Bulk Trilobatin Sweet Tea Extract Supplier — Natural Dihydrochalcone Sweetener from Lithocarpus polystachyus

Written by Jonathan, Valeherb · Reviewed by Dr. Xiaoyan Qiu · Updated April 2026

If you are sourcing a natural high-intensity sweetener for clean-label food, beverage, or supplement formulation, trilobatin delivers a profile that stevia and monk fruit cannot replicate: sugar-like sweetness at approximately 300× the intensity of sucrose, no bitter or licorice aftertaste, full heat and pH stability across manufacturing conditions, and bioactive properties studied in published research — all from a single botanical source. Valeherb is a dedicated trilobatin sweet tea extract bulk supplier in Huaihua, China, offering standardized extracts from 30% to 98% trilobatin purity for B2B procurement.


What Is Trilobatin? Compound Identity and Botanical Source

Trilobatin (CAS: 4192-90-9) is a naturally occurring dihydrochalcone — a class of polyphenolic glycosides structurally related to phloretin. Its botanical source is Lithocarpus polystachyus (Chinese sweet tea, 多穗石柯; also known as Lithocarpus litseifolius), a broadleaf evergreen native to the mountainous regions of Hunan, Guangdong, and Guangxi provinces in southern China, where its leaves have been consumed as a traditional sweet herbal tea for centuries.

WHY VALEHERB
Trilobatin is not yet a commodity ingredient — the supply chain is concentrated, and most bulk material originates from a small number of cultivation regions in southern China. At Valeherb, our R&D team, led by Dr. Xiaoyan Qiu, has conducted direct research on Lithocarpus polystachyus (Yao tea) as part of her work on medicinal plant resources at Huaihua University — the same region where the highest-quality cultivation occurs. This gives us first-hand knowledge of harvest timing, seasonal compound variability, and the extraction protocols required to preserve trilobatin’s compositional profile at commercial scale.

Trilobatin vs. Stevia vs. Monk Fruit: The Formulator’s Comparison

Compound Research: Beyond Sweetness

Alongside its sweetness profile, trilobatin is a polyphenolic dihydrochalcone that has been the subject of published bioactivity research. The summaries below describe findings reported in peer-reviewed literature for informational purposes only. They are not claims for any Valeherb product, and trilobatin is supplied as a flavour and food ingredient — not for any therapeutic use.

1. Alpha-Glucosidase Inhibition Research

In published enzyme-kinetics research, trilobatin has been studied as an alpha-glucosidase inhibitor. He et al. (2022) reported that trilobatin reversibly inhibits α-glucosidase in a noncompetitive manner, with a reported IC50 of 0.24 ± 0.02 mM in an in vitro assay combined with molecular docking analysis.[3] These are in vitro findings reported in peer-reviewed literature and are described here for informational purposes.

2. Hepatic Lipid Research (Animal Model)

In an animal-model study, Zhang et al. (2022) examined trilobatin’s effects on hepatic lipid accumulation and NLRP3 inflammasome activity.[4] These are preclinical animal-study findings reported in peer-reviewed literature; they are described here for informational purposes and are not claims for any product.

3. Antioxidant and Inflammatory-Pathway Research

As a polyphenolic dihydrochalcone, trilobatin demonstrates free radical scavenging activity in published research. In published studies it has also been observed to modulate pro-inflammatory cytokine markers (TNF-α, IL-1β, IL-6) and NF-κB pathway activity.[5] These findings are reported in peer-reviewed literature and are described here for informational purposes.


Sourcing and Purity: Why Production Quality Determines Formulation Performance

Trilobatin and phlorizin are structurally related dihydrochalcones that co-occur in Lithocarpus polystachyus leaf material. Separating them requires precise chromatographic processing — suppliers without dedicated separation infrastructure deliver mixed dihydrochalcone extracts with inconsistent sweetness profiles and unpredictable active-compound content.

PRODUCTION NOTE
Harvest timing directly determines raw material quality. April collections from Lithocarpus polystachyus leaves consistently yield peak trilobatin concentrations before seasonal phenolic degradation occurs. At Valeherb, we source exclusively from documented April harvest batches and apply temperature-controlled extraction protocols to preserve the dihydrochalcone structure post-processing. Every production lot is tested for trilobatin vs. phlorizin ratio by HPLC — because a “sweet tea extract” COA that does not separately quantify trilobatin content tells you nothing about sweetness performance or trilobatin content in your finished product.

Available Specifications and Formulation Guidance

Purity Grade Trilobatin Content Recommended Application Typical Use Level
Standard Extract 30% trilobatin by HPLC Functional food fortification, herbal tea blends, traditional wellness products 0.02–0.05% in beverage
High-Purity Extract 40–60% trilobatin by HPLC Functional beverages, nutraceutical capsules, clean-label sweetener applications 0.005–0.02% in beverage
Premium Grade 92–98% trilobatin by HPLC Precision functional food formulations, supplement applications, research applications 0.001–0.005% in beverage
  • Beverage formulation: Trilobatin performs cleanly at 0.005–0.02% in water-based systems. Synergistic blending with erythritol (50–70% of sweetness base) improves mouthfeel and reduces overall sweetener cost while maintaining clean flavor profile
  • Supplement capsules/tablets: High-purity grades (40%+) for supplement applications. Typical extract loading: 50–200 mg per serving depending on purity grade and formulation
  • Baked goods and high-temperature processing: Standard and high-purity grades are both stable above 120°C — confirmed through Valeherb internal stability testing. No sweetness degradation observed in retort or autoclave processing conditions
  • Synergistic blending: Pairs effectively with monk fruit and erythritol. Trilobatin’s clean sweetness profile masks monk fruit’s mild aftertaste at low inclusion rates, enabling cost-optimized clean-label sweetener systems

FAQ

A1:Trilobatin is a naturally occurring dihydrochalcone — a polyphenolic glycoside extracted from the leaves of Lithocarpus polystachyus (Chinese sweet tea), a broadleaf evergreen tree native to southern China. It delivers approximately 300 times the sweetness intensity of sucrose with a clean, sugar-like taste profile and minimal aftertaste — distinguishing it from stevia, which carries bitter or licorice-like notes at higher concentrations.
A2:Trilobatin holds FEMA GRAS status (Flavor and Extract Manufacturers Association) and has been evaluated by JECFA (Joint FAO/WHO Expert Committee on Food Additives), providing the primary US and international regulatory coverage required for food and beverage ingredient use. In China, Lithocarpus polystachyus leaf extract is approved under GB food standards. In the EU and Canada, trilobatin is not currently listed as an authorized sweetener — novel food or flavor ingredient regulatory pathways apply in these markets. Given the evolving regulatory landscape for this ingredient, consulting a qualified regulatory specialist before finalizing product claims and market entry strategy is recommended.
A3:Trilobatin offers three formulation advantages over stevia and monk fruit: cleaner taste profile (no bitter or licorice aftertaste at typical use levels), superior heat and pH stability (stable above 120°C and across pH 3–8, covering retort, autoclave, and carbonated beverage conditions), and documented bioactive function at ingredient use levels that neither stevia nor monk fruit can match. For cost optimization, trilobatin pairs synergistically with erythritol and monk fruit — trilobatin’s clean sweetness masks monk fruit’s mild aftertaste, enabling lower-cost blended sweetener systems while maintaining clean-label positioning.
A4:The correct purity grade depends on your application. For functional beverages and RTD products, 40–60% trilobatin by HPLC is the standard specification — effective at 0.005–0.02% use level with reliable sweetness consistency. For high-precision nutraceutical capsules or precision functional food applications where trilobatin content needs to be declared on label, 92–98% purity provides the concentration accuracy required. Standard 30% extract is appropriate for herbal tea blends and traditional wellness products where exact trilobatin dosing is less critical. Always require individual HPLC quantification of trilobatin versus phlorizin on the COA — a ‘sweet tea extract’ specification without this breakdown does not confirm sweetness performance.
