“…Annual species such as Medicago sativa and Trifolium repens had secondary and minor importance (3-15%) in most analyzed multifloral honeys. This result can be explained by fact that these high nectar-producing annual species share the same flowering period with Q. saponaria and R. trinervia, two dominant woody native species in the study area (Montenegro et al, 2008).…”

“…A total of 33 different pollen grain types were found in the honey samples. Three main unifloral honeys (pollen frequency > 45%) belonging to a single plant species according to Montenegro et al (2008) could be described for the study samples: G. officinalis (14 samples), Q. saponaria (18 samples), and R. trinervia (7 samples) ( Table 1). Multifloral honeys (pollen frequencies in the range of 15-45%) were also identified by melissopalynological analysis, with G. officinalis (7 samples), Q. saponaria (2 samples), and R. trinervia (4 samples) again being the most common.…”

The color of honey has special relevance in the international market, as different markets demand specific colors of honey. Chile has very diverse native and exotic flora, which are used by bees (Apis mellifera) to produce a range of honey types, including honeys of different colors. In this context, determining the relationships between color and botanical origin among Chilean honeys is very relevant. The objectives of the present study were to compare three methodologies for determining color in Chilean honeys (Pantone®, optical density (OD), and Pfund) and to define the relationship between color and botanical origin of the characterized honeys. The most common honeys from the Libertador Bernardo O'Higgins Region (VI Region) of Chile were Galega officinalis, Quillaja saponaria, and Retanilla trinervia unifloral honeys, all of which have lighter colors than internationally described. Both the OD and Pfund methods could identify significant differences between dominant species; specifically, these methods were able to discriminate between G. officinalis and Q. saponaria honeys and between G. officinalis and R. trinervia honeys. The OD and Pfund methods revealed that honeys of G. officinalis (A530 nm: 0.93 and 95.53 mm Pfund) were darker than those of Q. saponaria (A530 nm: 0.42 and 80.66 mm Pfund) and R. trinervia (A530 nm: 0.35 and 73.41 mm Pfund). Although the three methods for determining the color of Chilean honeys had different efficacies, the OD method was able to discriminate among dominant species and honey types. Significant correlations among the dominant species were found for Chilean honeys from the Libertador Bernardo O'Higgins Region using both the OD and Pfund methods.

“…Characteristic matorral species include Baccharis concave (chilca), Peumus boldus (boldo), Lithraea caustica (litre), Trevoa trinervis (tevo), and Q. saponaria (soapbark tree). The central zone is characterized by the production of endemic monoloral honey from the quillay (Q. saponaria) and corontillo (Escallonia pulverulenta) species, while the southern zone, characterized by temperate forests, is characterized by native uniloral honey made from avellano (Gevuina avellana), ulmo (E. cordifolia), and tineo (Weinmannia trichosperma) [2].…”

Honey chemical composition is related to the plant species where nectar is collected by honeybees. Chilean beekeeping is characterized by a variety of honey types, some unique, due to a high participation of endemic and native species. In Chile, the most emblematic lower honey, both for its abundance and sensory characteristics, is ulmo honey (Eucriphya cordifolia) and quillay honey (Quillaja saponaria). Melissopalynological analyses are used to establish whether a honey is uniloral, where at least 45% or more pollen grains found in it belong to the same species. The antioxidant and antimicrobial activities of Chilean honey have been studied in the last years with excellent results. Quillaja saponaria, Eucriphya cordifolia, Azara petiolaris, and Retanilla trinervia are within the Chilean endemic species that produce uniloral honeys that show antioxidant potential and antibacterial activity against pathogenic gram positive and gram -negative bacteria and also multiresistant strains. These activities are mainly atributed to the phenolic compounds such as lavonoids. Among these atractive characteristics of honey, it is important to note that this product has low toxicity and the medicinal properties of honey will help to protect honeybees by adding value not only to the signiicantly important process of pollinating crops and native plants, but also for the medicinal importance of their products.

“…Briefly, bee pollen (20 g) was placed on acetolyzed slides (Montenegro et al, 2008). Then, a sample aliquot was diluted with warm distilled water (20 mL at 40 °C), and the solution was transferred to an appropriate tube and centrifuged at 3,500 rpm for 10 min.…”

E. Mejías, C.J. Gómez, P. Gareil, N. Delaunay, and G. Montenegro. 2018. Characterization of phenolic profile alterations in metal-polluted bee pollen via capillary electrophoresis. Cien. Inv. Agr. 45(1): 51-63. Bee pollen is a conglomerate of plant pollens, and its nutritional contents include bioactive compounds with antioxidant/antiradical potentials. These potentials are conditioned by botanical origin. In Chile, the native flora is diverse and promising in terms of bioactive compounds, but many plants grow in metal-polluted areas. The associated bioaccumulation could negatively affect the antioxidant/antiradical abilities of bee pollen. To assess the relationship between the bioaccumulation of metals and the antioxidant activity of pollen, complete bee pollen was collected near and far from the Llaima Volcano, albeit in ranges that ensured the same botanical origins. Mellisopalynological analysis determined Escallonia rubra pollen was the most abundant native flora in complete bee pollen. Therefore, E. rubra pollen collected near and far from the Llaima Volcano was evaluated for the following: phenolic compounds via colorimetric assays; antioxidant activity via ferric reducing/antioxidant power assays; antiradical activity via 1,1-diphenyl-2-picrylhydrazyl radical assays; and metal contents via inductively coupled plasma optical emission spectrometry. Llaima samples had higher Cu and Fe but lower Mn contents and lower antioxidant and antiradical capacities than did the control samples. These results were supported by subsequent fortification assays in Llaima E. rubra samples. In fortified samples with significantly higher metal contents, antiradical and antioxidant abilities decreased. Moreover, shifts in migration times were found for naringenin, rutine, and caffeic acid after capillary electrophoresis (CE) analysis in fortified samples. In conclusion, the results indicated an inverse correlation between metal contents and antioxidant/ antiradical potentials in bee pollen.
