“…The moisture of the studied honey samples was within the standards (not more than 20%) (Codex Alimentarius Commission, 2001; European Community, 2004), except the Ziziphus honey (S10) with a moisture values of 20.2%. This value is similar to the Moroccan Ziziphus honey (Aazza, Lyoussi, Antunes, & Miguel, 2014) and higher than the Sudanese and Algerian Ziziphus honeys (Idris, Mariod, & Hamad, 2011; Zerrouk, Seijo, Escuredo, & Rodríguez‐Flores, 2018), which explain the governance of the environmental conditions on determining this parameter. 16.9% was the minimum value, seen in the case the sample S4.…”

Physicochemical characteristics, main minerals, and antioxidant activity were determined for Palestinian honey samples belonging to different floral and geographical origins. The features of the analyzed samples were within the established international standards for honey quality control. One clear exception was the hydroxymethylfurfural (HMF) of the Ziziphus sample purchased from the Jericho region, which is the lowest city in the word characterized by a hot desert climate. The observed HMF value was 81.86 ± 2.64 mg/kg being two folds the maximum allowed in honey samples (40 mg/kg). As a second objective of the present work, the parameters were divided into two groups with different discriminatory power. The assessed physicochemical parameters, and the antioxidant activities, specific to the botanical origin discrimination, were used to run the first PCA. A strong correlation could be seen between the bioactive compounds and the antioxidant activities despite the geographical origin of the samples. Thyme and Ziziphus samples were the best samples, while citrus sample presented the lowest activity. Regarding the geographical discrimination, Ash and mineral contents in addition to the electrical conductivity were used. The output PCA conserved high represent ability of the data in the two‐first components being 82.72% and 9.60%. A little discrimination between the samples produced in the north and those produced in the south of the country, but it was not perfect. The intervention of the botanical variability could be the reason.

“…This indicates that gelam honey has high antioxidant activity. The variations in the IC 50 values of the honeys might be due to the differences in the phenolic contents and different types of phenolic compounds present [15] since each phenolic acid has different scavenging activity. [73,77] All tested stingless bee honeys showed IC 50 values lower than those of Apis mellifera honey (83.28 mg/mL) except for the acacia honey (97.24 mg/mL) from Geniotrigona thoracica and the starfruit honeys from both species.…”

“…Thus, the antioxidant capacity in honey is attributed to the synergistic effect of a wide range of compounds including phenolics, flavonoids, products of the Maillard reaction, enzymes, organic acids and other minor compounds. [15] The antioxidant activity of honeys has been reported to have a correlation with phenolics, flavonoids, products of the Maillard reaction, ascorbic acid, organic acids, enzymes, carotenoids, amino acids, proteins and mineral content. [16][17][18] Honey has often been reported to have potential antioxidant activity, which is beneficial for human health.…”

The physicochemical characteristics, antioxidant properties and botanical discrimination according to the organic acid content in Malaysian stingless bee honey were investigated. The results showed that the botanical origin and bee species significantly influenced the physicochemical characteristics and antioxidant properties of stingless bee honey. Principle component analysis (PCA) revealed that stingless bee honey was differentiable from Apis mellifera honey by acetic, citric, D-malic and tartaric. Starfruit could be distinguished from gelam and acacia honeys by lactic. Whereas the gluconic and succinic acids were confirmed as a marker to discriminate honey samples from Heterotrigona itama and Geniotrigona thoracica species. ARTICLE HISTORY

Earlier reports also revealed that TPC of tartary buckwheat was much higher than that of cranberry, apple, 26 raspberry, 27 honey, 28 corn, wheat, oats and rice 29 suggesting that tartary buckwheat may serve as an excellent dietary source of phenolics. Earlier studies have also reported that the TPC and TFC of the plants are influenced by environmental factors as well as the type of species.…”

Background: Buckwheat in the past had been the staple food for many regions in the Himalaya's and its utilization has declined with time. In recent times buckwheat gained a lot of attention as it has been placed in the list of underutilized crops by FAO. There is a strong sentiment and realization for buckwheat revival because of its nutraceutrical properties due to which it provides the consumers with extra choice for his food basket. In this context the present investigation aimed to evaluate the antioxidant potential and mineral element analysis of two buckwheat species grown in Kashmir region. Methods: To achieve this goal, antioxidant potential of two buckwheat species was done by using standard protocols. For ionomic analysis, atomic absorption spectrophotometry (AAS) was done to unravel the macro-and micro-nutrient composition. Result: Aqueous extract of Fagopyrum tataricum exhibits higher TPC (159.51±10.3 mg gallic acid equivalent g -1 DW) and TFC (79.49±9.76 mg rutin equivalent g -1 DW). The F. tataricum samples exhibit high radical scavenging activity (RS a50 =26.67µg ml -1 ) as compared to F. kashmirianum (RS a50 =34.15µg ml -1 ). Elemental analysis revealed that calcium (Ca) was found high in F. tataricum (5125±56.76ppm) while as the iron (Fe) and zinc (Zn) were found in high concentration in F. kashmirianum (1122.5±25.77ppm) and (122.75±12.34ppm) respectively. Conclusion: These findings suggested that buckwheat extract possess excellent antioxidant property and is rich source of minerals indispensable for human health. Thus, buckwheat could be a promising alternative in functional food sector for improving the social well-being and diminishing malnutrition especially for the impoverished community.
