  • Over twelve alkaloids were detected in the ether-soluble alkaloid fraction of Panax ginseng roots. Among them, three alkaloids were identified as N9-formylharman, ethyl $\beta$-carboline-1-carboxylate and perlolyrine on the basis of chemical and spectroscopic studies. And also spinacine was isolated from the water-soluble fraction of the roots.

  • A new $\beta$-carboline alkaloid, 1-carbobutoxy-$\beta$-carboline as well as $N_{9}$ -formylharman, 1-carboethoxy-$\beta$-carboline, 1-carbomethoxy-$\beta$- carboline, perloyrine, harman and norharman were isolated from the rhizoma of Polygala tenuifolia Willdenow. The structures were elucidated on the basis of spectroscopic studies and chemical evidence.

  • The alkaloid components in the root of Codonopsis lanceolata were studied. From the ether soluble alkaloid fraction, four $\beta$-carboline alkaloids were isolated in crystalline state by chromatographic purification process; comp. I mp $178^{\circ}$, isolated yield 4.5$\times$$10^{-5}%$, comp. II mp $166^{\circ}$, 6.0$\times$$10^{-5}%$, comp. III mp $164^{\circ}$, 1.8$\times$$10^{-4}%$ and comp. IV mp $197^{\circ}$, 3.5$\times$$10^{-5}%$. They were identified by spectral analysis and by total synthesis as being a new component $N_9$-formylharman, and already known components in other plant 1-carbomethoxy-$\beta$-carboline, perlolyrine and norharman.
