The effect of wild vegetables such as Allium tuberosum, Allium monanthum, Sedum sarmentosum, Ixeris dentata and Capsella-bursa pastoris on hexobarbital induced hypnosis was tested in mice. Among them, the methanol extract of Allium tuberosum exhibited significant lengthening of the barbiturate hypnosis. When various fractions prepared from the methanol extract of the Allium tuberosum were administered, the chloroform, ethylacetate and butanol extracts caused a significant activity. Through systematic fractionation by $SiO_2$ column monitoring by bioassays, $1,2,3,4-tetrahydro-{\beta}-carboline$ 3-carboxylic acid from the butanol extract was isolated as one of the active principles of this plant.

This study is to establish the quality control method of Codonopsis Radix, the root of Codonopsis lanceolata (S. et Z.) Trautv. $1,2,3,4-tetrahydro-{\beta}-carboline-3-carboxylic\;acid$ (1) isolated from this plant was adequate as an analytical marker. Content of 1 in Codonopsis Radix, determined by HPLC, was $0.0012{\pm}0.0005%$ (n=13). Total ash was $5.0{\pm}2.7%$, and loss on drying was $11.9{\pm}1.3%$.

Fourteen compounds were isolated from the n-BuOH fraction of the roots of Aralia cordata (syn. = A. continentalis). Through spectroscopic method, the chemical structures were elucidated as: caffeic acid (1), protocatechuic acid (2), thymidine (3), uridine (4), methyl-$\alpha$-D-fructofuranoside (5), a mixture (3 : 1) of $\beta$-D-fructopyranoside and $\beta$-D-fructofuranoside (6), 1-methyl 1,2,3,4-tetrahydro-$\beta$-carboline-3-carboxylic acid (7), methyl-$\beta$-D-fructofuranoside (8), sucrose (9), 5-caffeoylquinic acid (chlorogenic acid) (10), 3-caffeoylquinic acid (neochlorogenic acid) (11), 4-caffeoylquinic acid (cryptochlorogenic acid) (12), 3,5-di-O-caffeoylquinic acid (13), and 1-kestose [$\beta$-D-fructofuranosyl-($2{\rightarrow}1$)-$\beta$-D-fructofuranosyl-($2{\rightarrow}1$)-$\alpha$-D-glucopyranoside] (14). Among them, compounds 5, 7, 8, and 10 - 14 were isolated from this plant for the first time.

Codonopsis radix, a root of Codonopsis lanceolata (S. et Z.) Trautv., is a source of the traditional medicine and health foods. However quality control method is not established yet. This research is to establish the standard for the quality control of Codonopsis radix. From the root of this plant, 1,2,3,4-tetrahydro-${\beta}$-carboline -3-carboxylic acid (1) was isolated. This alkaloid was adequate as a marker compound for quality control, since it is a unique constituent of Codonopsis radix. In particular, (1) was not found in Adenophorae radix, a common adulterants of Codonopsis radix. (omitted)
