Comprehensive Nutritional Breakdown of Emilia sonchifolia
Emilia sonchifolia, commonly known as lilac tasselflower, is an herbaceous plant found in tropical and subtropical regions that is valued for both its edibility and traditional medicinal uses. While its traditional applications are numerous, a clear understanding of its specific nutritional value is crucial for both consumers and health professionals. Research into this plant's nutritional and phytochemical profile reveals it to be a source of various beneficial compounds.
Macronutrient Profile
Several studies have analyzed the proximate composition of E. sonchifolia leaves, offering insights into its macronutrient content. The percentages and caloric values vary slightly based on the study methodology and preparation (e.g., fresh vs. dry weight), but a general profile can be established.
Based on fresh plant analysis, the composition per 100g is approximately:
- Moisture: 83.18%
- Carbohydrate: 7.042%
- Protein: 3.11%
- Crude Fiber: 2.84%
- Fat: 0.938%
- Ash: 2.84%
- Energy: 52.624 kcal
These values are comparable to popular edible greens like spinach, suggesting E. sonchifolia is a nourishing food source. When dried, the nutrient density significantly increases, as reflected in data from PFAF.org, which reports a much higher content of protein, fiber, and minerals per 100g.
Mineral Content
The mineral composition of E. sonchifolia is particularly impressive. The plant contains several essential macro- and micro-minerals that are vital for human health.
Macro-minerals per 100g:
- Calcium (Ca): 310 mg
- Potassium (K): 137 mg
- Magnesium (Mg): 119 mg
- Sodium (Na): 55 mg
Micro-minerals per 100g:
- Iron (Fe): 29 mg
- Manganese (Mn): 1.52 mg
- Zinc (Zn): 1.21 mg
- Copper (Cu): 0.17 mg
- Chromium (Cr): 0.20 mg
These findings suggest that E. sonchifolia can be an excellent dietary source for these essential minerals, potentially contributing to bone health, fluid balance, and various enzymatic functions.
Phytochemicals and Antioxidant Properties
Beyond the basic nutritional components, E. sonchifolia is rich in phytochemicals, which are non-nutrient plant compounds with potent health benefits.
Key phytochemicals include:
- Flavonoids: Studies have identified significant flavonoid content, including quercetin, kaempferol, and rutin, which are known for their antioxidant capabilities. Flavonoids help protect cells from oxidative damage caused by free radicals.
- Tannins: These compounds also contribute to the plant's antioxidant profile.
- Terpenoids: The n-hexane extract of E. sonchifolia has shown a high concentration of terpenoids, which are also associated with antioxidant activity.
- Other Bioactive Compounds: The plant contains other substances like alkaloids, saponins, and beta-sitosterol, though the concentration varies across different parts of the plant.
The antioxidant potential of E. sonchifolia has been confirmed through various in vitro assays, where extracts demonstrated significant free radical scavenging activity, comparable to standard antioxidants like ascorbic acid. This powerful antioxidant capacity is likely the basis for many of its traditional medicinal applications.
Comparison with Common Greens
To put the nutritional content into perspective, here's a comparison of fresh E. sonchifolia with fresh spinach (approximate values per 100g) based on the cited research.
| Nutrient | Emilia sonchifolia (Fresh, approx.) | Spinach (Fresh, typical) |
|---|---|---|
| Moisture | ~83.18% | 81.8–83.9% |
| Protein | ~3.11% | 4.1–4.8% |
| Fat | ~0.938% | 0.3–0.5% |
| Carbohydrate | ~7.042% | 4.3–5.2% |
| Energy | ~52.6 kcal | 47–51 kcal |
| Calcium | 310 mg | ~99 mg [Uncited, general knowledge] |
| Iron | 29 mg | ~2.7 mg [Uncited, general knowledge] |
This table highlights that while the basic macronutrient profile is somewhat similar, E. sonchifolia offers a notably higher concentration of certain minerals, like calcium and iron, making it a potentially superior source for these nutrients.
Important Safety Information
It is essential to note that while E. sonchifolia has a rich nutritional profile and traditional uses, it reportedly contains pyrrolizidine alkaloids. These compounds are considered potentially hepatotoxic, meaning they can cause liver damage, especially when consumed in large quantities or over a long period. For this reason, some sources recommend caution and further investigation into its toxicity before widespread adoption as a food or health supplement. Its traditional use and preparation methods might mitigate these risks, but it is not recommended for unsupervised, long-term consumption without further safety data. The presence of these alkaloids is a crucial factor to consider alongside its nutritional benefits.
Conclusion
In summary, Emilia sonchifolia is a nutritious plant, offering a respectable amount of protein, fiber, and carbohydrates, along with a dense concentration of essential macro- and micro-minerals. Its rich phytochemical content, particularly flavonoids and terpenoids, contributes to its significant antioxidant and other medicinal properties, which aligns with its long history in ethnomedicine. However, the presence of potentially hepatotoxic pyrrolizidine alkaloids requires careful consideration, and further research is warranted to ensure its safe consumption. Anyone considering its use should approach with caution and consult with a healthcare professional, especially concerning dosage and preparation methods, as traditional preparation may play a role in safety.
