“…An important subject of pectin research is to study the application of one extraction technique, as well as conducting a comparative study between two or more techniques used to isolate pectic polysaccharides from a plant source, together with an investigation on the changes of its physicochemical, thermal and rheological characteristics. The methods of pectin extraction reported in the literature include conventional acid extraction with a mineral or organic acid (mostly citric acid) (Colodel & De Oliveira Petkowicz, 2018;Patova et al, 2019), microwaveassisted extraction (Košťálová, Aguedo, & Hromádková, 2016;Maran & Prakash, 2015), ultrasound-assisted extraction (Hosseini, Khodaiyan, Kazemi, & Najari, 2019;Moorthy, Maran, Surya, Naganyashree, & Shivamathi, 2015), enzymatic extraction (Sabater et al, 2018;Wikiera, Mika, & Grabacka, 2015), subcritical water extraction (Liew, Teoh, Tan, Yusoff, & Ngoh, 2018;Muñoz-Almagro, Valadez-Carmona, Mendiola, Ibáñez, & Villamiel, 2019), and also combined techniques such as microwave heating extraction (Rodsamran & Sothornvit, 2019), ultrasoundmicrowave assisted extraction (Liew, Ngoh, Yusoff, & Teoh, 2016) and enzymatic-ultrasonic extraction (Yang, Wang, Hu, Xiao, & Wu, 2018). Some previously published studies have reported a comparison between techniques used for pectin extraction (Rodsamran & Sothornvit, 2019;Bagherian et al, 2011).…”

Physicochemical properties of pectin from Malus domestica ‘Fălticeni’ apple pomace as affected by non-conventional extraction techniques

2020

Six non-conventional techniques (microwave-assisted extraction -MAE, ultrasound-assisted extraction -UAE, enzyme-assisted extractionwith cellulase, EAE1, and Celluclast 1.5L, EAE2, ultrasound-assisted extractionheating treatment -UAEH, and enzyme-assisted extractionultrasound treatment -EAU) and conventional citric acid extraction -CE were applied to extract pectin from Malus domestica 'Fălticeni' apple pomace, and were compared in terms of extraction yield and physicochemical properties of pectin. MAE led to the highest extraction yield and ; the lowest pectin recovery was found for EAE2. Pectin samples obtained by MAE showed color parameters comparable to commercial apple (AP) and citrus (CP) pectin, and had high galacturonic acid content, increased equivalent weight and high degree of esterification. High galacturonic acid content and degree of esterification were also found in UAE pectin samples. On the opposite side, EAE1, EAE2 and EAU pectin had high equivalent 2 weight, but lower degree of esterification that classified EAE1 and EAU pectin as lowmethoxylated pectin. UAEH and MAE pectin showed thermal properties that were similar toto that of commercial AP and CP . The rheological characterization of pectin samples highlighted the high viscosities of UAE and MAE pectin solutions, which were positively correlated with their galacturonic acid content.

“…This plant is primitive and ancient and belongs to the Equisetaceae family from the Polypodiophyta division. It is a good source of natural compounds, including antioxidants [ 56 ], flavonoids [ 57 ], and biologically-active carbohydrates [ 58 ]. E. arvense is a model object to isolate for the structural analysis of key proteins involved in the plant metabolism, including ferredoxin I and II isoforms [ 59 ], and cytochrome c reductase [ 60 ].…”

We report the inhibitory effect of peptide extracts obtained from seven medicinal plants against a causative agent of late blight disease Phytophthora infestans. We find that all the extracts possess inhibitory activity toward the zoospores output, zoosporangium germination, and the development of P. infestans on potato disc tubers at different quantitative levels. Based on the biological effects detected, an extract of common horsetail (Equisetum arvense) biomass is recognized as the most effective and is selected for further structural analysis. We perform a combination of amino acid analysis and MALDI-TOF mass spectrometry, which reveal the presence of Asn/Asp- and Gln/Glu-rich short peptides with molecular masses in the range of 500–900 Da and not exceeding 1500 Da as the maximum. Analytical anion-exchange HPLC is successfully applied for separation of the peptide extract from common horsetail (E. arvense). We collect nine dominant components that are combined in two groups with differences in retention times. The N-terminal amino acid sequence of the prevalent compounds after analytical ion-exchange HPLC allows us to identify them as peptide fragments of functionally active proteins associated with photosynthesis, aquatic transport, and chitin binding. The anti-oomycete effects may be associated with the conversion of ribulose-1,5-bisphosphate carboxylase/oxygenase to produce a number of biologically active anionic peptides with possible regulatory functions. These data inform our knowledge regarding biologically active peptide fragments; they are the components of programmed or induced proteolysis of plant proteins and can realize secondary antimicrobial functions.
