더덕은 뿌리를 약용 또는 식용으로 이용하고 있으며 최근 더덕 추출물의 약리효능이 각인되면서 기능성 식품의 원료로서 흥미를 끌고 있다. 따라서 본 연구는 더덕의 주요한 사포닌인 lancemasides의 추출방법을 확립하고, UV (A, B, C) 처리와 발효(5종의 유산균 및 효모) 처리를 통해 더덕의 사포닌 함량을 증대시키고자 수행하였다. 추출방법은 autoclave를 이용한 열수 추출방법이 기존의 초음파 추출방법보다 추출 효율이 더 우수하였다. 더덕의 사포닌 함량을 증대시키기 위해 수확한 더덕 뿌리에 UV 처리와 발효 처리를 한 결과 UV 및 발효 처리는 각각 무처리에 비해 사포닌 함량이 약 20%, 22% 증가한 UV-C와 Bacillus subtilis 처리가 가장 효과적이었다. 또한 UV-C 처리의 경우 수확한 더덕 뿌리에서보다는 생육 중인 더덕 잎에 처리하는 것이 효과적이었다. 그러므로 더덕의 사포닌 함량은 생육 중인 더덕 잎에 UV-C 처리 후, 수확한 뿌리에 B. subtilis 발효 처리를 통해 87%까지 증대시킬 수 있었다. 이것은 UV-C 처리는 스트레스 초기에 반응하는 사포닌류 생성에 관여하고 발효 처리는 사포닌의 상 전환에 관여하여 사포닌 함량을 증대시키는 것으로 판단된다.

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.

Background: To obtain useful cosmetic resources, this study aimed to determine the non-saponin fatty acid and inhibitory activities of collagenase and elastase by treatment of Saccharomyces cerevisiae in supercritical fluid extracted oil of the adventitious root culture of wild mountain ginseng. Methods and Results: We performed supercritical fluid extraction at various conditions such as pressure, temperature, time, and use of co-solvents, unlike the n-hexane extraction for the adventitious roots culture of wild mountain ginseng. The non-saponin-fatty acid obtained from the oil of the adventitious roots culture was incresed by treatment with S. cerevisiae. The supercritical fluid extraction was conducted using gas chromatography. Non-saponin-fatty acid content, in the oil of adventitious roots culture of wild mountain ginseng treated with S. cerevisiae for 2 days were three times higher than that in the control. In addition, the oil of the adventitious roots culture treated with S. cerevisiae was investigated for the anti-wrinkle effect by using collagenase and elastase. The oil of adventitious roots culture treated with S. cerevisiae exhibited higher collagenase and elastase inhibitory activities than those in the control. Conclusions: Supercritical fluid extracted oil of the adventitious roots culture of wild mountain ginseng treated with S. cerevisiae was found to have decreased ratio of saturated fatty acids and incresed ratio and content of unsaturated fatty acids increased. Furthermore, it showed anti-wrinkle effects in vitro.

Background : Codonopsis lanceolata is currently used as vegetable, as well as materials for traditional medicines. However, consumers have nagative views on using pesticides and chemical fertilizer in C. lanceolata cultivation. Therefore, this research was conducted to select the appropriate organic fertilizer to improve the growth and saponin components of C. lanceolata by some organic fertilizers application. Methods and Results : Organic fertilizers were applied as 4 types: mixed organic matter, fermentation cake, bacterial culture and rice husks, excluding conventional chemical fertilizer and non-treatment used as control. The result analyzed in soil after fertilizer application showed that soil pH was acidified in fermentation cake and chemical fertilizer treatment, especially, chemical fertilizer treatment showed very high phosphoric-acid content than other treatments, and total N content was higher in fermentation cake, mixed organic matter and chemical fertilizer. Growth of C. lanceolata showed superior tendency in the treatment of mixed organic matter and fermentation cake. Lancemacides could be identified as foetidissimoside A, lancemaside A, lancemaside B, and lancemaside D. However, among them, quantitative analysis could not be conducted on foetidissimoside A due to its very low content, and lancemaside A was the most abundant saponin in the root from all the treatments. The content of lancemaisde A according to organic fertilizer application showed the highest value in the treatment of mixed organic matter, followed by the fermentation cake, bacterial culture, non-treatment, rice husks and chemical fertilizer, in that order. The content of lancemaside B and D was very low compared to lancemaside A, and there was no difference among treatments. Conclusion : The growth of C. lanceolata was superior in application of mixed organic matter and fermentation cake, and the major saponin, lancemaside A, was also increased.

Background : Platycodon grandiflorum radix used as a therapeutic agent for lung and respiratory diseases in traditional Korean medicine. The saponin and sugar content in P. grandiflorum root is dependent on the drying temperature and method. In this study, we investigated saponins and antioxidant contents in dried P. grandiflorum roots either not cut or cut to different lengths. Methods and Results : P. grandiflorum roots were either cut to 0.5, 1.0 or 2.0 ㎝ in length or left uncut. They were dried at 45℃ and the effect of antioxidant substances, antioxidant ability, and saponin content were investigated. P. grandiflorum roots rapidly dried out when cut to short lengths. The saponin contents (platycodin D, polygalacin D, and deapioplatycodin D) was highest in the uncut P. grandiflorum roots. When the cut lengths were long, the levels of polyphenolic compound increased. However, 2,2'-azinobis- 3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities were higher in the samples cut to shorter lengths. Conclusions : These results suggested that the saponin and antioxidant content of P. grandiflorum roots could be maximized by controlling the drying rate of the roots via adjustments to the root cutting length.

Various saponins are present in soybean seed, and they can be divided into three groups, group A, B and E saponin, in which the aglycone are soyasapogenol A, B and E, respectively. Group A saponins are supposed to be responsible for the undesirable bitter and astringent taste, and Group B saponins including 2,3-dihydro-2,5-dihydroxy-6-methyl- 4H-pyran-4-one (DDMP)-conjugated soyasaponins have the health-contributing activities. This study was conducted to investigate the saponin composition and content of 69 Korean cultivars. Thin-layer chromatography (TLC) and High-performance liquid chromatography (HPLC) were used to analyze the composition and content of soyasaponins. The composition of saponins in the seed hypocotyl of 69 Korean cultivars were divided into three groups, Aa, Ab and AaAb types. The numbers of Aa, Ab and AaAb types were 10, 36 and 23, respectively. The contents of group A saponin (Aa, Ab and Ac), group B saponin (non-DDMP, Ba and Bb) and DDMP saponin (αg and βg) ranged 21.7 ~ 57.0mg/g, 1.4 ~ 5.1mg/g and 9.8 ~ 27.4mg/g, respectively. A total of saponin content of seed hypocotyl in 69 Korean cultivars ranged from 43.8mg/g to 85.3mg/g with an average of 59.1mg/g.

본 연구는 백삼 추출액의 사포닌 함량을 높이고 품질과 관련된 특성을 증진 시킬수 있는 최적 추출 시간 및 온도를 밝히기 위하여 실시되었다. 백삼의 물 추출액의 총 ginsenosides 함량은 75℃ 에서 18시간 추출액 8.32 mg/10ml, 85℃ 에서 6시간 추출액 5.93 mg/10 ml, 95℃ 에서 6시간 추출액 4.92 mg/10 ml으로 최고의 함량을 나타냈다. 항당뇨 작용을 나타내는 ginsenoside Rb2 와 Re을 합한 최고 함량은 75℃ 에서 18시간 추출액 1.76 mg/10 ml, 85℃ 6시간 추출액 1.34 mg/10 ml, 95℃ 6시간 추출액 0.56 mg/10 ml이었으며, 항암 작용을 나타내는 Rg3 의 함량은 75℃ 에서 36시간 추출액 1.67 mg/10 ml, 85℃ 에서 36시간 추출액 3.13 mg/10 ml, 95℃ 에서 24시간 추출액이 3.56 mg/10 ml이었다. 추출온도와 시간에 따른 이화학성의 변화는 추출온도가 높을수록, 추출시간이 길어질수록 pH는 낮아 졌으나 환원당, 탁도, 당도는 증가하였다. 따라서 백삼추출액을 제조할때 1차 추출에서는 사포닌 최고 함량 추출 온도와 시간으로 추출한 다음 다시 온도를 높게 2차 추출 하여 맛을 증진시켜 혼합하는 방법이 좋을 것으로 생각된다.
