Cream scrub is a body scrub that contains slightly harsh ingredients with cream-based ingredients. In this study, onion extract (Allium cepa L.) and chicken eggshell powder were used in order to determine which emulgator concentration (Span-Tween 80) could provide the best stability of cream scrub. Onion extract was made by maceration using methanol solvent to obtain liquid extract, afterward concentrated using vacuum rotary evaporator until a thick extract was obtained. There were 3 concentration variation of emulgator used for each 100 g of cream scrub formulation, namely 1% (F1), 2% (F2), and 3% (F3). Evaluation of cream scrub included organoleptic test, homogeneity test, dispersion test, emulsion type test and pH measurement. The results showed that all three cream scrub formulations were homogeneous and the cream scrub had M/A emulsion type. The results of dispersion test showed that F2 cream scrub had greater dispersibility than F1 and F3. Emulgator span-tween 80 with a concentration of 2% provided the best stability for cream scrub formulations.

The purpose of this research is to determine the growth of guava cuttings (Syzygium equaeum) by administering a chemical and natural growth regulator from onion extract (Allium cepa L). This study uses Factorial Randomized Block Design (RBD) consisting of 2 treatment factors and 3 replications. The first treatment is the utilization of chemical growth regulators, which consist of C0: no chemical growth regulator, C1: 20 ml chemical growth regulator / 1 liter of water) / cuttings; C2: 20 ml chemical growth regulator / 2 liters of water) / cuttings. The second treatment is the application of natural growth regulators onion extract, which consist of A0: no onion extract, A1: 20 ml onion extract /1 liter of water / cuttings, A2: 30 ml onion extract / 2 liters of water) / cuttings. The highest growth results of cuttings are in C0A1, C0A2 and C2A2, because of auxin and gibberellin hormone in C0A1 and C0A2 where the auxin lengthen the stem and roots, and the gibberellins support the leaf growth, and elongation of shoots and roots.

Fermented onion is a type of onion that produced by heating onion bulbs at high temperature for 15 days by fermenter machine. This research is expected to produce new alternatives therapy for reducing cholesterol from onions especially Allium cepa L. var cepa. In this experimental laboratory used 25 male white rats that divided into five groups, group I: negatif control, group II: positif control (Atorvastatin), group III: 100 mg/Kg body weight (bw) of fermented onion extact, group IV: 200 mg/Kg bw of fermented onion extract and group V: 300 mg/Kg bw of fermented onion extract. The Rats was feeding by an atherogenic diet to makes them hypercholesterolemia before treatment for 7th days, 14th days and 21st days. All of data were analyzed by ANOVA method (significant 0,05). The result concludes that of all the doses tested, fermented onion extract of Allium cepa L. var cepa with a dose of 200 mg/Kg bw has the highest effect in decreasing total cholesterol levels of hypercholesterolemia rats (Rattus novergicus).

AbstractBackgroundAllium species extracts including Allium cepa L. contain sulfur compounds, known for their antiplatelet, antimicrobial, antineoplasic activities.MethodologyAntibacterial activity of a formulation based on A. cepa extracts-liquid and lyophilized samples, has been demonstrated using two classes of bacteria: Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) and three methods: discs soaked with liquid extract, the wells method in the culture medium, filled with the liquid extract and lyophilized formulation extracts transformed by the incorporation of ultrapure water. The second part of this study includes identification of thiosulfinates compounds from the studied samples by high performance liquid chromatography - mass spectrometry (HPLC-MS).ResultsThe most important inhibition and the highest antibacterial effficiency were observed against Gram-positive bacteria, such as Staphylococcus aureus. The HPLC-MS thiosulfinates profile of the tested formulation extracts shows the presence of seven thiosulfinate compounds, MeS(O)S 1-propenyl (E,Z); n-PrS(O)S 1-propenyl-(E); n-PrS(O)S 1-propenyl-(Z); trans-zwiebelane; n-PrS(O)CHEtSS-1propenyl; 1-propenylS(O)CHEtSS1-propenyl, which may be responsible for antibacterial activity.ConclusionTesting antimicrobial effects using the three mentioned methods confirmed the antimicrobial activity of the tested samples based on A. cepa extracts, with a demonstrated content of seven thiosulfinate compounds.

This study aimed to determine the influence of onion extract cream (Allium cepa) for burning burns in white rats (Rattus norvegicus). The research was experimental with a concentration of 45%, 50%, and 55% onion Cream Extract (Allium cepa). The Data can then be processed using the Kruskall Wallis test. From the statistical test results, each  level of Bakart wound showed noticeable difference. The  P < 0.05 is thus distinct from  P1, P2, and P3. At the level of fluid burns Sig 0.000, because (P < 0.05) There were noticeable difference in the treatment of PO with P1, P2, and P3. The conclusion of this study of the introduction of onion extract Cream (Allium cepa.) can be used for wound healing in white rats (Rattus norvegicus).

Emulsifier Concentration

The formulation and physical characterization test of rosella extract cream preparations have been carried out using various types of non-ionic emulsifier concentration ratios (combination of tween 80 and span 80). Comparison of the concentrations of tween 80 and span 80 used in this study were 2%, 3%, and 4%. The aim of this study included organoleptic test, homogeneity test, pH test, viscosity test, dispersion test, and emulsion type test. The result obtained from the physical characterization test were the organoleptic tests for the three formulas showed the same organoleptic results, namely red color, characteristic smell of rosella, and semisolid consistency. Homogeinity test shows that the formula is homogenous. The pH test showed that F1 4,29; F2 4,6; F3 5. Viscosity test showed that F1 432,4 mPas; F2 434,3 mPas; 435,3 mPas. The dispersion test was carried out without using a load of 50 g, 100 g, and 200 g. the results shown form the spreadability test of three formulas were were F1 5 cm; 5,5 cm; and 6 cm; F2 6 cm; 6,35 cm; 7,25; and 7,5 cm. F3 6,25 cm; 7,5 cm; 7,75 cm; 8 cm. The emulsion type indicated by the three formulas is oil in water. Based on these results, it can be seen that the emulsifier concentration has an effect on PH, viscosity, and spreadibility. The higher the concentration of emulsifier used, the higher pH value, viscosity, and spreadibility.
