Explore our peerless range of high-purity botanical raw materials engineered for maximum bioavailability and therapeutic efficacy.
Avocado extract (derived from the fruit and seeds of Persea americana) is a powerhouse of bio-active lipids, fat-soluble vitamins, and sterols. At the center of clinical research is Avocado Soy Unsaponifiables (ASU), a natural vegetable extract made from one-third avocado oil and two-thirds soybean oil.
Our extraction process isolation targeting specific unsaponifiable fractions—namely phytosterols (such as beta-sitosterol, campesterol, and stigmasterol)—displays remarkable efficacy in down-regulating inflammatory cytokines like interleukin-1 (IL-1) and stimulating collagen synthesis in chondrocyte cultures.
Unlike standard crude oils, our standardized Avocado Extract contains high concentrations of active unsaponifiable compounds. We ensure that the molecular integrity of these volatile fractions is completely preserved using advanced, non-thermal purification pathways.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB), is the China Leading manufacturer and exporter of herbal extracts and its derivatives for more than 20 years. TRB is a technology-based company that combines research and development, production, and international market sales.
TRB's rapid development and dedicated service in the plant extract industry over the years has been recognized globally, culminating in the 2026 "Global Biotechnology and Life Sciences Award" - ''Best Global Herbal Extract Provider 2026''.
TRB currently operates three state-of-the-art factories: one herbal extract factory, one bee product factory, and one dedicated animal extract facility. Our plants operate under rigorous regulatory systems, boasting certificates including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER.

Why global pharmaceutical and cosmetic giants trust TRB as their long-term supply chain partner in mainland China.
By optimizing direct sourcing partnerships with global avocado hubs and utilizing local domestic processing facilities, TRB ensures stable access to premium high-lipid cultivars, mitigating price fluctuations in international markets.
Our vertically integrated production framework reduces raw material waste, lowers operational costs, and simplifies customs logistics, passing significant cost savings directly to wholesale buyers.
Our plants are equipped with Low-Temperature Supercritical CO2 Fluid Extraction systems and multi-stage vacuum molecular distillation lines. This enables us to manufacture solvent-free, highly pure unsaponifiable fractions at an industrial scale.
The global natural extract market is experiencing a significant shift toward standardized plant-based lipid molecules. Consumer awareness surrounding natural joint therapy has propelled Avocado Soy Unsaponifiables (ASU) to the forefront of the orthopedic health sector.
In parallel, the cosmetic industry’s migration towards "clean beauty" and "dermaceuticals" has created high demand for botanical unsaponifiables. Unlike synthetic mineral oils, avocado phytosterols are highly bio-compatible with human sebum, providing deep cellular repair without blocking pores.
With strict international regulations on pesticide residues, heavy metals, and plasticizers, pharmaceutical buyers now prioritize certified manufacturers who can present comprehensive analytical sheets (HPLC, GC-MS) for every batch.

TRB is not just a supplier; we provide comprehensive raw material solutions to secure your market success.
Every brand has unique product goals. TRB offers custom titration of Phytosterols, tailored ratios of Avocado to Soy (e.g., custom 1:3 or 1:1 ratios), and solvent-free extractions to match your precise target specifications.
Raw oil-based extracts can be difficult to formulate in standard capsules or instant drink powders. Our advanced micro-encapsulation spray drying technology converts lipid fractions into stable, free-flowing, water-dispersible powders.
From the sourcing of avocados to the shipping container, each batch receives complete documentation, including pesticide assays, allergen statements, heavy metal analysis, and residual solvent reports to guarantee trouble-free customs clearance.
We work with international freight partners to offer customizable shipping schedules (FOB, CIF, DDP). Our dedicated inventory buffer system helps regular clients avoid raw material shortages during peak seasons.
