Two alkaloids were isolated from an ether-soluble alkaloidal fraction of Panax ginseng. They were identified as 1-carbobutoxy-$\beta$-carboline and 1-carbomethoxy-$\beta$-carboline.

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 methanolic extract of Commelina communis (aerial part) showed antibacterial activity against a cariogenic bacterium, Streptococcus mutans OMZ 176. The active principles were identified to be $\beta$-carboline alkaloids, 1-carbomethoxy-$\beta$-carboline, norharman and harman, which were bactericidal in the minimal inhibitory concentration (MIC) of $100\;\mu{g/ml}$ against the strain.

$N_{9}$-Formylharman, 1-carbomethoxy-$\beta$-carboline and perlolyrine with an unidentified alkaloid ($C_{10}H_{13}NO_{2}$, $M^{+}$ 179.094) have been isolated from the fruits of Lycium chinense Miller (Solanaceae) and characterized on the basis of chemical and physical evidence.

The alkaloidal constituents of Commelina communis(Commelinaceae) were investigated. From the ether soluble alkaloidal fraction, three ${\beta}-carboline$ type alkaloids were isolated by chromatographic purification process. Their chemical structures were identified as $1-carbomethoxy-{\beta}-carboline$, norharman and harman from the physicochemical data, which were newly isolated from this plant.

원지(Polygala tenuifolia, Polygalaceae)에 함유되어 있는 ${\beta}$-carboline계의 알칼로이드를 HPLC를 이용하여 정량하는 방법을 검토하였다. 고정상으로는 RP-18 컬럼을 사용하였고, 이동상으로는 $CH_3CN$과 0.01M 인산완충액(pH=3.5)을 기울기 용리시켰으며, UV254nm에서 검출하였다. 알칼로이드 분획을 얻기 위한 전처리 방법으로 산, 염기 처리에 의한 용매추출법과 양이온교환수지(Amberlyst 15)를 이용한 고상추출법을 비교한 결과 양이온 교환수지를 이용한 방법에서 더 나은 크로마토그램을 얻을 수 있었으며, 정량 결과 원지 중 알칼로이드 함량은 각각 harman $2.8{\times}10^{-3}%$, norharman $1.7{\times}10^{-3}%$, 1-carbomethoxy-${\beta}$-carboline $1.3{\times}10^{-3}%$, 1-carboethoxy-${\beta}$-carboline $1.4{\times}10^{-3}%$, perlolyrine $3.3{\times}10^{-3}%$로 나타났다.

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.
