Nutritional Value of Dichroa (Dichroa febrifuga)
1. Febrifugine: This quinazolinone alkaloid is a primary bioactive compound in Dichroa febrifuga roots, known for its antimalarial properties, but it also contributes to potential anti-inflammatory effects by modulating immune responses.
2. Isofebrifugine: An isomer of febrifugine, this alkaloid supports antimicrobial activity and may aid in reducing parasitic infections, though its role in nutrition is limited due to toxicity concerns.
3. Flavonoids: Present in the leaves and roots, flavonoids act as antioxidants, helping to neutralize free radicals and potentially supporting cellular health and reducing oxidative stress.
4. Terpenoids: Compounds like isoarborinol in the leaves provide anti-inflammatory benefits, contributing to the plant’s traditional use in managing inflammation and related conditions.
5. Phenolic Compounds: These antioxidants in the extracts enhance the plant’s capacity to combat oxidative damage, potentially benefiting liver health and overall immune function.
6. Alkaloids: Various alkaloids beyond febrifugine offer antimicrobial properties, supporting infection control, but they are not considered nutritional in a dietary sense due to potential toxicity.
7. Coumarins: Trace coumarins contribute to anticoagulant and anti-inflammatory effects, which may indirectly support vascular health in traditional preparations.
8. Polysaccharides: Found in the roots, these complex carbohydrates may act as prebiotics, promoting gut health and enhancing the absorption of other bioactive compounds.
9. Tannins: These polyphenolic compounds provide astringent properties, aiding in wound healing and reducing inflammation, with minor antioxidant benefits.
10. Glycosides: Including hydrangenoside C, glycosides support anti-inflammatory activities and may contribute to the plant’s overall pharmacological profile for fever reduction.
Dichroa febrifuga is primarily a medicinal herb rather than a nutritional food source, valued for its bioactive compounds like alkaloids and flavonoids that offer antioxidant and anti-inflammatory benefits. Due to its toxicity, particularly from febrifugine, it should not be consumed directly and is best used in controlled extracts under professional guidance.
Scientific Evidence and Case Studies on Dichroa (Dichroa febrifuga)
