Leaf Extract in Emulsion Gels Against Candida albicans","authors":"Widyasari Putranti, Chairisty Asterina, Hardi Astuti Witasari","doi":"10.22146/MOT.53257","DOIUrl":"https://doi.org/10.22146/MOT.53257","url":null,"abstract":"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 These data were analyzed using the Mann-Whitney method, and the conclusion was withdrawn from describing the results quantitatively.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.","PeriodicalId":32438,"journal":{"name":"Majalah Obat Tradisional","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47168971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

This study aims to determine the fruit peel and heart of Raja Bulu banana (Musa acuminata Colla (AAB group)), an endemic banana species in Indonesia, potential as antioxidant and anticancer agent in MCF-7 cells. Antioxidant potential was determined by using 2,2-diphenyl-1picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) scavenging activity assay. Anticancer potential was determined by cytotoxic test using MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium).

The kidneys function to regulate fluid balance in the body the concentration of salt in the blood, acid-base balance in the blood, and excretion of waste materials such as urea and other nitrogenous waste in the blood. Magenta plants (Peristrophe bivalvis (L.) Merr.) contain secondary metabolites, namely alkaloids, saponins, triterpenoids, tannins, and flavonoids as antioxidants. The abundance of antioxidants sourced from natural sources for various diseases is often used as a complementary therapy and is one of the current therapeutic choices. However, the development of natural sources must also consider kidney function during an intervention. The incidence of kidney failure can be caused either by the occurrence of oxidative stress or exposure to drugs and other chemical compounds must also consider the physiological functions of important organs in the body such as the liver and kidneys. This study was conducted to determine the protective role of magenta leaves extract (Peristrophe bivalvis (L.) Merr.) on the kidneys after being given an acetaminophen hepatotoxic dose. In this study, the effectiveness of magenta leaves antioxidants and the safety of use was analyzed by looking at the kidney function in the experimental model of Wistar strain male white rats, using a Randomized Post Test Only Control Group Design. Four treatment groups showed that magenta leaves extract (Peristrophe bivalvis (L.) Merr.) at 125 and 250 mg/kg BW can protect the kidneys with average creatinine levels of 0.63 and 0.75 and with a normal range (0.7 - 1.2). It means that these two groups could protect the kidney function although in the histopathology test only the group administering extracts of 250 mg/Kg BW showed good results. It can be concluded that administration of the magenta leaves extracts at 250 mg/kg BW can protect renal function as seen from serum creatinine levels. Besides, histopathological features can provide a protective effect on the kidneys with the incidence of necrosis in the kidneys of less than 60% of the toxic dose of acetaminophen.","PeriodicalId":32438,"journal":{"name":"Majalah Obat Tradisional","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41681106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of extracts, buas-buas, meniran, secang, and rosella which are used in sequence is (1: 1: 1/2: 1/2), (1: 2: 1/2: 1/2), and (2: 1 : 1/2: 1/2).
