Abstract

Tekelan (Choromolaena odorata L.) merupakan tanaman yang mengandung senyawa yang dapat berperan sebagai antioksidan. Tujuan penelitian ini dilakukan untuk identifikasi kandungan senyawa dan mengetahui potensi ekstrak etanol 96% daun tekelan menggunakan metode ABTS. Simplisia yang diperoleh selanjutnya diekstraksi dengan metode maserasi menggunakan etanol 96%, dihitung rendemennya dan diidentifikasi kandungan senyawa menggunakan metode KLT kemudian dilakukan uji aktivitas antioksidan dengan metode ABTS. Diperoleh hasil penelitian yaitu kadar air simplisia 9%, rendemen ekstrak 12,4%, kandungan senyawa dalam ekstrak etanol daun tekelan yaitu alkaloid, flavonoid, steroid dan tannin menggunakan metode KLT. Nilai IC50 ekstrak yaitu 28,323 μg/mL menunjukkan aktivitasnya sebagai antioksidan dan pembanding kuersetin dengan nilai IC50 2,334 μg/mL. Dapat disimpulkan potensi antioksidan ekstrak etanol 96% daun tekelan memiliki aktivitas antioksidan yang sangat kuat, hal ini dikarenakan adanya kandungan senyawa flavonoid yang memiliki potensi sebagai antioksidan. Tekelan (Choromolaena odorata L.) is a plant that contains compounds that can act as antioxidants. The aim of this research was to identify the compound content and determine the potential of a 96% ethanol extract of tekelan leaves using the ABTS method. The simplicia obtained was then extracted using the maceration method using 96% ethanol; the yield was calculated; the compound content was identified using the TLC method; and antioxidant activity was tested using the ABTS method. The results obtained were that the water content of simplicia was 9%, the extract yield was 12.4%, and the compound content in the ethanol extract of tekelan leaves was alkaloids, flavonoids, steroids, and tannins using the TLC method. The IC50 value of the extract is 28.323 μg/mL, indicating its activity as an antioxidant and a comparison for quercetin with an IC50 value of 2.334 μg/mL. It can be concluded that the antioxidant potential of the 96% ethanol extract of tekelan leaves has very strong antioxidant activity. This is due to the content of flavonoid compounds, whichhave potential as antioxidants.

Abstract

Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin production or utilization. The increasing prevalence of diabetes, especially type 2, is a global concern due to the risk of complications it poses. One approach in treating type 2 diabetes is to inhibit the α-glucosidase enzyme to slow down glucose absorption. This research aims to identify the potential of patikala leaf extract as an α-glucosidase enzyme inhibitor. Using an experimental method with patikala leaf samples collected from Mariri Hamlet, Banyuurip Village, Bone-bone District, North Luwu Regency. Extraction was performed using the maceration method with variations in solvents: 70% ethanol, ethyl acetate, and n-hexane. The α-glucosidase enzyme inhibition activity was measured using a microplate reader and analyzed to determine the IC50 value. From the percentage inhibition data, the IC50 values obtained for 30% ethanol extract of patikala leaves were 351.95 µg/mL, for 70% ethanol extract of patikala leaves were 444.83 µg/mL, for 96% ethanol extract of patikala leaves were 362.27 µg/mL, for ethyl acetate extract of patikala leaves were 163.59 µg/mL, and for n-hexane extract of patikala leaves were 294.90 µg/mL, indicating that patikala leaf extracts with variations in solvent or extraction method exhibited very weak α-glucosidase enzyme inhibition activity. In conclusion, based on the research results obtained, the extract with variations in the solvent or extractant. Patikala leaf extract has an inhibitory activity against the α-glucosidase enzyme, which is categorized as very weak because it has an IC50 value > 100 µg/mL. In comparison, the control (acarbose) is in the weak category with an IC50 value of 50-100 µg/mL.

In Minahassa, leilem leaf generally consumed as vegetables. The present study revealed that leilem leaf can inhibit the growth of escherhia coli because of the presence of flavonoid that can demage bacterial cell membranes. This study at characterization of isolated compounds from ethanol extract of leilem leaves (Clerodendrum minahassae Teijsm and Binn). Extraction was done maceration using 70% ethanol with the percentage of rendement was 10,19%. The phytochemical analysis of ethanol extract of leilem leaves showed a positive result of alkoloid, flavonoid, streroid and tanin.

Abstract

Acne treatment can be derived from natural ingredients that contain antibacterial substances such as tannins and flavonoids, one of which is green tea with the aroma of Jasminum sambac L. The aim of this study was to formulate anti-acne preparations at several concentrations of F1 (0.5%), F2 (1%), and F3 (1.5%) in cream formulation and to test the physical stability of the ethanol extract cream of J. sambac. This research was conducted by extracting J. sambac tea dregs by the maceration method using 96% ethanol solvent. Physical evaluation of the preparation was carried out on three cream formulas, including organoleptic test, homogeneity, pH test, viscosity, spreadability, adhesion, and cream type test. The ethanol extract of J. sambac tea pulp can be formulated into a cream dosage form. The stability of both F1 (0.5%) and F2 (1%) cream formulations showed pH values that did not meet the requirements. F3 results were obtained that met the requirements for physical evaluation, including organoleptic showing a stable, homogeneous preparation, pH value 7.84, viscosity test 34,167 cPs, spreadability of 5.4 cm, and adhesion of 03.19 seconds. Therefore, it can be concluded that F3, with a concentration of 1.5%, is the most physically stable.
