Abstract

Singkil leaves (Premna corymbose Roxb & Willd.) are a plant that is widely found in Kalimantan, and usually grows in the yard of houses or plantations. A research on phytochemicals screening and antioxidant activity test of singkil leaves (Premna corymbose Roxb & Willd.) using DPPH (1,1- diphenyl-2-picrylhydrazyl) method had been conducted. Test for alkaloids, triterpenoids/steroids, phenolic, flavonoids, saponins, and quinone were included in phytochemical screening. The results of the literature show that the methanol extract exhibits antioxidant activity in the strong category, which has an IC50 value of 20.66 μg/ml. Methanol extract of singkil leaves (Premna corymbose Roxb & Willd.) has potential as an antioxidant. Keywords: Singkil leaves (Premna cordifolia Roxb.), phytochemical screening, antioxidant, DPPH

Abstract

Singkil leaves (Premna cordifolia Roxb.) are a plant that is widely found in Kalimantan, and usually grows in the yard of houses or plantations. The antioxidant activity test of methanol extract from Singkil leaves (Premna cordifolia Roxb.) has been done. This research aims to determine the antioxidant properties of methanol extract from leaves. Based on the results of the phytochemical test, it is known that the methanol extract contains alkaloids, flavonoids, phenolics, steroids and triterpenoids. The results of the literature show that the methanol extract exhibits antioxidant activity in the "Strong" category, which has an IC50 value of 77.46 mg/L. Methanol extract of singkil leaves (Premna cordifolia Roxb.) has potential as an antioxidant. Keywords : Singkil leaves (Premna cordifolia Roxb.), antioxidant, DPPH

Abstract

Bajakah (Uncaria cordata (Lour.) Merr.) is an endemic plant to Kalimantan which is widely used as medicine. Various studies have been conducted regarding the phytochemical content and biological activity of Bajakah. Phytochemical screening was carried out for the content of alkaloids, flavonoids, polyphenols, triterpenoids, steroids, saponins, and tannins. Literature studies show that Bajakah has antioxidant activity within ethanol fraction with a very strong capacity as indicated by an IC50 value of 49.22 ppm, within the nhexane fraction with a medium capacity as indicated by an IC50 value of 108.22 ppm, and within ethyl acetate fraction with a medium capacity as indicated by an IC50 value of 130.30 ppm. Bajakah is also known to have antihyperuricemia activity by reducing uric acid levels at extract doses of 5.3 mg/30gBW, 10.6 mg/30gBW, and 21.2 mg/30gBW. Anticholesterol activity was indicated by reducing cholesterol levels at extract doses of 5.3 mg/30grW (11.45%), 10.2 mg/30grW (12.89%), and 21.2 mg/30grW (21.05%). Antiinflammatory activity was showed by testing the ethyl acetate extract of Bajakah stem at doses of 200 and 400 mg/kgBW. The acute toxicity test showed an LD50 value of >5000 mg/kgBW; indicating that the butanol fraction of Bajakah is relatively harmless and has potential as a standardized herbal medicine (OHT). Keywords : Uncaria cordata (Lour.) Merr.), phytochemical screening, bioassay

Abstract

Malic acid (2-hydrobutanedioic-acid) is a dicarboxylic acid (carboxylic acid) which is generally found in many apples. Several malic acid derivatives have been synthesized through esterification and amidation reactions, including methyl malate, maleyl oleate and maleyl glutamide. Based on the results of FT-IR analysis of malic acid, it is known that there is an absorption peak at wave number 3448.72 cm¬-1 indicating the presence of an alcohol group and an absorption peak at wave number 1720.50 cm-1 indicating the presence of a carboxylic group. In methyl malate, it is known that in the wave number area of ​​1735.93 cm-1, stretching vibrations of the C=O ester carbonyl group occur. In maleyl oleate, the absorption in the wave area of ​​1743.65 cm-1 is a typical absorption from the stretching vibration of C=O ester. In maleyl glutamide, it is known that there is absorption at the peak wave number of 3425.58 cm-1 which is the stretching vibration of the NH (amide) group. The results of several literatures explain that the malic acid derivative, namely methyl malate, has an HLB value of 11.2 and can be used as an O/W (Oil in Water) emulsifier. The HLB value of maleyl oleate has a value of 4.61 which can be used as a W/O (Water in Oil) emulsifier and for maleyl glutamide the HLB is 14.84 which can be used as an O/W (Oil in Water) emulsifier. Therefore, malic acid derivatives have potential as materials for surfactant synthesis. Keywords: Malic Acid, Esterification and HLB (Hydrophilic Lipophilic Balance).
