Overview

Sunflower Pharmaceutical Group Co., Ltd. (also known as Sunflower Pharmaceutical Group or Sunflower Pharmaceutical) is a large pharmaceutical group in the People's Republic of China, headquartered in Harbin, Heilongjiang. Its flagship enterprise, Heilongjiang Sunflower Pharmaceutical Co., Ltd., was founded in 1998 when Guan Yanbin acquired the assets of the Wuchang Pharmaceutical Factory in Heilongjiang. Its business subsequently expanded nationwide across mainland China, and it now has 26 controlled subsidiaries. Products such as Weikangling capsules, Hugan tablets, and Xiao'er Feire Kechuan oral liquid have a certain level of recognition in mainland China. Kuihua Pharmaceutical (葵花药业) is the commercial entity named in this dossier. The supplied material does not provide a company profile or establish its founding date, headquarters, ownership, leadership, or geographic reach. Its supplied website currently displays a notice that the site has been stopped by its administrator; that notice alone does not establish whether the company or brand is active or defunct. A separate evidence snippet contains general terminology about over-the-counter medicines, but does not explicitly connect those products to Kuihua Pharmaceutical. Accordingly, this entry does not attribute specific products, campaigns, corporate milestones, or market claims to the brand.

History

Heilongjiang Sunflower Pharmaceutical Co., Ltd., the flagship enterprise of Sunflower Pharmaceutical Group, was founded in 1998 when Guan Yanbin acquired the assets of the Wuchang Pharmaceutical Factory in Heilongjiang. Its business subsequently expanded nationwide across mainland China, and the group now has 26 controlled subsidiaries. The supplied evidence does not document the history of Kuihua Pharmaceutical. It provides no substantiated founding date, founder, ownership changes, product launches, expansions, or other dated company events. The official-site evidence is limited to a notice that the website has been stopped by its administrator. This is a statement about the website, not sufficient evidence to determine the operating status of the company or to construct a corporate history. A separate snippet provides generic over-the-counter medicine terminology without identifying Kuihua Pharmaceutical as the maker or seller of any named medicine. No product history or brand milestones are therefore included.

    Controlling shareholder Guan Yanbin sentenced to 11 years in first instance for intentional homicide

    In July 2020, Sunflower Pharmaceutical Group announced that its controlling shareholder, Guan Yanbin, had been sentenced to 11 years in prison in the first instance for intentional homicide, a case arising from a conflict with his ex-wife. The incident prompted discussion of corporate governance and controlling-shareholder risk. The criminal liability rests with Guan Yanbin personally and does not support any finding that Sunflower's products have quality problems.
