Purpose of the Study:

• To isolate and characterize secondary metabolites from the leaves of Rapanea myricoides.
• To identify and elucidate the structure of novel diprenylated benzoic acids.
• To contribute to the knowledge of the chemical diversity within the Rapanea genus.

Main Methods:

• Extraction and isolation of compounds from plant material.
• Spectroscopic data analysis (NMR, MS) for structural elucidation.
• Synthesis of simpler analogues for structural comparison and confirmation.

Main Results:

• Isolation of a known diprenylated benzoic acid derivative (1).
• Identification and structural assignment of a new diol, myricoidiol (2).
• Characterization of compound 2 as 3-(2",3"-dihydroxy-3",7"-dimethyloct-6"-enyl)-4-hydroxy-5-(3'",3"'-dimethylallyl)benzoic acid.

Conclusions:

• The leaves of Rapanea myricoides contain unique diprenylated benzoic acid derivatives.
• Myricoidiol represents a novel chemical structure with potential for further investigation.
• The study expands the understanding of Rapanea myricoides phytochemistry and natural product diversity.
