Abstract

Free radicals are atoms or molecules, having one or more unpaired electrons. Increased production of free radicals can cause oxidative stress and cause many pathological conditions, e.g. cancers, heart diseases, and other diseases. The antioxidant can inhibit oxidative stress. Kalangkala (Litsea angulata) usually found in the South Kalimantan that can be used as an antioxidant. The study aimed to determine the antioxidant activity of ethanolic extract of Kalangkala fruits and seeds from South Kalimantan. Antioxidant activity was conducted qualitatively and quantitative uses the method DPPH. The result of the antioxidant activity of ethanolic extract of Kalangkala fruits and seeds qualitatively showed the presence of yellow spots on a purple background at Thin Layer Chromatography (TLC). The result of the activity of ethanolic extract of Kalangkala seeds quantitatively obtained IC50 value was 48.78 ppm and activity of ethanolic extract of Kalangkala fruits quantitatively obtained IC50 value was 243.14 ppm. Ethanolic extract of Kalangkala fruits and seeds from South Kalimantan has antioxidant activity.

Abstract

Free radicals are highly reactive compounds because they have unpaired electrons so that they can interact with body cell molecules, this can cause various diseases. Antioxidants are compounds that can ward off free radicals. Plants of the genus Mangifera are known to have antioxidant activity, one of which is Mangifera rufocostata Kosterm, a typical plant of South Kalimantan known as tandui. The purpose of this study was to determine the antioxidant activity of the methanol extract of the leaves of tandui (Mangifera rufocostata Kosterm.) using the DPPH test method. Phytochemical screening and antioxidant activity tests were performed using a UV-Vis spectrophotometer. The compounds contained in the methanol extract of tandui leaves (Mangifera rufocostata Kosterm.) are phenols, flavonoids, and tannins. The IC50 value of quercetin obtained was 2.39 ppm and the IC50 value of the tandui leaf methanol extract (Mangifera rufocostata Kosterm.) which was obtained was 8.222 ppm. Tandui leaf methanol extract has very strong antioxidant activity.

Abstract

Tigaron leaf methanol extract (Crateva religiosa) was reported to have activity as a very strong antioxidant. Differences in solvents in extracts can affect the results of pharmacological activity, for example, ethyl acetate solvent on antioxidant activity, so the purpose of this study was to determine the results of phytochemical screening and antioxidant activity of the ethyl acetate extract of Tigaron leaves (Crateva religiosa). Phytochemical screening was carried out qualitatively, while antioxidant activity was carried out quantitatively using the DPPH (2,2-Diphenyl-1-picrylhydrazyl) method using a UV-Vis spectrophotometer and quercetin comparator. The ethyl acetate extract of Tigaron leaves (Crateva religiosa) was extracted by maceration method. Phytochemical screening tests obtained positive results for the alkaloids, flavonoids, and steroids. Antioxidant testing using the comparator quercetin obtained IC50 results of 3.4384 ppm and the ethyl acetate extract of Tigaron (Crateva religiosa) leaves obtained IC50 results of 114.0457 ppm. It can be concluded that the ethyl acetate extract of Tigaron leaves (Crateva religiosa) has moderate potential as an antioxidant.

Abstract

Brazilian Spinach (Althernanthera sisso) leaves are known to have a high natural antioxidant activity content of 3.7 ppm. Antioxidants have an important role in the human body to prevent damage caused by free radicals. One of the compounds that have antioxidant activity is flavonoids. Based on this description, it is necessary to know the content of total flavonoids in A. sisso This study aims to determine qualitatively using Thin Layer Chromatography (TLC), while quantitatively using UV-Vis spectrophotometry. Maceration method with 70% ethanol solvent was used to extract Brazilian spinach leaves. Thin Layer Chromatography (TLC) followed by spray reagents was used to test the flavonoid compounds. Quercetin reagent was used to determine total flavonoid levels, while AlCl3 was used to determine total flavonoid levels. The results of this qualitative test showed the presence of flavonoids, and in the quantitative test using UV-Vis spectrophotometry the total levels of flavonoids were 70.890 ± 1.723% w/w quercetin equivalent. The 70% ethanol extract of A. sisso leaves contains flavonoids so that it has the potential to be developed as a medicinal plant
