Product Description

Gastrodia Extract is derived from the precious traditional Chinese herb Gastrodia elata, with over 2000 years of documented medicinal use dating back to "Shennong's Classic of Materia Medica." Modern research confirms its multiple pharmacological effects including sedative-hypnotic, anticonvulsant, anti-vertigo, cerebral circulation improvement, and memory enhancement properties.

Our extract utilizes supercritical CO₂ extraction or water-alcohol precipitation to ensure high purity and bioactivity. Rigorously tested by HPLC and UV methods, it meets international standards for pharmaceutical, nutraceutical, functional food, and cosmetic applications.

The key advantage lies in its multi-target neuromodulatory capacity - simultaneously improving cerebral blood flow while protecting neurons, combined with antioxidant and anti-inflammatory effects.

Active Components:

Gastrodin (≥5%-98%)

Gastrodigenin

Gastrodia Polysaccharides

Vanillyl Alcohol, Vanillin

Vitamin A compounds, β-sitosterol, trace elements (chromium, manganese, iron, etc.)

Technical Analysis

Extraction Methods

Water extraction-alcohol precipitation: Optimal for polysaccharides and flavonoids

Supercritical CO₂ extraction: Produces high-purity gastrodin without solvent residues

Enzymatic-assisted extraction: Enhances gastrodin glycoside yield

Quality Control

Content analysis: HPLC quantification of gastrodin (≥98%)

Heavy metal limits: Lead ≤2ppm, Arsenic ≤2ppm, Mercury ≤2ppm, Cadmium ≤2ppm

Microbial limits: Total bacterial count ≤1000CFU/g, Mold ≤100CFU/g

Clinical Evidence

Cerebrovascular improvement: Gastrodin dilates cerebral vessels, increasing blood flow for vertebrobasilar insufficiency

Sedative effects: Prolongs slow-wave sleep duration for insomnia and neurasthenia

Anticonvulsant: Gastrodigenin reduces epileptic seizures and neuronal damage

Memory enhancement: Polysaccharides promote hippocampal neuron growth and learning capacity
