Codonopsis lanceolata has numerous chemical constituents that includes polyphenols, saponins, tannins, triterpene, alkaloids, and steroids. The extract of C. lanceolata was partitioned with Haxane, CH₂Cl₂, EtOAc, n-BuOH and MeOH. The determination of structure for lancemaside G, lancemaside B, lancemaside A were based on physicochemical and HPLC chromatogram data, including NMR and HR-MS. In addition, tangshenoside I and lobetyolin were identified in the material separation process for the extract of C. lanceolata, and content analysis was performed using HPLC. The compounds were confirmed as lancemaside G, lancemaside B, lancemaside A, tangshenoside I, and lobetyolin.

Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of 3,28-bidesmosidic triterpenoid saponin with high medicinal values. In this study, we induced hairy root-derived transgenic plants of C. lanceolata and analyzed triterpenoid saponins from the leaf, stem and root. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. The saponins are lancemaside A, B and E, foetidissimoside A, and aster saponin Hb. Transgenic plants contained richer triterpenoids saponin than wild-type plants. Major saponin lancemaside A was the most abundant saponin in the stem from transgenic-plant, $4.76mg{\cdot}1^{-1}dry$ stem. These results suggest that transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.

The roots of Codonopsis lanceolata (Campanulaceae) contain several kinds of triterpenoid saponin with high medicinal values, which have been used in traditional medicines. This study investigates the impacts of methyl jasmonate (MeJA) - adding time on the saponin synthesis and the hairy root growth of C. lanceolata. A significant decrease in major saponin (lancemaside of three kinds) content of hairy roots was observed with MeJA treatments. Contents of lancemaside A, B and E decreased about 15% more than non-treated hairy roots. In contrast, minor saponin (foetidissimoside A and aster saponin Hb) accumulation was about 15% higher than the non-treated hairy roots. These results suggest that MeJA treatment could be used in the production of teriterpene saponins.

Codonopsis lanceolata (Deoduk) was grown in East Asia, including Korea, China, Japan, and Russia, and the roots of C. lanceolata have been used as functional foods and traditional medicine to treat symptoms of cough, bronchitis, asthma, tuberculosis, and dyspepsia. The phytochemicals of C. lanceolata have been reported such as phenylpropanoids, polyacetylenes, saponins, and flavonoids that are involved in pharmacological effects such as anti-obesity, anti-inflammation, anti-tumor, anti-oxidant, and anti-microbial activities. Selecting marker substances of the main producing area by MS-based metabolomics analysis is important to ensure the beneficial effect of C. lanceolata without side-effects because differences in cultivated areas of plants were related not only to the safety of medicinal plants but also to changes in chemical composition and biological efficacy. In our present study, ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry combined with multivariate statistical analysis was applied to recognize the main producing area of C. lanceolata in South Korea. As a result of Principal Component Analysis and loading plot analysis of three groups, Inje (Kangwon-do), Hoengseong (Kangwon-do), and Muju (Jeonlabuk-do), several secondary metabolites of C. lanceolata including tangshenoside I, lancemaside A, and lancemaside G, were suggested as potential marker substances to distinguish the place of main producing area of C. lanceolata.

Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of triterpenoid saponin with high medicinal values. In this work, we induced transgenic hairy roots of C. lanceolata and analyzed triterpenoid saponins from the hairy roots and hairy root-derived transgenic plants. Hairy roots were obtained from leaf explants by the transformation of Agrobacterium rhizogenes R1000. Transgenic hairy root lines were confirmed by the transcriptional activities of rolA, B, C, and D genes by RT-PCR. Transgenic root lines actively proliferated on hormone-free medium but not in nontransformed roots. Hairy roots contained richer triterpenoids (lancemaside A, foetidissimoside A, and aster saponin Hb) than nontransformed roots. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. They showed phenotypic alterations such as shortened shoots and an increased number of axillary buds and adventitious roots. The transgenic plants also contained higher triterpenoid levels than wild-type plants. These results suggest that hairy roots and transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.

Background: This study was conducted to investigate the effects of fertilization with the application of mixed organic matter after cultivating green manure crops on the growth and saponin content of Codonopsis lanceolata Trautv. Methods and Results: Five type of cultivation of green manure crops were done: hairy vetch as a single seedling crop (HV), hairy vetch and rye as a mixture of seedling (HV/R), additional fertilization with mixed organic matter after cultivation of a seedling mixture (HV/R/MO), chemical fertilizer (CF), and a non-treated control (NT). The total nitrogen content was the highest in the HV/R/MO treatment, followed by the HV, CF, HV/R and NT treatments, respectively. Nitrogen fixation was higher in the single seedling treatment with hairy vetch (HV) than in the treatment with a mixture of hairy vetch and rye seedling (HV/R). Moreover, the growth of C. lanceolata was greatly increased by the application of additional fertilizer after treatment with the mixture of hairy vetch and rye seedlings. The HV/R/MO treatment produced the highest total lancemaside content among the treatments, followed by HV, HV/R, CF, and NT, respectively. Conclusions: It was verified that C. lanceolata experienced superior growth with the application of mixed organic matter as additional fertilizer after the cultivation of green manure crops, and the content of its major saponins, lancemasides were also increased by this treatment.

This study was conducted to select the optimal extraction method of codonopsis lanceolata saponin. To investigate the lancemasides content depending on each extraction method, various extractions were performed: reflux (methanol and butanol), hot water, as well as ultrasonic bath (40 kHz; continuous irradiation/interval irradiation) and ultrasonicator (20 kHz) extractions. From the result, the overall lancemasides content were the highest in ultrasonic bath (MeOH; continuous irradiation) extraction, followed by ultrasonic bath (water; continuous irradiation)>ultrasonic bath (MeOH; interval irradiation)>ultrasonicator (MeOH)>hot water>MeOH reflux>BuOH reflux extractions in that order. Sample drying method prior to ultrasonic bath extraction was more effective shade drying than freeze drying. Effective duration and temperature of extraction was 2 hr at $64^{\circ}C$. And ingredient change diverted from aster saponin Hb to lancemasides was identified by extraction condition such as extraction time and temperature.

Codonopsis lanceolata, called deodeok in Korean, has been verified for various effects, including anti-aging and anti-inflammatory effects and insomnia improvement, and is one of the healthy foods that Koreans enjoy eating. In this study, the saponin content, lansemaside A content, and total saponin content of deodeok were analyzed using high-pressure sterilization and solid fermentation by mixed lactic acid bacteria. The antioxidant effect was compared to determine improved processing methods of deodeok. The lansemaside A content of deodeok samples depending on the preprocessing methods was analyzed: 2,594.10 mg/kg for dried deodeok, 2,100.93 mg/kg for steamed deodeok, and 1,151.31mg/kg for fermented deodeok. The total saponin content was found to be 7,209 mg/kg for dried deodeok and 8,605 mg/kg for steamed deodeok, showing a high saponin content. The total polyphenol content was highest for dried deodeok, steamed deodeok, and fermented deodeok. As for the antioxidant effect, it was analyzed that the effect of dried deodeok was the highest, followed by steamed deodeok and fermented deodeok; Dried deodeok had the highest value in total polyphenol content, not in total saponin content, which is considered to have a positive influence on its antioxidant effect. The content of lansemaside A was the highest for dried deodeok. When fermented deodeok is consumed, more beneficial effects on health can be expected by ingesting it with lactic acid bacteria cultured using saponins and polyphenols. Therefore, this study suggests the possibility of manufacturing products suitable for the needs of consumers, such as the flavor of deodeok, according to the processing methods.
