In the world of traditional Chinese medicine, Panax notoginseng is known as "the irreplaceable gold," and its extracted total saponins are called "plant gold," playing a vital role in cardiovascular health and other areas.
The creation of this precious extract relies on strict quality control at every step. Today, let's explore the production process of Panax notoginseng total saponins.
High-Quality Raw Materials, the Foundation of Quality
It all starts with high-quality Panax notoginseng raw materials. Ours comes from Wenshan, Yunnan—globally recognized as the "home of Panax notoginseng."
The unique red soil, abundant sunlight, and suitable humidity of this region nurture Panax notoginseng with significantly higher effective ingredient content than other regions.
Every batch of incoming Panax notoginseng raw materials undergoes rigorous quality testing. Only those with full size, no mildew, and sufficient effective ingredient content are allowed into the production line, ensuring quality from the source.
Washing and Preprocessing: Meticulous Attention to Detail
After raw material qualification, the washing and preprocessing steps are crucial.
As per pharmacopoeia requirements, Panax notoginseng must be repeatedly washed with purified water to remove mud, sand, pesticide residues, and other impurities to avoid contamination of effective ingredients.
The washed Panax notoginseng is pulverized into fine powder of a suitable particle size. This process is also strictly controlled to ensure uniform particle size, laying the foundation for subsequent extraction efficiency and quality.
Core Extraction: Scientific and Rigorous
The extraction process is the core of production and must strictly follow the scientific methods recommended in the pharmacopoeia.
We use the pharmacopoeia-approved alcohol extraction method, using edible ethanol as the solvent. Under specified temperature, time, and material-liquid ratio conditions, the Panax notoginseng powder and solvent are allowed to fully contact, maximizing the dissolution of Panax notoginseng total saponins.
This process requires real-time monitoring of parameters such as temperature and pressure to ensure stable extraction conditions for each batch and consistent product quality.
Separation and Purification: Striving for Excellence
The extracted mixed solution needs to undergo separation and purification.
First, insoluble substances are removed through precise filtration, and then pharmacopoeia-recommended separation techniques such as macroporous adsorption resin are used to further purify the Panax notoginseng total saponins.
Each separation operation strictly adjusts parameters according to pharmacopoeia standards, removing impurities and concentrating effective ingredients to gradually improve the purity of the extract.
Strict Quality Inspection: The Final Checkpoint
Near the end of production, quality testing becomes a critical checkpoint.
We conduct a comprehensive "physical examination" of the product based on the testing standards for Panax notoginseng total saponins in the Chinese Pharmacopoeia:
High-performance liquid chromatography is used to determine the content of Panax notoginseng total saponins, ensuring it meets the specified standards;
Heavy metal and pesticide residue testing ensures product safety and harmlessness;
Microbial limit testing eliminates contamination by bacteria and fungi.
Only when every test result meets the pharmacopoeia requirements can the product be successfully shipped.
With the pharmacopoeia as our standard and craftsmanship as our guide, we ensure that every step in the production of Panax notoginseng total saponins is standardized and rigorous. This adherence to standards is not only a continuation of the tradition of traditional Chinese medicine but also a solemn commitment to consumer health.
