An Insight into Cuscuta campestris as a Medicinal Plant: Phytochemical Variation of Cuscuta campestris with Various Host Plants
Round 1
Reviewer 1 Report
1. Because there are no real interaction issues in this study, “Interaction” in the title is inappropriate. “ change” or “alternation” may be better.
2. For all figures, there are no error bars for each group (n=3), why?
3. Please explain what are the “standard extracts”.
4. For the biomass, the study only provides the weight of one-thousand seeds, which only investigates the quality of the seeds. I suggest that the total biomass of the seed is also needed to show the effect of the host on seed production.
5. The compound profiles in this manuscript are quite different from that are published in the literature. I wonder if the seed (identification number 2432/88) really is Cuscuta campestris.
6. The descriptions in Lines 282-288 are very unclear, please revised.
7. The description in Line 300 is unclear, please revised.
8. In Line 374, the lowest is usually only one, please describe clearly.
9. In line 282, “soecies” is a typo.

- References revised according to the editor comment.
- Because there are no real interaction issues in this study, “Interaction” in the title is inappropriate. “ change” or “alternation” may be better.
Authors' comment: title was modified.
- For all figures, there are no error bars for each group (n=3), why?
Authors' comment: error bars were added in the text.
- Please explain what are the “standard extracts”.
Authors' comment: All HPLC grade standards were provided from Sigma Aldrich Co. (St. Louis, MO, USA). The measurements were made by comparing the retention time of the samples with the standard (Sigma-Aldrich), which is explained in the Materials section (2. Material and methods).
- For the biomass, the study only provides the weight of one-thousand seeds, which only investigates the quality of the seeds. I suggest that the total biomass of the seed is also needed to show the effect of the host on seed production.
Authors' comment: Due to the differences in the size and planting density of the host plants, the seed yield was not considered an accurate trait.
- The compound profiles in this manuscript are quite different from that are published in the literature. I wonder if the seed (identification number 2432/88) really is Cuscuta campestris.
Authors' comment: In other literature, metabolites have been evaluated in organs such as shoots, haustoria and flowers. The growth climate and the type of hosts also make a big difference in the amount of its metabolites. The seeds of this plant were collected by botanists at the university of Zabol and are kept in the seed bank of the university.
- The descriptions in Lines 282-288 are very unclear, please revised.
Authors' comment: It was modified.
- The description in Line 300 is unclear, please revised.
Authors' comment: It was modified.
- In Line 374, the lowest is usually only one, please describe clearly.
Authors' comment: It was corrected.
- In line 282, “soecies” is a typo.
Authors' comment: Corrected
Reviewer 2 Report
Review of the manuscript 2248185
The authors of the manuscript made an attempt to evaluate the effect of host species on the health-promoting compounds found in field dodder seeds. The paper presents quite interesting results. The objective of the study should be reformulated. The title should be more precise. The rest of the manuscript needs some changes as well. English linguistic correction should be made. Therefore I recommend major revision of the manuscript.
More detailed comments are given below:
Line 15 – Cuscuta, not Cascuta
line 29 – one dot should be deleted
line 83 – tomato, not Tomato
line 94-97 – The aim of the study should be reformulated. The authors haven’t studied the bioactive effect of secondary metabolites of dodder seeds. Fragments “pay attention to the effect of the host on chemical profile” and “ to evaluate the effect of host species on the health-promoting compounds found in field dodder seeds” provide the same information, it should be shortened.
Line 105 – seeds of what species have the number 2432/88? Of dodder? It should be precised.
line 107 – is the pot size in cm? The information should be added.
There are Figure 2, 4 and 6 inserted into Materials and methods section. They are present in the text before Figures 1 and 3… Figures should be consecutively numbered.
line 232 – letters indicate significance of differences, not significance of results
line 236 – “The effect of host plant on seed weight” – it seems that a fragment of this sentence is missing
line 248 250 – this phrase should be deleted, it repeats the information given in the materials and methods
line 259 – 262 - the description of the Figure 3 D is not precise enough from the statistical point of view. Please check also the description of other figures, especially when letters indicating significance of differences of means are like “ab”, “bc” and not a, b, c.
Standard error bars should be added to figures 1, 3, 5.
References to figures should be deleted in the discussion section.

Round 2
Reviewer 1 Report
In the article, there are many "the highest" and "the lowest", however, they should indicate always only one, it can not be two or three. Please describe clearly.

Reviewer 2 Report
The manuscript has been substantially improved by the authors. Most corrections has been made. I have only one remark on the misunderstanding concerning description of results. The authors has changed figure captions, however my intention was to change description of figures in the text (in the section „results”). Figure captions were better in the first version of the manuscript.
I’m explaining on the example of Figure 5D:
The authors write: „The antioxidant activity of extracts prepared from seeds of dodder developed on different hosts showed that DPPH radical scavenging was higher in seed extracts developed on thyme and onion hosts, respectively, and the lowest DPPH radical scavenging occurred with extracts of alfalfa-hosted plants (Figure5D).” The description of the Figure 5D is not precise enough from the statistical point of view. DPPH radical scavenging in alfalfa-hosted plants was significantly lower than in basil, onion and thyme but difference between alfalfa and tomato-hosted plants wasn’t significant.
Please check and correct the description of results in the text (my remark concerns Figures 5, 6 and 7 where differences are not as clear to be marked by single letters a, b or c).
