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.

더덕은 예로부터 약용으로 사용 되어 왔으며, 더덕의 뿌리에는 약용으로 가치가 높은 여러 종류의 triterpenoid 사포닌이 포함되어 있다. 본 연구에서는 더덕의 모상근 생육과 methyl jasmonate (MeJA)처리에 의한 사포닌 합성의 효과를 연구하였다. 더덕 모상근에 MeJA를 처리한 결과 주사포닌인 lancemaside A, B, E의 축적은 MeJA 무처리 모상근 보다 약 15% 정도 감소하였다. 반면 마이너사포닌(foetidissimoside A와 aster saponin Hb)의 함량은 무처리 모상근 보다 약15% 정도로 증가하였다. 이 결과를 통해 MeJA처리가 triterpene 사포닌의 생산조절을 위해 사용될 수 있는 것으로 판단된다.

더덕(Codonopsis lanceolata)은 주로 한국, 중국 등 동아시아 지역에 재배되고 있으며, 더덕의 뿌리는 기침, 기관지염, 천식, 결핵, 소화 불량의 증상을 치료하기 위한 기능성 식품 및 전통 의학으로 사용되어져 왔다. 보고된 바에 의하면 phenylpropanoids, polyacetylenes, saponins, flavonoids와 같은 다양한 식물 천연물 성분들이 항비만, 항염, 항암, 항산화, 항미생물 활성과 같은 약리학적 작용에 관여한다고 보고되어 있다. MS기반 대사체학 분석을 이용한 주산지의 마커 성분을 선정하는 것은 다른 지역에서 재배된 약용 식물의 안전성뿐만 아니라 화학적 조성과 생물학적 효능의 변화와도 관련이 있기 때문에 부작용 없이 더덕의 유익한 효과만을 보장하는데 중요하다. 본 연구에서는 국내산 더덕의 주산지 특성을 구별하기 위해 UPLC-QTOF-MS를 기반으로 하는 대사체 프로파일링과 다변량 통계분석 기법인 PCA 분석을 수행하여 판별모델을 확립하였다. 그 결과 인제(강원도), 횡성(강원도), 무주(전라북도)의 3개 그룹이 PCA와 loading plot 분석결과 tangshenoside I, lancemaside A, lancemaside G는 더덕 주산지를 구별하기 위한 잠재적 대사체 마커들로 제안하였다.

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.

본 연구는 더덕 사포닌의 최적 추출 방법을 구명하기 위해 수행되었다. 추출 방법에 따른 lancemasides 함량을 조사하기 위해 환류 추출(MeOH, BuOH), 열수 추출(Hot water), 초음파 추출(ultrasonic bath (40 kHz; continuous irradiation, interval irradiation), ultrasonicator (20 kHz))을 실시하였다. 그 결과, 총 lancemasides함량은 ultrasonic bath (MeOH; continuous irradiation) 추출에서 가장 높았고, ultrasonic bath (water; continuous irradiation) 추출>ultrasonic bath (MeOH; interval irradiation) 추출>ultrasonicator 추출>열수 추출>메탄올 환류 추출>부탄올 환류 추출 순으로 높았다. 따라서 더덕 사포닌의 최적 추출 방법은 MeOH을 이용한 초음파(ultrasonic bath, 40 kHz) 추출이었고, 추출 전 시료 건조 방법은 동결건조보다 음건으로 건조하는 것이 lancemasides 추출에 더 효과적이었다. 또한 초음파 추출 시 추출 시간은 2시간, 추출 온도는 $64^{\circ}C$에서 추출 하는 것이 효과적임을 확인할 수 있었다. 따라서 초음파(ultrasonic bath)추출은 기존에 주로 이용하던 환류 추출 및 분획을 실시했을 때 보다 많은 양의 사포닌(lancemasides)을 추출할 수 있었다. 그리고 추출 시간과 온도와 같은 추출 조건에 따라 aster saponin Hb가 lancemaside류로 성분 변화가 일어나는 것을 확인하였다. 특히 추출 온도가 증가함에 따라 aster saponin의 함량이 줄어들고, lancemaside A의 함량이 증가하는 것으로 보아 추출 온도가 사포닌 성분 변화에 영향을 주는 것으로 사료된다.

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.
