Abstract

Antioxidants are compounds that are able to ward off or reduce free radicals in the body so that they can prevent several diseases. Soursop leaves (Annona muricata L.) are used as a traditional herbal medicine to prevent or treat cancer, as well as a natural antioxidant, which is usually used by people by boiling it. The purpose of this study was to look at the phytochemical screening by comparing fresh boiled water, fresh juice, and a fresh extract of soursop leaves, as well as test the antioxidant activity with the addition of DPPH (1,1-diphenyl-2-picrylhydrazyl) and measured using a UV-Vis spectrophotometer at 516 nm. The results of the soursop leaf phytochemical screening showed that there were groups of chemical compounds such as flavonoids, glycosides, tannins, and saponins. The results of testing the antioxidant activity by looking at the maximum wavelength of DPPH, using a UV-Vis spectrophotometer, obtained IC50 values for fresh juice of 770.067 µg/mL, fresh decoction of 1,022.8422 µg/mL, and ethanol extract of 299.733 µg/mL. Based on the results of the study, it was shown that the ethanol extract had stronger antioxidant activity than a fresh decoction and the fresh juice of soursop leaves.

Abstract

Tomato (Solanum lycopersicum L.) is one of the most widely consumed fruits and vegetables due to its nutritional value and health benefits. This study aimed to determine the vitamin C, glucose, and crude fiber contents in different tomato varieties, namely red, yellow, green, and cherry tomatoes. The analysis included phytochemical screening, qualitative tests, and quantitative determination. Phytochemical screening was performed to identify the presence of secondary metabolites, while qualitative tests were conducted to confirm the presence of vitamin C and glucose. Quantitative analysis of vitamin C and glucose was carried out using the UV–Vis spectrophotometric method, whereas crude fiber content was determined using the gravimetric method. The results showed that flavonoids, alkaloids, and saponins were present in all tomato samples, while glycosides and tannins were detected only in certain varieties, and steroids/triterpenoids were not detected. Quantitative analysis indicated that the highest vitamin C content was found in red tomatoes (21.62 ± 0.178 µg/100 g), followed by cherry tomatoes (18.78 ± 0.002 µg/100 g), yellow tomatoes (18.38 ± 1.038 µg/100 g), and green tomatoes (12.20 ± 2.287 µg/100 g). The glucose content was 39.2 ± 0 µg/100 g in red tomatoes and 34.53 ± 0.597 µg/100 g in green tomatoes. Meanwhile, the crude fiber analysis showed the highest content in yellow tomatoes (53.44%), followed by cherry tomatoes (48.10%), red tomatoes (42.05%), and green tomatoes (40.37%). These findings indicate that different tomato varieties possess distinct nutritional profiles, and tomatoes can be considered a valuable dietary source of vitamin C, natural sugars, and dietary fiber that may contribute to maintaining human health.

Abstract

Background: Kunir asem herbal medicine is a traditional beverage widely consumed by the community to relieve menstrual pain due to the content of turmeric (Curcuma domestica Val.) which contains active compounds with analgesic, antipyretic, and anti-inflammatory properties. However, information regarding curcuminoid levels in powdered herbal medicine products circulating in the community remains limited, particularly in Medan City. Objective: This study aimed to identify the presence of curcuminoids in powdered herbal medicine containing turmeric rhizome circulating in Medan City and to determine the compliance of their levels with quality requirements according to the Indonesian Herbal Pharmacopoeia Second Edition 2017. Methods: A total of 10 samples of powdered herbal medicine containing turmeric rhizome were collected from five sub-districts in Medan City (Medan Johor, Patumbak, Deli Tua, Medan Baru, and Medan Polonia) using simple random sampling technique. Sample extraction was carried out by maceration using 96% ethanol solvent. Qualitative analysis of curcuminoids was performed using Thin Layer Chromatography (TLC) method with chloroform:methanol (95:5) as mobile phase and curcumin standard as comparison. Determination of curcuminoid levels was conducted using UV-Vis Spectrophotometry method at a maximum wavelength of 425 nm. Results: Qualitative analysis results showed that all samples were positive for curcuminoids, indicated by Rf values close to or equal to the Rf value of curcumin standard (0.78), ranging from 0.76-0.82. The quantitative analysis results showed that among the ten samples tested, three samples (SJ-A 0.66%, SJ-B 0.29%, and SJ-I 0.28%) had curcuminoid levels below the minimum requirement, while seven other samples (SJ-C 5.73%, SJ-D 7.50%, SJ-E 9.13%, SJ-F 5.94%, SJ-G 4.66%, SJ-H 8.02%, and SJ-J 6.07%) met the requirements. Conclusion: All samples of powdered herbal medicine containing turmeric rhizome circulating in Medan City were positive for curcuminoids; however, three out of ten samples (30%) did not meet the quality requirements for curcuminoid levels according to the Indonesian Herbal Pharmacopoeia Second Edition 2017, which specifies not less than 3.82%. This indicates the need for more stringent quality control of herbal medicine products circulating in the community.
