지리산에서 자생하는 5종(참나물, 꿩의비름, 함박꽃나무, 산오이풀, 배초향)의 식물을 선정하여 5월부터 9월까지 자생지에서 꽃이 활짝 개화한 상태에서 채집하였다. 채집한 식물은 전초는 추출하여 17종의 폴리페놀 성분을 분석하고 다음으로 꽃, 잎, 줄기, 뿌리를 분리하여 각 부위의 추출물로 DPPH, ABTS, 폴리페놀, 플라보노이드에 관한 실험을 진행하였던바 결과는 다음과 같다. 1. 지리산에 자생하는 5종의 식물에 함유된 폴리페놀 성분은 총 13가지였으며 그중 가장 많은 검출된 물질의 총 함량은 산오이풀로 126.2ppm이었으며 주 물질은 ellagic acid(=ELA) 122.4ppm이었다. 2. DPPH radical 소거활성을 살펴본 결과 산오이풀의 꽃, 줄기, 뿌리에서 가장 좋았으며 다른 식물에서는 꽃 추출물에서 좋은 소거활성도를 나타냈다. 3. ABTS radical 소거활성도가 가장 높은 것은 산오이풀 꽃 추출물에서 가장 높은 13.5㎍/㎖에서였고, 뿌리 16.8㎍/㎖, 잎 22.6㎍/㎖ 순이었다. 그 외 다른 식물에서는 그렇게 큰 ABTS radical 소거활성능을 확인할 수 없었지만 전체적으로 꽃 추출물이 다른 부위인 잎과 뿌리 추출물보다 좋았다. 4. 총 폴리페놀 함량은 가장 많은 것은 함박꽃나무는 잎에서는 161.4mg GAE/g으로 가장 많았고, 다음으로 함박꽃나무의 뿌리와 배초향 뿌리에서 가장 많은 130.0mg GAE/g이었다. 또한 가장 낮은 것은 산오이풀로 나타났다. 5. 총 플라보노이드 함량은 배초향의 뿌리로 186.2mg CAE/g, 꽃에서 166.9mg CAE/g, 잎에서 가장 낮은 116.1mg CAE/g이었다. 이상의 결과에서 나타나듯 산오이풀은 항산화 효능도 우수하며 폴리페놀 성분의 함량도 많아 앞으로 화장품 산업에 충분히 이용 가능할 것이라 생각된다. Five species of plants (Pimpinella brachycarpa (Kom.) Nakai, Hylotelephium erythrostictum (Miq.) H. Ohba, Magnolia sieboldii K. Koch, Sanguisorba hakusanensis Makino, Agastache rugosa (Fisch. & Mey.) Kuntze) native to the clean area of Mt. Jiri were selected. The collection period was from May to September 2021, and the five species plants were collected in their native habitats with flowers in full bloom. The collected plants were extracted with 70% EtOH and 17 kinds of polyphenol components were analyzed. Next, flowers, leaves and roots were separated from plants, extracted with 70% EtOH for each part and experiments were conducted on DPPH, ABTS, total polyphenols, and total flavonoids. The results are as follows. 1. There were a total of 13 polyphenol components contained in the 5 species of plants native to Mt. Jiri. Among them, the total content of the most detected substance was Sanguisorba hakusanensis Makino, which was 126.2 ppm, and the main substance was ellagic acid (=ELA), which was 122.4 ppm. 2. As a result of examining the DPPH radical scavenging activity, the flowers, stems, and roots of Sanguisorba hakusanensis Makino showed the best scavenging activity, while the flower extracts of other plants showed good scavenging activity. 3. The highest ABTS radical scavenging activity was Sanguisorba hakusanensis Makino flower extract at 13.5 ㎍/㎖, followed by roots at 16.8 ㎍/㎖ and leaves at 22.6 ㎍/㎖;. Although such a large ABTS radical scavenging activity could not be confirmed in other plants, the flower extract was overall better than the leaf and root extracts of other parts. 4. The highest total polyphenol content was found in the leaves of Magnolia sieboldii K. Koch, at 161.4mg GAE/g, followed by the highest content in the roots of Magnolia sieboldii K. Koch and the roots of Agastache rugosa (Fisch. & Mey.) Kuntze, at 130.0mg GAE/g. Also, the lowest was found to be Sanguisorba hakusanensis Makino. 5. The total flavonoid content was 186.2mg CAE/g in the roots of Agastache rugosa (Fisch. & Mey.) Kuntze, 166.9mg CAE/g in the flowers, and the lowest was 116.1mg CAE/g in the leaves. As shown in the results above, Sanguisorba hakusanensis Makino has excellent antioxidant efficacy and has a high polyphenol content, so it is expected to be fully utilized in the cosmetics industry in the future.

Five species of plants (Clerodendrum trichotomum Thunb., Angelica dahurica (Fisch. ex Hoffm.) Benth. & Hook. f. ex Franch. & Sav., Caryopteris incana (Thunb. ex Houtt.) Miq., Lonicera japonica Thunb., and Parasenecio auriculatus var. matsumurana Nakai) native to the clean area of Mt. Jiri were selected. The collection period was from May to September 2021, and the five species plants were collected in their native habitats with flowers in full bloom. The collected plants were extracted with 70% EtOH, and 17 kinds of polyphenol components were analyzed. Next, flowers, leaves, stems, and roots were separated from plants, extracted with 70% EtOH for each part and experiments were conducted on DPPH, ABTS, total polyphenols, and total flavonoids. The results are as follows. 1. It was found that there were a total of 8 kinds of polyphenols contained in 5 species of plants that are native to Mt. Jiri. Among the polyphenol components, chlorogenic acid was contained in 4 species of plants, and caffeic acid was contained in 2 species of plants. 2. As a result, the DPPH radical scavenging activity was the best in the stem of P. auriculata and the C. trichotomum was good regardless of the specific part. It was found that the activity-scavenging activity was good in the flowers of A. dahurica and the leaves of L. japonica. 3. The highest ABTS radical scavenging activity was C. trichotomum Thunb., whose EC₅₀ value was 38.73~66.28ppm. Next, the leaves and stems of L. japonica Thunb., A. dahurica and P. auriculata, and the leaves and stems of C. incana appeared in that order. 4. The highest total polyphenol content was 154.83mg GAE/g in the leaves of C. trichotomum, followed by about 130mg GAE/g in the flowers of C. trichotomum and P. auriculata. The lowest was 26.27mg GAE/g in the stems of A. dahurica.

Chemical preservatives have a good effect on antibacterial activity, but many side effects on the human body have been reported. Recently, the development of natural preservatives that are harmless to the human body and have preservative functions and self-efficacy is active. In addition, in order to increase the absorption rate of natural products by the human body, the method of fermentation using strains is also increasing. Therefore, this study selected varieties that are harmless to the human body and have good antibacterial activity. 1. The yield of origin, thickness and solvent was investigated. Scutellaria baicalensis Georgi was made in China and received a yield of 21.88% from 50% ethyl alcohol extract. Salvia miltiorrhiza Bunge was made in Korea and received a yield of 25.62% from 50% ethyl alcohol extract. Dryopteris crassirhizoma Nakai was made in China and received a yield of 6.50% from 70% ethyl alcohol extract. 2. The solid fermentation with the S. baicalensis and S. miltiorrhiza with B. Subtilis yield gained 24.40%, 39.30%, and D. crassirhizoma obtained 11.10% yield when fermented with L. casei. 3. After the liquid fermentation, a clear zone of 9mm was identified for the S. aureus strain in the S. baicalensis, and the antibacterial activity was not confirmed in S. miltiorrhiza and D. crassirhizoma. 4. When the S. baicalensis was fermented with L. Casei, it showed high antibacterial activity in C. albicans and S. aureus. S. miltiorrhiza showed antibacterial activity in S. aureus when it was solid with S. cerevisiae. When the spectators were solid with L. casei and S. cerevisiae, antibacterial activity was high in E. coli and S. aureus. Overall, the antibacterial activity after fermentation was much higher than when fermented. 5. The change in active ingredients was baicalin 101.57, baicalein 28.26, and wogonin 5.33mg/g in the S. baicalensis that did not ferment solid. When solid fermentation with S. cerevisiae, the content of baicalinin with baicalin 94.31, baicalein 30.41, and wogonin 3.57mg/g was found to have increased. S. miltiorrhiza that was not fermented, salvianolic acid A was 1.82mg/g, and when fermented with S. cerevisiae, it increased to 5.70mg/g. The active ingredients of the spectators were flavaspidic acid AP, flavaspidic acid PB, flavaspidic acid AB, and flavaspidic acid BB.

The experiment was carried out to investigate the effect of temperature of scaling cutting, parts of scaling from the parent bulb and cutting media on certain growing responses of Oriental lily hybrids. The results obtained as follows : 1.Temperature of scaling was the best at 25℃ in 'Casablanca' and 'Le Reve' but 'Stargazer' was the best 20℃ 2.Number of the bulblets per scale was greater with outer and middle scales than the inner scale in the parent bulb. 3.Cutting media of the scaling was preferable with sawdust for the bulblet formation.
