed methods were accurate, simple, rapid, objective and economic, which offered a more comprehensive approach for quality control of Niuhuang Qingxin pills. It was indicated that conventional technology such as microscopic spectroscopy could play an important role in identification of traditional Chinese medicine whose index ingredient was deficient or tiny.

Discussion on Habitat Processing Method ofIndigo Naturalis / 世界科学技术-中医药现代化

Recently, there are many prominent problems about the quality ofIndigo Naturalis. To explore the underlying reasons, both ancient and modern herbal literatures were reviewed. Through the organization of recordings onIndigo Naturalis, the traditional process method required soaking and fermentation, stiring and depositing, foaming and shade drying. The currently usedIndigo Naturalis was mostly isolated and purified from crude deposit -“Cu-Dian.” The modern process technique ofIndigo Naturalis was gradually deviated from the traditional processing method. This paper also discussed the quality standards ofIndigo Naturalis. The author considered that the current standard on descriptions ofIndigo Naturalis characteristics was deviated from the traditional morphological features ofIndigo Naturalis, which should be further researched and verified. Therefore, this study provided certain references for the quality control and market supervision ofIndigo Naturalis.

Identification of Epmedii Folium and its counterfeit leaf of Quercus variabilis / 中国中药杂志

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.
