    Abstract:
    OBJECTIVE: To find the chemical diversity and characteristics of A. lancea on two levels--individuals and populations, and to discover the chemical essentials for forming geoherbs. METHOD: 47 rhizomes of A. lancea were collected in 7 populations, and 6 naphtha components (1. elemol, 2. hinesol, 3. beta-eudesmol, 4. atractylone, 5. atractylodin, 6. atractylenolid I) in the rhizomes were determined by GC-MS combination. Principal Component Analysis and Cluster Analysis were carried out by SPSS. RESULT: Cluster Analysis of the 6 main components indicated that the chemical components of geoherbs were different from those of the non-geonerbs of A. lancea. Other analysis showed as follows: 1. The general oil of geoberbs were lower than that of non-geoherbs(P < 0.01), but components yielding more than 1% (% of the total oil) were more than non-geoherbs(P < 0.01); 2. Hinesol mixing beta-eudesmol was more in non-geoherbs, which atractylodin mixing atractylone was more in geoherbs(P < 0.001); 3. Principal Component Analysis implied that atractylone was the most important component to discriminate geoherbs and non-geoherbs of A. Lancea. CONCLUSION: The naphtha composing characteristics of geoherbs was the special proportionment sale, viz. atractylone: hinesol: beta-eudesmol: atractylodin being(0.70~2.00):(0.04~0.35):(0.09~0.40):1.
