Abstract

Sixty-two samples of Asahinea chrysantha from different localities in the Soviet Union were analysed by TLC. Three different chemotypes are recognised, each with a different geographical distribution. The most restricted of the three is an usnic acid deficient chemotype (I), with atranorin, alectoronic and α-collatolic acids, which is chemically the same as A. scholanderi and A. kurodakensis. Chemotype II contains usnic acid in addition to the basic chemistry, and chemotype III is α-collatolic acid deficient and has the widest geographical range. A centre of speciation of Asahinea in Soviet Primorje or Japan is proposed.
