“…Thus, HHP treatment helps to extract bioactive compounds efficiently from plant tissues . During HHP, the solvent easily enters the cell, and as the solubility and permeability increase, the more compounds penetrate into the cell membrane, leading to higher yields of extraction . Plant cell wall degrading enzymes and HHP treatments are synergistic in the degradation of plant cell wall and are effective in the extraction of active ingredients.…”

BACKGROUND Enzymatic hydrolysis and high hydrostatic pressure (HHP) are common processing techniques in the extraction of active compounds from food materials. The aim of this study was to investigate the effects of enzymatic hydrolysis combined with HHP treatments on ginsenoside metabolites in red ginseng. RESULTS The yield and changes in the levels of polyphenol and ginsenoside were measured in red ginseng treated with commercial enzymes such as Ultraflo L, Viscozyme, Cytolase PCL5, Rapidase and Econase E at atmospheric pressure (0.1 MPa), 50 MPa, and 100 MPa. β‐Glucosidase activity of Cytolase was the highest at 4258.2 mg−1, whereas Viscozyme showed the lowest activity at 10.6 mg−1. Pressure of 100 MPa did not affect the stability or the activity of the β‐glucosidase. Treatment of red ginseng with Cytolase and Econase at 100 MPa significantly increased the dry weight and polyphenol content of red ginseng, compared with treatments at 0.1 MPa and 50 MPa (P < 0.05). The amounts of ginsenoside and ginsenoside metabolites derived from red ginseng processed using Cytolase were higher than those derived from red ginseng treated with the other enzymes. Treatment with Cytolase also significantly increased the skin and intestinal permeability of red ginseng‐derived polyphenols. CONCLUSION Cytolase could be useful as an enzymatic treatment to enhance the yield of bioactive compounds from ginseng under HHP. In addition, ginsenoside metabolites obtained by Cytolase hydrolysis combined with HHP are functional substances with increased intestinal and skin permeability. © 2019 Society of Chemical Industry

“…From the results obtained in table 4, dried extracts had lower total flavonoid correlations with DPPH (r =0.634, P < 0.01) compared with fresh extracts. This suggests the presence of compounds in the extracts with relatively weak radicalscavenging activity but maybe have a good metal-chelating ability that can prevent the generation of hydroxyl radicals (Scepankova et al, 2018).…”

“…The free radical scavenging activity of ice soy milk extracts (Table 2) increased by increasing the percentage of fruits through the donation of proton forming the reduced DPPH (Scepankova et al, 2018). The highest scavenging activity was recorded by FK 15% as (96.0%), followed by FK 10% (95.3%) and finally (93.3%) at a concentration of FK 5%, While in fresh papaya ice soy milk extracts, the scavenging activity ranked as follows: 15% FP (95.4%) > 10%FP (94.8%) > 5% FP (93.3%) providing that the antioxidant activity depends on the component.…”

Lactose-free products are still not suitable for people who suffer from food allergy. Therefore, the present investigation was carried out to enhance the functional properties of ice soy milk fortified with different percentage of fresh kiwi (FK) and papaya (FP) at (5%, 10% and 15%) as well as a powder (KP and PP) at 0.5%, 1% and 1.5%. Fortifications led to an increment of the total flavonoids content to 40% with FP and 69% with FK, total phenols (20% and 35%) and tannins (36% and 60%) in FK and FP ice soy milk compared to control, respectively. Using citric acid before drying led to a loss of total phenols, flavonoids and tannins content by only 13%, 16% and 27%, respectively. Carotenoids were found to be at the highest level in ice soy milk with 15%FP in comparison to PP1.5% and FK15%. On the other hand, incorporation of kiwi or papaya powder causes decrements in overrun value. Ice soy milks were considered microbiologically safe. A high positive significant correlations were observed between ice soy milk bioactive components and DPPH, TP(r=0.638,P<0.01), tannins(r=0.673,P<0.01) and TF(r=0.727,P<0.01), as well as it had a negative significant correlation with NEB(r=-0.823,P<0.01) and yellow flavonoid(r=-0.829,P<0.01). The 'b' value was increment with increased percentage of fresh fruits and had a significant strong correlation with carotenoids(r=0.943,P<0.01), TP(r=0.871,P<0.01) and tannin(r=0.818,P<0.01). Ice soy milk produced with FK 15% as well as FP 10% could be used as a healthy acceptable frozen product especially people who suffer from lactose intolerance and food allergy syndromes.

“…Plant extracts as a mixture of many chemical compounds may possess more interesting biological activities due to their components (among others aromatic plant pigments) can interact one with another and show antioxidant effect in depending on the extraction techniques i.e. using solvents with various polarity, microwave-assisted or ultrasonic-assisted extractions [22], non-thermal high hydrostatic pressure extraction [24] and supercritical extraction [25,26]. It is considered that obtaining plant extracts using fast and appropriate techniques is a low-cost method.…”

Comparison of in vitro antioxidative activities of crude methanolic extracts of three species of Passiflora from greenhouse using DPPH, ABTS and FRAP methods

Summary Introduction:. It is well documented that many species from Passifloraceae family can provide edible and nutritious fruits while the leaves of cultivated plants are renewable and waste material. This biomass may be further used in various sectors, especially as a bioactive food additive and as source of innovative pharmaceuticals, cosmetics or feed additives. The biomaterials and green chemistry are new sectors bioeconomy according to the high-level horizontal strategies and bio-based industries in Europe. In recent years, attention has been paid to the biological activity and phytochemical profiles of extracts from different species of Passiflora. However, there is little comparative studies using the same procedures and techniques in the same laboratory conditions for study of plant material obtained from the similar greenhouse conditions. Objective: This study was focused on the examination of antioxidative activities of low concentrations of crude extracts from leaves of Passiflora incarnata L., Passiflora caerulea L., and Passiflora alata Curtis. Methods: The activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging and ferric reducing antioxidant power (FRAP) methods. Results of study were supported by estimation of chemical composition with secondary metabolites profiling in extracts which were carried out previously for the same extracts from three Passiflora species. One-way ANOVA analysis revealed significant differences in the antioxidant activity of various concentrations of the extracts using the DPPH and ABTS radical models, and FRAP method. Results: Measurement of antioxidant capacity (expressed as trolox equivalent, TE) showed that the most active was extract of P. caerulea > P. alata > P. incarnata. Phytochemical analysis for extracts of P. caerulea and P. incarnata showed greater similarities in metabolites content than P. alata. However, comparative statistical analysis of antioxidant activity showed that despite this phytochemical similarities, extract from P. alata leaves had higher activities than extract from leaves P. incarnata. Antioxidant effect of extract from P. alata can be explain by terpenoids presented in this extract. In this work, there have been discussed activities against Acanthamoeba castellanii strain, antibacterial and antifungal activities against selected clinical microorganisms (Enterococcus faecalis, Escherichia coli, Staphylococcus aureus, and Candida albicans, Micro-sporum gypseum), and anti-leukemic activities tested in human acute lymphoblastic leukemia cell lines for this extracts, which have been described in previous authors’ publications. Conclusion: Our current and previous studies showed that the same crude extracts from leaves of P. alata, P. caerulea, P. incarnata exerted not only antioxidant potential in vitro but also few interesting properties such as antibacterial, antifungal, amoebostatic, amoebicidal activities, which indicate the possibility of using these extracts in both a healthy diet and natural cosmetics. Leaves of this species may become an interesting source of biomaterials which can exert health-promoting effects.
