Abstract

Background: Antioxidants are compounds that prevent an oxidation reaction from free radical compounds and important role in capturing free radicals in the human body. Excessive free radicals in the body can cause tissue damage and degenerative diseases. Pandanus amarillyfolius are known to act as natural antioxidant that have the potential to capture free radical compounds, because of their presence of flavonoid compounds. Objective: This study aims to determine the free radical scavenging activity of DPPH against the leaf extract of Pandanus amaryllifolius. Method: Pandanus amaryllifolius extraction was carried out using the maceration method with methanol as solvent (1:10). Concentration was carried out using a rotary evaporator to obtain a thick extract. Phytochemical screening and TLC test were carried out qualitatively using the mobile phase n-butanol: acetic acid: water (6:2:2) and phytochemical testing including flavonoids, alkaloids, saponins, tannins, steroids or terpenoids to determine the presence of flavonoid compounds as antioxidants. Free radical scavenging activity was tested using DPPH free radical scavenger with concentrations of vitamin C 2, 4, 5, 6, 8 ppm and pandanus fragrance extract concentrations of 10, 15, 20, 25 ppm and measured using a UV-Vis spectrophotometer to calculate the IC50 value. Result: The results of the phytochemical screening test of fragrant pandan indicate the presence of flavonoid compounds. The Rf value of the TLC test obtained 0.765 quarcetin and 0.787 extract and the resulting yellow spots, the Rf value of pandan extract which was almost the same as the Rf value of quercetin indicated that the pandan extract may contain the same compounds as quercetin, namely flavonoid compounds. The results of the free radical scavenging activity of methanol extract of pandan leaves were 86,861 g/ml and for comparison, vitamin C was 39,103 g/ml. Based on the statistical analysis of the T-Test, it is known that there is a difference between the sample and the standard with a significant value (p <0.05), namely 0.001 and 0.023. Conclusion: The Pandanus amaryllifolius extract test using the DPPH method is in the strong category (IC50 <50 -100 g/ml) and the comparison of Vitamin C is in the very strong category (IC50 <50 g/ml).

Abstract

Bauhinia purpurea L. is an ornamental plant that is not widely known or explored by the public, despite its significant antioxidant properties. Phenolic compounds and flavonoids, known for their antioxidant activity, can be extracted from the leaves through maceration with 70% ethanol and 96% ethanol. The difference in solvent polarity between these two ethanol concentrations affects the solubility of bioactive compounds. This study aimed to evaluate the effect of 70% and 96% ethanol concentrations Bauhinia purpurea L on the total phenolic and flavonoid levels in. An experimental method was employed, using Bauhinia purpurea L powder macerated with 70% and 96% ethanol, followed by evaporation at 40°C-50°C to obtain thick extracts. The extracts were subjected to organoleptic tests, phytochemical screening, Thin Layer Chromatography (TLC), and UV-Vis spectrophotometry. Total phenolic content was determined using gallic acid standards (mg GAE/g extract), while total flavonoid content was measured using quercetin standards (mg QE/g extract). The organoleptic test revealed that both the 70% and 96% ethanol extracts of Bauhinia purpurea L had a blackish-green color, thick consistency, distinctive odor, and bland taste. Phytochemical screening indicated the presence of phenolics, flavonoids, and saponins. The total phenolic content for the 70% ethanol extract was 14.644 ± 0.222 mg GAE/g, and the total flavonoid content was 25.519 ± 0.921 mg QE/g. The total phenolic content for the 96% ethanol extract was 7.176 ± 0.347 mg GAE/g, and the total flavonoid content was 11.208 ± 0.412 mg QE/g. These results indicate a significant difference between the use of 70% and 96% ethanol in extracting total phenolic and flavonoid content from Bauhinia purpurea L, with the 70% ethanol extract showing higher levels of both compounds.

Abstract

West Lampung Robusta coffee has a higher caffeine content than other types of coffee. The variations in extraction time in ultrasound-assisted extraction (UAE) produced different caffeine contents than conventional extraction methods. This study aims to determine extraction time variation (15, 30, 45) influences caffeine contents in roasted coffee beans. The organoleptic test and alkaloid test evaluated Robusta coffee qualitatively. The extract obtained was measured by measuring the % MC, yield value, and wavelength scanning. Quantitative analysis using UV-Vis Spectrophotometry determined the caffeine content with different extraction times, and then each group was assessed using SPSS software. The coffee bean powder was dark brown, had a distinctive coffee aroma, bitter taste, and smooth texture, and contained alkaloids with the Mayer, Wagner, and Dragendorff tests. The yield and % water content of extract at 30 (36.938%; 6.39%) were higher than at 15 (24.111%; 6.07%) and 45 minutes (22.170%; 6.37%). Alkaloids of the extract were investigated at a wavelength of 273 nm. Caffeine contents were 0.977 ± 0.018 mgCE/mg at the 15, 0.792 ± 0.054 mgCE/mg at the 30, and 0.979 ± 0.026 mgCE/mg at the 45 minutes in significant (P<0.05). In conclusion, the difference in extraction time impacted the caffeine content of the robusta coffee bean.
