Xi'an Natural Field Bio-Technique Co., Ltd., founded in 2005 in Xi'an High-tech Zone, dedicated to R&D, production, sales about the separation and purification of natural active ingredients, research and chiral separation of API& intermediates. Main products including natural ingredients, semi-synthetic components and derivatives, and advanced raw materials for cosmetics, food, beverage and other industries. After six years development, we own a purity workshop of 1,000 square meters, and a R & D test center of 800 square meters. Also hold extraction equipment handling 20 tons of raw material simultaneously. Thus ensure us the capability to meet the needs of pre-clinical studies at home and abroad. In order to help more drug development companies save cost, we introduced a large Axial Compression Preparative Chromatography , established chiral separation centers, and started the projects of hundreds advanced single ingredients in 2009. Meanwhile, we finished the configuration of Axial Compression Preparative Chromatography System, High Performance Liquid Chromatography, Gas Chromatography, Autoclave driven by magnetic head and other equipment responsible for researching and quality control. Moreover, we have won the operating procedures for endangered species of yew, and got the ISO9001 certificate.   Our products are divided into six major categories: 1.    Taxane series, annual output up to 50kg; 2.    Aloe Series, annual output up to 8 tons 3.    Rhubarb Series, annual output of 5 tons 4.    API & Intermediates, annual output of 2 tons; 5.    Hundreds of Natural Purity Single Ingredients; 6.    Standard Herbal Extract series. All of our staffs adhere to "Unity, Rigorous and Realistic". And pursue the goal of  continuous innovation and acting as customers"
