“…As shown in the table, the average flavonoid content of crude propolis obtained from Cibodas (14.8 AE 6.2 mg/g qE) is higher than that from Cileunyi Wetan (11.4 AE 4.4 mg/g qE). These values are higher than the flavonoid content of propolis reported by Salatnaya (2012) of 2.9 mg/g qE, but lower than the values reported by Tagliacollo and Orsi (2011) and Bridi et al (2015), which were 23.3 AE 6.0 mg/g qE and 78.0 AE 1.0 mg/g qE, respectively. Nevertheless, the flavonoid content of crude propolis that was determined in this study meets the standard flavonoid content of crude propolis in Brazil, namely 5 mg/g qE (Tagliacollo and Orsi, 2011).…”

Propolis and honey produced by stingless bees are regarded as high economic value products due to their bioactive components, which are significantly influenced by conditions at the cultivation location. This study investigated the effect of cultivation location on the amount and quality of propolis and honey produced by Tetragonula laeviceps cultivated in Modular Tetragonula Hives. Fifteen bee colonies were cultivated for at least three months in coffee plantations at two different locations, namely Cibodas and Cileunyi Wetan, Indonesia. The propolis was harvested from the hives and then evaluated to compare product quality from each location. The average production of propolis in both locations was found to lie in the range of 4.26-4.54 g/colony/month with a flavonoid content of 11.4-14.8 mg/g qE. Meanwhile, the average production of honey in both locations after eight months of cultivation was found to lie in the range of 0.93-1.44 g/colony/month. The vitamin C content of the honey obtained from both locations was 17.2-69.5 mg/100 g with an IC 50 of 1188-1341 mg/L, in terms of its ability to inhibit the free radical 2,2-diphenyl-2-picrylhydrazyl. This study shows that cultivation of stingless bees on a coffee plantation in the studied locations has the potential to provide sustainable production of propolis and honey from T. laeviceps.

“…Pinocembrin, pinobanksin, and chrysin are the characteristic lavonoids of propolis and these lavonoids have been found in European [19,21] and Chilean honey samples [22]. Small amounts of propolis might be incorporated into honey; therefore, propolis lavonoids might contribute to the phenolic composition of honey.…”

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.

“…The antioxidant and antimicrobial activities of Chilean honey have been studied over the last few years. These properties have been mainly attributed to the phenolic compounds present in the samples (Bridi et al, 2015;Giordano et al, 2018;Montenegro et al, 2013). However, these honey samples not included the polyphenolic profile of several Ulmo honey samples and its relation with the antibacterial activity.…”

Monofloral Ulmo honey is a very appreciated product in the international market but more information is needed in order to support their health properties. Total phenolic and flavonoid contents, antioxidant capacity and antibacterial activity of monofloral Ulmo (Eucryphia cordifolia) honey samples were determined. The samples contained between 176 and 208 mg gallic acid eq (GAE)/100 g for total phenolic content (TPC) and 43-90 mg Quercetin eq/100 g for total flavonoid content (TFC). The antioxidant activity ranged between 91 and 152 mM eq Trolox/g and 28-49 mM eq Trolox/g for DPPH and ABTS assays, respectively. All phenolic extracts from honey samples inhibited Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa and Escherichia coli by plate assays. The chromatographic profile showed that Ulmo honey contained the polyphenolic gallic, caffeic, and coumaric acids, the flavonoids pinocembrin, chrysin, quercetin, luteolin and apigenin, and abscisic acid. Compuestos bioactivos y propiedades antibacterianas de la miel monofloral de Ulmo RESUMEN La miel monofloral de Ulmo es un producto muy apreciado en el mercado internacional, pero se necesita más información para respaldar sus propiedades saludables. Se determinaron los contenidos fenólicos y flavonoides totales, la capacidad antioxidante y la actividad antibacteriana de muestras de miel monofloral de Ulmo (Eucryphia cordifolia). Las muestras contenían entre 176-208 mg eq de ácido gálico (GAE)/100 g para el contenido fenólico total (TPC) y 43-90 mg eq de quercetina/100 g para el contenido total de flavonoides (TFC). La capacidad antioxidante osciló entre 91-152 mM eq Trolox/g y 28-49 mM eq Trolox/g, para los ensayos de DPPH y ABTS, respectivamente. Todos los extractos fenólicos de muestras de miel de ulmo inhibieron Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa y Escherichia coli mediante ensayos en placa. El perfil cromatográfico mostró que la miel de ulmo contenía como compuestos bioactivos los ácidos, gálico, cafeico y cumárico, los flavonoides pinocembrina, crisina, quercetina, luteolina y apigenina, y ácido abscísico.
