Pengaruh Trietanolamin pada Basis Krim Minyak dalam Air yang Berbahan Dasar Asam Stearat dan Setil Alkohol: Effect of Triethanolamine on Oil-in-Water Cream Base Based on Stearic Acid and Cetyl Alcohol

The cream is a semi-solid preparation with one or more ingredients dispersed in two types of emulsions, water-in-oil (W/O) and oil-in-water (O/W) type creams. Oil-in-water type cream has a high water content so that it can provide a hydration effect that can increase the penetration of the active substance. Triethanolamine in topical preparations is used as an emulsifier and alkalizing agent to form a homogeneous and stable cream. The purpose of this research was to determine the effect of triethanolamine on an oil-in-water cream base based on stearic acid and cetyl alcohol. Making the base is done by making preparations using four concentrations of triethanolamine 0.5% (F1), 1% (F2), 1.5% (F3), and 2% (F4). The cream base was then evaluated for its physical properties including organoleptic, homogeneity, pH, viscosity, spreadability, adhesion, and phase separation test. The results showed that in the organoleptic test cream bases were white, had a characteristic aroma with a semisolid form. The cream base has a homogeneity dispersion with an average pH between 6.53-7.29, viscosity between 3.5792396-3.8001904 (Pa.s), spreadability between 5.43-5.78 cm, and adhesion between 4.47-6.25 seconds. The cream base did not have phase separation and was stable in storage for 4 weeks at room temperature

Diabetes is a frightening disease that threatens people's lives, because almost every 10 seconds in the world, people die from complications of this disease. A new DM treatment approach in the creatinase system that inhibits dipeptidyl peptidase IV (Dpp-4) has been developed, and has been shown to effectively increase insulin secretion, maintain pancreatic -integration, and slow gastric emptying. antidiabetic, namely inhibition of the -glucosidase enzyme in one of its compounds and has not been found to inhibit the Dpp-4 enzyme. This study aims to determine the potential of the compounds in Dayak onions as inhibitors of the Dpp-4 enzyme. The method used is molecular anchoring or in silico because the research time is short and the cost is cheaper than in vitro or in vivo. The software used is autodock which is a device that can attach ligand molecules to receptor macromolecules. Then visualized using discovery studio 2020 and other devices to support tethering such as chemdraw and chimera 1.4. vidagliptin as an antidiabetic which has activity against inhibiting Dpp-4 inhibitors was used as a standard. The grid is placed on natural ligands with a box size of 52? x 28? x 26? and a center of 40,926? x 50,522? x 35,031? with a spacing of 0.375?. Based on the docking that has been done, the secondary metabolite compounds in Dayak onions have a low bond energy value, with the lowest value being -8.46 kcal/mol and the highest -5.54 with different values of inhibition constant and bond form. Eleuthoside C has the lowest bond energy of -8.46 and has the most similar interaction with natural ligands. The bond that occurs is the type of hydrogen bonding at the residues of Phe357, Arg125, Arg358, Tyr666, Tyr662, and Glu205. With this, Dayak onions have antidiabetic activity but further docking still needs to be done to see other compounds in Dayak onions as Dpp-4 inhibitors

Identifikasi Metabolit Sekunder Ekstrak Metanol Akar dan Batang Merung (Coptosapelta tomentosa ) yang Memiliki Aktivitas Antioksidan Menggunakan Metode KLT Autografi

Secondary metabolites produced by plants have been known to have a variety of biological activities including antioxidants that serve to ward off oxidant compounds and free radicals. The roots of merung (Coptosapelta tomentosa) has been known to have strong activity as an antioxidant while antioxidant activity in the stem is not yet known to date.  This research aims to determine the secondary metabolites that have antioxidant activity on the root extracts and the stem of the vines qualitatively. The root extract and the stem of the merung plant are extracted with a methanol solvent using the maceration method. Antioxidant activity and identification of secondary metabolites are carried out qualitatively by the method of autography using the 2.2-Diphenyl-1-Picrylhydrazyl compound (DPPH) and some reagents of the secondary metabolite. Antioxidant activity of the merung root extract is on spot with RF 0.08 and 0.66. Spot with the RF 0.66 shows the brown color when reacted FeCl3, fluorescent yellow in UV rays 254 and 366 nm after reacted AlCl3 and red when reacted with KOH. The antioxidant activity of the merung stem extracts is at Rf 0.16, 0.33, 0.58, 0.66, and 0.75. Spot with the Rf 0.16 shows the color of brown when reacted FeCl3 and fluorescent blue in UV rays 254 and 366 nm after reacted AlCl3. Secondary metabolites that have antioxidant activity on root extracts and stems are suspected to be derivative phenolic compounds derived from flavonoid compounds
