Abstract

Alstonia scholaris R.Br belongs to family Apocynaceae, is one of medicinal forest plant as traditional medicine to treat fever, malaria, cough with phlegm, diarrhea, diabetes, cholesterol-lowering, intestinal worms, acute rheumatism, ulcers, and hypertension. One of the causes of heart disease, atherosclerosis, and cancer is oxidative stress. The stress can be cured or reduced by taking antioxidant. Flavonoid, a phenol compound class, is one of the secondary plant metabolites that function as antioxidant. This paper determines total levels of phenol, flavonoid, and antioxidant activity of Alstonia *stem bark extract (Alstonia scholaris R. Br). Quantitative determination of total phenolics with the folin-ciocalteu method expressed as mg of gallic acid equivalent (GAE) per gram of extract, total flavonoids content by AlCl₃ method expressed as Quercetin equivalent (QE), and in vitro antioxidant activities with DPPH (2,2-diphenyl-1-picrylhydrazyl) method expressed in terms of IC₅₀ (inhibition concentration). Results show that extraction of three replicates in maceration with 96% ethanol yielded 4.19% filtrate. The total phenolic content was 51.50 mg GAE /g extract, while the total flavonoid content was 0.35 mg QE /g extract. IC₅₀ value of antioxidant activity assay of stem bark extract was 211.54 µg/mL.

Abstract

Cholesterol is a metabolite which contains sterol fat, which is important to support cell functions and generate vitamin D, cortisol and reproduction hormones. Higher cholesterol content known as hypercholesterolemia is a predisposing towards cardiovascular disease. Previous study reported that glucommanan and activated charcoal individually can lower cholesterol levels, however combination both of them for lowering the cholesterol level has not been studied intensively. This paper examines the ability of glucommannan derived from Amorphophallus flour and activated charcoal in reducing cholesterol level of Sprague Dawley rat. Firstly, glucommanan was isolated from Amorphophallus flour and activated charcoal was produced from teak sawdust and coconut fiber. Both component were formulated and characterized using Fourier Transform Infra Red (FTIR), x-ray diffractometer and scanning electron microscope. Thirty five adult male Sprague Dawley rat with body weight of 160 to 200 g were divided into seven treatment groups: high-fat diet (DTL) and glucommanan, DTL and teak's activated charcoal (TC), DTL and cocout fiber's activated charcoal (CC), DTL and glucommanan and CC (1:1), DTL and glucommanan and CC (2:1), DTL and glucommanan and CC (1:2) and DTL without treatment as control. Initial rat cholesterol level was measured and it was compared with those after five weeks. Results show that the greatest cholesterol reduction (37.4%) is recorded from rat with DTL and glucommanan and CC (1:1) and low density lipoprotein reduction by about 49.7% and triglyceride reduction by 18.3%.
