ODM Gynostemma Pentaphyllum Extract Manufacturers & Factory

UV spectrophotometry employs a colorimetric reaction (commonly vanillin-perchloric acid or sulfuric acid) that reacts with any dammarane or triterpene backbone, including non-gypenoside sterols and organic impurities. This often produces false-positive over-quantification. HPLC-ELSD (High-Performance Liquid Chromatography coupled with Evaporative Light Scattering Detection) physically separates each saponin molecule across a C18 reverse-phase column and detects them mass-dependently without relying on chromophores. For international compliance and tier-1 product safety, we provide HPLC-ELSD quantification for individual reference peaks such as Gypenoside XLIX and Gypenoside A.

Functionally and biochemically, Gynostemma shares identical active saponins (e.g., Ginsenosides Rb1, Rb3, and Rd) with Panax ginseng and Panax quinquefolius, conferring equivalent adaptogenic, mitochondrial, and metabolic benefits. However, from a regulatory standpoint (such as FDA 21 CFR or EU food supplement listings), it must be clearly labeled by its approved botanical binomial—Gynostemma pentaphyllum—and cannot be misrepresented on finished packaging as Panax species. Formulators frequently market it under the recognized identity of "Jiaogulan" or "Southern Ginseng Extract".

Cucurbitaceae vines naturally accumulate trace minerals from their terroir. To guarantee total heavy metal concentrations well below strict US and European limits (Pb < 1.0 ppm, As < 1.0 ppm, Cd < 0.5 ppm, Hg < 0.1 ppm), we implement a three-tiered control strategy: (1) Soil baseline mineral testing at contracted GAP farming zones in Shaanxi; (2) In-line chelation resin adsorption during the liquid purification cycle; (3) Final batch verification via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) documented on the COA.

Native, unrefined Gynostemma extracts often contain hydrophobic waxes and bitter sapogenins that can form haze or sediment in cold liquids. To solve this for beverage manufacturers, we offer our specialized De-Bittered Instant Grade (20%–30% Gypenosides). This grade undergoes enzymatic de-lipidation and membrane clarification, resulting in 100% optical clarity in cold aqueous solutions (pH 3.2–6.5) with neutral organoleptic characteristics and zero precipitation over a 24-month stability window.

Our standard commercial packaging is 25 kg fiber drums lined with double pharmaceutical-grade polyethylene bags and heat-sealed desiccants to safeguard hygroscopic powders from ambient humidity. For pilot production or custom R&D batches, our minimum order quantity starts at 1 kg for premium high-assay grades (80%–98% HPLC) and 25 kg for standard industrial commercial grades. We routinely dispatch pre-shipment qualification samples (50–100g) alongside analytical chromatograms.

When maintained in the original unopened drums in a dry, ventilated, temperature-regulated warehouse (<25°C, relative humidity <60%), our standardized powder extracts have a validated shelf-life of 24 to 36 months from the date of manufacture. Real-time and accelerated stability studies demonstrate a saponin loss of less than 1.8% per year under recommended storage parameters.

Yes. Beyond supplying raw botanical powders, our cGMP production suites deliver comprehensive contract dosage forms. We handle excipient optimization (e.g., microcrystalline cellulose, silica), clean-label flow agents, vegetable HPMC or pullulan capsule filling, primary HDPE bottle packaging with child-resistant caps, carton box printing, and third-party laboratory verification—enabling your team to launch fully qualified finished SKUs efficiently.
