Abstract

ABSTRAK Kopi robusta (Coffea canephora) merupakan salah satu jenis kopi, mengandung asam klorogenat dan kafein yang berpotensi menurunkan berat badan. Selain biji kopi, saat ini penelitian berkembang kepada pemanfaatan limbah kulit biji kopi. Adanya kandungan bioaktif polifenol sebagai sumber antioksidan, menjadikan kulit biji kopi memberikan manfaat kesehatan tambahan, salah satunya untuk menurunkan berat badan pada penderita obesitas. Tujuan dari penelitian ini adalah mengetahui golongan senyawa dan menganalisis penurunan indeks Lee (indeks obesitas) dari ekstrak etanol 96% kulit biji kopi robusta terhadap mencit putih jantan model obesitas yang diinduksi pakan tinggi lemak. Penapisan fitokimia dilakukan secara kualitatif dan pengujian aktivitas penurunan indeks Lee menggunakan metode Pretest dan Posttest Control Group Design pada enam kelompok mencit yaitu satu kelompok normal tanpa induksi, lima kelompok induksi yang masing-masing diberi CMC-Na 0,5% (kontrol negatif); Orlistat (kontrol positif); Ekstrak 200; 400; dan 800 mg/kg BB. Hasil penelitian menunjukkan ekstrak kulit biji kopi robusta mengandung golongan senyawa alkaloid, flavanoid, saponin, tanin, steroid, dan terpenoid. Ekstrak etanol 96% kulit biji kopi robusta berpotensi menurunkan indeks Lee. Penurunan terbesar ditunjukkan oleh kelompok ekstrak 200 mg/kg BB. Kata kunci: Coffea canephora, Indeks Lee, Kulit biji kopi, Mus musculus, Obesitas ABSTRACT Robusta coffee (Coffea canephora) is one type of coffee, containing chlorogenic acid and caffeine which have the potential to reduce weight. In addition to coffee beans, research is currently developing into the utilization of coffee bean skin waste. The presence of bioactive polyphenol content as a source of antioxidants, makes coffee bean skin provide additional health benefits, one of which is to reduce weight in obese people. The purpose of this study was to determine the group of compounds and analyze the decrease in the Lee index (obesity index) from 96% ethanol extract of robusta coffee bean skin on male white mice with obesity models induced by high-fat feed. Phytochemical screening was carried out qualitatively and testing the activity of reducing the Lee index using the Pretest and Posttest Control Group Design method on six groups of mice, namely one normal group without induction, five induction groups each given 0.5% CMC-Na (negative control); Orlistat (positive control); Extract 200; 400; and 800 mg/kg BW. The results showed that robusta coffee bean skin extract contains alkaloid, flavonoid, saponin, tannin, steroid, and terpenoid compounds. 96% ethanol extract of robusta coffee bean skin can potentially reduce the Lee index. The largest decrease was shown by the 200 mg/kg BW extract group. Keywords: Coffea canephora, Cofee bean skin, Lee index, Mus musculus, Obesity

Abstract

Alzheimer's disease is a progressive neurological disorder that can impact adults aged 65 and beyond. A primary factor contributing to Alzheimer’s is the diminished availability of the neurotransmitter acetylcholine in the brain. Plants from the Lamiaceae family have been believed to possess potential as acetylcholinesterase inhibitors (AChEI) that can alleviate the symptoms of Alzheimer’s disease. This study aims to find possible bioactive compounds from plants of the Lamiaceae family, specifically Salvia officinalis L., Salvia lavandulifolia Vahl., Rosmarinus officinalis L., Collinsonia canadensis L., and Melissa officinalis L., as acetylcholinesterase inhibitors using in silico approaches. Active compounds from the Lamiaceae family were evaluated based on physicochemical properties, toxicity, Gibbs free energy (∆G), inhibition constant (Ki), absorption, excretion, metabolism, distribution, and molecular dynamics. From a total of 1,370 compounds derived from Lamiaceae plants, the compound 3,5,5-Trimethyl-4-[3-[3,4,5-trihydroxy-6-(hydroxymethyl) oxan-2]-yl]oxybut-1-enyl] cyclohex-2-en-1-one (TOC) from Salvia officinalis L. exhibited potential as an AChEI, possessing a molecular weight of 370 Daltons, 4 hydrogen donors, 7 hydrogen acceptors, a Log P partition coefficient of 3.46, a molar refractivity of 100, a Gibbs free energy change (∆G) of -11.2 kcal/mol, an inhibition constant (Ki) of 0.981 μM, and a total energy calculated via Molecular Mechanics Generalized Born Surface Area of 31.381 kcal/mol. In silico, the TOC ligand inhibits acetylcholinesterase to treat Alzheimer's.

Abstract

Dengue haemorrhagic fever is a viral infection transmitted by the Aedes aegypti mosquito, which is one of the symptoms is thrombocytopenia. The extract from white sweet potato leaves is recognized for its potential to increase the number of platelet count. This research aimed to develop a formula for an instant granule combining white sweet potato leaves extract with Javanese chili extract meeting taste preferences and societal acceptability. The preparation of the extract was performed by maseration using 70% ethanol and then concentrated with a rotary evaporator. The result was a thick extract which was then dried in an oven at 50℃. The manufacture of instant granule formulations was conducted using wet granulation method. Various formulations were obtained by differentiated concentration of Javanese chili used in the formula (FI 1%, FII 2%, and FIII 3%). The instant granule formulation was evaluated by organoleptic assay and other essential parameters for instant granule, such as moisture content, flow rate, angle of repose, and particle size distribution. The FII 2% formulation emerged as the most acceptable with an average score of 2.17. Non-parametric analysis indicated no significant difference among the three formulas, as the obtained significant value (α) was ≥ 0.05, leading to the acceptance of the null hypothesis H0.
