Gynostemma Extract Powder 98% Saponins

Gynostemma pentaphyllum (Thunb.) Makino; Total saponins (gypenosides) 98.0% by UV.

Description

STANDARDISED BOTANICAL ACTIVE

Gynostemma pentaphyllum Whole Herb — 98% Saponins

Gynostemma saponins are sold as a group rather than as a single molecule, so the 98% figure describes total gypenoside content. Buyers comparing two 98% offers should ask for the saponin profile, because the individual gypenoside distribution drives both taste and price.

Buyer Decision Guide

Ask whether the assay is on total saponins or on a named gypenoside, and which method was used. UV and HPLC figures for the same lot are not directly interchangeable.

  • Assay: total saponins 98.0% by UV, with the calculation basis stated on the COA.
  • Method note: UV measures total saponins; if your specification is HPLC-based, say so before ordering.
  • Marker: gypenosides as a group. No single gypenoside is specified at this grade.
  • Appearance: light yellow to brownish-yellow powder. Strong brown tones point to over-heating during drying.
  • Solubility: water-soluble, with a pronounced bitterness that carries into the finished product.
  • Documentation: COA, specification sheet and SDS issued with each batch.

How This Grade Differs

No gynostemma grade was listed on the site before this page, so this introduces the product directly at 98%. The 4:1 and 10:1 ratio grades common in the market are a different purchase with a different price basis.

Quality and Documentation

Released on a batch certificate covering total saponins, method, moisture, heavy metals and microbiology.
