Overview
Eucommia Leaf Raw Powder is obtained from the dried leaves of Eucommia ulmoides, a tree native to China and traditionally used in herbal medicine. The powder retains the plant's bioactive constituents, including chlorogenic acid, aucubin, and lignans, which contribute to its therapeutic properties. Modern processing techniques, such as low-temperature drying and fine milling, ensure the preservation of these compounds. The powder is increasingly sought after in global markets for its applications in health supplements and functional foods, aligning with the growing demand for plant-based wellness products.
Physical and Chemical Properties
The powder exhibits a characteristic greenish-brown hue and a slightly bitter taste, indicative of its high polyphenol content. Its partial solubility in water allows for versatile formulation in beverages, while ethanol solubility is leveraged for tinctures and extracts. Key active components like chlorogenic acid (typically 3–5% by weight) and aucubin (1–3%) are standardized in commercial grades. The powder's hygroscopic nature necessitates careful storage to prevent clumping or degradation. Analytical methods such as HPLC are used to quantify potency and ensure batch consistency.
Main Applications
In nutraceuticals, the powder is encapsulated or tableted for cardiovascular and joint health supplements. Its anti-inflammatory properties make it a candidate for sports nutrition products targeting recovery. The food industry incorporates it into health drinks, energy bars, and teas. Traditional Chinese Medicine (TCM) formulations use it synergistically with other herbs to enhance kidney and liver function. Emerging research explores its potential in cosmetic formulations for antioxidant benefits.
Safety and Storage
While classified as GRAS, recommended daily intake should not exceed 3–5 grams without medical supervision. Rare cases of mild gastrointestinal discomfort have been reported. Storage requires protection from humidity and UV exposure to prevent oxidation of active compounds. Vacuum-sealed bags with desiccants are ideal for bulk packaging. Shelf life is 24 months when stored below 25°C with <60% relative humidity.
B2B Procurement Guide
Buyers should prioritize suppliers providing Certificate of Analysis (CoA) with HPLC profiles for chlorogenic acid and aucubin. Organic certification (e.g., USDA, EU) is critical for markets with strict regulatory standards. Minimum Order Quantities (MOQs) typically start at 25 kg, with price breaks at 100+ kg. Sample testing for heavy metals (lead, arsenic) and microbial contamination (total plate count, yeast/mold) is advised. Logistics planning should account for the powder's sensitivity to temperature fluctuations during transit.
