Abstract
An alkaloid, gentianine, was isolated from the domestic Gentianaceous plants, the root of Gentiana axillariflora LEV. ET VNT., root of G. scabra BUNGE, and the whole herb of Swertia japonica MAKINO, in respective yields of 0.15, 0.05, and 0.76%. By the use of paper partition chromatography, the presence of gentianine was detected in 9 out of 14 kinds of herbarium specimens of plants of this family (Table II).
