Abstract

Stress conditions will trigger the histone hyperacetylation process due to histone acetyltransferase p300/CBP (HAT PCAF) constantly transfers acetyl groups from acetyl-CoA to conserved lysine residues on histone proteins to form ε-N-acetyllysine. This can be a cause of cancer. The purpose of this study was to investigate the potential mechanisms and inhibition of PCAF HAT by chemical components of C. xanthorrhiza namely, curcumin, demethoxycurcumin, bisdemethoxycurcumin, and xanthorrizhol using in silico, the molecular docking method.  Results showed that the components of C. xanthorrhiza as ligands have the capability to inhibit the binding of acetyl-CoA to histone. These results can be used to predict the inhibitory mechanisms exhibited by C. xanthorrhiza components, as competitive and noncompetitive substances. We hypothesize that C. xanthorrhiza components resemble a substrate, leading to prevention of the natural substrate (histone) to bind to the enzyme, and hence block the product formation. The smallest free Gibs energy was exhibited by curcumin on chain B and by bismethoxycurcumin on chain A, with values of -8.8 and -8.4 Kcal/mol, respectively.

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.

Abstract

Herbal yang berperan sebagai antioksidan dan antikanker diantaranya temulawak. Penelitian pengaruh ekstrak temulawak terhadap hematologi tikus pada pengujian keamanan subkronis dilakukan pada penelitian ini.  Parameter hematologi yang ditentukan adalah nilai hemoglobin, hematokrit, dan jumlah leukosit. Hewan coba yang digunakan adalah tikus jantan dan betina dari galur Sprague Dawley. 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.

Abstract

Soursop is a plant that is used as traditional medicine. Antioxidants are compounds that are able to delay, slow down, or inhibit oxidation reactions. This study aims to determine the effect of variations in extraction time and the comparison of variations in the amount of simplicia with aquadest solvent on the high pressure extraction method on antioxidant activity. The study made 13 treatments using the Response Surface Methodology (RSM) design with the fit of the Central Composite Design (CCD) model. The results showed that from the 13 treatments, the extraction time had an effect on the percent yield with the equation Y = -51.9692 + 24.2030 X1 + 1.2984 X2. The extraction time (X1) has a value greater than the ratio of simplicia powder to the volume of distilled water (X2) as well as the IC50 value as shown in the equation Y = 171,983 + 13,828 X1 – 4,110 X2. Extraction time (X1) has a greater value when compared to simplicia with aquadest solvent volume (X2). The results of the analysis of the percentage of extract yield and the optimal IC50 value using RSM analysis were thought to have an extraction time of 6.3 minutes and the ratio of simplicia powder to the volume of aquadest solvent was 1:61,2. The results of the antioxidant activity obtained that the optimal IC50 value was estimated at 4.3 minutes of extraction time and the ratio of simplicia powder to the volume of aquadest solvent was 1:78.2.

Abstract

Traditional medicines that can be used as α-glucosidase inhibitors are turmeric (Curcuma longa L.), black tea (Camellia sinensi L), and ginger (Zingiber officinale). It is necessary to research the use of a combination of tea, turmeric, and ginger in inhibiting the α -glucosidase enzyme. This study aims to determine the optimal combination of extracts of turmeric, black tea, and ginger in inhibiting the α-glucosidase enzyme. The research carried out was the measurement of IC50 values for the inhibition of α-glucosidase of each extract, and the inhibition of the enzyme α-glucosidase in combination. The results of the test of ethanol extract of turmeric, ginger and black tea water extract obtained the inhibition value of α-glucosidase with IC50 values of 9.48±0.05 g/mL, 66.64±0.44 g/mL and 9.52±0.25, respectively. F7 is a combination of turmeric, ginger and black tea which produces the highest α-glucosidase inhibition, which is 67.86±0.93%.

Abstract

Propolis from Indonesia contains secondary metabolites which include flavonoids and other organic compounds. The ethanol extract of 70% propolis Trigona spp from Pandeglang can be used as an antibacterial compound. The purpose of this study was to examine the toxicity of the propolis and nanopropolis with an LC50 value, test the antioxidant activity with an IC50 value, and determine the total flavonoid content. LC50 was determined by the BSLT method on Artemia salina Leach larvae. The antioxidant activity was tested using the DPPH method (1,1 diphenyl-2-picrylhydrazil), and the determination of flavonoid content was carried out with aluminum chloride. The results showed that the LC50 value of propolis was 16.010 ppm, and for 20% nanopropolis was 18.689 ppm. Antioxidant activity obtained IC50 value for propolis is 95.54593 ppm, for 20% nanopropolis is 527.7939 ppm. The total flavonoid content of the propolis was 2.1123%, and the total flavonoid content for the nanopropolis equivalent extract was 1.5293%.
