beijing boyuan-hengsheng high-technology co., ltd. , located in zhongguancun known as he silicon valley of china? was founded in 2001 by dr. xionghui wei of peking university. it is a high-tech company with businesses in chemical engineering, environmental protection, biomedical engineering, information technology, and international trade. our team is committed, collaborative and innovative, with ninety percent of employees holding college, master, or doctorate degrees. the company has set up advanced basic research labs and r&d labs and invested jiangxi yongfeng boyuan industry co. ltd. moreover, it also developed many independent intellectual property rights patent technologies such as catalyzing method of gas desulphurization by biochemical fe-basic solutions (patent number: zl02130605.2) and catalyzing method of gas decarburization, desulphurization, and decyanation by fe-basic solutions (application number: 99100596.1) etc. beijing boyuan-hengsheng high-technology co., ltd. is mainly engaged in research, development, manufacturing and selling the products independently. at present, in chemistry and chemical engineering field, there are activated ferrous carbonate, ferric pyrophosphate, ferrous pyrophosphate, ferric hydroxide, ferrous hydroxide, and sodium sulfate etc. at the same time, the company is building a production line and equipments that in organic solvent media, phenols as original materials, catalyzed by complexed solid catalysts are oxidated into benzoquinone, hydroquinol and pyrocatechol, with the output of 10000 ton per year. after exploring by lab test, bench test and pilot-plant test, this method is proved to have the advantage of innocuity, no-contamination, high output and low cost. in natural products and biomedical engineering field, we have established a suite of equipments to extract mixed alkaloids 5 ton per year from natural plants. now we can also produce 10kg sanguinarine, 5kg chelerythrine and 6kg chelidonine respectively per year with the purity of above 99% . at the same time, we are rebuilding the production line to enlarge the output of the mixed alkaloids to 50 ton per year, and the output of sanguinarine, chelerythrine and chelidonine will be above to 50kg, 20kg and 30kg separately. now we are also trying to develop bactericides, disinfectors, pesticides and veterinary drugs with the above mixed or purified alkaloids, finally to develop anti-cancer drugs. registration date: nov 29, 2006
