Notoginseng Extract
Notoginseng (Panax notoginseng) Extract: Production, Appearance, and Benefits
Notoginseng extract is derived from the roots of Panax notoginseng, a prized medicinal plant in traditional Chinese medicine. The production involves:
Cultivation & Harvesting:
Grown for 3–7 years in Yunnan, China, at high altitudes (1,200–1,800m) for optimal saponin content.
Roots are hand-harvested in autumn, graded by size and quality.
Processing:
Cleaning & Slicing: Roots are washed, sun-dried, and cut into thin slices or powder.
Extraction:
Water Extraction: For polysaccharides and amino acids.
Ethanol Extraction: Concentrates ginsenosides (Rb1, Rg1, Rd).
Purification: Macroporous resin chromatography isolates target compounds (e.g., notoginsenoside R1).
Standardization: Adjusted to 5–10% total saponins for potency.
Forms:
Brownish-red powder (spray-dried).
Liquid extract (dark amber).
Capsules/tablets.
Color:
Powder: Light brown to reddish-tan.
Liquid: Deep amber with reddish tint.
Taste: Bitter initially, with a lingering sweet aftertaste.
Solubility: Water-soluble (powder); alcohol-soluble (liquid).
Renowned as "the king of hemostatics" in TCM, its bioactive compounds (ginsenosides, notoginsenosides) offer:
Circulatory Health:
Stops bleeding and promotes wound healing (used post-surgery in China).
Reduces blood viscosity, improving microcirculation.
Cardiovascular Protection:
Lowers LDL cholesterol by 20–25% (Journal of Functional Foods).
Inhibits platelet aggregation, reducing thrombosis risk.
Anti-Inflammatory & Pain Relief:
Effective for traumatic swelling and arthritis pain.
Neuroprotection:
Ginsenoside Rb1 enhances memory and protects against Alzheimer’s.
Metabolic Support:
Regulates blood sugar and reduces insulin resistance.
Applications:
Hemostatic agents: In trauma medicine.
Supplements: 100–500 mg/day for circulation.
Cosmeceuticals: Wound-healing creams.
Note: Often combined with Salvia miltiorrhiza (Danshen) for synergistic cardiovascular effects.
