Reviewer 2 Report

I believe that it would be easier to follow the results, if instead of the chromatograms (they can be relocated in the appendices) there was a table with the identified compounds. At this moment the results part looks like a count of the identified compounds, combined with an evaluation of the spectral behavior for some of them.

In the case of discussions, a formulation of a vegetable product (parts of the plant) with different therapeutic uses would be useful. The analytical part is complex, therefore a more detailed interpretation of the obtained results would be useful.

Rows 215-219, respectively 234-238 are identical. In table 1, the use of the measurement unit after each retention time is redundant. Authors should include it in the head of the table.

In line 50, 55, Dracocephalum should be written in italics. In row 50 is preferable, for a better understanding of the text, replacing the digit 4 with text (four). In the case of the mass detector, it is correctly written with capital letters Q-TOF (row 55).

The article needs extensive English editing, which makes it difficult to read.

Round 2

Reviewer 2 Report

Dear authors,

I don't think that the information in your study should be duplicated. Table 1 in the Appendix fully reproduces Table 1 from the main text. Under these conditions, I consider that the information in Table 1 should possibly be centralized in a simplified manner, or exemplified by the classes of compounds described in the text, with the primary substances.

I think the header row from the tables should be repeated on each page to make it easier to follow the spectral parameters.

Otherwise, your material is valuable and suitable for publication.

Dear Reviewer.

I have corrected all the errors and inaccuracies that you pointed out. Indeed, the tables repeated each other, I modified the first table and it is of a brief informative nature, and the large table remained, as it was in the Appendix.

Thank you very much for your work and your valuable time.
