Summary Biological properties of Moroccan propolis have been scarcely studied. In the present work, the total phenols and flavonoids from 21 samples of propolis collected in different places of Morocco or 3 supplied in the market were determined, as well as the in vitro capacity for inhibiting the activities of acetylcholinesterase, α‐glucosidase, α‐amylase, lipoxygenase, tyrosinase, xanthine oxidase and hyaluronidase. The results showed that samples 1 (region Fez‐Boulemane, Sefrou city) (IC50 = 0.065, 0.006, 0.020, 0.050, 0.014 mg mL−1) and 23 (marketed) (IC50 = 0.018, 0.002, 0.046, 0.037, 0.008 mg mL−1) had the best in vitro capacity for inhibiting the α‐amylase, α‐glucosidase, lipoxygenase, tyrosinase and xanthine oxidase activities, respectively. A negative correlation between IC50 values and concentration of phenols, flavones and flavanones was found. These activities corresponded to the generally higher amounts of phenols and flavonoids. In the same region, propolis samples have dissimilar phenol content and enzyme inhibitory activities.

We thank you for your e-mail of 24 July 2017 with the comments on our manuscript (MS) INDCRO-D-17-01815R2 on "Growth, photosynthetic pigments, phenols and in vitro biological activities of aqueous anise, dill and fennel extracts in response to 2 mM Zinc". We have read it carefully and we do understand most of the referee's comments. Please find bellow our reply and comments following each point raised by the reviewers. All corrections and additions performed in the MS text have been marked in blue. Reviewers' comments: Reviewer #1: The revised version of the manuscript INDCRO-D-17-01815R2 meets all the criteria of scientific work. Paper may be published after several technical corrections:-Suggestion for the title (please accept the proposal, the current version is incorrect): Growth, photosynthetic pigments, phenolic content and biological activities of Foeniculum vulgare Mill., Anethum graveolens L. and Pimpinella anisum L. (Apiaceae) in response to zinc RESPONSE:This proposal made by reviewer 1 was taken into account.

This review updates the information upon the chemical composition of propolis from all Mediterranean countries as well as their biological properties and applications. The non‐volatile fraction of propolis was characterized by the presence of phenolic acids and their esters and flavonoids. Nevertheless, in some countries, diterpenes were also present: Sicily (Italy), Croatia, Malta, Creta (Greece), Turkey, Cyprus, Egypt, Libya, Algeria and Morocco. The volatile fraction of propolis was characterized by the presence of benzoic acid and its esters, mono‐ and sesquiterpenes, being the oxygenated sesquiterpene β‐eudesmol characteristic of poplar propolis, whereas the hydrocarbon monoterpene α‐pinene has been related with the presence of conifers. Regardless the chemical composition, there are common biological properties attributed to propolis. Owing to these attributes, propolis has been target of study for applications in diverse areas, such as food, medicine and livestock.
