The Phythochemical Research of Armenian Apricot Gums (Gummi armeniacae)

Abstract

Aim:The plant derivative, the gum's exudates are of great interest among polysaccharides. Nowadays, it is of crucial importance to study the structural peculiarities and the conditioned biological activity of the Gummi Armenicae of native origin as an alternative version of the Gummi Arabicae. Materials and methods: As a material for research served the gum procured from Apricot trees (Armenian Vulgaris Lam.), cultivated in different regions of Armenia annually in spring during juice motion period in 2010-2014 years. The quantity of polysaccharides in gum was determined by the method of gravimetric balance after drying. The quantitative ratio of monosac charide in the examined polysaccharide complex was detected by the method of MRI. Results: By the methods of spectral analysis (PMR 1H and NMR 13C) the structure of Apricot gums polysaccharide fraction was detected. From the analysis of PMR 1H and NMR 13C spectra it is obvious that polysaccharide complex fraction is composed from the rest of α-L-arabionopyranose, β -L-arabionopyranose, α-D-galactopyranose, β -D-galactopyranose, α -D-glucopyranose, β -D-glucopyranose. Low molecular compounds in nonpolar fraction of apricot gum were determined by GC-MS method. The results show that in Rt1=22.5, Rt2=26.3, Rt3=31.4. Simple phenols were registered -peaks of catechols` hydroquinones, pyrogallols, amounts of which are respectively 7.58%, 4.27%, 5.69%.

Prunus armeniaca gum exudates: An overview on purification, structure, physicochemical properties, and applications

“…Since arabinose and galactose are the most abundant monosaccharides in the PAGE composition, it is suggested that this gum has an galactoarabinan-like structure. In a recent study, Babken et al (2018) used 1 H and 13 C NMR analyses to elucidate the structure of PAGE. They found that this gum is a complex polysaccharide composed of α and β-L-Arap, α and β-D-Galp and α and β-D-glucopyranoses (β-D-Glcp).…”

“…Accordingly, it is clear that phenolic compound present in PAGE is strongly involved in antioxidant activity as determined by DPPH assay. Babken et al (2018) determined the phenolic profile of PAGE using GC-MS analysis. It was found that PAGE had, on average, 7.58% catechols, 4.27% hydroquinones, and 5.69% pyrogallol.…”

“…Since the functional and physicochemical characteristics of the hydrocolloids are mainly dependent on their chemical composition as well as structural properties (Sherahi et al., 2017), it is necessary to determine the chemical composition and structural properties of the new source of hydrocolloids. Various studies have been conducted to characterize Prunus family gum exudates (PAGE) and evaluate its physicochemical, structural, and functional properties (Al‐idee et al., 2020; Alwaan & Mahdi, 2016; Azam Khan et al., 2012; Babken et al., 2018; Bouaziz et al., 2015; Chichoyan, 2015; Chichoyan & Shaboyan, 2016; Ding et al., 2019; Ergin et al., 2018; Fathi, Mohebbi, & Koocheki, 2016a, 2016b; Fathi et al., 2017; Hamdani et al., 2017, 2018; Hashemi & Raeisi, 2018; Islam et al., 2019; Jamila et al., 2020; Khorsha et al., 2016; Kora, 2018; Licá et al., 2018; Lluveras‐Tenorio et al., 2012; Molaei & Jahanbin, 2018; Najafi et al., 2020; Rahim et al., 2018; Shamsara et al., 2015, 2017; Shi et al., 2019; Stephen & Shirley, 1986; Theophil Anand et al., 2019; Wei, Zhang, He, et al., 2019; Wei, Zhang, Zhang, et al., 2019; Zhang et al., 2020). We tried to present a compressive review on the documents on PAGE to explore its potential application in food, textile, cosmetic, and pharmaceutical systems.…”
