ABSTRACT

Echiophis brunneus, comúnmente conocida como anguila pecosa, es una especie bentónica costera de la familia Ophichthidae. Su distribución se reporta para el Pacífico Oriental desde el Golfo de California (EE. UU.) hasta el Golfo de Guayaquil (Ecuador). Se reporta por primera vez la presencia de E. brunneus en el norte del Perú a partir de tres ejemplares capturados. Así mismo se registra una nueva talla máxima para la especie y se adiciona la secuencia COI a la base de datos BoldSystems. Una de las principales características para su determinación fue la presencia del diente canino grande localizado en la zona distal del vómer. Las distancias genéticas entre E. brunneus con E. punctifer y E. intertinctus fueron de 0.087±0.013 y 0.095±0.014 respectivamente. Con este trabajo se amplía la distribución geográfica de E. brunneus hasta Salaverry (08°13'28"S, 78°59'22"W), así mismo sugerimos el posible establecimiento de una población de esta especie en la costa norte del Perú.


Echiophis brunneus, commonly known as fangjaw eel, is a coastal benthic species belonging to the Ophichthidae family. Its distribution is reported to be in the Eastern Pacific from the Gulf of California (USA) to the Gulf of Guayaquil (Ecuador). In this study, we report for the first time the presence of E. brunneus based on three specimens captured in northern Peru. Additionally, a new maximum size for the species is recorded, and the first COI sequence is added to the BoldSystems database. One of the main characteristics for its determination was the presence of a large canine tooth located in the distal area of the vomer. The genetic distances between E. brunneus with E. punctifer and E. intertinctus were 0.087±0.013 and 0.095±0.014 respectively. With this work the geographical distribution of E. brunneus is extended to Salaverry (08°13'28"S, 78°59'22"W). We also suggest the possible establishment of a population of this species on the northern coast of Peru.

ABSTRACT

From the perspective of market classification of Cnidii Fructus, this paper revealed the scientific connotation of evaluating the quality grade of Cnidii Fructus by its appearance traits. Thirty batches of Cnidii Fructus in different grades were selected as the research objects. The canonical correlation analysis and principal component analysis(PCA) were used to explore the measurement values of 15 appearance traits and intrinsic content indexes. The results of correlation analysis showed that except the aspect ratio, the 5 appearance trait indexes(length, width, 1 000-grain weight, broken grain weight proportion, and chroma) and 9 internal content indexes(the content of moisture, total ash, acid insoluble ash, osthole, imperatorin, 5-methoxy psoralen, isopimpinellin, xanthotoxin, and xanthotol) showed significant correlation to varying degrees. In addition, there was a significant positive correlation between the first typical variable U_1 composed of appearance traits and the first typical variable V_1 composed of internal content indexes(CR_1=0.963, P<0.01). The results of PCA showed that the classification results of appearance traits for 30 batches of Cnidii Fructus were consistent with the actual information of the samples. Under the same analysis conditions, 30 batches of Cnidii Fructus were reclassified by 9 groups of internal content indexes, and the analysis results were consistent. From the classification standard of the appearance traits of the system study, the statistical results of 6 appearance traits of Cnidii Fructus showed a correlation with grades. There was a good correlation between the appearance and the internal content of Cnidii Fructus, and the appearance quality effectively predicted the level of the internal content. There is a certain scientific basis for the quality classification of Cnidii Fructus by main appearance traits. Appearance classification can replace quality grading to realize the "quality evaluation through morphological identification" of Cnidii Fructus.

ABSTRACT

Objective: To provide scientific evidence for the identification of Prinsepiae Nux by observing the characteristics and microscopic characteristics, which may be of relevance to the compilation of 2020 edition of Chinese Pharmacopoeia. Methods: The pharmacognosy of fruit core from 12 batches of P. uniflora and nine batches of P. uniflora var. serrata were studied by character identification, micro-morphological identification, conventional microscopic identification and polarized light microscopic identification. Results: From the shape, size, color, surface characteristics, texture, cross-section, qi, taste and other aspects, the characteristics of pupae and dentate wood were observed and studied. For the hard texture and after the softening treatment, it is still not suitable to prepare cross-sections to observe the complete plant tissue structure and determine the medicinal material of the tissue site. Using free-hand slicing technology of positioning and taking materials can accurately obtain the microscopic characteristics of plant tissue in specific parts; A medicinal material that integrates a large group of bundles and is difficult to show the complete morphological characteristics of a single cell after pulverization. Using dissociated tissue filming technology, it is possible to obtain clear, complete, and non-overlapping single cell full-spectrum and characteristic information. Conclusion: Micro-morphological characteristics (endocarp,cotyledon and seed coat)were obtained for the first time. the results of microscopic identification and micro-morphological identification fill in the blank of color image information. Stone cells of endocarp can be used as specific markers for microscopic identifying Prinsepiae Nux.

ABSTRACT

Objective: To develop an accurate and effective method to identify the original animals of Chinese medicine Pheretima (Dilong in Chinese) and its adulterants by using mitochondrial genes, cytochrome coxidase I (CO I) and 16 S rRNA as DNA barcoding sequences to certify and improve morphological analysis. Methods: A total of 66 samples were initially identified according to their morphological characteristics, and then their CO I and 16 S rRNA sequences were simultaneously amplified for DNA barcoding. The two gene sequences were amplified with improved primers. One-step double PCR was used and the experimental conditions were optimized. The genetic distance among and within species of Pheretima and its hybrids was calculated by MEGA 5.1. The N-J tree was constructed based on K2P model. Results: Combined with morphological identification, CO I and 16S rRNA double DNA barcoding identification can accurately identify Pheretima and its adulterants. Conclusion: Morphological identification is the basis of molecular identification. Molecular identification can be a powerful supplement to the morphological identification. The combination of molecular identification and morphological identification can increase the accuracy of the identification of the original animals of Pheretima and its adulterants. Double DNA barcoding can also provide a solution for the identification of the medicinal materials of Pheretima and other animal medicinal materials.

ABSTRACT

The combination of morphological characteristics and DNA barcodes was used to a systematic study of Hippocampus spinosissimus,laying the foundation for rapid and accurate identification for the medical seahorse species. According to the reported literature and observation on seahorse samples,the typical characteristics of the H. spinosissimus include highly developed spiny,much short nose,single or double cheeks and strongly developed spines bordering pouch. Genomic DNAs of H. spinosissimus and other related seahorse species were extracted using the TIANamp Marine Animals DNA Kit. The COⅠ and ATP6 genes were amplified and sequenced in both directions. After the verification by Blast,the GC content,intraspecific and interspecific genetic distance,and the Neighbor joining( NJ) phylogenetic trees were analyzed by MEGA 7. The lengths of the COⅠ and ATP6 genes were 649 bp and 602-603 bp,respectively,with the average GC content of 39. 96% and 35. 37%. The maximum intraspecific genetic distances in H. spinosissimus based on COⅠ and ATP were both far less than the minimum interspecific genetic distance between H. spinosissimus and other seahorses,suggesting a significant barcoding gap. NJ analysis results of COⅠ and ATP6 exhibited that all H. spinosissimus species clustered together,indicating that the two DNA barcode could identify H. spinosissimus from other seahorses accurately and quickly. In addition,H. spinosissimus shared a close genetic relationship between H. kelloggi according to the NJ tree. Furthermore,there exits three stable subgroup structure of H. spinosissimus,indicating that COⅠ and ATP6 barcodes could be applied the indicator for the geographical ecology research of H. spinosissimus. The results obtained the typical morphological and molecular identification characteristics of H. spinosissimus,which played central roles for the development of species identification. This study provides an important basis data for expanding the medical seahorse resources and ensuring the safety of clinical medicine.

ABSTRACT

The morphological identification, chemical component analysis, and DNA barcode determination were investigated on Genus Mentha (including Mentha haplocalyx Briq., Mentha piperita Linn., Mentha spicata Linn. and Mentha cultivated) in order to reveal the origin of Herba Mentha as a drug, and ensure the accuracy in clinic application. The morphological characters, chemical composition analysis by GC-MS/MS and DNA content measure by polymerase chain reaction (PCR) were reported in this study for inter- or intra- species divergence. Based on the morphology, axillary verticillasters was recognized as the typical character for Mentha haplocalyx Briq. Carvone was used as an index component for chemical composition analysis of Mentha spicata Linn. Gene clustering analysis divided 22 batches of samples into two molecular groups. Mentha haplocalyx Briq. is distinguishably different from Mentha spicata Linn. Mentha piperita Linn. and other cultivated plants were distributed between these two species. The results obtained by morphological identification, chemical composition analysis, and DNA barcode determination show good correlations, but each identification method has its limit. In view of the fact that hybridization of the plants in Genus Mentha is common, identification relying on only one method is not recommended.

ABSTRACT

OBJECTIVE: To obtain the key identification information of Hippocampus barbouri (H. barbouri), investigate the pharmacognosy of the seahorse adulteration H. barbouri, using the combination of morphological and DNA barcoding technique. METHODS: Typical morphological characteristics of H. barbouri were studied based on the observations according to the previous reports and traditional pharmacognosy methods. Genomic DNAs of H. barbouri and other related seahorse species were extracted and the DNA barcoding genes of COI, 16S and ATP6 sequences were amplified and sequenced, respectively. In order to determine advantages of three barcodes for the identification of hippocampus, MEGA 7 was performed to analyze the intraspecific and interspecific distances and construct the NJ phylogenetic trees based on three different barcoding genes. RESULTS: The most typical distinguishing features of H. barbouri included the streak of the nose, five radial lines in the eyelid, and the long and short intervals of the tail thorns. The lengths of COI, 16S and ATP6 sequences were 649-650, 574 and 603 bp, respectively, with the maximum K2P intraspecific distances were 0.012, 0.003 and 0.003, respectively. The intraspecific distances of the three barcodes were far smaller than the corresponding minimum K2P interspecific distances of H. barbouri and other seven related seahorse species, existing an obvious barcoding gap. The NJ phylogenetic trees based on COI, 16S and ATP6 sequences showed that H. barbouri samples formed of a group indicating that H. barbouri could be distinguished from other seahorse species through the three DNA barcoding markers. In addition, H. barbouri showed close genetic relationship with H. histrix according to the NJ trees. Furthermore, the NJ tree structures of COI and ATP6 were more stable than that of 16S. CONCLUSION: The pharmacognostical investigation bases on the morphological identification and DNA barcodes obtained the key identification information of H. barbouri, providing the possibility for quick and accurate identification of this species. The COI, 16S and ATP6 barcoding genes can be used for further molecular identification markers for seahorse species. This study provides a new technical method for the development and quality control of hippocampus.

ABSTRACT

Objective: Cynanchum stauntonii and Cynanchum glaucescens are botanical species of Baiqian (Cynanchi Stauntonii Rhizoma et Radix) in Chinese Pharmacopoeia, in which, however, there are no microscopic identification. Therefore, we provided the morphological and microscopic identification of the crude drug for updating Chinese Pharmacopoeia. Methods: Twelve batches of C. stauntonii and three batches of C. glaucescens and their crude drugs were taxonomically, morphologically, and microscopically examined. Results: Taxonomically, C. stauntonii had narrowly lanceolate leaves with acuminate apex and 5mm long petiole; Whereas C. glaucescens was oblong-lanceolate or oblong with rounded or acute apex in leaves, and had very short or no petiole. Morphologically, rhizomes of C. stauntonii and C. glaucescens both had hollow pith, but the hollow pith occupied about a half of the rhizome's diameter in C. stauntonii, whereas only a very small proportion of the overall diameter in C. glaucescens. Moreover, microscopic observation showed the difference in the proportion of xylem and in rhizome transverse-sections of the two species along with the difference in the size of the pith. Finally, laticifers and rhizome epidermal secretory cells were present in the powders of C. stauntonii, but absent from C. glaucescens. Conclusion: Based on observation of morphological and microscopic characteristics, the two species can be distinguished by the size of the pith, proportion of xylem of rhizomes, and crude drug powder characters such as laticifers and secretory cells.

ABSTRACT

Rhizoma et Radix Notopterygii is a rare and endangered Chinese medicine. In the collection of Notopterygium franchetii fruits, we collected a sample of N. forrestii , which is a spurious breed. Fruits of N. franchetii and N. forrestii are very similar in morphology and can be easily confused. Until now the morphological identification of the fruits of Notopterygium has not been reported. To provide a scientific basis for the identification of N. franchetii and N. forrestii fruits, the morphology and microscopic identification were studied in this paper. In this study, stereomicroscope and paraffin sections were used to compare the morphological characteristics and microscopic characteristics of these two fruits. Our results showed that these two fruits were different in size, surface texture and the number of vertical edges on the back. These traits can be used as diagnostic characteristic of these two fruits. The difference between the number of tubing and the endosperm cell contents can be used as microscopic identification features. The above discriminative characteristics can distinguish the two fruits and provide scientific basis for the identification and germplasm evaluation of Notopterygium fruits.

ABSTRACT

Moghania mainly grows in Yunnan and Guangxi, and is a kind of traditional Zhuang medicine in China. It is used to treat dispelling wind and dampness, strengthen bones and muscles, and promote blood circulation and detoxification. Moghania is also well known for its edible and medical value in folk. Currently Moghania medicinal plants are recorded in the appendix of China Pharmacopoeia and some local standards, but there is no content about the quality standard. We need to improve the quality standard to make it more accurate and specific for the multi-origin characteristics of Moghania. The literatures on Moghania were analyzed and summarized in terms of characteristics, microscopic identification, thin layer chromatography (TLC), fingerprinting, and molecular identification. The analysis result showed that the primary quality control mode of Moghania is mainly based on multi-index synchronization, total composition and fingerprints. The application of TLC, UV, HPLC, infrared spectroscopy (IR), gas chromatography-mass spectrometry (GC-MS), inductively coupled plasma atomic emission spectrometry (ICP-AES) and inter-simple sequence repeats-poly-merase chain reaction (ISSR-PCR) molecular markers in Moghania quality control has been investigated systemically. These results provided references for the systematical study and quality control of Moghania resource.

ABSTRACT

OBJECTIVE: To explore a set of identification methods of discriminating Bupleurum scorzonerifolium from its adulterant Bupleuru bicaule. METHODS: Methods of morphological comparison of plant samples with specimens, macroscopic identification of the roots, TLC identification of the root extracts, and DNA molecular identification by ITS2 sequence were applied. RESULTS: There were distinctive differences in the morphological, macroscopic, and TLC characteristics between B. chinense and B. scorzomerifolium. The DNA of ITS2 sequence was able to be identified by measuring their mean intraspecific genetic distance (K-2-P distance) which was lower than their mean interspecific genetic distance. In the cluster dendrogram, both of them showed monophyletic property and could be distinguished from other adulterants. CONCLUSION: On the basis of comparison of Bupleurum scorzonerifolium and its adulterant Bupleurum bicaule, the main identification features were summarized by a combination of original plant morphology, macroscopic identification of the roots, TLC identification, and DNA molecular identification methods. DNA identification technology is an important supplement of the traditional identification methods, which may have great potential and application prospect in origin identification of medicinal plants.
