Isolation and Characterization of Oleanolic and Ursolic Acids

The plant (whole plant) used for the present study is collected from Wulabo of Urumqi, Xinjiang province. Plant materials are further identified by Yonghe Li, a Pharmacist from Chinese medicine hospital of Xinjiang. Oleanolic acid and ursolic acid are obtained from National Institute for The Control of Pharmaceutical and Biological Products, 110709-200304110742-200516. HPLC grade Methanol supplied by USA, Fisher Scientific, 201-796-7100. Potassium phosphate monobasic of analytical grade is obtained from Tianjin, Tianxin chemical reagents company. All reagent solutions and buffers are prepared with water from Millipore Q3 ultra-pure water system (Millipore, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
