Voacanga africana (Voacanga)

Voacanga africana is a medicinal plant rather than a dietary food source, so conventional macronutrient profiling is limited. Its significance lies primarily in its alkaloid content. Bioactive alkaloids: voacangine (primary alkaloid, ~0.5–2% dry weight of bark/seeds), voacamine (~0.3–1.2% dry weight), tabersonine (~0.1–0.8%), ibogaine precursors including voacristine and coronaridine (~0.1–0.5% combined). Seeds contain the highest alkaloid concentration compared to bark and roots. Lipid content: seeds contain approximately 20–35% fixed oils, including oleic acid, palmitic acid, and stearic acid. Crude protein content in seeds is approximately 15–22% dry weight. Fiber content: approximately 8–12% crude fiber in seed meal. Micronutrients: modest levels of potassium (~300–500 mg/100g dry weight), calcium (~150–250 mg/100g), magnesium (~80–120 mg/100g), and trace iron (~3–6 mg/100g). Phytosterols including beta-sitosterol are present in the lipid fraction. Terpene indole alkaloids are the primary bioactive compounds responsible for pharmacological effects. Bioavailability notes: alkaloids are readily absorbed through the gastrointestinal tract; fat-soluble compounds benefit from co-ingestion with dietary lipids; alkaloid concentrations vary significantly by geographic origin, plant part, and extraction method.
