Optimization of HIB Value Combination of Tween 60 and Span 80 on Cream Formulation of Ethanol Extract of Green Tea Leaves (Camellia Sinensis L.)
Get PDFGreen tea (Camellia sinensis L.) is known to have ability to protect skin against free radicals. This is supported by polyphenol compound catechin. This research aims to determine the optimum Hydrophilic-Lipophilic Balance (HLB) value of Tween 60 and Span 80 compositions on the optimum cream formula of ethanol extract of green tea leaves. Tea leaves are extracted by macerating using 70% ethanol. Catechin in extract is known from Thin Layer Chromatography (TLC) test with silica gel 60 F254 as stationary phase and ethyl acetate:aquadest:formic acid (18:1:1 v/v) as mobile phase. Antioxidant activity is determined by 2,2-Diphenyl-1-picryhydrazyl (DPPH) method and value of Inhibition Concentration 50% (IC50) is then calculated. Formula optimization using Design Expert® version 7.1.5 (DX 7) software, Simplex Lattice Design (SLD) method with two components Tween 60 and Span 80. Cream is characterized according to physical properties organoleptic, homogeneity, viscosity, pH, spreadability, adhesiveness, and cream type. The optimum formula obtained is then tested for physical stability for 4 weeks at room temperature (28±2°C) and data are statistically analyzed using one-way ANOVA. The extract contains catechin proved with Retention factor (Rf) value 0.8 and has antioxidant activity with IC50 value 56.35 ppm. 6.4% Tween 60 and 3.6% Span 80 result an optimum HLB value 11.1. It has viscosity 2897.50±35.94 mPa.s, spreadability 18.44±0.06 cm2, adhesiveness 0.85±0.05 seconds, and pH 4.530±0.002. Statistical test shows that the cream is significantly altered at pH, but does not significantly change in viscosity, spreadability, and adhesiveness after being stored for 4 weeks

Get PDFThe mangosteen peels (Garcinia mangostana L.) has high free radical scavengers activity. This study aims to determine the physical and chemical conditions that are formulated in SNEDDS and nanoemulsion preparations. SNEDDS was made with various concentrations of Tween 80, PEG 400, and Virgin Coconut Oil (VCO) with a ratio of 4,98:1,02:1. Nanoemulsions were made with the addition of water to SNEDDS. Stability observation results were analyzed by statistics. The results of physical stability test show that all test samples in the research, in nanoemulsion, SNEDDS fraction, base SNEDDS, SNEDDS vitamin E did not undergo separation, precipitation, cracking, and creaming. On the chemical stability test of nanoemulsion and SNEDDS fraction there is no difference between IC50 before and after storage. While on basic SNEDDS and vitamin E nanoemulsion there is a difference between IC50 before and after storage

The data obtained were analyzed using principal component analysis (PCA). The results show that based on morphological and anatomical assessment, there were found 3 clusters of S. dulcis, i.e. Cangkringan-Ngemplak-Prambanan, Kalasan, and Imogiri-Pundong cluster
Radical Scavenging Activity Combination of Sambiloto (Andrographis paniculata Nees.) and Patikan Kebo (Euphorbia hirta L.) Ethanolic Extracts on 2,2-Diphenyl-1-Picrylhidrazyl (DPPH)
Get PDFResearch of radical scavenging activity of sambiloto (Andrographis paniculata Nees) and patikan kebo (Euphorbia hirta L) ethanolic extracts and their combination toward 2,2-Diphenyl-1-Picrylhidrazyl (DPPH) has conducted. Subjects of this experiment comprise sambiloto ethanolic extract, patikan kebo ethanolic extract, dechlorophyllated extract of sambiloto and combinations among those three. Dechlorophyllation by electrocoagulation method is done to reduce chlorophyll content thereby increasing the level of active compound in the sambiloto extract. The results of dechlorophyllation showed that only total flavonoid content in the extract of sambiloto increased, meanwhile the radical scavenging activity results showed that patikan kebo ethanolic extract has the lowest IC50 value (22,36 µg/mL) compared to sambiloto ethanolic extract (IC50 value 499,03 µg/mL). Extract combination may increase DPPH radical scavenging activity of the sambiloto extract (IC50 value 76,06 µg/mL) but not higher than that of patikan kebo single extract

Get PDFPrevious research revealed that the extracts and fractions of Tithonia diversifolia (Hemsley) A.Gray leaves had antiplasmodial activity in vitro. For further development as an antiplasmodial agent, the mechanisms of action and safety of compounds are important to disclose. Heme polymerization inhibition is one of the main targets of antiplasmodial action. The aim of the study was to investigate the activity of T. diversifolia fractions in inhibiting heme polymerization and its cytotoxic effect on Vero cells. Heme polymerization inhibition assay from Bassilico and cytotoxic test on Vero cell using MTT method were conducted for three fractions (F5, F6, and F7) of T. diversifolia leaves. The inhibitory activity of heme polymerization expressed as IC50 and cytotoxicity effect expressed as CC50 were determined by probit analysis. The best heme polymerization inhibition activity was F5 with IC50 = 162.20 ± 57.81 μg/mL followed by F6 and F7 with IC50 216.30 ± 26.56 and 231.54 ± 44.26 μg/mL respectively. All the fractions had a low cytotoxic effect with CC50 for F5, F6, and F7 were over than 100, 34.81 ± 9.94 and 56.26 ± 6.73 μg/mL, respectively and the toxicity index fraction is below 10 or categorized as low selectivity. Conclusion: The fraction of T. diversifolia inhibited heme polymerization in vitro and had low cytotoxic effect on Vero cells but no selective toxicity. Further research using pure compounds may improve its selectivity

Get PDFOxidative stress has been known to contribute to Alzheimer’s disease. Acetylcholinesterase (AChE) enzyme may lead to Alzheimer’s disease as a neurotransmitter. Antioxidants may have protective activities against oxidative damage and Alzheimer’s disease. Acetylcholinesterase inhibitors also can be used in the treatment of various neurological disorders for management of Alzheimer’s disease. This study aimed to determine antioxidant and anticholinesterase effects of Garcinia picrorrhiza Miq. fruit extract (GpKar) and its compounds, xanthone. Antioxidant activity was measured by H2O2 scavenging inhibitory activity, while anticholinesterase activity was measured using modified Ellman method. GpKar has higher H2O2 scavenging inhibitory activity (IC50= 967.28 µg/ml) compared to xanthone (IC50= 1198.95 µg/ml). In the anticholinesterase inhibitory activity, GpKar has lower activity (IC50= 70.25 µg/ml) compared to xanthone (11.80 µg/ml). In summary, GpKar has higher antioxidant activity but lower anticholinesterase activity compared to its compounds, xanthone. However, GpKar has potency as antioxidant agent to prevent Alzheimer’s disease

Electrocoagulation are performed using copper, silver, aluminum and iron plates as the electrode. Dechlorophyllation by extraction using n-hexane is performed as reference. The % absorbance of chlorophyll and % of total phenolic content of dechlorophyllated samples are measured spectrophotometrically. Electrocoagulation process reduces % absorbance of chlorophyll in Cosmos caudatus Kunth., Morinda citrifolia, and Mangifera indica L. leaves methanolic extract. The more the duration of electrocoagulaton process the lower the % absorbance of chlorophyll obtained. % absorbance of chlorophyll of the electrocoagulated extract according to paired t-test (P=0.95) are significantly different with the previous. One way ANOVA continued with LSD (P=0.95) shows that the % absorbance of chlorophyll from the electrocoagulated extract are significantly different with those extracted with n-hexane. Electrocoagulation process reduces total phenolic content along with duration of electrocoagulation
