Accelerated Stability Test of Snakehead Fish Extract (Channa striata) and Kelulut Honey (heterotrigona itama) Ointment Combination with Tween 80 and Span 80 as an Emulsifying Agent
The combination of Snakehead Fish and Kelulut Honey has activity in accelerating the wound healing process. The ointment with active ingredients of Snakehead Fish extract and Kelulut Honey showed separation from the active ingredient and its base. The addition of tween 80 and span 80 is expected to increase the stability of the ointment preparation by keeping the water-phase droplets distributed uniformly on the ointment base. This study aimed to determine the effect of adding Tween 80 and Span 80 on the stability of the ointment preparation. The ointment was made by varying Tween 80 and span 80 by 2,5%: 5%: 7,5% and control (active ingredients without the addition of tween 80 and Span 80) as a comparison. The preparation was subjected to an accelerated stability test using a temperature of 40 ° ± 2 ° C / Relative humidity 75% ± 5% for 28 days by observing the organoleptic test, adhesion, spreadability, homogeneity test, pH test, and protection power. The data obtained were analyzed statistically using One Way Anova. The analysis showed that the addition of tween 80 and span 80 with a total concentration of 5% and 7,5% had a significant effect in increasing the spreadability, decreasing adhesion, and reducing the pH of the preparation. Formulas that meet the requirements in this study are F2 and F3, which have an average spreadability of 5,11 cm and 5,25 cm, adhesion of 96 seconds and 51 seconds, and pH of 6,02 and 5,02
Modeling and Optimization of Mitragyna speciosa Extraction using Box Behnken Design
The extraction of kratom (M. speciosa) leaf powder was optimized with preliminary extraction to be further optimized with the Box-Behnken experimental design. The individual and interactive effects of process variables (sample-to-solvent ratio, extraction time, solvent concentration) were assessed. The preliminary extraction results showed that ultrasound-assisted extraction (UAE) and methanol were chosen for further optimization. The experimental data were analyzed by Pareto analysis of variance (ANOVA) and second-order polynomial models were developed using multiple regression analysis. The model developed showed a good fit with the experimental data with a high coefficient of correlation (R2) and predictive ability (predicted R2). An optimization study was performed and the optimal extraction conditions were sample-to-solvent ratio value 1.5:10; extraction time of 10 minutes, and methanol concentration of 100%
Flavonoid Compounds of Buah Merah (Pandanus conoideus Lamk) as a Potent Oxidative Stress Modulator in ROS-induced Cancer: In Silico Approach
Buah Merah, a typical fruit from Papua, Indonesia which is used empirically in cancer therapy is rich in carotenoids and flavonoids. However, the mechanisms by which Buah Merah ameliorates cancer remained unknown. Natural antioxidant enzymes and pro-oxidant enzymes modulation significantly suppressed ROS production and cancer growth. Therefore, the determination of target enzymes of Buah Merah contents was studied through an in silico approach. Carotenoid and flavonoid compounds from Buah Merah were docked to 7 ROS modulating enzymes using Autodock Vina and the interaction stability was studied using the CABS Flex 2.0 server. The crucial amino acids of each enzyme were determined using DockFlin and prediction of acute oral toxicity of each test ligand was studied using ProTox-II. Based on the molecular docking results, quercetin 3'-glucoside is the most potent compound in binding to CAT, GR, GPx, SOD, LOX, and NOX with binding energy values of -11.2, -9.7, -8.6, -10.2, -10.7, and -12.8 kcal/mol, respectively. Meanwhile, taxifolin 3-O-α-arabinopyranose produced the highest binding affinity of -10.0 kcal/mol at the XO. Each test ligand formed stable interactions with ROS modulating enzymes and formed bonds with crucial amino acids resulting in strong adhesion compared to native and reference ligands. The glucoside group of quercetin 3'-glucoside plays an essential role in determining the proper position in the attachment and supports the formation of hydrogen bonds with receptors. With low acute oral toxicity, it can be concluded that quercetin 3'-glucoside from Buah Merah is a potent oxidative stress modulator in cancer prevention and therapy
In Vivo Antihypercholesterolemic Potential of Uncaria cordata (Lour.) Merr as Ethanolic Extract
The present investigation aims to evaluate the antihypercholesterolemic potential of Uncaria cordata (Lour.) Merr. as an ethanolic extract in diet-induced hypercholesterolemic male white mice model. In this study, white mice were segregated into 6 groups; all the groups except the normal control group were given a high-fat diet to induce hypercholesterolemia. After induction of cholesterolemia, normal and negative control groups were treated with NaCMC, the positive control group was treated with atorvastatin, and the remaining three groups received ethanolic extract Uncaria cordata (Lour.) Merr. in three doses (100, 200, and 400 mg/Kg BW) for a treatment period of 29 days. Measurement of cholesterol levels was performed on days 0, 15, 22, and 29 using EasyTouch® GCU digital devices. The results were analyzed by one way ANOVA test and ANOVA Repeated test. The results showed that the ethanol extract of the Uncaria cordata (Lour.) Merr. root plant dose 100, 200, and 400 mg/Kg BW effect in lowering total cholesterol in male white mice significantly (P <0,05). Ethanol extract from Uncaria cordata (Lour.) Merr. a dose of 200 mg/Kg BW showed a better decrease in cholesterol levels on day 29 compared to day 22
Renal Protective and Lipid Profile Modulatory Effects of Ethanol Extract of Anthocleista vogelii Stem Bark (EASB) in Renal Injury Rats Induced with Carbon-tetrachloride (CCl4)
The study evaluated the effects of ethanol extract of Anthocleista vogelii stem bark (EASB) on renal function indices and lipid profile in rats induced renal injury with CCl4. Following a completely randomized experimental design, 30 rats were randomly distributed into 6 groups (n = 5). Group 1 was the normal control, group 2 was the negative control while group 3 was the silymarin control. Groups 4 – 6 were CCl4 induced but treated with 100, 200, and 400 mg/kg EASB/day respectively. The study was conducted using appropriate methods. The results showed that the negative control had a significant (P0.05) increase in the serum HDL concentrations relative to the negative control. The rats treated with EASB had elevated serum LDL and cholesterol concentrations in comparison with the negative and silymarin controls. Treatments with EASB prevented the tubular necrosis, degeneration, and infiltration of inflammatory leucocytes observed in the kidney histomorphology of the negative control. These findings suggest that EASB improves renal function and some lipid profile parameters but could cause dyslipidemia when taken in excess dose
Formulation and Antifungal Activity of Piper betle L. Leaf Extract in Emulsion Gels Against Candida albicans
Candidiasis is the most common fungal infection in humans and is a form of primary and secondary infections of C. albicans. Betel (Piper betle L.) leaf extract has been reported to exhibit efficacious antifungal effects against C. albicans. Emulsion gels, a type of topical dosage form, can deliver hydrophilic and hydrophobic drugs and perform multiple and controlled releases. This research aimed to determine the antifungal activity and physical properties of emulsion gels formulated from betel leaf extract. The dried betel leaves were extracted by maceration with alcohol 95%. Then, with different concentrations (1, 2, and 4%), the extract was formulated into emulsion gels. These dosage forms were later subjected to antifungal activity testing against C. albicans using the cup plate diffusion method that involved Mycoral Cream® for comparison. In this test, the intensity of the activity was determined by measuring the diameter of the formed inhibition zone. The second test evaluated the physical characteristics of the dosage forms, including organoleptic properties, pH, adhesion, dispersion, and viscosity. These data were analyzed using the Mann-Whitney method, and the conclusion was withdrawn from describing the results quantitatively. The reaction yield of the extraction was 9.702%. The analysis results showed that emulsion gels containing 1, 2, and 4% of betel leaf extract created zones of inhibition with diameters of 5.3 ± 0.29, 6.2 ± 0.29, and 10.2 ± 0.41 mm, respectively. As for the physical properties, they differed in pH (6.39 ± 0.120, 6.17 ± 0.132, 5.66 ± 0.123), spreadability (1.849 ± 0.45, 1.816 ± 0.051, 1.771 ± 0.092 g.cm.s-1), adhesion (110 ± 10.8, 126.3 ± 8.5, 142.7 ± 13.50 seconds), and viscosity (2640.35, 1992.95, 2162.12 cps), respectively. The betel leaf emulsion gels exhibited antifungal activity against C. albicans (p <0.05) and met the physical requirements of semi-solid dosage forms
Antitussive Activity of Herbal Cough Medicine on Guinea Pigs (Cavia porvellus)
This study aims to investigate the antitussive activity of herbal cough medicine containing combined herbal extracts of Echinacea purpurea, Sambucus nigra (Black Elderberry), Glycyrrhiza glabra (licorice), Vitex trifolia (Indian wild pepper), and Zingiber officinale (ginger). Antitussive assays were conducted on male Dunkin-Hartley albino guinea pigs (Cavia cobaya), which are divided into 5 groups, each with 8 individuals. These 5 groups were assigned for negative control group (treated with CMC-Na 0.5%), a positive control group (treated with Dextromethorphan 20 mg/kg BW), and three groups receiving herbal medicine with 3 different doses (Group I: 145 mg/kg BW, Group II: 290 mg/kg BW; Group III: 580 mg/kg BW, respectively). The antitussive activity was evaluated by using a citric acid-induced cough assay. For baseline level, 20 % m/v liquid citric acid was exposed using a nebulizer for 10 min, then the number of coughs in 15 min was counted. Sixty (60) minutes after oral administration of the tested herbal cough medicine, the number of citric acid-induced coughs was counted again to see the effect of herbal cough medicine to reduce cough. The number of coughs before and after herbal administration was calculated to obtain antitussive activity, represented by the percentage of cough suppression (PCS). Average PCS for each treatment group is then compared to control positive Dextromethorphan 20 mg/kg BW and control negative CMC-Na 0.5%. Data are analyzed by applying the one-way ANOVA method, which is followed by conducting a Tukey’s Test to discover differences between groups at 95% level of confidence. In terms of the percentage of cough suppression (PCS), treatment doses at 145mg/kg BW, 290 mg/kg BW and 580 mg/kg BW result in 58.48% ± 8.60% (Group I); 58.69% ± 7.96% (Group II); 59.21% ± 8.79% (Group III) PCS, respectively, which insignificantly differ to treatment with Dextromethorphan dose (66.99% ± 9.63 with p > 0.05, implicating that the herbal cough medicine has comparable effect with dextromethorphan in the doses used in this study
The Effects of Green Betel Leaf (Piper betle) Extract Eye Drops on the Number of Staphylococcus aureus Colonies in Conjunctivitis Wistar Rats Model (Rattus novergicus)
Irrational use of antibiotics can cause resistance to some diseases such as bacterial conjunctivitis caused by Staphylococcus aureus. Previous research said that green betel leaf (Piper betle) contains antimicrobial compounds such as eugenol, cavalry, tannins, saponins, and flavonoids which also have antiseptic power as well as antibiotics. This study aims to prove the decrease in the number of Staphylococcus aureus colonies after giving green betel leaf eye drops (Piper betle) to conjunctivitis Wistar rats (Rattus norvegicus). This research was true experimental with a pretest-posttest control group design. 25 male white Wistar rats as objects were selected by simple random sampling and grouped into 5 groups randomly. The rats were given Staphylococcus aureus, control group K+ was given 0.5% levofloxacin eye drops, and K- was given aquadest as a comparison. Treatment groups P1, P2, and P3 were given different concentrations of betel leaf eye drops. Swab pretest was done 3 days after the rats were inoculated with Staphylococcus aureus and swab post-test was done 5 days after the rats were given green betel leaf eye drops, the calculation of Staphylococcus aureus bacteria colonies used the Total Plate Count (TPC) method. There was a significant decrease (p<0.05) in the number of bacterial colonies for K-, K+, P1, P2, and P3 groups. In addition, there was a significant difference (p<0.05) between K+ with P1 and K+ with P3. There was a decrease in the number of Staphylococcus aureus for all groups of conjunctivitis Wistar rats (Rattus norvegicus
Effect of AGE and Gamma-mangostin on Luteinizing Hormone Receptor (LHR) Levels in Leydig Cell Culture of Male Aging Rats: Preliminary Study
Advanced Glycation End Products (AGE) are proteins that can cause cell destruction by increasing oxidative stress and inflammation. This product resulted from a series of chemical reactions after an initial glycation reaction. A Leydig cell is one of the types of cells affected by AGE. This cell is located in the interstitial of the testes and stimulated by the luteinizing hormone. This study aimed to compare the luteinizing hormone receptor levels in Leydig cell culture of Sprague-Dawley rat induced by AGE only and the one that administered gamma-mangosteen. We conducted an experimental laboratory study on luteinizing hormone receptor levels in Leydig cell culture of Sprague-Dawley rats induced by advanced glycation end products 200 μg/mL and given gamma-mangostin 5 μM compared to the one that was not given gamma-mangostin. The highest mean of LHR level was in group 3 given gamma-mangostin 5 μM (8.06 pg/ cells/24h), and the lowest mean was in group 1 (control) (7.78 pg/ cells/24h). The LHR levels in the rats' Leydig cell culture given 5μM gamma-mangostin were higher than the other groups indicate the inhibition capacity on the oxidation process caused by AGE in aging rats Leydig cells culture
