STUDIES ON AN ANTIASTHMATIC PRINCIPLES OF GNETUM PARVIFOLIUM

An antiasthmatic principles, Gnetum alkaloid hydrochloride C₁₆ H₁₈ NO₃ CL m. p. 265～266℃ was isolated from the stem of Gnetum parvifolium (Warb.) C.Y. Cheng (in Fujian).According to its spectral data (UV, IR, NMR and MS)and elemental analysis, Gnetum alkaloid hydrochloride was identified as dl-demethylcoclaurine hydrochloride (1-(p-hydroxybenzyl)-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline hydrochloride).
