From the Chinese drug ‘Chin-Shin-Hu’ imported from Hong Kong, two tertiary bases were isolated. One is dendrobine, first isolated by H. Suzuki, et al.2) and the second is a new base which has not previously been reported in the literature, for which the name dendramine is proposed. The water soluble alkaloid was also examined and it was concluded that the quaternary alkaloid found in this drug is the N-methyl dendrobium salt. © 1964, The Pharmaceutical Society of Japan.
