Abstract

Piper acre Blume, known as Black Betel (local name), is a plant that is widely used by the people of East Kalimantan, especially in Samarinda, for the treatment of illness. Leaves (3-4 months old) are collected from Samarinda, extracted, fractionated, and monitored by DPPH antiradical activity. The isolation of the Piper acre Blume is performed on the active fraction, and the structure identification is based on spectroscopic data of the compound.  The leaves were dried, pulverized, and macerated with MeOH. Dried MeOH extract was obtained upon evaporation of the solvent. The extract was then fractionated by vacuum liquid chromatography (vlc), eluted gradually by solvents having different polarities (n-hexane, ethyl acetate and methanol). The fractions obtained were monitored using TLC [n-hexane: ethyl acetate (3: 1 v/v)] that was visualized by UV254 nm, UV366 nm and DPPH. The isolation was performed by preparative TLC [SiO2, n-hexane: ethyl acetate (3: 1)] on ethyl acetate fraction that showed the highest DPPH antiradical value. A single compound was obtained, and it appeared as a round spot and pure according to TLC performances at 3 different solvent systems. The isolated Piper acre Blume compound displayed the IC50 value on the anti-radical DPPH (measured at λ 520 nm) as 10.41µg/mL. The IR spectrum (KBr) showed –OH band (3450 cm-1), aliphatic bands [alkene, 3010 cm-1; alkana 2900 cm-1), an aromatic overtone bands (1900-200 cm-1) and a strong C=O band (1725 cm-1). The NMR (1H- and 13C-) (mono and 2D) indicated the present of a p-di-substituted aromatic signals (δ, 7.54 and 7.52, d, J =6 Hz, 1 H each), 2 methyl (δ, 0.96, d, J = 7.0 Hz, 6 Hs), a triplet signal (δ, 4.22 ppm). Other signals of CH- and CH2 were shown as m signals at δ, 1.64 and 1.34 ppm.  Based on those data, the compound was identified as isoamyl p-OH benzoate that is grouped as parabens used as a preservative in the pharmaceutical preparations. In conclusion, the anti-radical (DPPH) active compound present in the leaves of Piper acre Blume is identified as isoamyl p-OH benzoate, having IC50 value anti-radical DPPH 10,41µg/mL.

Abstract

Penggugut (Knema pallens W.J. deWilde) is an endemic plant from Kalimantan belongs to Myristicaceae or the nutmeg family. Penggugut can be found in habitats like lowland forest, sandy forests and mangroves. The efficacy and activity of penggugut especially the leaves, have not been widely known or studied. So that make the purpose was to know about the percentage yield of extract and fraction from penggugut leaves and to know the activity of Radical Scavenging DPPH from penggugut leaves. The methods used include extraction, liquid-liquid fractination and TLC by spraying DPPH. The results there are percentage of yield : methanol extract is 8,04%, n-hexane fraction is 28,9%, ethyl acetate fraction is 7,83% and n-butanol fraction is 9,8%. In the qualitative test, it was found that the spots have activity of Radical Scavenging were marked with yellow spots on a purple background, there are in the methanol extract have 4 spots with Rf values (0,07; 0,14; 0,29; 0,43), the n-hexane fraction have 3 spots with Rf values ??(0,1; 0,21; 0,43), the ethyl acetate fraction have 5 spots with Rf values ??(0,07; 0,17; 0,29; 0,43; 0,53) and the n-butanol fraction did not get any spots.

Abstract

Indonesia is a country with abundant natural wealth and almost all types of plants can grow in the territory of this country. One of them is oil palm leaf (Elaeis guineenis Jacq.) containing terpenoid compounds, steroids, alkaloids, flavonoids, glycosides, tannins and saponins and also this plant among the community has benefits that can be used for the treatment of skin infections. Purpose of this study was to determine the yield obtained as well as the antioxidant activity of ethanol extract of oil palm leaves. Oil palm leaves were extracted using 96% ethanol as solvents and using the maceration method. Testing the antioxidant activity of the ethanol extract of oil palm leaves was carried out using the DPPH method (2,2-diphenyl-1-picrylhydrazyl), where the absorbance was measured at max 515 nm using a UV-vis spectrophotometer. The results showed that the yield of oil palm leaf ethanol extract obtained as much as 5.44 % and obtained that the ethanolic extract of oil palm leaves had antioxidant activity against DPPH radicals with an IC50 value of 133.58 ppm. It could be concluded that the ethanolic extract of oil palm leaves (Elaeis guineensis Jacq.) had antioxidant activity in the moderate category because the IC50 value was between 100- 150 ppm.

Abstract

Ischemic stroke occurs due to obstruction of the blood vessels that supply the brain. Obstruction occurs due to increased fat lining the blood vessels or atherosclerosis. Atherosclerosis will cause cerebral thrombosis and cerebral embolism. This study aims to examine effectiveness of the use of drugs in ischemic stroke patients hospitalization at Nunukan Hospital. This study is a non-experimental study with a descriptive analysis design using medical record data collected retrospectively and the number of samples in this study was 70 patients. The sample selection of this research was using purposive sampling technique. The results showed tthe highest characteristics of ischemic stroke patients by gender were male (54.29%), based on age group 45-65 years (64.29%), based on diagnoses with comorbidities (64.70%), and the length of treatment the most occurred in 5-10 days (72.55%). The most used drugs single therapy for ischemic stroke are antiplatelet drugs, namely aspirin (28.57%) and the most used combination therapy is piracetam and citicoline (50%). The most frequent drug interactions were aspirin and clopidogrel (48.57%). While the accuracy of drug use includes the right indication (100%), the right drug (94.29%), the right dose (97.14%), and the right frequency (97.14%). Thus, it was concluded that the treatment of ischemic stroke at the inpatient installation the Nunukan General Hospital was effective.
