Located in the biotechnology hub of Xi’an, Shaanxi Province, China, Shaanxi Diaries Biotech Co., Ltd. is a modern high-tech enterprise specializing in the research and development, production, and global distribution of plant extracts, natural raw materials, and functional ingredients for the health, food, and cosmetic industries. Our strategic localization allows us to source premium botanical materials directly from resource-rich mountains, converting raw elements into standardized, bioactive powders.
With deep technical expertise and advanced manufacturing capabilities, we are committed to providing high-quality, safe, and effective natural solutions to customers worldwide. Our products are widely used in dietary supplements, functional foods and beverages, cosmetics, personal care products, animal nutrition, and agricultural applications. Over the years, Shaanxi Diaries Biotech has built long-term partnerships with more than 5,000 companies across over 80 countries and regions, earning a strong reputation for reliability, consistency, and innovation in the natural ingredients industry.
Our core product range features plant extract powders, standardized herbal extracts, fruit and vegetable powders, botanical raw materials, and customized functional ingredient solutions tailored to customer requirements. Furthermore, we provide full-spectrum OEM/ODM services, including formulation support, capsule and tablet development, and private label packaging to help global brands accelerate their market entry.
The international dietary supplement landscape is shifting rapidly from general wellness concepts to targeted, clinically backed intervention. Global supply chain managers must stay ahead of regulatory demands, raw material scarcity, and emerging consumer desires for high bio-efficacy formulations.
Consumers demand to know the origin of every herb. Free from chemical solvents, non-GMO, and synthetic binders, natural botanical matrices like standardized herbal powders are replacing legacy chemical additives.
Formulators are pairing botanical compounds with essential co-factors (e.g., Vitamin D3 combined with K2 MK7, or L-citrulline-dl-malate for nitric oxide synthesis) to exponentially improve bioavailability and efficacy.
To bypass crop fluctuations and environmental pollution, advanced manufacturers utilize precision microbial fermentation to biosynthesize active molecules, achieving purity levels of 98%+ (e.g., Urolithin A).
Procuring botanical extracts and dietary raw materials internationally presents complex hurdles. As a leading manufacturer, Shaanxi Diaries Biotech addresses the three main barriers faced by global purchasers:
Many raw material buyers struggle with batch-to-batch inconsistency in active botanical markers. Shaanxi Diaries Biotech employs HPLC, GC-MS, and UV-Vis spectrophotometry to ensure that critical parameters, such as 99% Icariin or 98% Urolithin A, meet strict specification limits in every single batch.
With tightening FDA and EU regulatory frameworks, raw materials must satisfy strict limits for lead, arsenic, cadmium, mercury, and multi-pesticide screens. We execute rigorous third-party testing and internal QA verification, providing complete, transparent Certificates of Analysis (COA) for all bulk shipments.
Global logistics demand flexible processing times and quick customs clearance. Our state-of-the-art production base in Xi'an maintains high-capacity storage of dried herbs and raw active powders, ensuring continuous production capability and consistent lead times, even during crop off-seasons.
Operating under rigorous GMP compliance, our Xi'an-based facility is spread across 70,000 square meters. The plant integrates six automated plant extraction lines, professional mixing configurations, and multi-lane filling lines to guarantee pharmaceutical-grade processing.
Navigating regulatory frameworks requires detailed, comprehensive documentation. Shaanxi Diaries Biotech maintains a high standard of compliance, securing primary global certifications to facilitate seamless entry into strict markets across North America, the European Union, the Asia-Pacific region, and the Middle East.
Our quality management protocols regulate the entire production flow, starting from our raw material selection and moving through extraction, concentration, refining, and final packaging. Our modern quality testing center is equipped to analyze pesticide residues, solvent residues, microbiological activity, and heavy metals. This ensures every product fulfills both target market regulations and our customers' quality standards.

| Heavy Metals (Pb, As, Cd, Hg) | USP <233> / EP 2.4.20 | ICP-MS | Pb <0.5ppm, As <0.5ppm, Cd <0.1ppm |
| Pesticide Residues | USP <561> / EU Regulation | GC-MS-MS / LC-MS-MS | Compliant with FDA & EC Limits |
| Microbiology (Total Count) | USP <2021> / EP 2.6.12 | Plate Count Method | <1,000 cfu/g (Max limit) |
| Residual Solvents | USP <467> / EP 2.4.24 | Headspace GC-FID | Ethanol <5000ppm, Hexane <290ppm |
Shaanxi Diaries Biotech continues to develop its extraction and purification capabilities by investing in advanced processing technologies. Our roadmap includes integrating artificial intelligence to model extraction processes, improving energy efficiency, and optimizing active ingredient yields.
By partnering with local cultivation cooperatives in Shaanxi, we promote sustainable harvesting of raw botanicals. This supports biodiversity and establishes a traceable chain of custody from seed to final extract powder.
To reduce solvent usage, we are implementing enzyme-assisted and subcritical water extraction systems. These methods operate at lower temperatures, preserving sensitive bio-active components and minimizing our environmental footprint.
