Special Issue Information

Dear Colleagues,

Herbs and spices play an important role in diets, beverages, medicines, and cosmetics. Their flavour and health benefits could contribute to the rapid growth of world trade. However, these food items may be contaminated by a wide variety of pathogenic microorganisms, mycotoxins, or pesticides. Cereal fungal contamination causes both economic and human health problems, by reducing the quantity and quality of the final product. In addition, the overuse of synthetic herbicides in order to improve the productivity of crops worldwide is environmentally hazardous and may cause the emergence of resistant weeds. Among the natural compounds, the essential oils have displayed a wide range of promising biological activities, such as herbicides, fungicides, larvicides, or insecticides with application in different industries. Their aroma and biological activity are closely related to their chemical composition and, at the same time, these mixtures of natural compounds can be useful biomarkers for the quality control of herbs, spices, and stored products.

This Special Issue compiles original research and critical reviews on the chemical composition and bioactivity of essential oils to control crop pests, increasing the shelf-life of harvest and post-harvest products.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs).

Safranal, the main volatile chemical of Saffron (Crocus sativus) was studied to estimate its allelopathic effects on the photosynthetic pigment chlorophyll, leaf electrolyte leakage, fresh weight, catalase (CAT), and peroxidase (POX) activity of the test plant Lettuce (Lactuca sativa). In this study, the effective concentration (EC50) of safranal on CAT was estimated to be 6.12 µg/cm3. CAT activity was inhibited in a dose-dependent manner by the increase in the safranal concentration while POX activity was increased. Moreover, Safranal caused significant physiological changes in chlorophyll content, leaf electrolyte leakage, and fresh weight of several weed species with Lolium multiflorum being the most sensitive. Furthermore, 5 µM Safranal showed significant inhibitory activity against dicotyledonous in comparison to the monocotyledons under greenhouse conditions. The inhibition of the CAT by safranal was similar to those of uncompetitive inhibitors, and therefore the decline in carbon fixation by plants might be the mechanism behind the inhibitory activity of safranal.
