Valerian Root Extract (derived from Valeriana officinalis) has emerged as one of the most in-demand botanical raw materials worldwide. Driven by a global shift toward clean-label, plant-based alternatives for mental wellness, stress relief, and natural sleep support, the industrial application of this ancient botanical has scaled dramatically.
Global market reports indicate that the segment for sleep-support ingredients is expanding at a compound annual growth rate (CAGR) of over 6.8%. Phytomedicines and dietary supplements containing standardized Valerian Extract are dominating retail shelves in North America, Western Europe, and Asia-Pacific. As modern consumers turn away from synthetic sedatives due to concerns over dependency and morning grogginess, standardized Valerenic Acid has become a staple active ingredient in high-performance natural blends.
For B2B buyers—ranging from contract manufacturers to formula developers—securing a stable, certified, and scientifically validated source of Valerian Extract is critical to navigating strict regulatory environments and ensuring batch-to-batch consistency.
Delivering high efficacy requires a deep understanding of Valerian's active chemical matrix and precise quantification methods.
Valerenic acids (including valerenic, acetoxyvalerenic, and hydroxyvalerenic acid) are the primary active sesquiterpenoids responsible for modulating GABA-A receptors. We standardize our extract up to 0.8% HPLC to guarantee pharmacological efficacy.
Valerian's distinctive aroma comes from its volatile oils (chiefly bornyl acetate and caryophyllene). Our low-temperature vacuum extraction preservation technology ensures that volatile components remain balanced without degradation.
While valepotriates contribute to therapeutic properties, they are highly unstable and can degrade during storage. Our stabilization process carefully monitors and limits these degradation pathways to prolong shelf life.

Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) is a leading technology-based manufacturer of standardized botanical extracts.
For more than 20 years, TRB has operated at the intersection of agronomic tradition and advanced extraction science. As a specialized manufacturer and exporter, we integrate scientific research and development, modern production lines, and international sales pipelines to supply premium raw materials to over 60 countries.
Our capabilities extend beyond standard extraction. Our active portfolios feature Herbal Extracts, Natural Sweeteners, Nootropics, Vegetable & Fruit Juice Powders, Essential Oils, and Bee Products.
TRB's commitment to industrial reliability, safety compliance, and supply chain transparency has been widely recognized. We are proud recipients of the 2026 Global Biotechnology and Life Sciences Award — "Best Global Herbal Extract Provider 2026".
How our modern factories preserve delicate phytoconstituents while eliminating residual impurities.
Valerian root's therapeutic profile is highly susceptible to heat degradation. TRB's manufacturing plants employ state-of-the-art closed-loop hydro-alcoholic extraction lines operating under low-temperature vacuum conditions. This methodology ensures that the volatile terpenoids and unstable valepotriates remain structurally intact, preserving the extract's synergistic biochemical fingerprint.
To support global supply chains, we maintain three highly specialized factories: one for herbal extracts, one for bee products, and another dedicated to animal extract lines. Across these facilities, quality control is governed by comprehensive international certifications, including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER.
Our extraction technology yields active substances free from harsh organic solvents, ensuring that your finished products conform to USDA Organic, EU Organic, and Prop 65 safety regulations.
Tailored product profiles designed for diverse consumer product formats.
Our dry powders (standardized up to 0.8% Valerenic acid) feature optimized particle sizes, making them ideal for hard-shell encapsulation, double-compressed tablets, and premium softgel formulas. Excellent flowability prevents manufacturing downtime.
For night-time teas, RTD (Ready-To-Drink) wellness waters, and powdered drink mixes, we provide highly water-soluble Valerian Extract. This specialized grade dissolves completely without precipitation, sediment, or excessive cloudiness, and features an optimized taste profile.
With the pet wellness industry surging, manufacturers formulate botanical calming chews and liquids for dogs and cats. We offer pet-safe grades compliant with strict heavy-metal and pesticide thresholds, suitable for functional extrusion processes.
