Characterization, Comparison of Two New Mitogenomes of Crocodile Newts (Caudata: Salamandridae), and Phylogenetic Implications.

Mitochondrial genomes (mitogenomes) are valuable resources in molecular and evolutionary studies, such as phylogeny and population genetics. The complete mitogenomes of two crocodile newts, and , were sequenced, assembled, and annotated for the first time using next-generation sequencing. The complete mitogenomes of and were 16,265 bp and 16,259 bp in lengths, which both composed of 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and 1 control region.

[Research hotspots and trends of Hedysari Radix: based on CiteSpace knowledge map].

This study aims to summarize the research hotspots of Hedysari Radix and predict the research trend with bibliometric methods, which is expected to serve as a reference for future research. CiteSpace V 5.8.

(Dryopteridaceae), a new species from Hunan, China.

, a new species growing on limestone in the Wulingshan Mountains, Hunan, China, is described and illustrated. This species is most similar to and on general morphological traits, such as the form of scales, rhizome and sori, but differs by the number of vascular bundles at the base of the petiole, length to width ratio of lamina, stalk length of basal pinnae, division of the lamina, apex form of the pinnule and habitat. Moreover, molecular phylogenetic analysis using the chloroplast L gene suggested that , as the sister group of , is a monophyletic clade.

[Study on drug properties and syndrome-symptom-formula-herb network of traditional Chinese medicine in treatment of effort angina pectoris based on data visualization].

This article aims to explore drug properties and syndrome-symptom-formula-herb network of traditional Chinese medicine(TCM) in the treatment of effort angina pectoris based on data visualization, and provide useful references for clinical diagnosis and treatment. Literatures about TCM formula for effort angina pectoris from databases of CNKI, WanFang, VIP, and CBM were retrieved from the database-building to August 31, 2019. The name of syndromes, symptoms, formulas, and herbs were standardized, and the corresponding databases were established.

[Research on the Correlation Between Soil Mineral Elements and NIR Fingerprint of Angelica sinensis].

Objective: To investigate the correlation between soil mineral elements and NIR fingerprint of Angelica sinensis.

Methods: The fingerprint of 130 batches of Angelica sinensis from 12 production regions were determined by near infrared spectra with integrating sphere and diffuse device of near infrared spectrometer. The determination of 15 kinds of mineral elements in the corresponding origin of soil mass fraction were determined by atomic absorption spectrometry or inductively coupled plasma mass spectrometry, grey correlation analysis and multivariate nonlinear regression method were used to analyze.

[Correlation Analysis Between Common Peaks of Angelica sinensis HPLC Fingerprint and Mineral Elements in Its Growing Soil].

Objective: To investigate the correlation between common peaks of Angelica sinensis HPLC fingerprint and mineral elements in its growing soil.

Methods: The fingerprints of 120 batches of Angelica sinensis from 12 habitats were determined by HPLC. The contents of Pb, As, Cr, Sb, Hg, Cu, Cd, Ni, Zn, Mg, Mn, Ca, Fe, Na and K in corresponding soil were determined by ICP-MS and AAS.

[NIR Fingerprints of Different Medicinal Parts of Angelicae Sinensis Radix].

Objective: To investigate the spectrum characteristics of near-intrared dittuse retlectance spectroscopy (NIR) fingerprint of different medicinal parts of Angelicae Sinensis Radix.

Methods: 96 batches of samples were collected from 14 counties of Gansu Province and Yunnan Province. The NIR fingerprints were collected by integrated sphere.

[Study on mineral elements distribution in soil of Angelica sinensis producing regions and its relationship with altitude and soil types].

Objective: To investigate the distribution characteristics of mineral elements in the soil of Angelica sinensis producing regions and its relationship with altitude and soil types.

Methods: The contents of 15 mineral elements in 103 batches of soil from 13 counties were determined by ICP-MS or AAS. Pearson correlation analysis, partial correlation analysis and systematical cluster analysis were used to analyze the data.

[Application of entropy-weight TOPSIS model in synthetical quality evaluation of Angelica sinensis growing in Gansu Province].

Objective: To investigate the establishment and application methods of entropy-weight TOPSIS model in synthetical quality evaluation of traditional Chinese medicine with Angelica sinensis growing in Gansu Province as an example.

Methods: The contents of ferulic acid, 3-butylphthalide, Z-butylidenephthalide, Z-ligustilide, linolic acid, volatile oil, and ethanol soluble extractive were used as an evaluation index set. The weights of each evaluation index were determined by information entropy method.
