Ursolic acid wins wide favor  with its remarkable insulation,anti-aging,anti-oxidation in the field of cosmetics.We already find it in a range of plants,such as glossy privet,pipaye,phoenix leaf and selfshel.Although glossy privet is the most authentic raw material,there are almost no manufacturers to extract ursolic acid from glossy privet for its high cost.It’s cheap and distributed widely,but the content and quality of ursolic acid in pipaye is not as good as that in phoenix.Consequently,manufacturers in China principally take phoenix as raw materials.

   Quality determines the price.The same though the spectifaction is,the price of ursolic acid differs greatly.The basic reason is that there is no statutory national standards.The raw materials,testing methods,working contions and mobile phase is very important in the production.Every factor will affect the quality of usrolic acid.For example, the content of ursolic acid is 25% tested with area normalization method,in contrast,the figure is 20% with external standard method.Regarding to the high-level ursolic acid,technical problems still exist,and final testing standard is of difference.Some manufacturers will inevitably provide inferior goods as superior ones,thus affecting the healthy development of this industry.According to herbridge.com,25% ursolic acid price is 300-380RMB/kg now.

   Manufacturers supplying ursolic acid are still prodominately located in Shaanxi province.Baoji Yongjia Biotechnology Co.,Ltd. has been specialized in ursolic acid for three or four years,almost exporting ursolic acid every month. Xi’an TonKing Biotech Co., Ltd. has been dedicated to the production of ursolic for two or three years. Liuyang ATA Natural Product R&D Co., Ltd.located in Hunan province, especially devoting to the high-purity plant's effective compositions, also supply ursolic acid(25%-98%).
