Nutritional Profile

Du Zhong (Eucommia ulmoides) bark is not consumed as a macronutrient source but contains a rich array of bioactive compounds. Key bioactive constituents include: Lignans - pinoresinol diglucoside (approximately 0.3-1.2% dry weight), the primary active lignan responsible for many therapeutic effects; Iridoids - aucubin and geniposidic acid (0.5-2.0% dry weight), contributing to anti-inflammatory and hepatoprotective actions; Chlorogenic acid (0.1-0.5% dry weight), a phenolic antioxidant with cardiovascular benefits; Du Zhong rubber/gutta-percha (up to 6-10% in bark), trans-polyisoprene polymer unique to this plant; Flavonoids including quercetin and kaempferol derivatives (0.05-0.2% dry weight); Polysaccharides (approximately 3-8% dry weight) with immunomodulatory properties; Ulmoprenol and other triterpenoids (trace amounts, ~0.01-0.05%); Micronutrients: potassium (~400-600 mg/100g dry bark), calcium (~200-350 mg/100g), magnesium (~80-120 mg/100g), zinc (~2-4 mg/100g), manganese (~1-3 mg/100g); Protein content is minimal (~2-4% dry weight, primarily structural proteins); Fiber content approximately 15-25% dry weight (largely insoluble). Bioavailability notes: Pinoresinol diglucoside undergoes gut microbiome conversion to bioavailable aglycone forms; chlorogenic acid bioavailability is estimated at 15-30%; water extraction (decoction) yields higher iridoid and polysaccharide content, while ethanol extraction favors lignans and flavonoids; standardized extracts are typically normalized to 10-15% total iridoids or 0.1% pinoresinol diglucoside.

Reported Mechanism (Provisional)

Mechanism of Action

Du Zhong's primary bioactive compounds include chlorogenic acids, geniposidic acid, and lignans like pinoresinol diglucoside. These compounds inhibit osteoclast activity while stimulating osteoblast differentiation through Wnt/β-catenin signaling pathway activation. The herb also modulates the NF-κB inflammatory pathway and enhances nitric oxide production for cardiovascular benefits.

Clinical Narrative (Provisional)

Clinical studies on Du Zhong are limited but promising. A 12-week trial with 80 postmenopausal women showed 15% improvement in bone mineral density markers compared to placebo. Animal studies demonstrate significant anti-inflammatory effects and 25-30% reduction in arthritis-related joint damage. Human cardiovascular studies are preliminary, with one small trial showing modest blood pressure reductions in 40 participants over 8 weeks.
