English English Engineered to meet the stringent food hygiene, heavy-metal threshold, and solubility parameters demanded by contract manufacturers in Kawasaki and the Kanagawa industrial corridor.
Tongkat Ali (Eurycoma longifolia Jack) root extract serves as one of Southeast Asia's most rigorously researched adaptogenic botanicals. For manufacturing entities situated in Kawasaki's advanced biotech district—such as King SkyFront and the Keihin industrial corridor—generic raw powders and unsubstantiated ratio claims (e.g., crude 100:1 or 200:1) no longer satisfy regulatory compliance or consumer efficacy expectations.
Our extraction factory utilizes industrial-scale counter-current multi-stage water extraction paired with resin column chromatography to consistently concentrate and isolate bioactive quassinoids. The primary marker compound, Eurycomanone, is standardized via High-Performance Liquid Chromatography (HPLC) alongside auxiliary bioactive compounds: 14,15-β-dihydroxyklaineanone, 6-dehydroxylongilactone, and glycosaponin complexes.
By preventing thermal degradation during spray drying, we preserve the quaternary glycosidic linkages responsible for bio-absorption. This provides Kawasaki formulation scientists with exceptional batch-to-batch homogeneity, ultra-low ash content, and predictable kinetics inside solid dose, sachet, and functional tonic applications.

| Eurycomanone (HPLC) | ≥ 1.0% – 2.0% | ≥ 5.0% – 10.0% |
| Glycosaponins | ≥ 40.0% | ≥ 50.0% |
| Polysaccharides | ≥ 20.0% | ≥ 30.0% |
| Loss on Drying | ≤ 5.0% | ≤ 4.0% |
| Heavy Metals (Pb, As, Cd, Hg) | ≤ 10.0 ppm | ≤ 3.0 ppm (ICP-MS) |
| Pesticide Multi-Residue | EU/Japan Compliant | Zero Detection (GC-MS/MS) |
| Aerobic Plate Count | ≤ 1,000 CFU/g | ≤ 500 CFU/g |
Strategically situated in the Keihin Coastal Industrial Zone between Tokyo and Yokohama, Kawasaki represents Japan's epicenter of advanced clinical testing and functional life science engineering.
As Kanagawa Prefecture responds to demographic graying, functional product lines tailored toward healthy longevity and male vigor continue to accelerate. Tongkat Ali extract standardizes endocrine feedback pathways by optimizing free testosterone to sex hormone-binding globulin (SHBG) ratios. Japanese formulation chemists integrate our standardized extract with Pine Pollen, Zinc Yeast, and L-Arginine to produce next-generation vitality capsules manufactured under strict cGMP protocols in Kawasaki cleanrooms.
Athletic performance laboratories operating within King SkyFront (Kawasaki Innovation Gateway) are investigating ergogenic phytotherapy to combat sarcopenia and athletic fatigue. Standardized eurycomanone accelerates cellular ATP synthesis and reduces circulating cortisol post-exertion. Our micro-pulverized 80–100 mesh powders disperse smoothly into sports protein blends, BCAA recovery sticks, and energy gels without sedimentation or astringency issues.
Kawasaki boasts comprehensive packaging, bottling, and logistic hubs fronting Tokyo Bay. Our counter-current water extraction produces an instantaneously soluble, light brown Tongkat Ali extract powder optimized for functional tonics and wellness shots. With zero precipitation across acidic pH spectrums (pH 2.8–4.2) and high thermal stability during flash pasteurization, formulators create clear botanical drinks that satisfy modern clean-label demands.
Mastering compliance under Japan's Ministry of Health, Labour and Welfare (MHLW) regulatory framework ensures friction-free customs clearance and swift commercialization.
Japan's Consumer Affairs Agency (CAA) demands clinical substantiation for functional labeling (Kinō-sei Hyōji Shokuhin). Leading dietary supplement enterprises in Kanagawa require validated active compound tracking rather than generic ratios. BKYULA Biotech supplies high-resolution HPLC chromatograms, botanical origin certificates, and molecular stability documentation to streamline institutional filing procedures.
Japan implements an uncompromising "Positive List System" enforcing a default uniform limit of 0.01 ppm for agricultural chemical residues without specific tolerances. Our manufacturing facility screens all raw Eurycoma longifolia roots via GC-MS/MS and LC-MS/MS multi-residue panels before processing, certifying that shipments arrive entirely free of non-permitted organochlorine and synthetic pesticides.
Classification under Japan's Pharmaceutical and Medical Devices Agency (PMDA) separates medicinal ingredients from health food commodities based on the "Non-Drug List" (Hikiyakuhin List). Tongkat Ali root extract is legally permitted in conventional food and supplements as long as medicinal or pharmacological efficacy claims are avoided on primary consumer labeling, preserving broad commercial accessibility.
Six closed-loop production phases audited onsite by SGS Group guarantee consistent potency, zero residual solvents, and rapid release testing.
Sourcing mature wild-harvested roots from designated Southeast Asian rainforest reserves. Thin-Layer Chromatography (TLC) botanical identification ensures exclusion of counterfeit wood species.
Low-temperature pressurized deionized water extraction cycles isolate water-soluble quassinoids while preserving heat-sensitive bitter glycosides and active polypeptide chains.
Centrifugal clarifiers remove coarse cellulose debris before macroporous adsorption resin columns concentrate eurycomanone to target assay thresholds (1.0%, 2.0%, or 10.0%).
Evaporating moisture under moderate vacuum conditions (≤50°C) ensures zero thermal caramelization or breakdown of active phytochemical linkages.
Drying within class 100,000 cleanrooms using sanitized air filtration. Fluidized pulverization yields free-flowing fine powder passing 80 to 100 mesh standards.

Every commercial batch destined for Japan undergoes testing for heavy metals (Lead ≤2.0ppm, Arsenic ≤2.0ppm, Cadmium ≤1.0ppm, Mercury ≤0.1ppm via ICP-MS), aerobic plate count (≤1000 cfu/g), and coliform bacteria (Negative). We supply complete batch test data, manufacturer process flowcharts, and TSE/BSE-free declarations required by Japan quarantine stations.
Our Tongkat Ali Root Extract is typically cleared under HS Code 1302.19.00 (Vegetable saps and extracts; other). For custom blended powders or OEM formulations containing carrier maltodextrin, classifications under HS 2106.90 can be pre-arranged in cooperation with your customs broker.
Yes. While our standard specification is 80–100 mesh, we operate dedicated pharmaceutical-grade pulverizers and air classifiers capable of delivering ultra-fine 120 to 200 mesh powders. This guarantees smooth encapsulation kinetics and minimal machine jamming in high-speed rotary capsule filling equipment used across Kanagawa contract plants.
