Chemical and pharmacological advances of study on Lysimachia / 中国中药杂志

The progress in the research of the chemical components and pharmacological activities of Lysimachia was reviewed. Lysimachia mainly contain flavonoids, saponins and phenolic acids, and some of the plants have been used in the treatment of fever, ulcers, diarrhea and as analgesic or anti-inflammatory agents. The plants of genus Lysimachia are widespread in China, so it is a singificants work to study their chemical ingredients and pharmacological activities.
