“…Larrea samples were identified by leaf epidermal segments characterized by epidermal cells with straight anticlinal walls, cyclocytic and anomocytic stoma (20.54 ± 3.25 µm long and 27.80 ± 4.55 µm lat) (Figure 5A), abundant unicellular trichomes with acute apex (234.45 ± 145.55 µm long) with the epidermal cells arranged in groups of 4 to 6 converging toward the base of the trichome (Figure 5B), features previously described for these species by Mercado et al. (2018).…”

“…For botanical analysis, samples of each raw propolis (0.5 g) were processed according to Salas, Mercado, Zampini, Ponessa, and Isla (2016). Botanical identification was made by comparing observed structures with both plant materials of Z. punctata , L. divaricata , and L. cuneifolia collected at the site where the beehives were located and with relevant literature (Álvarez et al., 2012; Lersten & Curtis, 1996; Mercado et al., 2013, 2018; Moreno et al., 2015).

The effect of Argentine propolis extracts against enzymes related to metabolic syndrome and oxidative stress, as well as the botanical origin of raw propolis, were studied. Histological and chemical analyses of propolis samples revealed that the botanical origin is Zuccagnia punctata, an Argentine medicinal plant. The melissopalynological analysis showed both pollen grains of Z. punctata and the other plant species. This result indicates that the differences found in the botanical remains compared to the palynological studies may have been caused by the bees selecting resinous shrubs mainly of Z. punctata for the production of propolis and other plants with flowers for the production of honey. The richness of propolis was remarkable in two flavonoid precursors (2´,4´‐dihydroxy‐3´‐methoxychalcone, 2´,4´‐dihydroxychalcone), the major chemical components of Z. punctata. The hydroalcoholic extracts of Argentine propolis and Z. punctata were able to inhibit enzymes associated with the metabolic syndrome, including α‐glucosidase, α‐amylase and lipase, with IC50 values between 7 to 14, 37 to 48, and 13 to 28 µg/mL, respectively. Biological activity was mainly attributed to chalcones. Oxygen and nitrogen reactive species scavenging activity was determined by the assays of superoxide radical (O2•−), hydroxyl radical (HO•), hydrogen peroxide (H2O2), nitric oxide (NO•), and cation radical (ABTS•+). Results showed SC50 values between 115 to 278, 12.50 to 46; 39 to 92; 50 to 104.50 and 23 to 33.75 µg/mL, respectively. This study suggests for the first time that propolis from Argentina is highly effective in inhibiting enzymes related to the metabolic syndrome and in free‐radical scavenging that would justify its use as a dietary supplement or as a functional ingredient in special food. Practical Application Propolis from Catamarca, Argentina, is traditionally used as medicine and food. Its botanical origin is Zuccagnia punctata, an endemic plant species popularly used as a medicine in Argentina. Propolis has the ability to regulate the activity of enzymes involved in the carbohydrate and lipid metabolism, and consequently in metabolic syndrome. Besides, its antioxidant capacity makes it a natural product that can be used as a dietary supplement or as a functional ingredient in special foods. It is important to highlight that in the Argentine Food Code, propolis was incorporated in 2008 as a dietary supplement and the present results give major added value to this product.

“…The species Larrea nitida and Baccharis are sources of propolis from the Andean region [ 55 , 56 ] and Zuccagnia punctata is a source of propolis from the Monte ecoregion in northwestern Argentina [ 38 , 40 , 44 , 45 , 46 , 47 , 48 , 57 , 58 , 59 , 60 ]. The Argentine propolis has several functional properties such as antibacterial, antifungal, anti-inflammatory, antioxidant, nematicidic, and cytotoxic, among others, apart from being an inhibitor of enzymes linked to metabolic syndrome [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 61 , 62 , 63 , 64 ]. Based on their properties, several products have been developed to date for use in human and veterinary medicine and in the food industry.…”

“…Although Larrea leaves [ 56 ] were not found, pollen of different plants from the region was found, including pollen from Zuccagnia and Larrea [ 58 ]. To confirm the botanical origin of propolis samples coming from the ecoregion of Monte of Sierras and Bolsones, a chemical characterization by HPLC-DAD of resin extracts from three jarilla species ( Z. punctata, L. divaricata, and L. cuneifolia ) was carried out and compared with propolis extracts [ 40 , 57 , 58 ].…”

The aim of this review is to provide overall information on Argentine propolis and to shed light on its potential, especially the one from the Monte region so as to support future research in the field. Around 1999, the Argentine propolis began to be chemically and functionally characterized to give it greater added value. Because Argentina has a wide plant biodiversity, it is expected that its propolis will have various botanical origins, and consequently, a different chemical composition. To date, five types have been defined. Based on their functionality, several products have been developed for use in human and veterinary medicine and in animal and human food. Because the Argentine propolis with the greatest potential is that of the Monte eco-region, this review will describe the findings of the last 20 years on this propolis, its botanical source (Zuccagnia punctata Cav.), its chemical composition, and a description of markers of chemical quality (chalcones) and functionality. Propolis can regulate the activity of various pro-inflammatory enzymes and carbohydrate and lipid metabolism enzymes, as well as remove reactive oxygen and nitrogen species. Consequently, it can modulate metabolic syndrome and could be used as a functional ingredient in food. Furthermore, hydroalcoholic extracts can act against human and animal pathogenic bacteria and human yeast, and mycelial pathogenic fungi. The ability to stop the growth of post-harvest pathogenic bacteria and fungi was also demonstrated. For this reason, Argentine propolis are natural products capable of protecting crops and increasing the lifespan of harvested fruit and vegetables. Several reports indicate the potential of Argentine propolis to be used in innovative products to improve health, food preservation, and packaging. However, there is still much to learn about these natural products to make a wholesome use of them.
