Fruit characteristics, phytochemical and antioxidant properties of blueberry ash (Elaeocarpus reticulatus)

Abstract

Blueberry ash (Elaeocarpus reticulatus Sm.) fruit has potential for human nutrition, but there is limited information on this fruit. This preliminary study aimed to characterise blueberry ash fruit and examine the influence of extraction solvents on its phytochemical and antioxidant properties. Blueberry ash fruit is dark blue in colour and is a stone fruit of small size (7 mm) and light weight (0.2 g). However, it has a high portion of flesh (60% of fruit weight), which is edible and can be a potential source of phytochemicals. Water, ethanol, acetonitrile, acetone, and their combination were tested for extraction of phytochemicals from flesh of this fruit. Water or absolute organic solvent was ineffective for extraction of phenolic compounds from this fruit, but mixtures of water and organic solvents were more effective, and 50% acetone was the most suitable extraction solvent. Extraction with 50% acetone, this fruit was found to contain high levels of total phenolic content, flavonoids, proanthocyanidins, and anthocyanins (104 mg GAE/g, 155 mg RUE/g, 78 mg CE/g, and 119 mg CGE/g, respectively). In addition, this fruit was found to possess potent antioxidant properties. Therefore, this fruit should be further studied for identification of its phenolic compounds and further tested for their biological properties.

Phytochemical Screening, Antioxidant, Antidiabetic and Anticancer Activities of Elaeocarpus variabilis Fruit

“…These findings recommend 85% of the antioxidant capacity of E. ganitrusis by flavonoid components (Bharti, 2013). The organic solvents had been a significant presence of higher levels of total phenolic, flavonoid, and Proanthocyanidins (Vuong et al, 2018). Similarly seed was showed high level of Phenolic and flavonoid (Bhatt and Dahal, 2019).…”

Impact of Various Essential Oils and Plant Extracts on the Characterization of the Composite Seaweed Hydrocolloid and Gac Pulp (Momordica cochinchinensis) Edible Film

“…Mature Gac fruit samples were selected from central markets in Khanh Hoa province, Vietnam. After cleaning, the pulp was separated, sliced, and freeze-dried using an industrial freeze-dryer model LyoBeta 35 (Telstar Technologies, Valencia, Spain) for 24 h. Lemon myrtle extract, blueberry ash fruit extract, and macadamia peel extract were prepared according to the methods described by Saifullah, McCullum, McCluskey and Vuong [30], Vuong, Ngoc Thuy Pham, Vu, Dang, Van Ngo and Chalmers [31] and Dailey and Vuong [32].…”

Phytochemical Screening and Comparative Antioxidant Potential of Different Extracts Isolated From E. Ganitrus Leaves

“…Acetone extract of this fruit contains high levels of total phenolic content (104 mg GAE/g) and flavonoid (155 mg RUE/g). The free radical scavenging efficiency of E. recurvatus bark extract was reported (Kumar et al, 2007;Lakshmiet al, 2016;Vuong et al, 2018;Sharma et al, 2021).…”
