Obesity caused by a high-fat diet leads to an altered reproductive hormonal profile, including impaired semen quality. Antioxidants can overcome these conditions. One of the well-known sources of antioxidants is in the rambutan fruit peel extract. This research aimed to figure the effect of rambutan fruit peel extract towards total sperm count in Wistar rats induced with high-fat feed. The study design used post-test only control group,  subjects were 30 male Wistar rats divided into five groups: Group I (Positive Control) was given high-fat feed, Group II (Treatment Control Group) was given 15mg/kg BW rambutan fruit peel extract, whereas group III, IV, V (Treatment Group) were given an extract of rambutan skin with a dosage of 15, 30, and 60 mg/kg BW, respectively. Treatment was administered for 81 days. This study showed that rambutan fruit peel extract with doses of 15, 30, and 60 mg/kg BW has significantly increased total sperm count in Wistar rats induced with high-fat feed. The outcome using Kruskal Wallis shows a result of p-value 0,010 (CI 95%). Antioxidant compounds found in rambutan fruit peel extract significantly increase total sperm count in Wistar rats induced with high-fat feed, with the highest efficacy on the dose of 15mg/kg BW.   Keywords: Fruit Peel Rambutan Extract; ; ;

The objective of the research is to analyze the content of the bioactive compounds of extracts made of snake fruit skin, Aloe vera, and Stevia as materials to make functional drinks. Salacca zalacca (Gaert.) Voss. cultivar has flavonoid, tannin, and a bit of alkaloid on its fruit peel. Aloe vera and Stevia also known to have antioxidant compounds. Aloe vera controls the metabolism of carbohydrates and maintaining homeostasis of glucose. The research methods are divided into steps: 1) the extraction of Snake fruit peel, Aloe vera, and Stevia; 2) the formulation of the functional drink; 3)the evaluation of antioxidant, total phenol, and tannin levels of the formulated extracts. The research used Randomized Group Design (RGD) of two factors, and each factor consists of 4 levels and 2 levels. Factor I=the ratio of snake fruit peel:Aloe vera extract (10:90 (v/v); 30:70 (v/v); 70:30 (v/v); 90:10 (v/v)) and factor II= addition of Stevia filtrate (2%; 4%) (v/v total). The best nutrient of the formulated functional drink is obtained by the composition of 90% snake fruit peel extract, 10% aloe vera, and 4% stevia. The snake fruit peel extract significantly affects the antioxidant activity and total phenol composition, aloe vera extract has an insignificant effect on active compounds, and stevia affects the tannin level of the functional drink.

The use of colorants in the dried noodle manufactures is an effort of product diversification. Besides of being used as a natural coloring agent, this peel extract is also used to improve nutritional value of the expected product. The purpose of this study was to determine the effect of red dragon fruit peel extract on the physical quality of dried noodle.  The study was conducted by using Completely Randomized Design (CRD) method with one factor, namely concentration of red dragon fruit peel extract (N1 = 10 ml, N2 = 15 ml, N3 = 20 ml, N4 = 25 ml, N5 = 30 ml).  The observations of its physical quality consisted of water absorption, solid loss during cooking, and organoleptic tests (aroma and color).  The best quality of dried noodle was obtained by using 30 ml red dragon fruit peel extract (N5) with physical properties, namely DSA levels of 351.92%, solid loss during cooking 4.78%, aroma 3.79 (like) and color 3.89 (like).

The aim of the present study was the full characterization, quantification, and determination of the digestive stability and bioaccessibility of individual betalain and phenolic compounds of Opuntia stricta, var. Dillenii fresh fruits (peel, pulp, and whole fruit) and of the products of the industrialization to obtain jam (raw pressed juice (product used for jam formulation), by-product (bagasse), and frozen whole fruit (starting material for jam production)). Opuntia stricta var. Dillenii fruits and products profile showed 60 betalain and phenolic compounds that were identified and quantified by HPLC-DAD-ESI/MS and HPLC-DAD-MS/QTOF, being 25 phenolic acids (including isomers and derivatives), 12 flavonoids (including glycosides), 3 ellagic acids (including glycosides and derivative), and 20 betanins (including degradation compounds). In vitro gastrointestinal digestion was performed by INFOGEST® protocol. Fruit pulp showed the greater content of total betalains (444.77 mg/100 g f.w.), and jam only showed very low amounts of two betanin degradation compounds, Cyclo-dopa-5-O-β-glucoside (and its isomer) (0.63 mg/100 f.w.), and two Phyllocactin derivatives (1.04 mg/100 g f.w.). Meanwhile, fruit peel was the richer tissue in total phenolic acids (273.42 mg/100 g f.w.), mainly in piscidic acid content and total flavonoids (7.39 mg/100 g f.w.), isorhamnetin glucoxyl-rhamnosyl-pentoside (IG2) being the most abundant of these compounds. The stability of betalains and phenolic compounds during in vitro gastrointestinal digestion is reported in the present study. In Opuntia stricta var. Dillenii pulp (the edible fraction of the fresh fruit), the betanin bioaccessibility was only 22.9%, and the flavonoid bioaccessibility ranged from 53.7% to 30.6%, depending on the compound. In non-edible samples, such as peel sample (PE), the betanin bioaccessibility was 42.5% and the greater bioaccessibility in flavonoids was observed for quercetin glycoside (QG1) 53.7%, the fruit peel being the most interesting material to obtain antioxidant extracts, attending to its composition on antioxidant compounds and their bioaccessibilities.

Effective use of antimicrobial agents for treatment/management of infectious diseases is decreasing due to emergency of multi-drug and cross resistant strains of pathogenic microbes. Medicinal plants are now increasingly used alone or as an adjunct in the management of infectious diseases as a result of their claimed efficacy and safety. This research focused on evaluating the antimicrobial potential of ethanol fruit peel extract of Mangifera indica against isolated Urinary tract infection (UTI) pathogens. Urinary tract infection (UTI) bacterial strains (staphylococcus aureus, escherichia coli and pseudomonas aeruginosa) were isolated from midstream urine of infected students using standard procedures after which the isolated Urinary tract infection pathogens were subjected to antimicrobial susceptibility test by agar-well diffusion method (Cup plate method) and the mean diameter of growth inhibition zones (n=3) of the extract at different concentrations were compared against the controls (sterile water and ciprofloxacin). Ethanol fruit peel extract of Mangifera indica significantly and dose dependently inhibit the growth of all the isolated Urinary tract infection pathogens with E.coli exhibiting the highest inhibition zone ranging from 16.83 to 28.23 mm, this was followed by pseudomonas aeruginosa with inhibition zone of 24.33 mm and staphylococcus aureus least susceptible with 22.63 diameter of zone inhibition. Ethanol fruit peel extract of Mangifera indica demonstrated a dose dependent antimicrobial activity with more pronounced effect exhibited by E. coli suggesting that the extract is more effective against gram negative bacteria despite their permeability barrier, thus suggesting Mangifera indica fruit peel as a potential candidate for the management of bacterial infections especially those caused by gram negative organisms.

The main aim of this study was to screen the selected fruit peel extracts and their polyherbal mixture (PHM) for hepatoprotective activity. Male wistar albino rats (180-200 g), divided into 12 groups after induction of hepatotoxicity, were treated with selected fruit peel extracts and PHM and at the end of 14th day blood and liver samples were collected and analysed. The aqueous peel extract of Malus pumila was a better hepatoprotective among the selected peel extracts. The activities might be due to the conditioning of hepatocytes by protecting the integrity of the membrane from CCl4 induced leakage of serum markers into circulation. All the selected plant extracts and PHM were shown to revert back the liver enzymes to the normal values in diseased rats in a dose dependent manner. In conclusion, the selected fruit peel extracts and poly herbal mixture can be a potent hepatoprotective agent due to their antioxidant and anti-inflammatory actions.
