본 연구에서 금잔화(Calendula arvensis)에 대한 다양한 생리, 화학적 활성을 시험하여 기능성소재 가능성을 검토하였다. 금잔화 추출물은 낮은 세포독성을 나타냈다. 세포독성이 거의 없는 농도에서 금잔화 추출물 처리 시, 산화방지 활성, tyrosinase 활성저해 및 멜라닌 함량 저하를 보여주었다. 금잔화 추출물 농도에 따라 tyrosinase 단백질 발현이 억제되었으며, 이는 금잔화 추출물이 tyrosinase의 활성 및 단백질 발현을 억제시키거나 혹은 멜라노좀 수송 저해 등 다른 요인에 의해 멜라닌 합성을 저해하는 것으로 생각된다. 또한, 금잔화 추출물 처리 시, 항균활성이 나타남을 확인하였다. 따라서 금잔화 추출물은 향후 기능성 소재에 활용할 수 있는 효과적인 물질이 될 수 있다고 판단된다.

In this study, an on-site survey was conducted around Gasado island at Jodo-myeon, Jindo-gun, Jeonnam during July 2 to 25, 2002. The naturalized plants investigated in the surveyed sites were revealed 15 families and 39 species, including Althaea rosea and Oxalis articulata, which are ornamental plants. Only 10 species appeared in Imjado island among the surveyed sites the surveyed sites and Imjado Island, including Elymus sibiricus, Lolium perenne, Chenopodium album, Oxalis articulata, Oxalis corymbosa, Oenothera odorata, Xanthium strumarium, Bidens frondosa, Ambrosia artemisiaefolia var. elatior, and Taraxacum officinale. 6 species were distributed only in Gasado island, Jindo-gun, which included include Festuca myuros, Chenopodium ambrosioides, Amorpha fruiticosa, Malva neglecta, Calendula arvensis, and Carthamus tinctorius. 18 species were showed in Soheuksan island.; Yeosu area, 29 species; Imja Island in Sinan-gun, 34 species, and Gasado Island in Jindo-gun revealed 39 species. It is believed that the species of naturalized plants have been expanded compared to the other areas because of close location to the inland and large population fastiy. The Urbanization Index(UI) of this area was found to be 19.5. The naturalized plant communites in these surveyed sites were classified into Rumex crispus, Elymus sibiricus, and Lolium perenne community according to the vegetation table. Furthermore, they formed a community around areas that received great artificial influence from human dwellings or roads due to the characteristics of species distribution

현대사회에서 스트레스, 환경오염 등으로 인하여 중년남성의 전유물로 여겨져 왔던 탈모가 젊은 사람들에게서도 나타나며, 탈모로 고민하는 인구가 약 700만 명 이상으로 추산되고 계속해서 증가하는 추세이다. 우리나라 탈모관련 시장은 현재 약 4조원 규모이며 지속적인 성장세에 있으며, 주로 한약재등 천연추출물을 혼합하여 제품화하였다. 본 연구에서는 어성초, 금잔화 70% 에탄올 추출물을 이용하여 천연발모제 소재화를 목적으로 섬유아세포, 모유두세포, 지방전구세포에 대한 세포독성 및 지방전구세포 분화를 통한 발모 효능을 확인하여 약용작물을 이용한 향장품 소재화를 시도하고자 한다. 섬유아세포에 각 시료에 대한 세포 독성을 확인한 결과는 어성초 70% 에탄올 추출물을 50, 100, $500{\mu}g/mL$으로 처리하였을 때 107.3%, 109.6%, 128.2%로 세포 생존율이 증가하였다. 모유두세포에 대한 각 시료의 세포 독성은 나타나지 않았으며, 모발의 생육을 촉진하는 혈소판에서 유래하는 성장인자를 분비하여 모발 재생에 효과를 나타내는 지방전구 세포의 지방 분화 확인 결과 금잔화와 어성초 70% 에탄올 추출물을 $10{\mu}g/mL$의 농도로 처리하였을 때 각각 104.3%, 103.9%의 분화율을 나타내었고, 어성초 출물의 경우 처리 농도의 증가에 따라 지방분화율이 유의적으로 크게 증가하였다. 본 연구를 통해 육모용 모발제품 소재 개발을 위한 생약초 자원들의 in-vitro 육모활성관련 실험 결과 어성초와 금잔화는 각 세포에 대한 독성을 나타내지 않았으며, 어성초 70% 에탄올 추출물은 지방전구세포를 자극하여 지방 분화를 유도하는 것으로 확인되었다. 이상과 같은 결과로 어성초와 금잔화 70% 에탄올 추출물은 탈모관련 향장품 개발 소재로 높은 가능성을 가지고 있는 것으로 생각된다.

The purpose of this study was to select herbaceous plants that can be used for presenting various views and biodiversity on the extensive rooftop greening. Experiment plots were constructed in July 2005 on the rooftop of the Administration Building in the Seoul Women's University. For this experiment, planters were used to design rooftop greening. The size of a planter is 500mm${\times}$500mm${\times}$100mm and each planter has the water storage plate in the lower part of it. The soil was constructed by mixing pearlite, vermiculite, cocopeat, and leaf mold in the ratio of 6 : 2 : 1 : 1. The plot was divided into the watered plot and the dry plot. Since each plot was constructed 2 times, finally 4 planters were constructed in total. One hundred species were used for the experiment and 9 plants per species were planted in each planter. Plants were organized according to types of plants and the experiment used 86 native herbaceous plants, 6 herbs, and 8 foreign plants. The plots were monitored once a month, from July to November 2005. The length and width of plants were tape-measured and covering rate was calculated by CAD program. "SPSS 10.1" was used for a statistical analysis. The result showed no significant difference between the watered plots and the dry plots. In cases of some plants, there were statistically significant differences between the watered planter and dry planter such as follows : Astilbe chinensis and Polygonatum odoratum which are shade plants were measured as the highest value on the watered pots, and Aquilegia buergeriana, Chrysanthemum zawadskii, Calendula arvensis and Gypsophila cerastioides D.Don which are sunny plants were measured as the highest value on the dry plots. According to the final analysis of the data collected and observed for growth condition during the first year of the research, 51 species including Prunella vulgaris var. lilacina and Veronica linaiaefolia in native herbaceous plant, 5 species with Lavandula angustifolia in herbs, and 3 species with Lantana camara and Muscari armeniacum in foreign plants showed the highest growth condition. In conclusion, it is suggested that various plants including sedums could be effectively used for extensive rooftop greening to improve landscape(a view) of the rooftop and increase ecological values.
