3.5. After the paper is published, authors will be paid and presented with two copies of the current issue and a PDF file at no cost. The fee for copyright and payment for the article will be paid one-time. If you do not agree, please state clearly when the manuscript is submitted.
4. Manuscript preparation
The title should reflect the content of the manuscript. It should be concise, accurate and specific. Only the first letter of the title should be capitalized, except for proper nouns.
4.2. Authors and affiliations
Authors should be the researchers who have participated in the research work, and they are responsible for the content of the full paper. Authors also should respond the questions and comments raised by the editors. The author names should be separated by comma and the corresponding author should be marked with an asterisk. The detailed contact information (phone, fax and e-mail) should be listed and the corresponding author is responsible for the communication with editors. Evincive letter of affiliation should be provided when the copyright is changed. First letters of author names should be capitalized (e.g. Limei Zhang, Ping Wang). The names of foreign authors should follow international tradition. The different affiliations of the authors should be indicated by a superscript number after the author names.
The financial support and the contact information of the corresponding author (telephone, fax and e-mail) should be presented in footnotes.
The abstract should be a short paragraph that briefly describes the key contents of the full paper, not necessarily giving the remark and explanation at the level of detail found in Chemical Abstracts. It should be understood independently of the main body of the paper.
4.5. Graphical abstract
Authors should supply a graphical abstract when the paper is accepted. The graphical abstract is used to summarize the major point of article in a concise and pictorial form. It does not need to cover all contents of the paper. If necessary, authors may also provide a text abstract and the text only graphic abstract may not exceed 50 words. Please see the following examples.
Please provide 3–10 words or phrases as keywords, which are separated with comma. The keywords should represent the core content of the paper. General words and expressions should be avoided. First letters of all keywords should be capitalized.
4.7. The main body
A full research paper is generally consisting of three parts: introduction, experiment (materials and methods), and results and discussion. The three sections are separated clearly with a title of each section typed in the left of a line. Subtitles under each section are often used, which are placed at the left side of a separate line. Under each subtitle, further division can also be used with a title typed at the left of a line followed directly by a space and the text.
The introduction should concisely summarize the background of the research, raise the specific scientific questions the research is intended to solve, and describe the basic theory, research method, and experimental design. It should clearly state the purpose of the paper, especially the significance and novelty of the research.
Because of the diversity of research this journal publishes and the great variations of the experimental methods, the organizationstructure of this part can be different for different areas of research. Typically, this part should contain the general design, detailed experimental method, data collection, data processing and statistical analysis.
The resource, species and specification of the major materials should be provided. The names of drugs should be adopted following the guidelines of International Nonproprietary Names (INN)based on Chinese Approved Drug Names. The new drugs approved by the state food and drug administration should use their adopted names. The code names and brand names should not be used or rarely used. When a drug is described for the first time, the full English name should be used followed by its dose.
126.96.36.199. Research objects (animals, plants and microorganism)
For plants and medicinal herbs, the authors should give the scientific name (in italic) and indicate who identified the material and the location of the plant specimen. For animal study, the level of sanitation and the certification number should be indicated. Rats and mice should be hosted at the second level of sanitation at least. The genders, ages and weights of the animals or humans should be provided. Authors are advised to follow proper guidelines when animals or humans are used as research objects. Studies with human subjects can only be carried out after it is approved by the local ethnics committee of the responsible organization or it follows the rules stated in the Declaration of Helsinki of 1975 (revised in 2000). The patient names and their identification numbers in the hospital should be omitted.
The description of the research method should be as concise as possible. The significant number and the precision of the measured data should be consistent with the methods used. For a previously reported method, a reference citation is generally sufficient. For a modified method or a newly developed method, enough details should be provided to enable others to repeat the procedures. The data calculation process, software and the version, and the computer program used for theoretical calculation should be described.
188.8.131.52. Units of measurement and symbols of calculation
The units of measurement and symbols of calculation must follow the Chinese Calculation Unit Law (shortened for CalculationUnit Law) based on the international unit system. Please also refer to Quantity and Unit (Beijing, China Standard Press). Standardabbreviations can be used throughout the manuscript. Non-standard abbreviations must be defined in the text when it is first used.
Numbers are generally expressed by the Arabic number system. The numbers between 0.1–1000 can be written as is and scientific notation system is encouraged for more complicated numbers. Increase can be expressed in fold and decrease can be expressed in percentage. When describing a range of numbers, the use of the full number is preferred, for example 2×104–6×104 or (2–6)×104(not 2–6×104); 2%–6% (not 2–6%); 2 mm×3 mm×4 mm (not 2×3×4 mm).
The measured data should be consistent with the accuracy of the measuring instrument. Any error is only allowed at the last digit of the number. And the correction and revision of the significant numbers should be done in one time.
184.108.40.206. Tables and figures
Tables and figures should be designed reasonably. They should be understood without reference to the text. Tables and figures must be cited in the text and numbered sequentially in the order of appearance with Arabic numbers. It is still necessary writing “Table 1”or “Figure 1” even when there is only one table or one figure. The artwork should be prepared at the actual size that they are to appear (single-column width is 8.0 cm; double-column width is (10–17) cm).
The data plot should be presented in its original Excel, GraphPad PrismorOrigin figures, and chemical structures can be prepared with ChemDraw.
A title is required on top of the table. The tables should be placed at the left side of the page. Limit the use of punctuations in tables, align the numbers and texts neatly, and footnotes are indicated by superscript Roman letters a, b, c, etc.
220.127.116.11. NMR data
NMR data may be presented in either tables or in the text. Tables are preferred for complex NMR assignments and for series of compounds with full assignments. Full assignments are encouraged using 2D NMR techniques, especially for large, complex structures. The preferred order is: mp; [α]D; Rf values; spectral data (UV, IR); 1H NMR data; 13C NMR data; MS data. The following is the preferred format:
1H NMR (500 MHz, CDCl3) δ: 7.02 (d, 1H, J 8.7 Hz, NHCO), 5.93 (m, 2H, CH2CH3)… 13C NMR (75 MHz, D FONT-SIZE: 9pt; language: EN;">d6)δ: 158.4 (NHCO), 56.3 (CH2CH3) …HRMS calcd. for C15H20O3SNa (M+Na)+: 303.1025; found 303.1028…
4.7.3. Results and discussion
This section should include the newly obtained experimental results, conclusions, and limitations of the experiments. Especially these experimental conditions that cannot be controlled easily should be pointed out. The discussion should be in the context of previous findings and related with the objective, results, and conclusions of the experiments. Avoid repeating the results and do not review the literatures in this part. Speculative deductions and conclusions without supporting data and evidence are not allowed.
This section is optional. Sources of financial support may be recognized here or in a footnote on the title page. Persons, who made contributions to the research but not on the author list, could be listed here.
