Abstract

Peel-Off face mask is one of the cosmetics that is used to treat skin from free radicals. Coffee (Coffea arabica) contains chlorogenic, ferulic, caffeic, and n-coumaric acids which can be useful as antioxidants. Turmeric (Curcuma longa) contains curcumin, which has anti-inflammatory and antioxidant properties. The purpose of this study is to evaluate the quality parameters and analyzed the antioxidant activity of peel-off masks containing coffee (Coffea arabica) and turmeric (Curcuma longa). This research has made 3 mask formulas, each of which contains coffee and turmeric. The formula made was a combination of coffee and turmeric with a ratio of each formula F1 (10:0), F2 (5:,5) and F3 (0:10). The result of organoleptic parameters for F1 was dark brown with coffee aroma and consistency like gel, F2 wasyellowish-brownn with spiced coffee aroma and consistency like gel and F3 was yellow with turmeric aroma and consistency like gel. The result of the homogeneity test of all formulasmula was homogeny. The result of the pH value of all formulasmula was 5. The resulspreadabilityd ability of F1, F2 and F3 were 26.877 cm2; 26.278 cm2; 26.875 cm2. The drying time of each formula was F1 27.36 min; F2 28.38 min; F3 28.54 min. The antioxidant activity is shown the by IC50 value. The value of IC50 for each formula F1 (37.277 ppm), F2 (34.757 ppm), and F3 (37.399 ppm). The test results showed that all formulas met the quality test requirements and had very strong antioxidant activity.

Abstract

Daun kersen mengandung senyawa flavonoid, saponin, polifenol dan tanin sehingga dapat digunakan sebagai antioksidan. Penelitian ini bertujuan untuk mengetahui kadar polifenol dan flavonoid pada ekstrak daun kersen (Muntingia calabura L.) segar dan kering. Metode penelitian yang digunakan pada penelitian ini adalah true eksperimental. Analisis data menggunakan analisis bivariat dengan uji independet sample t-test. Hasil kadar polifenol ekstrak daun kersen kering sebesar 3,295±0,128 mg GAE/g sampel dan untuk ekstrak daun kersen segar sebesar 3,398±0,0673 mg GAE/g sampel. Hasil kadar flavonoid ekstrak daun kersen kering sebesar 0,288±0,0157 mg QE/g sampel dan untuk ekstrak daun kersen besar sebesar 0,535±0,0423 mg QE/g sampel. Data yang diperoleh dilakukan uji statistik dan dilanjutkan uji t- Test dan menghasilkan masing-masing perlakuan dengan nilai signifikansi 0,001 < 0,05 dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan adanya perbedaan yang signifikan pada kadar polifenol pada daun segar dan daun kering dan kadar flavonoid pada daun daun kersen (Muntingia calabura L.) segar dan daun kering

Abstract

Natural immunomodulators are obtained from herbal plants with natural antioxidant content.The content of polyphenol compounds as natural antioxidants in katuk leaves and cocoa beansis utilized in the form of instant powder preparations.This study aimed to determine the levels of polyphenols and the antioxidant activity of instantpowder combination of katuk leaves and cocoa beans.Material dan Methods : this study used a quantitative descriptive method with test parametersincluding organoleptic, moisture content, ash content, polyphenol qualitative, polyphenolcontent and antioxidant activity.The results of the instant powder moisture content test were 1.71 ± 0.04%; 1.68 ± 0.03%; and1.59 ± 0.03%. The results of the instant powder ash content test were 1.16 ± 0.03%; 1.18 ±0.04%; and 1.11 ± 0.03%. The positive instant powder qualitative test results containedpolyphenols as indicated by the formation of blackish-brown color. Polyphenol levels in instantpowder were 43.83 ± 1.76 mg GAE/g; 34.40 ± 0.71 mg GAE/g; and 29.50 ± 0.76 mg GAE/g.The instant powder is classified as a medium antioxidant category with an IC50 value of 119.25ppm respectively; 129.25 ppm; and 146,40 ppm.The Conclusion Formula 1 is a formula that has a large polyphenol content and strongantioxidant activity.
