Jujube seed extract 2% jujuboside for calming supplements
product description
Standardized jujube seed extract powder derived from the dried mature seeds of Ziziphus jujuba var. spinosa — the traditional Chinese botanical Suan Zao Ren used for calming support for over two thousand years. Each batch is standardized by HPLC to a minimum of 2% jujubosides A & B, the industry reference specification for calming and sleep-support supplement concepts. Our ethanol-water extraction, macroporous resin purification and spray-drying process preserves the full saponin and flavonoid profile in a consistent, free-flowing, water-dispersible powder for dietary supplement, functional food, personal care and pet calming formulations.
Extraction & Standardization
Why 2% Jujuboside Is the Market Reference Specification
A "standardized" botanical extract guarantees a minimum content of a measurable marker in every batch. For jujube seed extract, 2% total jujubosides (A+B, quantified by HPLC against reference standards) has become the de facto industry specification—the grade most widely quoted by formulators, listed in supplier catalogs, and used in finished sleep-support SKUs. It represents a sensible balance between pharmacological relevance, extract yield, and cost. A 10:1 ratio extract preserves the whole-spectrum profile of the traditional decoction without a marker guarantee. If you are unsure which grade fits your product, our technical team can review your target serving size and label claim and recommend a specification.
Manufacturing & Quality Control
Raw seed inspection - fixed-origin seeds from Hebei/Shanxi/Shaanxi are identity-tested (TLC/HPLC) and screened for impurities.
Cleaning & low-temperature drying - removes foreign matter while protecting heat-sensitive saponins.
Milling - seeds are ground to a uniform particle size for efficient extraction.
Extraction - food-grade ethanol-water extraction at controlled temperature (below 65°C).
Filtration & concentration - the extract is filtered and concentrated under vacuum.
Macroporous resin purification - enriches the saponin fraction toward the 2% specification.
Spray drying - concentrate is atomized into a stable, free-flowing powder in a clean workshop.
QC release & packaging - HPLC assay, heavy metals, microbiology and pesticide testing before release.
product Benefits
1. Supports healthy sleep quality
Jujuboside A, the primary saponin, modulates GABA-A receptor subunit expression (α1, α5, β2) in hippocampal neurons, enhancing the brain's natural inhibitory signaling — the same pathway targeted by conventional sedatives, but through a gentler, non-addictive mechanism.
Human evidence:A randomized controlled study in postmenopausal women reported significant improvement in sleep-quality scores with jujube seed supplementation (scores improved from 10.47 ± 2.97 to 6.22 ± 2.52, p < 0.001). A randomized double-blind trial combining jujube seed with Poria cocos and GABA in women with sleep disorders reported total sleep duration increased by ~12.96%. A 2023 systematic review and meta-analysis of randomized controlled trials also found statistically significant improvements in self-reported sleep quality for Suan Zao Ren preparations.
2. Promotes relaxation and helps the body cope with stress
Jujubosides exhibit anxiolytic-like activity in behavioral models and are associated with reduced stress responses (HPA-axis regulation, lowered cortisol in animal models). Human users commonly report a calming effect that supports unwinding before sleep.
3. Neuroprotective support
Jujuboside A has been shown to up-regulate neurotrophic signaling (BDNF/TrkB/CREB), improve synaptic plasticity, and reduce oxidative markers (MDA) and AChE activity in dementia-model mice. These findings are promising but remain primarily at the preclinical stage.
4. Cardioprotective potential
In isolated heart-cell models (H9C2), jujuboside A activated the PI3K/Akt/mTOR survival pathway and protected cells against isoproterenol-induced injury — an area of active research, not a human clinical claim.
5. Antioxidant and anti-inflammatory support
Extract components have been shown to modulate pro-inflammatory cytokines such as TNF-α and IL-6 and to scavenge free radicals, thereby supporting overall cellular wellness.
Case Study
All cases are anonymized industry application scenarios; no customer or competitor brands are disclosed.
Case 1 — North American dietary supplement brand (sleep-support capsules)
Needed a standardized ingredient with a guaranteed ≥ 2% jujuboside assay, full heavy-metal compliance, and consistent batch performance for a new sleep-support capsule line.
We supplied a carrier-free 2% standardized grade with lot-specific COA (UV assay + HPLC confirmation of jujuboside A+B), 80-mesh particle size for smooth capsule filling, and a 24-month stability statement.
The ingredient passed the customer's finished-product testing on the first qualification round; the account moved from sample to repeat bulk orders on a quarterly supply schedule.
Case 2 — European functional beverage developer (nighttime relaxation drink)**
Needed a clean-label, water-dispersible botanical for an alcohol-free evening drink with balanced bitterness and no sedimentation issues.
We provided a 2% grade with an adjusted particle-size profile, shared dispersion and foam data, and worked with the customer on an inclusion level (~0.5–1.0%) that preserved flavor and mouthfeel.
The beverage reached sensory targets and clean-label compliance; the developer now sources the ingredient under an annual supply agreement.
Case 3 — Southeast Asian contract manufacturer (gummies & tablets)
Challenge: Required a flow-friendly powder with flexible MOQ and local documentation support for fast launches across multiple finished formats.
We supplied the 2% grade in 25 kg drums with full documentation (COA/TDS/SDS, non-GMO, allergen statement, Halal-compliant production), plus formulation guidance for gummy heat stability.
Three finished SKUs were launched within one quarter using the same ingredient lot specification, with no quality deviations reported.
FAQ
Q: What specifications of jujube seed extract do you offer?
A:Our flagship grade is standardized to a minimum of 2% jujubosides A+B by HPLC, the market-standard specification for calming and sleep-support supplement lines. We also supply 10:1 whole-spectrum water extract. Custom standardization levels can be developed for volume commitments.
Q: What are the active compounds and how is 2% jujuboside measured?
A:The primary calming markers are the dammarane-type triterpenoid saponins jujuboside A (CAS 55466-04-1) and jujuboside B (CAS 55466-05-2), together with the C-glycoside flavonoid spinosin (CAS 72063-39-9). The 2% specification quantifies the combined content of jujubosides A and B by HPLC against reference standards, and every batch is released with a COA reporting the measured value.
Q: How is jujube seed extract produced?
A:Dried mature seeds of Ziziphus jujuba var. spinosa (mainly sourced from Hebei, Shanxi and Shaanxi provinces in China) are cleaned, low-temperature dried, milled and extracted with food-grade ethanol-water at controlled temperature. The crude extract is purified over macroporous resin to enrich saponins, concentrated under vacuum, then spray-dried into a free-flowing yellow-brown powder standardized by HPLC to 2% jujubosides.
Q: What research supports the calming mechanism of jujuboside?
A:Published animal studies indicate jujuboside A modulates GABAergic transmission. A 2025 study in the Journal of Ethnopharmacology (PMID 40354840) found jujuboside A shortened sleep latency in insomniac mice via GABAergic modulation of the paraventricular thalamus, and a 2025 rodent study (PMID 39770888) reported that Zizyphi Semen extract and jujuboside A prolonged sleep duration through GABA-A receptor-mediated chloride influx, without affecting locomotor activity. As with all botanical ingredients, effects in humans should be evaluated in your own formulation and any claims validated for your target market.
Q: Is this extract suitable for calming and sleep support supplement formulations?
A:Yes. 2% jujuboside jujube seed extract is a widely used botanical for calming, relaxation and sleep-support concepts in capsules, tablets, gummies, powders and bedtime teas. It blends well with GABA, L-theanine, lemon balm, chamomile, valerian root and low-dose melatonin. We can supply stability, solubility and compatibility data to support your formulation work, and recommend confirming serving-level regulatory requirements (e.g. novel food status in the EU) for your destination market.
Q: Do you provide COA and third-party testing reports?
A:Yes. Every shipment includes a batch-specific Certificate of Analysis covering the jujuboside assay (HPLC), heavy metals (Pb, As, Cd, Hg by ICP-MS), microbiology, residual solvents and pesticide residue screening against EU MRLs. Third-party testing by SGS or Eurofins can be arranged on request, and retained samples are kept for at least two years for traceability.
Q: What certifications does your jujube seed extract carry?
A:The product is manufactured and available with FSSC 22000, HACCP, Kosher and Halal certification. An organic grade certified to USDA NOP and EU standards can be supplied for projects requiring organic status. All certificates accompany the shipment documentation.
