Product Introduction

Gypenosides powder is a high-quality botanical extract of stems and leaves of Jiaogulan, a famous adaptogenic plant of the Cucurbitaceae family. This powder contains over 80 unique saponins called Gypenosides. They are structurally similar to the ginsenosides found in Panax Ginseng but without any stimulating side effects. We employ innovative spray-drying and freeze-drying methods to isolate and improve water solubility and bioavailability, thereby broadening the potential applications of our product to a wide range of uses, including nutritional supplements, functional beverages, and cosmetic formulations. Fine power , 80-100 mesh , standard Gypenosides by HPLC 10%~98%. Good stability on heat processing and compression.

Gynostemma Pentaphyllum Powder Advantages

Standardised Potency Guarantee: Our HPLC-tested powder ensures that each production lot has the same Gypenoside profile. No formulation variability to jeopardise end product efficacy and customer satisfaction.

Superior Bioavailability: Fine particle size is obtained by advanced extraction methodology with optimised water solubility resulting in quick dissolving in beverage systems and better absorption when encapsulated in dietary supplements.

Thermal Processing Stability: The powder is stable at pasteurisation temperatures up to 85°C with no degradation of active compounds, ideal for hot-fill beverage processes without loss of potency.

Low Bitterness Profile: Our unique extraction technology minimises strong saponin bitterness while preserving active content, minimising the need for flavour masking and lowering formulation expenses for your R&D team.

good Compressibility: The powder has good tableting properties with conventional excipients such as microcrystalline cellulose. Controlled bulk density of 0.45-0.65g/ml and excellent flowability.

Gynostemma Pentaphyllum Powder Application

Metabolic Health Supplements: This powder is used by formulators in weight management products for its AMPK activation capabilities that support healthy glucose metabolism and lipid profiles when paired with complementing substances like Berberine.

Adaptogenic Beverage Systems: Ready-to-drink tea makers are applying it in stress relief and energy drinks, taking advantage of its cold-water solubility and pH stability (3.0-4.0) for clear, sediment-free functional beverages without using synthetic stimulants.

Cardiovascular Support Formulas: Nutraceutical products that promote heart health use the powder for its proven benefits on healthy cholesterol levels and antioxidant activity. It is typically combined with Coenzyme Q10 or Omega-3s.

Anti-Aging Cosmetic Lines: Used by personal care producers in serums and creams for its antioxidant and anti-inflammatory qualities. Compatible with non-ionic emulsion systems, it helps to strengthen skin barrier function.

Production Process

Step 1 - Raw Material Selection: We obtain high-grade Gynostemma leaves from our GAP-certified planting bases in the best maturity periods. Only leaves with confirmed botanical identity and a minimum of 8% natural Gypenoside content are allowed in manufacture.

Step 2 - Cleaning and Preparation: Fresh materials are washed multiple times with filtered water and mechanically sorted to remove stems and contaminants. Result: Clean and homogenous plant material for efficient extraction.

Step 3 - Aqueous-Ethanol Extraction: We treat our materials in temperature-controlled extraction tanks utilising optimised ratios of water to ethanol to maximise the production of Gypenosides. Result: Concentrated liquid extract containing saponin target chemicals.

Step 4 - Filtration and Concentration: The extract is passed through precision filtration systems and then vacuum concentration at controlled temperatures below 60 degrees Celsius. Purified concentrated solution. Minimal thermal degradation.

Step 5 - Spray Drying: The concentrated extract is spray dried in our GMP workshop at an intake temperature of 180-200°C and an exit temperature of 80-90°C. Result: Fine free flowing Gynostemma Pentaphyllum Powder with specified requirements.

Step 6 - Quality Testing: Every batch receives comprehensive testing including HPLC assay, microbial analysis, heavy metals, and pesticide residue screening. Result: COA certified powder, international standard quality.

Step 7 - Packaging and Storage: The qualified powder is packed in double layer PE bags in fibre drums and stored in climate controlled warehouses. Result: Protected product with a 24 month shelf life when properly stored.

Third-Party Test Report
