A comprehensive overview of global demand, biochemical metrics, and standardizations in natural seed extraction.
Amygdalin, a naturally occurring cyanogenic glycoside found abundantly in the seeds of Prunus armeniaca (bitter almonds), has gained prominent status across pharmaceutical, dietary supplement, and biotechnology sectors. Often referred to under various industrial nomenclatures including Vitamin B17, it serves as a critical component in research frameworks focusing on enzyme-activated prodrug systems, traditional therapeutics, and cellular health formulations.
As the international community moves toward botanical standardization, global sourcing demands have evolved beyond simple volume parameters. Today's procurement directors require strict validation protocols, including high-performance liquid chromatography (HPLC) finger-printing, residual solvent monitoring, and advanced heavy metal profiling. TRB meets these demanding criteria by providing high-purity natural Amygdalin ranging from 98% to 99% assay standards.
A leading force in global botanical extraction and pharmaceutical-grade manufacturing for over two decades.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has been the leading manufacturer and exporter of premium herbal extracts and biological derivatives in China for more than 20 years.

Addressing supply chain risks, quality parameters, and macro industry challenges in Vitamin B17 sourcing.
Because Amygdalin is a cyanogenic compound, maintaining tight control over enzymatic breakdown during raw material processing is paramount. TRB utilizes advanced thermal denaturation parameters to deactivate endogenous beta-glucosidase enzymes immediately upon seed crushing, ensuring chemical stability and a low free-HCN profile in the final extract powder.
Different product formats demand precise physical attributes. Dietary supplements in capsule format require optimized powder flowability, while liquid formulations demand high dissolution speeds. TRB offers custom milling and micronization from 80 mesh up to super-fine 200 mesh grades to fit your production infrastructure.
Global logistics bottlenecks make predictable supply agreements essential. TRB's production factories operate continuously with stable access to agricultural heartlands in Northern China (where the highest quality bitter almonds are grown). This guarantees reliable year-round raw materials, isolated from seasonal price fluctuations.
At TRB, the manufacturing process of Amygdalin is a science-driven enterprise. Apricot kernels undergo careful sorting, defatting, and low-temperature ethanol extraction. By avoiding high-toxicity solvent systems, we maintain a green chemistry approach, ensuring zero toxic residues (such as benzene or chlorinated solvents) in the final product.
TRB currently operates three dedicated factories: one herbal extract factory, one bee product factory, and one specialized animal extract facility. These plants are certified with internationally recognized standards, including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER Certificates. These certifications guarantee that each batch meets international import specifications without delay.
In recent years, TRB has made substantial investments in the R&D of brain health, longevity, and anti-aging compounds. We are focused on studying synergetic relationships between plant-based molecules (like Amygdalin) and modern longevity catalysts.
Our focus areas include:
These specialized research pathways have earned high praise and excellent product feedback from leading supplement and pharmaceutical brands in Europe, North America, and Japan.
Providing ironclad certification pathways for global customs clearances and premium quality standards.
Exporting ingredients to strict regulatory markets (such as the EU, North America, and East Asia) demands comprehensive documentation. TRB provides a full regulatory dossier for every single consignment, including detailed Certificate of Analysis (COA) sheets, allergen reports, BSE/TSE-free statements, and non-GMO affirmations.
Whether you require USDA Organic certification for clean-label products, Kosher/Halal for multi-cultural markets, or GMP-conforming documentation for pharmaceutical formulations, TRB handles the administrative workload to ensure seamless custom clearances.
Exploring biotechnology and green extraction innovations designed for next-generation formulations.
By integrating machine learning algorithms with automated solid-liquid extraction loops, TRB is optimizing solvent utilization rates and energy inputs. This lowers extraction costs, passing on valuable economies of scale to our bulk-buy procurement partners.
We are piloting supercritical CO2 extraction methods for purifying Amygdalin. This process operates without organic solvents, resulting in ultra-clean extracts designed to meet the strict demands of eco-conscious global consumers.
TRB products are exported to more than 60 countries and regions. By partnering with leading logistics hubs in Shanghai and Shenzhen, we offer multiple shipping options (CIF, FOB, DDP, DAP) via air, sea, or express courier, maintaining cargo integrity from our warehouse to yours.
Answering key compliance, purity, stability, and logistic queries for industrial buyers.
