“…Forage plants represent a rich and interesting source of bioactive compounds that are specific to each forage species [ 41 ]. However, when considering the common individual phenolic compounds, namely, chlorogenic and cryptochlorogenic acids, hydroxycinnamic acid derivatives, and quercetin 3-glucoside ( Table 6 and Table 7 ), our findings indicate that their contents widely differed according to species and growth stages.…”

Mediterranean pasture and forage legumes are important components of sustainable production systems. Subterranean clover and sulla represent key species having proven high agronomic value and traits for production and multiple services. Our research investigated the potential of the abovementioned species as a source of phenolic compounds and antioxidants for contributing to support their full exploitation in the fodder, animal welfare, and nutraceutical sectors. Antioxidant capacity, as well as the content of total phenolic compounds and individual phenolic compounds, was determined in subterranean clover and sulla shoots at the vegetative, flower bud, flowering, and seed ripening phenological stages. The antioxidant capacity and the phenolic content were affected significantly by harvest time. In subterranean clover, 10 individual phenolic compounds were detected, and isoflavones were the most abundant (3.19–18.27 mg·g−1 DM). Eleven phenolic compounds were identified in sulla shoots, and chlorogenic acid (0.76–3.43 mg·g−1 DM) and diosmin (3.64–4.94 mg·g−1 DM) were the most represented compounds at the vegetative and flower bud stage. On the basis of our findings, a complementary utilization of both legume species is suggested; this might ensure the exploitation of all phenolic compounds in view of the potential benefits for animal production and health.

“…In agreement with data previously reported for the composition of H. coronarium collected in Southern Italy [ 25 ], the tannins identified in the plant material used in this study are condensed tannins of the prodelphinidin type, with catechin as the dominant unit, and gallocatechin and epigallocatechin as the dominant extender units. Due to the high number of hydroxyl groups in their structure, these specialized metabolites have a great ability to complex with proteins, and possibly to exert a defence strategy against pathogens [ 13 , 42 , 43 , 44 ].…”

“…The literature data indicate that plants from the Leguminosae family can also represent a potential source of new nematicidal products, due to their content of bioactive compounds such as saponins, polyphenols and alkaloids [ 13 , 14 , 15 ]. In previous investigations, saponin fractions from various Medicago species were found to be strongly active on the infective juveniles ( J2 ) of the RKN Meloidogyne incognita Kofoid et White (Chitw.…”

“…According to the literature data, the chemical composition of H. coronarium is characterized by a high content of condensed tannins (proanthocyanidins), flavonoids and saponins [ 25 , 26 ]. All of these phytochemicals are known for a number of biological and pharmacological effects [ 13 ], among which is their nematicidal activity [ 17 , 27 , 28 ]. Soyasaponin I, i.e., the main saponin constituent of H. coronarium [ 25 ], was stated to have only a moderate biocidal activity on the grapevine nematode X. index [ 18 ].…”

The content of nematicidal metabolites such as saponins, flavonoids and tannins in sulla (Hedysarum coronarium L.) suggests its potential nematicidal activity. In this study, the biocidal activity of 62.5–1000 μg mL−1 concentrations of flavonoid and tannin fractions from sulla was assessed in in vitro assays on the infective juveniles (J2) of the root-knot nematode (RKN) Meloidogyne incognita, while the suppressive effects of soil amendments with 10–40 g kg−1 soil rates of sulla biomass were investigated on potted tomato infested by M. incognita. The content of total nitrogen, carbon, flavonoids, tannins and saponins of sulla experimental material was also determined. After a 96-h exposure, more than 80% of the M. incognita J2 were killed even by a 125 µg mL−1 concentration of the flavonoid extract, while mortality peaked at 89% only at the 1000 µg mL−1 concentration of the tannin solution. Soil incorporation with sulla biomass significantly reduced the M. incognita densities both on tomato roots and in the soil, compared to either the non-treated control and chemical treatment with Fluopyram. The data confirmed the nematicidal potential of sulla, mainly due to its content of flavonoids and tannins, suggesting its suitability as green manure or a soil amendment for sustainable RKN management.

“…Forage plants are a rich source of biologically active metabolites that influence animal nutrition but also have a therapeutic potential in human health. Among them, the Fabaceae botanical family is the most important source of specialized metabolites with application in the pharmaceutical and agro-industry, The review paper by Tava et al ( 2021 ) describes the bioactive compounds, especially saponins and polyphenolics, isolated from representative legume forage plants ( Medicago , Trifolium , Onobychis , Melilotus , Hedysarum , Lotus , Trigonella and Bituminaria species) with particular emphasis on their qualitative and quantitative composition. In addition, the Authors highlight the main pharmacological effects discovered for triterpenic saponins from Medicago species (antimicrobial, neuroprotection, cytoxycity, stimulation of pancreatic lipase, etc.)…”
