Beijing Boyuan-Hengsheng High-Technology Co., Ltd. is mainly engaged in research, development, manufacturing and selling the products independently. 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.
