Background and Significance of Coriander Leaves

Indonesia is a country rich in various types of plants, both used as medicine and as food ingredients. Among these plants, coriander leaves (Coriandrum sativum L.) stand out as a potential herbal medicine and nutritious food ingredient. Coriander leaves are known to contain flavonoid compounds, which have been proven to have antioxidant properties. This makes consumption of coriander leaves believed to provide numerous health benefits. The use of coriander leaves as a spice in cooking is well-known, but its potential as a natural source of antioxidants has not been fully explored.

Objective of the Study

This study aims to determine the total levels of phenol and total flavonoids in coriander leaf extract processed using 96% ethanol solvent and ethyl acetate. In addition, this research also wants to evaluate the antioxidant activity of coriander leaf extract. The determination of total phenol and total flavonoid content is crucial in understanding the chemical composition of coriander leaves and its potential health benefits. The evaluation of antioxidant activity is also essential in assessing the effectiveness of coriander leaves as a natural source of antioxidants.

Methodology of the Study

This research was conducted with an experimental approach consisting of several stages, including sample preparation, phytochemical screening, simplicia characterization, and the manufacture of coriander leaf extract. The extraction process was carried out by the maceration method, where simplicia was extracted using two types of solvents, namely 96% ethanol and ethyl acetate, which have different polarities. The use of two solvents with different polarities allows for the extraction of a wider range of compounds, including phenols and flavonoids.

Phytochemical Screening and Characterization

Phytochemical screening was conducted to identify the presence of various compounds in coriander leaves, including phenols and flavonoids. The results of phytochemical screening showed the presence of various compounds, including flavonoids, phenolic acids, and terpenoids. The characterization of simplicia was also conducted to determine the physical and chemical properties of coriander leaves.

Extraction and Analysis of Total Phenol and Total Flavonoid Content

The total phenol level was determined using the Folin-Ciocalteau method, while the total flavonoid level was measured by the colorimetric method using AlCl3 reagent. The antioxidant activity of coriander leaf extract was tested by the DPPH free radicals (1,1-diphenyl-2-Picrylhydrazil) and the results were measured using the UV-Visible spectrophotometer. The use of DPPH free radicals allows for the evaluation of the antioxidant activity of coriander leaves in a controlled environment.

Results of the Study

The results show that the highest level of phenol and total flavonoids found in ethanol extract of coriander leaves. The total phenol content obtained is 30.7049 mg GAE/g of the extract and total flavonoid level of 51,4410 mg QE/g extract. The highest antioxidant activity is also measured in ethanol extract, with an IC50 value of 91,4867 μg/ml, shows a strong potential in reducing free radicals.

Conclusion and Implications

From the results of the study, it can be concluded that ethanol extract from coriander leaves has a higher level of total phenol and total flavonoids compared to extracts that use ethyl acetate. In addition, high antioxidant activity from ethanol extract shows that coriander leaves have the potential as a strong natural source of antioxidants. This study not only provides important information about the chemical components in coriander leaves, but also shows the relevance of the use of this plant in the context of health and nutrition for the community.

The Importance of this Research

The importance of this study lies in the added value that can be obtained from coriander leaves as a natural ingredient that functions not only as a spice in cooking but also as a source of antioxidants. In the midst of increasing trends in the use of natural products in the field of health and food, the results of this study can be a useful reference for further development in the health and food industry.

Future Directions

This study provides a foundation for further research on the potential health benefits of coriander leaves. Future studies can focus on the isolation and characterization of specific compounds in coriander leaves, as well as the evaluation of the antioxidant activity of coriander leaves in various biological systems. Additionally, the development of coriander leaf-based products, such as supplements and functional foods, can be explored as a potential application of the results of this study.

Conclusion

In conclusion, this study provides important information about the chemical composition of coriander leaves and its potential health benefits. The results of this study show that coriander leaves have a high level of total phenol and total flavonoids, as well as high antioxidant activity. This study highlights the potential of coriander leaves as a natural source of antioxidants and provides a foundation for further research on the potential health benefits of this plant.
