Nutritional Value of Tabernaemontana pachysiphon (Smoothfruit Cornettree)
1. Protein: The leaves of Tabernaemontana pachysiphon contain trace amounts of protein, supporting tissue repair and enzymatic functions. While not a primary source, proteins contribute to its role in traditional medicinal preparations where the plant is used in small quantities.
2. Carbohydrates: The seeds and fruits likely provide carbohydrates, primarily in the form of starches and minor sugars, offering a potential energy source. However, their nutritional value is limited due to the plant’s toxicity and primary use in medicine rather than as food.
3. Fiber: Dietary fiber is expected in the leaves and fruits, aiding digestion and promoting gut health. Fiber content supports its traditional use as a styptic, though exact quantities are not well-documented.
4. Alkaloids: The plant is rich in indole alkaloids like apparicine, voacangine, and tubotaiwine, which are bioactive compounds rather than nutrients. These may influence metabolic processes but are toxic in high doses, limiting nutritional applications.
5. Phenolic Compounds: Phenolics, such as those identified in related Tabernaemontana species, act as antioxidants in T. pachysiphon, potentially reducing oxidative stress and supporting cellular health when used medicinally.
6. Flavonoids: Flavonoids are present in the leaves, offering anti-inflammatory and antioxidant benefits. These compounds enhance the plant’s pharmacological value but are secondary to nutrition.
7. Minerals (Potassium): Trace potassium may be found in the leaves, supporting electrolyte balance and nerve function, inferred from studies on alkaloid-rich Apocynaceae plants.
8. Minerals (Calcium): Calcium is likely present in small amounts, contributing to bone health, though the plant’s latex and alkaloids may interfere with absorption.
9. Vitamins: Small amounts of vitamins, such as vitamin C, may be in the fresh leaves, supporting immune function, based on patterns in Tabernaemontana species.
10. Lipids: The seeds contain minor lipids, providing energy, but their content is low and overshadowed by the plant’s medicinal alkaloids.
The nutritional profile of Tabernaemontana pachysiphon is modest and not well-studied, with its value primarily in bioactive compounds like alkaloids rather than as a food source. Due to toxicity from latex and alkaloids, it is not recommended for direct consumption without processing, and its use is mainly traditional and medicinal.
