The presence of Zinnia elegans in the Tambakaji area has so far been viewed primarily from an aesthetic perspective, despite its biological potential through secondary metabolite content that requires further investigation. This study critically determines the localization of secondary metabolite compounds in various plant organs to map the pharmacological capacity of the species. The study was conducted using a qualitative descriptive approach with fresh preparation techniques and specific reagents. The observation results showed an organ-specific distribution of secondary metabolite; alkaloids, phenols, and tannins were strongly identified in root and stem tissues, while flavonoids and lipids were not detected in any organ. These findings indicate that the distribution of secondary metabolite in Zinnia elegans is not evenly spread across all organs. This study provides fundamental information for the utilization of Zinnia elegans as a source of natural bioactive raw materials and serves as an important reference for the development of its pharmacological potential.
