Compound C from codonopsis saponin has been identified as albigenic acid. It was not a genuine sapogenin but an acid-induced isomerisation product of echinocystic acid.

The purpose of this study was to investigate the antioxidant activity and tyrosinase inhibitory activity of Codonopsis lanceolata 50% ethanol extract, and its solvent fractions (n-hexane, ethyl acetate (EA), n-butanol, water). The main components of the EA fraction were qualitatively analyzed using UPLC Q-ToF/MS. Additionally, a quantitative analysis was performed using UPLC. As a result, the total polyphenol content was 113.36 mg gallic acid/g in the EA fraction, which contained the largest amount of the C. lancolata solvent fractions. Also EA showed the highest antioxidant activity than other fractions. The IC₅₀ of DPPH(2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity was 0.03 mg/mL and the IC₅₀ of ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate)] radical scavenging activity was 0.049 mg/mL. The EA fraction showed tyrosinase inhibitory activity than other fractions and especially inhibited monophenolase oxidase reaction higher than diphenolase oxidase reaction. The monophenolase oxidase inhibited 55% when the concentration of the EA fraction was 0.25 mg/mL. As a result of Q-ToF/MS analysis, it was confirmed that tangshenoside I and lobetyolin were the main components of EA fraction. Thus, these results suggest that C. lanceolata may be used as a potent source of cosmetic agents.

A cDNA clone (GenBank accession no. CF924621) homologous to aluminum induced protein gene was isolated and characterized from Codonopsis lanceolata (ClAIP). The ClAIP is 906 nucleotides long and has an open reading frame of 711 bp with a deduced amino acid sequence of 236 residues. The ClAIP shows high homology to A. marina (84%), G. hirsutum(83%), V. radiata (83%), A. thaliana (80%), B. nap us (78%) and T. aestivum (68%). The deduced amino acid sequence of ClAIP also has homology to the N-terminal end of plant Asn synthetase. This region does not contain the active sites of the enzyme and the significance of this conservation is currently not clear. To investigate the expression of ClAIP against several heavy metal stresses, we treated the sliced tap root of C. lanceolata with various heavy metals. The expression of ClAIP was increased by 25 uM $Al_2$(SO$_3$)$_4$ in proportion to incubation time and also increased by 50 uM CdCl$_2$.

This study aimed to investigate the effect of growth regulators on the formation of the organ in the in vitro propagation of diploid and tetraploid Codonopsis lanceolata, and gain the basic data for in vitro propagation of superior C. lanceolata. In the case of diploid C. lanceolata, the highestshoot formation (3.0) was observed at 0.5 mg·L^-1 addition medium with low IBA concentration. The shoot formation of tetraploid C. lanceolata was suppressed by addition of IBA. In the addition of lAA, the shoot formation of diploid C. lanceolata was slightly higher at 1.0 mg·-L^-1 addition medium than that of control group, whereas tetraploid C. lanceolata showed the highest number (5.4) from control group. In the case of NAA, the shoot formation of diploid and tetra C. lanceolata tended to decrease at higher concentration. In terms of BA addition, the shoot formation of diploid C. lanceolata was increased by the addition of BA, whereaswhile the growth of shoot was decreased by the addition of BA. In the case of tetraploid C. lanceolata, shoot was found to be formed by the addition of low concentration of BA, and the growth of shoot was inhibited with the higher addition concentration of BA. With the addition of kinetin, the shoot formation of diploid C. lanceolata was slightly higher than that of control group, and the formation of adventitious root was highest (5.3) in the control group. In the case of tetraploid C. lanceolata, the shoot formation was similar in all treatment groups, but the formation and growth of adventitious root were significantly lower than that of diploid C. lanceolata. In the case of TDZ addition, the shoot formation of diploid C. lanceolata showed the pronounced results at 5.0 mg·L^-1 addition medium, and the growth of shoot was inhibited by the addition of TDZ. The formation of adventitious root was 5.3 and 4.9 in the control group and 0.1 mg·L^-1 addition medium respectively. The formation of the shoot of tetraploid C. lanceolata showed better results with the higher concentration of TDZ, and the growth was better with the lower concentration of TDZ. The formation and growth of adventitious root were significantly slower than that of diploid C. lanceolata.

The proximate and amino acid composition of wild and cultivated Cynochum wilfordi, Codopsis lancolata and lxeris sonchifolia were analyzed. Cynochum wilfordi, had higher contents of sugar ascompared with Codonopsis lancolata and lxeris sonchifolia. Fats was 2-3 times higher in Cynochumwilordi then Codonopsis lancolata and lxeris sonchifolia. No significant difference in the contents wasfound between the open field root, spontanity and cultivated at 30'c in biotronroom at condonopsislanceolata. However, contents of protein was 12.8% in lxeris sonchifolia. Total amino acid were 1.5-1.8 times higher in lxeris sonchifolia. than Cynochum wilfordi and Codonopsis lancolata. The decresingorder of the amounts of amino acid infused from the Cynochum wilfordi samples was Glu, Arg, Asp,Leu, Pro, Lys, Codonopsis lancolata (Changdeuk) was Arg, Glu, Pro, Leu, Asp, Lys, Codonopsislanceilata(Chirisan) was Arg, Glu, Pro, Asp, Lys, Leu, Codonopsis lancolata(Yeanbeun) was Arg,Glu, Asp, Leu, Ser, Lys, and lxeris sonchifolia was Glu, Arg, Asp, Cys, Lys, Pro.
