Rapid identification of Fritillariae Cirrhosae Bulbus and its adulterants by UPLC-ELSD fingerprint combined with chemometrics methods
In this study, a UPLC-ELSD fingerprint analysis with chemometric methods, including similarity analysis, hierarchical clustering analysis, and principal component analysis, were applied for the identification of FCB and its adulterants. Our results indicated that the combined method could efficiently identify and distinguish FCB from its adulterations. The proposed method provides a potential perspective for the quality control of traditional Chinese medicine. (Source: Biochemical Systematics and Ecology)

Spatial structure of genetic and chemical variation in native populations of the mile-a-minute weed Mikania micrantha
We examined the spatial distribution and potential relationship of genetic and volatile terpenoid diversity in 13 Mexican populations of Mikania micrantha (Asteraceae) from the Atlantic and Pacific watersheds using six specific microsatellites. A low genetic diversity was observed in all populations (H E = 0.00–0.37), which may be attributed to clonal reproduction and/or their marginal location relative to the whole species distribution in the Americas. We found a significant genetic differentiation between regions, and more genetic structure in Atlantic populations where a Mantel test also showed a pattern...

Two Delphinium ramosum chemotypes, their biogeographical distribution and potential toxicity
The objective of this study was to profile the alkaloid composition of D. ramosum throughout its geographical distribution using both field and herbarium specimens. Two alkaloid profiles were identified, one that contained significantly greater concentrations of the MSAL-type alkaloids than the other. Plants containing each respective alkaloid profile were unique in their geographical distribution. Populations of these two chemotypes will likely differ in their toxic potential and consequently pose different risks of poisoning when grazed by livestock species. This information has important implications in grazing manageme...

Publication date: June 2017 Source:Biochemical Systematics and Ecology, Volume 72 Author(s): Jun Dang, Li-jin Jiao, Wei-dong Wang, Jin-jin Pei, Yan-duo Tao, Yun Shao, Li-juan Mei, Qi-lan Wang, Li Zhang A phytochemical investigation of Saxifraga tangutica led to the isolation of 11 compounds, including eight diarylheptanoids (1–6, 10 and 11) and three phenylpropanoids (7–9). The chemical structures were established by extensive analysis of their MS and NMR spectroscopic data or comparison with literature data. In the present research, we report the isolated compounds 1–11, for the first time, in the speci...

Genetic variability and differentiation among the populations of Dice snake, Natrix tessellata (Sepentes, Colubridae) in the Iranian Plateau
Publication date: June 2017 Source:Biochemical Systematics and Ecology, Volume 72 Author(s): Eskandar Rastegar-Pouyani, Farnaz Ebrahimipour, Saeed Hosseinian The Dice snake, Natrix tessellate, is one of the widely distributed but poorly studied reptiles of the Iranian plateau. Here, we sequenced a partial fragment of Cyt b for 14 samples of Natrix tessellata from Iran. The data were added to the previously published data from GenBank. The phylogenetic analyses indicated that the Iranian populations of N. tessellata are well divided into two major clades. The north, eastern and NE populations of Dice snake in Iran in ...

Genetic diversity and fine-scale genetic structure in Hancornia speciosa Gomes (Apocynaceae)
Publication date: Available online 13 April 2017 Source:Biochemical Systematics and Ecology Author(s): Camila Fernanda Costa, Rosane Garcia Collevatti, Lázaro José Chaves, Jacqueline de Souza Lima, Thannya Nascimento Soares, Mariana Pires de Campos Telles We studied the genetic diversity and spatial genetic structure (SGS) of adult and juvenile individuals in a population of Hancornia speciosa in Central-West Brazil. For this, we sampled and mapped 113 adults and 100 juveniles in an area of 2.5 ha. Genomic DNA was obtained from leaves and seven microsatellite loci were used to genotype all individuals. ...

Molecular analysis of invasive Cichla (Perciformes: Cichlidae) populations from neotropical ecosystems
Publication date: June 2017 Source:Biochemical Systematics and Ecology, Volume 72 Author(s): Nathália Alves Diamante, Alessandra Valéria de Oliveira, Ana Cristina Petry, Paula Araújo Catelani, Fernando Mayer Pelicice, Sônia Maria Alves Pinto Prioli, Alberto José Prioli Invasive Cichla populations in the São João River basin were genetically analysed and compared with Cichla populations from other neotropical hydrographic basins. Polymorphic sequences within the mitochondrial DNA D-loop region confirmed the introduction of different populations to the regions under analysis. ...

Phytochemical and chemotaxonomic study on Dianella ensifolia (L.) DC
Publication date: June 2017 Source:Biochemical Systematics and Ecology, Volume 72 Author(s): Ben-qin Tang, Zhen-yang Chen, Jian-bo Sun, Simon Ming-yuen Lee, Jian-lin Lu Phytochemical investigation of the roots of Dianella ensifolia led to the isolation of eleven known compounds, including two aromatics (1, 2), two chromones (3, 4), and seven flavonoids (5–11). The structures of these compounds were elucidated on the basis of spectral analysis and comparison with data reported in literature. In the present research, all of the isolated compounds 1–11 were reported for the first time in the species D. ensif...

Genetic diversity and methylation polymorphism analysis of Chrysanthemum nankingense
In this study, phenotypic variants of C. nankingense were first identified by morphological traits. Using EST-SSR (simple sequence repeat) analysis, we detected some absent EST-SSRs. The percentage of AFLP (amplified fragment length polymorphism) polymorphic fragments was 78.2%, indicating high genetic diversity. To evaluate the genome methylation level and methylation polymorphism, we used the MSAP (methylation-sensitive amplification polymorphism) technique to analyze the 30 C. nankingense lines. The total DNA methylation level ranged from 54.6% to 62.6%. Most of the MSAP-methylated fragments (97%) were polymorphic ...

The mitochondrial genome of Gatzara jezoensis (Neuroptera: Myrmeleontidae) and phylogenetic analysis of Neuroptera
Publication date: April 2017 Source:Biochemical Systematics and Ecology, Volume 71 Author(s): Lulu Zhang, Jing Yang Phylogenetic relationship within Neuroptera is controversial, particularly for the various hypotheses based on both morphological and molecular evidence. In the present study, we determined the complete mitochondrial genome (mitogenome) of Gatzara jezoensis, which is the second representative of the tribe Dendroleontini. The G. jezoensis mitogenome contained the conserved set of 37 mitochondrial genes and a putative control region, with a conserved gene arrangement which was similar to that of most sequ...
