Abstract

Honey is rich in phenolic and flavonoid compounds that have the potential as antioxidants. The heating treatment of honey is also known to affect the honey compound. This study aimed to determine the best Indonesian A. dorsata honey from various locations based on the level of total phenolics compounds, flavonoids, and antioxidant capacity due to variations in heating temperature. The procedures carried out in this study included: heating the sample with variations (room temperature, 65 oC, and 121 oC), measuring total phenolic content using the Folin-Ciocalteau method, measuring total flavonoid content using the AlCl3 colorimetric method, and testing antioxidant activity using the DPPH method. Each honey's total phenolic, flavonoid, and antioxidant activity are affected by its origin. The impact of heating at 65 oC and 121 oC resulted in various changes between honey samples (p<0.05). The best A. dorsata honey overall was found in Flores honey after heating at 121 oC heating treatment with total phenolic content of 4.96 mgGAE/mL, total flavonoids of 1.173 mg QE/mL, and IC50 5.76 g/L.

Abstract

Actinomycetes are known to be a source of natural products and drugs. Gordonia terrae, an actinomycete pigment producer, shows potential in producing pigment with antimicrobial activity. This study aims to determine the antimicrobial activity of the active pigment fraction produced by the actinomycete G. terrae, assess the effects of the active pigment fraction on microbial cells, and identify the types of compounds present in the fraction. The pigment extract exhibited antimicrobial activity against Gram-positive bacteria and fungi. Specifically, it showed activity against Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25293, and Candida albicans ATCC 10231. Furthermore, the study evaluated the antimicrobial activities of the active fractions, revealed the active fraction had better antimicrobial activity than the crude extract. Scanning electron microscopy (SEM) confirmed that the active fraction of the pigment causes damage to B. subtilis ATCC 6633 cells, inhibits the formation of filaments in C. albicans ATCC 10231, and alters the normal shape of the cells. LC-MS/MS results showed that the active fraction contained several compounds known for their antimicrobial activity. Among the dominant compounds identified were cholestyramine, aminopregnane, and sphinganine. Thus, this study demonstrated that the orange pigment extract derived from G. terrae JSN1.9 exhibits promising antimicrobial activity.

Abstract

Background: Glass ionomer cement (GIC) is a dental material often used in clinical practice. However, its use is limited due to its drawbacks. Natural resources such as propolis have been used to mainly enhance GIC’s antibacterial properties, but other properties attributed to this enhancement also require evaluation. Purpose: The study aims to evaluate the surface hardness, the surface roughness, and the water absorption of GIC containing ethanolic extract of propolis (EEP) from Trigona spp. Methods: Samples in this study were divided into four groups: GIC (control group); GIC + 25% EEP; GIC + 30% EEP; and GIC + 35% EEP. Surface roughness was measured using a surface roughness tester. Surface hardness was measured using a micro-Vickers hardness tester. Water absorption was measured by weighing the samples before and after immersion in distilled water. Surface characterization was carried out using a scanning electron microscope (SEM). Data was statistically analyzed using the Shapiro–Wilk normality test and one-way variance analysis along with the post-hoc Tukey’s test to determine significant differences between all four samples. Results: The statistical test showed significant differences in surface hardness and surface roughness between the control group and the GIC + EEP group. However, the test demonstrated no significant differences in water absorption between the control group and the GIC + EEP group. Conclusion: The addition of EEP to conventional GIC can affect its physical properties.

This study aims to determine the effect of bee pollen on the sperm quality of male rats. Administering 1 ml of water as control (-), 1 ml/kg of Eurycoma longifolia capsule as control (+), 1 ml/kg of nano bee pollen, and bee pollen with concentrations of 0.33 ml/kg, 0.66 ml/kg, 1 ml/kg, and 1.33 ml/kg 34 times in Sprague Dawley male white rats. The mice were then operated on and examined for testicular weight, epididymal weight, sperm pH, sperm motility, sperm concentration, and sperm abnormalities. The results showed that bee pollen and nano bee pollen did not significantly affect the quality of rat spermatozoa. In examining the testicular weight of rats, 0.33 ml/kg of bee pollen had an average testicular weight greater than the control group. For sperm weight and pH of the rat epididymis, the administration of bee pollen showed the average weight and pH were lower than the control. In the examination of sperm motility, 0.33 ml of bee pollen had a higher percentage than the control, while 1 ml of nano bee pollen had the lowest percentage of motility. The results of the concentration and abnormalities of rat spermatozoa from a dose of 1 ml/kg of bee pollen had an average sperm count higher than the control which was 2,129.7 million/ml and the lowest percentage of sperm abnormalities was 8.73%.

Abstract

Alzheimer's Disease (AD) is one of the consequences of impaired functioning of acetylcholine which can be hydrolyzed by the enzyme acetylcholinesterase. Alzheimer's treatment is carried out using two approaches, namely compounds (acetylcholinesterase inhibitors) and noncholinergics (antioxidants). There are commercial drugs that can slow the progression of Alzheimer's, but their use can cause excessive side effects. The use of herbal plants as a cure for Alzheimer's disease has been proven to be safer and does not cause excessive side effects. Herbal plants that can be used and developed are black tea, red betel, curcuma, and cinnamon. This study determined that extracts of black tea, red betel leaf, curcuma, and cinnamon's formula have the best antioxidant activity and level of inhibition of the acetylcholinesterase enzyme. F1 (cinnamon), F5 (cinnamon, black tea, red betel, and curcuma), F6 (cinnamon and black tea), and F11 (cinnamon, black tea, and curcuma) were the best formulations in each type of sample based on inhibitory AChE enzymes and antioxidants activity. F1 (cinnamon) is the most effective extract out of all formulations analyzed in this study. Keywords: Acetylcholinesterase; Alzheimer; Black Tea; Cinnamon; Red Betel; Curcuma

Abstract

Curcuminoids and xanthorizol are active components that may act as anticancer in the rhizome of Curcuma xanthorrhiza. The purpose of this study was to determine the content of the class of compounds in curcuma extract and essential oil using the phytochemical screening test method, the Folin-Ciocalteu method to determine the total phenolic content and the AlCl3 method for the total fentuconoid content. In addition, the activity of curcuma in inhibiting the influence of DMBA on the growth of breast cancer in rats was determined. Curcuma extract used is the result of extraction using 70% ethanol on an industrial scale. Total phenolic content and flavonoid extract of curcuma were determined by spectrophotometer. Inhibition testing of tumors formed due to DMBA induction was carried out by administering temulawak extract at doses of 35, 70, 140, 210 and 280 mg/kg body weight. Based on the phytochemical analysis, the ethanol extract of curcuma contained terpenoids, alkaloids, phenolic compounds and flavonoids. The results of the analysis of the ethanol extract of curcuma contained total phenols and flavonoids with concentrations of 42.96 mg GAE/g and 3.96 mg QE/g, respectively. The group that was given curcuma extract as the control group (p<0.05) had a significant difference. Based on the Mann-Whitney analysis, the third group with a dose of 140 mg/kg BW had the highest effect on tumor inhibition. The hope is that the development of curcuma extract into a standardized herbal medicine so that it can be used for the treatment of breast cancer can use the results of this research.

Herbal yang diberikan sebagai pengobatan adalah ekstrak etanol 70% temulawak yang diberikan sebanyak 5 hari dalam seminggu selama 28 hari dengan dosis bertingkat mulai dari 45 mg/Kg BB hingga 5.625 mg/kg BB. Hasil yang diperoleh adalah perlakuan terakhir tidak ada tikus yang mati. Berdasarkan pengukuran diperoleh nilai hemoglobin antara 12,57-17,97 g/dL, nilai hematokrit antara 31,77-51,57%, dan jumlah leukosit antara 5,01-23.22x103 sel/μL (normal). Kesimpulan dari penelitian ini adalah bahwa dosis lebih besar dari 5625 mg/kg BB merupakan nilai LD50 untuk ekstrak etanol 70% temulawak. Pemberian ekstrak etanol 70% temulawak hingga dosis 5.625 mg/kg BB selama 28 hari pada tikus jantan dan betina memberikan efek penurunan terhadap nilai hemoglobin, hematokrit, dan leukosit, namun nilainya masih dalam batas normal. Tidak ada perbedaan nyata antara tikus jantan dan betina pada hasil pengukuran nilai hemoglobin, hematokrit, dan leukosit. Kata Kunci: Dosis, Hematologi, Subkronis, Temulawak, Tikus  Herbs that act as antioxidants and anticancer include temulawak. Research on the effect of temulawak extract on rat hematology in subchronic safety testing was carried out in this study. The determined hematological parameters were the value of hemoglobin, hematocrit and the number of leukocytes. The experimental animals used were male and female rats from the Sprague Dawley strain. The herbs given as treatment were an ethanolic extract of 70% temulawak which was given 5 days a week for 28 days with a graduated dose ranging from 45 mg/Kg BW to 5625 mg/kg BW. The results obtained are the last treatment no rat died. Based on the measurement of hemoglobin values obtained between 12.57 to 17.97 g/dL, hematocrit values obtained between 31.77 to 51.57% and leukocyte counts obtained between 5.01 to 23.22x103 cells/μL were still in the normal range. The conclusion of this study is that a dose greater than 5,625 mg/kg BW is the LD50 value for the ethanol extract of 70% temulawak. Giving 70% ethanol extract of temulawak until a dose of 5,625 mg/kg BW for 28 days to male and female rats had a decreasing effect on hemoglobin, hematocrit, and leukocyte values, but the values were still within normal limits. There is no significant difference between male and female rats in the measurement results of hemoglobin, hematocrit, and leukocyte values.
