Phytochemical Analysis and Pharmacological Applications of Eucommia Ulmoides

Eucommia ulmoides Oliv., commonly known as Du Zhong, has long featured in traditional Chinese medicine and is increasingly the focus of modern phytochemical and pharmacological research. Phytochemical analyses have revealed a rich array of iridoids (notably aucubin and geniposidic acid), lignans (such as pinoresinol diglucoside), flavonoids (including rutin and quercetin) and phenolic acids (for example chlorogenic acid). Advances in chromatographic and mass-spectrometric techniques have enabled quantitative profiling of these constituents in bark, leaf and flower, illuminating their seasonal and organ-specific variation. Pharmacological studies in vitro and in vivo indicate that E. ulmoides extracts and purified constituents exert antioxidant, anti-inflammatory, cardioprotective, neuroprotective, antihypertensive, antidiabetic and osteoprotective effects. Mechanistic investigations point to modulation of nitric oxide bioavailability, inhibition of pro-inflammatory enzymes, regulation of endoplasmic reticulum stress and enhancement of lysosomal activity. Translation of these findings into functional foods, nutraceuticals and standardised herbal preparations underscores the global potential of E. ulmoides for metabolic, cardiovascular and neurological health.
