Background: As a result of high percentage of women infected with urinary tract infection (UTI) annually, many rural dwellers use Adansonia digitata fruit pulp as herbal cure. Adansonia digitata L. (Malvaceae) is one of the great trees idolised in Africa because of its therapeutic properties.Aim: This study aimed at identifying chemical compounds in the ethylacetate fraction of the baobab fruit pulp and indicated their biological activities to justify its use for the folkloric treatment of UTI.Methods: The crude extract from Baobab fruit pulp was partitioned and ethylacetate extract was used for assay. Gas chromatography-mass spectrometry (GC–MS) analysis was performed to identify the bioactive compounds in the ethylacetate fraction, antioxidant activity was evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays whilst the total phenolic and flavonoid contents were determined by already adopted protocols. The antibacterial properties were tested against some urinary tract pathogens using macro broth dilution method.Results: A total of 36 bioactive compounds were identified by GC–MS analysis, most of them have been reported as antibacterial, antioxidant, antidiabetic, antiasthma, antifungal, anti-inflammatory and anti-cancer agents. The extract exhibited highest activity against Pseudomonas aeruginosa American Type Culture Collection (ATCC) 19582 (1.22 mg/mL) whilst Escherichia coli ATCC 8739 (˃ 8.6 mg/mL) displayed high level of resistance amongst the five bacterial isolates used in this study.Conclusion: These findings indicated that the extract contained bioactive compounds of therapeutic importance with significant antioxidant and antibacterial potentials and justify the folkloric use of this fruit in the treatment of UTIs by many African dwellers.

This study investigated the health-promoting activities of methanolic extracts of Ajwa date seed and fruit pulp extracts through in vitro studies. These studies confirmed potential antioxidant, anti-hemolytic, anti-proteolytic, and anti-bacterial activities associated with Ajwa dates. The EC50 values of fruit pulp and seed extracts in methanol were reported to be 1580.35 ± 0.37 and 1272.68 ± 0.27 µg/mL, respectively, in the DPPH test. The maximum percentage of hydrogen peroxide-reducing activity was 71.3 and 65.38% for both extracts at 600 µg/mL. Fruit pulp and seed extracts inhibited heat-induced BSA denaturation by 68.11 and 60.308%, heat-induced hemolysis by 63.84% and 58.10%, and hypersalinity-induced hemolysis by 61.71% and 57.27%, and showed the maximum anti-proteinase potential of 56.8 and 51.31% at 600 μg/mL, respectively. Seed and fruit pulp inhibited heat-induced egg albumin denaturation at the same concentration by 44.31 and 50.84%, respectively. Ajwa seed showed minimum browning intensity by 63.2%, percent aggregation index by 64.2%, and amyloid structure by 63.8% at 600 μg/mL. At 100 mg/mL, Ajwa seed extract exhibited good antibacterial activity. Molecular docking analysis showed that ten active constituents of Ajwa seeds bind with the critical antioxidant enzymes, catalase (1DGH) and superoxide dismutase (5YTU). The functional residues involved in such interactions include Arg72, Ala357, and Leu144 in 1DGH, and Gly37, Pro13, and Asp11 in 5YTU. Hence, Ajwa dates can be used to develop a suitable alternative therapy in various diseases, including diabetes and possibly COVID-19-associated complications.

This study investigated the effect of co-ingesting Natal plums (Carissa macrocarpa) and Marula nuts (Sclerocarya birrea) on the bioaccessibility and uptake of anthocyanins, antioxidant capacity, and the ability to inhibit α-glucosidase. A Natal plum–Marula nut bar was made by mixing the raw nuts and the fruit pulp in a ratio 1:1 (v/v). The cyanidin-3-O-sambubioside (Cy-3-Sa) and cyanidin-3-O-glucoside content (Cy-3-G) were quantified using the ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOF-MS). Inclusion of Natal plum in the Marula nut bar increased the Cy-3-Sa, Cy-3-G content, antioxidants capacity and α-glucosidase inhibition compared to ingesting Marula nut separately at the internal phase. Adding Natal plum to the Marula nut bar increased bioaccessibility of Cy-3-Sa, Cy-3-G, quercetin, coumaric acid, syringic acid and ferulic acid to 80.2% and 71.9%, 98.7%, 95.2%, 51.9% and 89.3%, respectively, compared to ingesting the Natal plum fruit or nut separately.

Introduction: Inflammation and fever are common clinical manifestations of many deadly diseases. Members of the genus Terminalia were discovered to have the ability to alleviate inflammation and fever. As a result, this research examined the in-vivoanti-inflammatory and antipyretic properties of aqueous fruit pulp extract of Terminalia bellirica in mice and rats. Methods: The acute and subacute anti-inflammatory effects of the plant were evaluated using Carrageenan-induced paw edema. The antipyretic effect of the plant was evaluated using Baker’s yeast-induced pyrexia model. The extract was given to three experimental groups (9 mg/kg, 18 mg/kg, and 36 mg/kg), with Indomethacin 10 mg/kg and Paracetamol 100 mg/kg servings as positive controls for anti-inflammatory and antipyretic tests, respectively. Negative controls for anti-inflammatory and antipyretic testing were with 1% Gum acacia suspension of 3 ml/kg and 10 ml/kg, respectively. Results: In acute anti-inflammatory activity tests, using the Carrageenan paw edema model, TB18 and TB36 displayed a significant reduction in mean paw edema (P<0.01). In subacute anti-inflammatory activity tests, TB36 displayed a significant reduction in mean paw edema (P<0.01). In Baker’s yeast-induced pyrexia tests, the rectal temperature reduced significantly (P<0.0001) in all experimental groups. Conclusion: In summary, the findings of this study showed that the extract displayed significant anti-inflammatory and antipyretic characteristics in mice and rats accordingly.

Research background. Cocoa honey (CH) and cocoa pulp (CP) are both fruit pulps highly appreciated but, until now, CH is less processed than CP. In this work, it was investigated the applicability of strains of S. cerevisiae to ferment CH complemented with CP, to obtain fruit wines and improve CH commercialization. Experimental approach. The selection of a strain, previously isolated from cachaçaria distilleries in Brazil, took place based on its fermentation performance. The conditions for fermentation with S. cerevisiae L63 were then studied in relation to: volumetric proportion (φCH) of CH (complemented with CP), sucrose addition (γsuc), temperature (T) and inoculum size (No). The best conditions were applied in order to obtain fermentation profiles. Results and conclusions. S. cerevisiae L63 (No=107–108 cell/mL) is capable to ferment φCH of 90 and 80 % (V/V) for 24 or 48 h with γsuc of 50 and 100 g/L at T=28–30 °C resulting in wines with ethanol contents from 8 to 14 % (V/V). Additionally, the φCH=90 % (V/V) wine resulted in the lowest residual sugar concentration (<35 g/L) than the φCH=80 % (V/V) wine (~79 g/L) which could be classified as a sweet wine. In general, S. cerevisiae L63 resulted in a similar fermentation performance than a commercial strain tested, indicating its potential for fruit pulp fermentation. Novelty and scientific contribution. Therefore, S. cerevisiae L63 is capable to ferment CH complemented with CP to produce fruit wines with good commercial potentials that may also benefit small cocoa producers by presenting a product with greater added value.

This study was conducted to assess the microbial changes during the fermentation of Baobab (Adansoniadigitata)fruit pulp yoghurt. The Baobab fruit pulp yoghurt was prepared in the Laboratory using the conventional method. Lactobacillus bulgaricus and Streptococcus thermophilus were used as starter cultures while a control was produced without the starter cultures. de Man Rogosa Sharpe (MRS) agar was used to culture lactic acid bacteria. The microbialload, succession and percentage occurrences were determined using standard methods. The total aerobic bacterial count wasfound to be within the range of 1.9x103 - 1.4x105 cfu/ml. The Lactic acid bacteria and fungal count ranges were 4.5 x 103  - 7.5 x 103  cfu/ml and 8.0 x 101 – 2.8 x 104  cfu/ml respectively. At the end of fermentation time, there was significant difference between the test and control Baobab yoghurt at P<0.05.  Lactic acid bacteria recorded the highest count of 6.2 x 104  and 7.5 x 103 cfu/ml in the test and control respectively. Bacillus species , Staphylococcus aureus, Lactobacillus bulgaricus,Streptococcus thermophilus and Micrococcus species were the bacteria isolated while the fungal isolates were Saccharomyces cerevisiae and Hansenula species. Lacbacillusbulgaricus, Streptococcus thermophilus, Bacillus species and Saccharomyces cerevisiae were the only microorganisms found at the end of fermentation time. The study obtained low microbial count and isolated less number and type of microorganisms from Baobab fruit pulp yoghurt because of the antimicrobial effect of baobab pulp and pasteurization treatment.Based on the results of this study, Baobab fruit pulp yoghurt can be said to be of good microbiologicalquality for human consumption. The industrial use of Baobab fruit pulp in the production of yoghurt is recommended.
