Nutritional Value of Strophanthus preussii (Preuss’s Strophanthus)
1. Cardiac Glycosides: Strophanthus preussii seeds contain cardiac glycosides like periplocin and periplocymarin, which are based on the aglycone periplogenin, supporting heart function by increasing contractility but requiring extreme caution due to toxicity.
2. Alkaloids: The plant’s seeds and bark include toxic alkaloids, which contribute to antimicrobial properties and traditional uses for infections, though they pose significant risks if ingested improperly.
3. Saponins: Present in the seeds, saponins provide potential immune-boosting and foaming properties, aiding in traditional wound healing applications.
4. Flavonoids: Trace flavonoids in the leaves and stems act as antioxidants, helping to reduce oxidative stress and inflammation in limited traditional preparations.
5. Phenolic Compounds: These compounds in the plant parts enhance antioxidant capacity, potentially protecting cells from damage in external uses like sore treatment.
6. Tannins: Found in the bark, tannins offer astringent effects that support wound healing and reduce inflammation in topical applications.
7. Terpenoids: Minor terpenoids contribute to antimicrobial activities, aligning with ethnobotanical uses for gonorrhea treatment.
8. Carbohydrates: The seeds contain carbohydrates as a minor energy source, though the plant is not used as food due to toxicity.
9. Sterols: Plant sterols may support cholesterol regulation in theoretical terms, but practical use is limited by the plant’s poisonous nature.
10. Glycosides (Strophanthidin-based): Small amounts of strophanthidin-based glycosides provide additional cardiac stimulant effects, similar to digitalis but with higher toxicity risks.
Strophanthus preussii is highly toxic and not suitable as a nutritional source; its components are primarily bioactive for medicinal or poisonous purposes, with seeds used in arrow poisons and low-dose extracts for heart conditions in traditional contexts, but modern use requires professional supervision.
Scientific Evidence and Case Studies on Strophanthus preussii (Preuss’s Strophanthus)
1. Włodarczyk et al. (2022): This study conducted fingerprinting, isolation, and identification of saponins in various Strophanthus seeds, including S. preussii, revealing high saponin content (up to 5% in seeds) with potential antimicrobial and anti-inflammatory benefits, supporting traditional wound healing uses (Włodarczyk, M., & Gleńsk, M., 2022).
2. Orhan et al.
