“…[56] reported that the pentagalloyl glucoside from mango peels possessed potent scavenging effects on hydroxyl radicals, superoxide anions, and singlet oxygen. Namngam et al [57] isolated different phenolic fractions from kernels of ‘Kaew’ and ‘Choke-Anan’ cultivars from Thailand. They observed that the rich fraction of galloyl glucosides (particularly tetragalloyl glucoside and hexagalloyl glucoside) exhibited the highest free radical scavenging activities as well as inhibitory effects against oxidation process mediated by enzymes.…”

The aim of this study was to explore the potential of the agroindustrial waste from two Colombian mango cultivars as sources of bioactive phenolic compounds. Phenolic extracts from mango waste (peels, seed coats, and seed kernels) of ‘sugar mango’ and ‘Tommy Atkins’ cultivars were obtained. The bioactive properties of the phenolic extracts were accessed by measuring their free radical scavenging activity and antioxidant effects against lipid oxidation in food products; moreover, their antiproliferative effects against some cell lines of human cancer were explored. It is observed that the agroindustrial waste studied provides promising sources of bioactive phenolics. ‘Sugar mango’ waste provided extracts with the highest antioxidant effect in food products and antiproliferative activity; these extracts reduced lipid oxidation and cell growth by more than 57% and 75%, respectively. The seed kernel from ‘sugar mango’ supplied the extract with the best bioactive qualities; in addition, some recognized bioactive phenolics (such as mangiferin and several galloyl glucosides) were observed in this extract and related with its properties. The results obtained suggest that ‘sugar mango’ waste may be considered a source of bioactive phenolics, with promising uses in food and pharmaceutical products. Thus, a suitable alternative for the use and valorization of agroindustrial waste from Colombian mango cultivars is presented.

“…Silva et al, reported in 2020 from mono-to penta-galloyl hexosides in different parts (petals, stalks, and nectar) of C. hypocistis [24]. However, all these compounds were previously reported in other sources such as Magnifera indica L. kernels and peels [25,26], Rhodiola crenulate roots [27], Rhodiola rosea roots, leaves, stems and flowers [27], Paeonia plants [28], and Pistacia vera leaves [29], among others [30]. Table 1 shows that a major number of these gallotannins were found in ethyl acetate, ethanol, water/ethanol, and water extracts.…”

Selectivity Tuning by Natural Deep Eutectic Solvents (NADESs) for Extraction of Bioactive Compounds from Cytinus hypocistis—Studies of Antioxidative, Enzyme-Inhibitive Properties and LC-MS Profiles

et al. 2022

In the present study, the extracts of Cytinus hypocistis (L.) L using both traditional solvents (hexane, ethyl acetate, dichloromethane, ethanol, ethanol/water, and water) and natural deep eutectic solvents (NADESs) were investigated in terms of their total polyphenolic contents and antioxidant and enzyme-inhibitive properties. The extracts were found to possess total phenolic and total flavonoid contents in the ranges of 26.47–186.13 mg GAE/g and 0.68–12.55 mg RE/g, respectively. Higher total phenolic contents were obtained for NADES extracts. Compositional differences were reported in relation to antioxidant potential studied by several assays (DPPH: 70.19–939.35 mg TE/g, ABTS: 172.56–4026.50 mg TE/g; CUPRAC: 97.41–1730.38 mg TE/g, FRAP: 84.11–1534.85 mg TE/g). Application of NADESs (choline chloride—urea 1:2, a so-called Reline) allowed one to obtain the highest number of extracts having antioxidant potential in the radical scavenging and reducing assays. NADES-B (protonated by HCl L-proline-xylitol 5:1) was the only extractant from the studied solvents that isolated a specific fraction without chelating activity. Reline extract exhibited the highest acetylcholinesterase inhibition compared to NADES-B and NADES-C (protonated by H2SO4 L-proline-xylitol 5:1) extracts, which showed no inhibition. The NADES extracts were observed to have higher tyrosinase inhibitory properties compared to extracts obtained by traditional organic solvents. Furthermore, the NADES extracts were relatively better inhibitors of the diabetic enzymes. These findings provided an interesting comparison in terms of total polyphenolic content yields, antioxidant and enzyme inhibitory properties (cholinesterase, amylase, glucosidase, and tyrosinase) between traditional solvent extracts and NADES extracts, used as an alternative. While the organic solvents showed better antioxidant activity, the NADES extracts were found to have some other improved properties, such as higher total phenolic content and enzyme-inhibiting properties, suggesting functional prospects for their use in phytonutrient extraction and fractionation. The obtained results could also be used to give a broad overview of the different biological potentials of C. hypocistis.

“…Choke-Anan at the stage of maturity of around 110 days after the fruits were set, were obtained from an orchard in Nakornratchasima province, Thailand. Peel and pulp were removed from the fruits and the seeds were washed and stored at -18 o C. The preparation of mango seed kernel extract (MSKE) was done according to the method of Namngam et al [5]. A 50 g sample was blended with 500 ml of 95% ethanol for 5 min in a blender (Moulinex, Mexico), then incubated in a sonication bath (JAC Ultrasonic 2010P; Jinwoo Engineering Co., Ltd., Korea) at 20 KHz and 25°C for 15 min, followed by another incubation in a water bath at 80°C for 1 h. The mixture was cooled and filtered through a filter paper and then evaporated in a rotary evaporator (Büchi Rotavapor R II; USA) at 50°C under vacuum to get an extract with 70% solids.…”

“…The phenolic constituents of mango seed kernel and their bioactivities including antioxidant activity have been extensively reported [2,3]. The strong in vitro antioxidant properties and active phenolic components of Thai mango seed kernel extract (MSKE) from Kaew and Choke-Anan cultivars has previously been shown [4,5]. In addition, the application of MSKE as a natural antioxidant used to protect against oxidation in sunflower seed oil under accelerated storage [6] and in bologna-type meat products during refrigerated storage [7] has been reported.…”

Mango seed kernel extract (MSKE) has been reported to contain high content of phenolic compounds, and exhibit strong in vitro antioxidant activity. This study aimed to evaluate the application of MSKE as natural antioxidant in frozen minced fish products. The effect of MSKE at different concentrations (0%, 1%, 2% and 3% w/w) on retarding lipid and protein oxidation in minced fish samples during frozen storage at -18 ºC was investigated and compared to the chemical antioxidant, BHT (butylated hydroxytoluene) at 0.01% w/w. Physicochemical parameters related to the oxidative stability of minced fish samples including pH, color, peroxide value (PV), thiobarbituric acid reactive substances (TBARS), conjugated diene (CD), protein carbonyl, sulfphydryl groups (SH), and total volatile base nitrogen (TVB-N) were determined. The results showed that the pH values had significantly increased in all samples being treated with MSKE and BHT after 12 weeks of frozen storage. Samples treated with 3% MSKE or BHT were significantly lower in lightness (L*) and redness (a*) but presented no significant effects on yellowness (b*). Moreover, MSKE at all concentrations studied, and BHT, significantly delayed the increase in values of PV, TBARS, CD, protein carbonyl, and TVB-N and the decrease in values of SH compared to the control sample. At the end of storage, no significant odd odor and flavor assessed by sensory test were detected in frozen minced fish. In conclusion, MSKE at 3% w/w proved to be as efficient as BHT in retarding lipid and protein oxidation in minced fish during frozen storage.
