Saxifragaceae thick leafy Chinese cabbage Bergenia crassifolia (L.) Fritsch distributed in Xinjiang and other places. The medicinal part is its rhizome, which mainly contains bergenin, arbutin and organic acid. Bergenin is used to treat chronic bronchitis and gastritis, stomach and duodenal ulcers. Bear fruit is used to stop cough and treat urinary tract infections. The literature reported that the plant contained 2.6% bergenin. The authors extracted the bergenin by water extraction from the thick-leafed Chinese cabbage (collected in August 1980) in the Matai Mountains of Altay, Xinjiang, and the yield was as high as 4.5%. The extraction method is simple and practical, and has a high practical value.
