Abstract
Background
Medicago species (Fabaceae) have garnered significant interest due to their rich array of natural phytochemicals, i.e. saponins, phenolics, and tannins, which exhibit a diverse range of medicinal and biological properties, including the ability to lower blood sugar and fat levels, as well as possessing antimicrobial, antioxidant, and anticancer effects. This study investigated various agro-morphological yield-attributed traits, essential oil characteristics, content of pigments, total triterpene saponins, condensed tannin, total phenolic, and total flavonoids, and biological activity of the three cultivated populations of six Medicago species collected across Iran.
Results
The highest fresh (1044.15 ± 5.35–1153.38 ± 2.61 g/m2) and dry (199.60 ± 1.71–274.48 ± 2.24 g/m2) weight and leaf area index (4.61 ± 0.21–5.83 ± 0.52) were measured in the cultivated populations of M. sativa. The essential oil content ranged from 0.02% to 0.17% (w/w) among the studied samples. A total of 26 chemical compounds 96.08‒99.90% of the essential oils were identified. n-Nonanal (52.21‒66.50%), dimethoxy-(E)-citral (5.22‒7.93%), terpinen-4-ol (1.55‒6.98%), citronellol (4.13‒6.78%), and α-terpineol (2.13‒4.89%) were the major components. Positive and negative significant correlation of antioxidant activity (DPPH and FRAP) (p < 0.01) with total anthocyanin (r = –0.57, r = 0.72), triterpene saponin (r = –0.75, r = 0.81), total phenolic (r = –0.90, r = 0.97), and total flavonoid content (r = –0.87, r = 0.86) were obtained. The highest antibacterial and antifungal activities of the EOs were obtained against Staphylococcus aureus (MIC: 0.062 mg/ml) and Candida glabrata (MIC: < 0.016 mg/ml), respectively. The results demonstrated the superior growth characteristics, valuable phytochemical compositions, and strong biological activities of the studied cultivated populations of Medicago.
Conclusions
In general, populations of M. phrygia, M. monspeliaca, and M. sativa are distinguished as promising candidates for further exploitation in breeding and production programs aimed at improving both agricultural productivity and pharmaceutical applications, as well as exploring innovative applications in food safety and pest management.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
