5. Preparation of Manuscripts

(a) General Considerations. Manuscripts submitted to Natural Product Sciences should contain significant, unpublished, and original data not being considered simultaneously for publication elsewhere. The manuscripts should be prepared in clear, concise English. It should be double-spaced on A4 or letter size with 2.5 cm margin on all sides (text font size 12). The responsibility for all aspects of manuscript preparation depends on the authors. Submit your text in DOC/DOCX format. Figures or tables can be attached within document or can be submitted as separate files. Locate tables and figures after main text and list figure and table legends separately before the first table/figure. Insert special characters instead of changing fonts when special characters (e.g. Greek letters) are required. Protocols used to generate animal and/or human experimental data should be approved by an authorized Institutional Animal Care Committee and/or Human Experimentation Committee.

(b) Title Page. The title should be chosen carefully to provide information on the contents. The title should appear on a separate page and should be followed by the author names and the institution name and address. The title, author name(s), and affiliations should all appear on their own respective line of text. Place an asterisk after the name of the author to whom enquiries regarding the paper should be directed and include that author’s telephone and fax numbers and e-mail address. Author affiliations must be footnoted using Arabic numbers (1, 2, 3, …).

(c) Abstract. It should be written to summarize purpose, method, result and conclusion of the research. The abstract should not exceed 200 words for research articles and reviews. Compounds mentioned in the abstract, and given as specific Arabic numerals that are bolded in the text, should also be accompanied in the abstract by the same bolded numerals. The abstract should be on a separate page and should be provided with the bolded heading “Abstract

(d) Keywords. Please provide 2~6 keywords that reflect the scientific content of your manuscript.

(e) Introduction. The manuscript should include an introduction under the bolded heading “Introduction” starting the purpose of the investigation and relating manuscript to similar research.

(f) Experimental. To enable others to repeat the experiments, the procedures of experiments should be described in detail. Authors should describe in detail for the novel experimental procedures, but known procedures from previous papers should be referred by literature citation. Animal and/or human studies should declare that the study was performed under approval of protocol from the committee and the institution.

The presentation of specific details about instruments used, sources of specialized chemicals, and related experimental details should be incorporated into the text of the Experimental Section as a paragraph headed General Experimental Procedures. The general order for inclusion should be as follows: melting points; optical rotations; UV spectra; CD spectra; IR spectra; NMR spectra; mass spectra; and chromatographic and other techniques.

In a separate paragraph, experimental biological material should be reported as authenticated if cultivated or from a natural habitat, and the herbarium deposit site and voucher number should be recorded. The month and year when the organisms were collected should be stated, and it is recommended that the exact collection location be provided using a GPS navigation tool. All microorganisms used experimentally should bear a strain designation number and the culture collection in which they are deposited. The scientific name (genus, species, authority citation, and family) should be presented when first mentioned in the body of the manuscript. Genus and species names should be italicized.

When physical and spectroscopic data are presented in the body of the manuscript, the following general style must be used (with the various commonly used techniques presented in this same order):

Actinofuranone C (1) - White powder. [α]20D : -10.5 (c 0.1, MeOH); UV (MeOH) λmax (log ε) 231 (3.9), 282 (3.7) nm; IR (neat) νmax 3383, 2924, 1601, 1357, 970 cm-1; 1H and 13C NMR (CD3OD) see Table 1; HRFABMS m/z 363.2162 [M-H] (calcd for C21H31O5, 363.2171).

Valinic acid (2) - 1H NMR (CD3OD, 400 MHz): δ 7.55 (1H, dd, J = 8.8, 2.0 Hz, H-1), 7.55 (1H, d, J = 2.0 Hz, H-2), 6.83 (1H, d, J = 8.8 Hz, H-5), 3.89 (3H, s, OCH3); 13C NMR (CD3OD, 100 MHz) δ 169.0 (C-7), 151.4 (C-4), 147.4 (C-3), 124.0 (C-6), 122.0 (C-1), 114.6 (C-5), 112.5 (C-2), 55.1 (OCH3); EI-MS m/z 168 [M]+.

(g) Abbreviations. Authors should write abbreviations without periods. Standard abbreviations should be used throughout the manuscript and nonstandard abbreviations should be kept to a minimum and must be defined in the text following their first use.

(h) Results and Discussion. The “Results and Discussion” should be presented as a coherent whole section, in which the results are presented concisely. The discussion should interpret the results and relate them to existing knowledge in the field in as clear and brief a fashion as possible. Tables and figures should be designed to maximize the presentation and comprehension of the experimental data. For Full Articles of unusual length, subheadings may be included within the “Results and Discussion” section. The major heading “Results and Discussion” should be bolded, with the text starting on the line following. Subheadings are indented, followed by a period, and are a mix of uppercase and lowercase letters. The text follows on the same line as the subheading. The results should be presented concisely with tables and figures. Authors should pay attention not to use same data in more than one figure or in both a figure and a table. The detailed interpretation regarding results should be handled in discussion part. However, it may be desirable to combine results and discussion in a single section.

(i) Acknowledgments. The Acknowledgment section should include credits [initial(s) and last name] for technical assistance, financial support, and other appropriate recognition.

(j) References and Notes. References to the literature and all notes, regardless of their nature, should be numbered in order of appearance in the manuscript and cited in the text with superscript numbers. Each reference may have its own citation number, or alternatively, references referring to the same topic may be grouped under a common number using alphabetical subdesignations (e.g., 1a, 1b, 1c, etc.). The number of references and notes should not generally exceed 25 for a research article. Use ISO standard abbreviated journal title. Journal abbreviations can be found in the ISI Web of Knowledge website ( Each note should be assigned its own number. References and notes should follow the format shown:

(1) Kuang, H.-X.; Yang, B.-Y.; Xia, Y.-G.; Feng, W.-S. Arch. Pharm. Res. 2008, 31, 1094-1097.
(2) Lee, I. K.; Kim, K. H.; Lee, S. Y.; Choi, S. U.; Lee, K. R. Chem. Pharm. Bull. 2011, 59, 773-777.
(3) Field, L. D.; Sternhell, S.; Kalman, J. R. Organic Structures from Spectra; John Wiley & Sons: United Kingdom, 2013; p 93.

(5) Kaneko, I.; Minekura, H.; Takeuchi, Y.; Nakamura, T.; Haruyama, H. PCT Intl. 1994, 94-19481.

The author is responsible for the accuracy and completeness of all references. In particular, authors must cite all of the references from their own work on a particular topic, such as all papers published or submitted on the constituents of a given organism under consideration. The author should supply the Editor with copies of related manuscripts that are cited as “in press” or “submitted” for use by the editors and the reviewers in evaluating the manuscript under consideration.

(k) Tables. Tables should be numbered consecutively with Arabic numerals. Use a brief title and a concise heading for each column. SI units are preferred and data should be presented with significant figures. Footnote can be used and it should be given in lower case letter designations and cited in the tables as italicized superscripts. All tables should be cited in the text.

(l) Illustrations. The quality of the illustration of original will determine the quality of the illustrations printed in author’s paper. Preferred formats for graphics and artwork are TIFF (tagged image file format) and EPS (Encapsulated PostScript). Illustrations must fit a one- or two-column format on the journal page however single column illustrations are preferred for the efficient use of journal space.

  Single (preferred) Double
Minimum Width   9 cm (3.5 in)
Maximum Width 8 cm (3.125 in) 16.5 cm (6.5 in)
Maximum Depth 23 cm (9 in) 23 cm (9 in)

For best results, submit illustrations in the actual size at which they should appear in the journal. Original illustrations which do not need to be reduced to fit a single or double column will yield the best quality. Lettering should be no smaller than 4.5 points. (Helvetica type works well for lettering.) Lines should not be thinner than 0.5 point. Lettering and lines should be of uniform density. If you must submit artwork that must be reduced, use larger lettering and thicker lines so that, when reduced, the artwork meets the above-mentioned parameters. Avoid using complex textures and shadings to achieve a three-dimensional effect. To show a pattern, choose a simple cross-hatch design.

Color. All color figures will be reproduced in full color in the online edition of the journal at no cost to the authors. Authors are required to pay the cost of reproducing color figures in print. Authors are encouraged to submit color illustrations that highlight the text and convey essential scientific information. For best reproduction, bright, clear colors should be used.

(m) Chemical Structures. Structures should be produced with the use of a drawing program such as ChemDraw. Structure drawing preferences (preset in the ACS Stylesheet in ChemDraw) are as follows:

1. As drawing settings select :
chain angle 120º
bond spacing 18% of width
fixed length 14.4 pt (0.508 cm, 0.2 in.)
bold width 2.0 pt (0.071 cm, 0.0278 in.)
line width 0.6 pt (0.021 cm, 0.0084 in.)
margin width 1.6 pt (0.056 cm, 0.0222 in.)
hash spacing 2.5 pt (0.088 cm, 0.0347 in.)
2. As text settings select:
font Arial/Helvetica
size 10 pt
3. Under the preferences choose:
units points
tolerances 5 pixels

4. Under page setup choose:

Paper A4 or Letter


5. Using the ChemDraw ruler or appropriate margin settings, create structure blocks, schemes, and equations having maximum widths of 11.3 cm (one-column format) or 23.6 cm (two-column format). Note: if the foregoing preferences are selected as cm values, the ChemDraw ruler is calibrated in cm.
6. Embolden compound numbers, but not atom labels or captions.

(n) Nomenclature. It is the responsibility of the authors to provide correct nomenclature. All nomenclature must be consistent and unambiguous and should conform to current American usage. Insofar as possible, authors should use systematic names similar to those used by Chemical Abstracts Service, the International Union of Pure and Applied Chemistry, and the International Union of Biochemistry and Molecular Biology.

The chemical names for drugs should be used. If the terminology is unwieldy, nonproprietary names of drugs may be used throughout the manuscript after the first mention and identification. Formally adopted nonproprietary names listed in United States Adopted Names (USAN) should be used. In cases in which a name has not been assigned by USAN, the International Nonproprietary Names (INN), approved by the World Health Organization, should be used. Trade names and laboratory codes should not be used except as additional information.


6. Proofs and Reprint

Proofs are sent to the author who submitted the papers. Authors are directed via email to download proofs from a secure FTP site unless authors request otherwise. Proofs should be verified against the manuscript and appropriate corrections made. Substantial changes in a manuscript after type has been set require editorial approval and in some cases may be cause for re-reviewing. An order form for reprints will be sent with the proofs. Please return the reprint order form, along with a purchase order or check, reprints will be shipped within 2 weeks after the printed journal date.

7. Corrections
