• 来歴

  In 1960, Nair et al. isolated hyperin from redosier dogwood, in which its content is 0.075%. Flavonoids in the treatment of cardiovascular and cerebrovascular diseases play a pivotal role, among which rutin is a typical representative. Isoquetin mainly presents in the leaves of kumquat flowers and the oleander plant kenaf, and it can also be obtained by chemical synthesis. It shows an anti-inflammatory effect through the capillary permeability test and other animal experiments. It also has a toxic effect on the larvae of Chilohabala larvae. It is one of the active ingredients of Hypericum japonicum, which is used in the treatment of hepatitis because of its inhibition of the activities of hepatic enzyme.

• 使用

• 適応症

  This product is available in the British Pharmacopoeia (2017) and the European Pharmacopoeia (9.0th ed.).
  Monomeric compounds are currently used clinically. In clinical practice, hypericin is the main active ingredient of proprietary Chinese medicines, such as Acanthopanax capsules, of which Acanthopanax stem and leaf extract are the raw materials for the preparation. Xin’an capsules, prepared with hawthorn leaf extract, are rich in flavonoids, in which hyperoside, a kind of flavonoid, is one of the main components. Qi yue lipid-lowering tablets are prepared from the effective parts of Chinese medicinal herbs such as hawthorn (Nucleation) and Astragalus membranaceus. Flavonoid is one of the main active ingredients in hawthorn, in which hyperoside content is higher. Xinxuening tablets, containing ursolic acid, vitexin rhamnoside, hyperoside, citric acid, and others, is a preparation made from hawthorn and pueraria and other traditional Chinese medicines, in which hawthorn enhances the actions of the medicine.
