[Advances in studies on chemical compositions of Alismatis Rhizoma and their biological activities].

Alismatis Rhizoma is a traditional Chinese medicine, which was widely used in clinical prescriptions and proprietary Chinese medicine. Over 220 compounds have been isolated from it, including triterpenoids, sesquiterpenoids, diterpenoids, polysaccharides, nitrogen compounds, phenylpropanoids, flavones and sterides. The pharmacological studies show that Alismatis Rhizoma exhibits diuretic, anti-urolithiatic, anti-hyperlipidemia, antidiabetics, antitumor, antioxidative, anti-inflammatory, anti-complementary activities, etc. In this review, the chemical compositions and its pharmacological activities of Alismatis Rhizoma in recent 50 years were summarized. The authors hope to provide references for further study, development and utilization of Alismatis Rhizoma.
