Abstract
The invention belongs to the technical field of medicines, and particularly relates to a medicine for protecting the liver. The medicine for protecting the liver comprises the following components: 10%-35% of a kaurane diterpene compound (I)shown in the specification, 10%-35% triterpenoid (II) shown in the specification and the balance of a pharmaceutically acceptable carrier, wherein the sum of the percentages of the kaurane diterpene compound (I) and the triterpenoid (II) is 35%-70%. An in vitro test proves that the medicine is capable of relieving ischemia reperfusion injuries of human hepatocytes and playing a role in protecting the hepatocytes.
Description
technical field [0001] The invention belongs to the technical field of medicines, in particular to a medicine for protecting the liver. Background technique [0002] Xanthocerassorbifolia Bunge is a plant of the genus Xanthocerassorbifolia in the family Sapindaceae. It is a single genus and a single species. It is distributed in the hills and slopes of Northeast my country, North China, Shaanxi, Gansu, Ningxia, Anhui, Henan and other places. It is also often cultivated in various places. It is also recorded in "Compendium of Materia Medica". [0003] Xinguo is a rare woody oil-bearing plant unique to my country. It is known as camellia oleifera in the north. Because its kernels are rich in fatty oil, its mass fraction is as high as 52%, and it has high economic value. In addition to being used as an oil tree species, the plant also has good medicinal, edible, and ornamental values. The stems and branches of xanthus sorbifolium (Xieguanmu) are sweet, slightly bitter, and co...
