Abstract: Rhodiola L.which contains more than 90 species grows quite widespread all over the mountainous areas of northern hemisphere,of which 73 species are found in China.The roots of Rhodiola L.,one of the important traditional Chinese herbal medicines,possess the effects of anti-viral,anti-tumor,anti-aging,anti-oxygen deficiency,anti-fatigue,anti-radiation and other pharmacological properties.This paper sums up the update results of chemical composition and pharmacological properties of this plant,analyses the problems in the process of utilization,and discusses the strategies to solve the problems. Over 30 species of Rhodiola L.have been researched and pre-tested.There are 9 kinds and more than 60 new chemical compounds being separated and identified from them.Three problems should be solved in the process of utilization of these plant resources.The first one is the conflict between the scale exploitation and protection of ecological environment;the second is the endangered state of the plant resulted from the characteristics of reproductive ecology and human disturbance;the last is lack of the germ plasm resources evaluation system of the plant and of environmental synthesized mechanism of major pharmacological composition.Meanwhile,according to these questions,the authors think that it should build the germ plasm resources stocks of Rhodiola L.at national level,to screen and evaluate the value of different Rhodiola L.species using the core quality characteristic indicators,to research the law of producing and accumulating of the major secondary metabolites in culture,and to create the technological criterion of scale exploitation.
