Unlocking the Potential of Agarwood Leaves: Phytochemical Screening, Tannin Levels, and Hedonic Tea Preferences in North Sumatra

Agarwood plants (Aquilaria malaccensis Lamk) are renowned for their high economic value, primarily due to the presence of secondary metabolite compounds, including antioxidants, in their leaves. This study aims to explore the potential of agarwood leaves, focusing on their chemical content, tannin levels, and community preference for agarwood leaf tea planted in two villages in North Sumatra Province.

Phytochemical Screening and Characterization of Agarwood Leaves

Phytochemical screening is a crucial step in identifying the chemical content of agarwood leaves. This study employed phytochemical screening methods to analyze the chemical composition of agarwood leaves from the villages of Asam Jawa Raya and Julu. The results revealed the presence of various secondary metabolite compounds, including flavonoids, tannins, alkaloids, glycosides, and triterpenoids.

In addition to phytochemical screening, the quality of agarwood leaves was assessed by determining their water content and conducting characterization tests. The results showed that the water content of agarwood leaves from both villages met the standard of no more than 10%. Characterization of Simplisia Gaharu leaves revealed differences in water-soluble juice, ethanol-soluble juice, total ash, and acid-soluble ash between the two villages. The village of Asam Jawa Raya had 13.84% water-soluble juice, 8.17% ethanol-soluble juice, total ash of 6.05%, and acid-soluble ash of 0.84%. In contrast, the village of Julu had 8.26% water-soluble juice, 5.57% ethanol-soluble juice, total ash of 6.81%, and acid-soluble ash of 0.87%.

Tannin Levels and Hedonic Tests of Agarwood Leaf Tea

Tannin levels in agarwood leaves were determined using the Lowenthal-Procter method. The results showed that tannin levels were not significantly different between the two villages, with values of 1.618% in Asam Jawa Raya and 1.656% in Julu.

To evaluate the community's preference for agarwood leaf tea, a hedonic test was conducted with aroma, flavor, and color parameters. The results showed that agarwood leaf tea from Asam Jawa Raya had a color and aroma that were classified as "quite like," but the taste was classified as "dislike." In contrast, agarwood leaf tea from Julu had aroma, taste, and color that were classified as "quite like."

Analysis and Implications

The results of this study highlight the potential of agarwood leaves as a source of antioxidants and raw materials for herbal tea. The presence of flavonoids, tannins, alkaloids, glycosides, and triterpenoids in agarwood leaves indicates high antioxidant potential. This study also suggests that differences in the characteristics of agarwood leaves between the two villages may be attributed to environmental factors and different cultivation methods. These differences, in turn, affect the level of community preference for agarwood leaf tea.

Suggestions and Development

This research opens opportunities for developing agarwood leaf tea as a product that is more attractive and accepted by the community. Suggestions for development include:

Development of Agarwood Leaf Tea Formulation: Combining agarwood leaves with other ingredients such as ginger, lemon, or honey can improve the taste and uniqueness of agarwood leaf tea.
Development of Processing Methods: Exploring the best processing method that can produce agarwood leaf tea with a preferred aroma, taste, and color.
Socialization and Education: Socialization and education to the public about the benefits and ways of processing agarwood leaf tea can increase public interest in this product.

The development of the potential of agarwood leaves as a high economic value commodity can improve the welfare of the community in agarwood-producing areas, while promoting the use of herbal plants for health.

Conclusion

This study demonstrates the potential of agarwood leaves as a source of antioxidants and raw materials for herbal tea. The results highlight the importance of phytochemical screening, tannin levels, and community preference in developing agarwood leaf tea as a product that is more attractive and accepted by the community. Further research is needed to explore the potential of agarwood leaves and to develop agarwood leaf tea as a product that can benefit the community and promote the use of herbal plants for health.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research should be conducted to explore the potential of agarwood leaves and to develop agarwood leaf tea as a product that is more attractive and accepted by the community.
The development of agarwood leaf tea formulation, processing methods, and socialization and education programs should be prioritized to promote the use of herbal plants for health.
The community in agarwood-producing areas should be involved in the development of agarwood leaf tea to ensure that their needs and preferences are met.

Limitations

This study has several limitations that should be acknowledged. Firstly, the study was conducted in only two villages in North Sumatra Province, which may limit the generalizability of the findings. Secondly, the study relied on a small sample size, which may not be representative of the larger community. Finally, the study did not explore the potential of agarwood leaves in other areas, such as medicine and cosmetics.

Future Directions

This study provides a foundation for further research on the potential of agarwood leaves and the development of agarwood leaf tea as a product that is more attractive and accepted by the community. Future studies should explore the following directions:

Exploring the potential of agarwood leaves in other areas, such as medicine and cosmetics.
Developing agarwood leaf tea formulation, processing methods, and socialization and education programs that are tailored to the needs and preferences of the community.
Conducting further research on the phytochemical screening, tannin levels, and community preference for agarwood leaf tea to ensure that the product meets the standards of quality and safety.

By addressing these limitations and exploring new directions, this study can contribute to the development of agarwood leaf tea as a product that is more attractive and accepted by the community, while promoting the use of herbal plants for health.
