A large amount of sucrose was isolated from the rhizome of Asarunt kooyanunt MAKINO var. nipponicum KITAMURA (yield 5.4%), and A. hexalobum F. MAEKAWA (yield 5.3%), Aristolochiaceae. Examining asthmatic activities by chemical stimulating method with SO_2 on both A. sieboldi MIQ. and A. kooyanum MAKINO var. nipponicum KITAMURA of Aristolochiaceae, the activity was recognized only in methanol extracts of the fresh rhizome of both Asarum species. The fresh rhizome of A. hexalobum was also studied to find the activity in the acidic amino acid fraction, from which L-pipecolic acid was isolated. But its weak activity and poor yield suggested the presence of another active principles. From asthmatic active fraction of the rhizome of A. hexalobum F. MAEKAWA, L-pipecolic acid and asparagine were isolated, and also Asp, Ala, Glu, γ-aminobutyric acid, Ser, Thr, Tyr, Val, Phe, Leu, Ileu and Gly were identified chromatographically.
