Abstract: Snow lotus is a medicinal plant with a wide range of pharmacological activities. It has been used to treat rheumatoid arthritis, cough with cold, stomach ache, dysmenorrhea, and altitude sickness in traditional medicine. This review summarizes the bioactive components in six species of snow lotus including flavonoids, lignans, phenolic compounds, phenylpropanoids, and sesquiterpenes present in Saussurea involucrate (SI), Saussurea obvallata (SO), Saussurea laniceps (SL), Saussurea medusa (SM), Saussurea stella (SS) and Saussurea tridactyla (ST). We review the pharmacological and related molecular mechanisms by which these components exert antineoplastic, anti-inflammatory, and antioxidant effects and promote lipid catabolism, and provide a reference for the future study of the traditional Chinese medicinal chemistry and pharmacological activities of snow lotus.
