자원식물을 소재로 이용하는 생물산업은 21세기 경제성장을 주도할 핵심기간산업이며, 미래형 고부가가치산업이다. 현재 지구상에는 약 55만종의 식물이 존재하는 것으로 알려져 있으나, 인간의 손길이 닿지 않은 천연 강우림 등의 미개척지가 상당수 존재하고 있어 더욱 많은 종들이 존재할 것으로 추정된다. 자원식물들 중에는 작물로의 개발이 가능하거나, 개발할 필요성이 높은 식물들이 많이 있다. 자원식물들은 예로부터 식용, 약용, 관상용, 유지용, 기호용, 밀원용, 섬유용, 향신료용, 향료용, 당료용, 호료용, 염색용, 수지용, 탄닌용 등으로 구분되어 이용되어 왔다. 자원식물은 종에 따라 꽃, 줄기, 잎, 뿌리 및 종자 등 부위별로 다양하게 산업적 소재로 활용되어 왔다. 최근에는 건강에 관한 관심이 급증하면서 다양한 건강 기능성 상품이 개발되고 있으며, 관련 시장이 급속하게 성장하고 있다. 특히 자원식물 등 천연물을 소재로 한 건강 기능성 상품은 안전성이 보장되며 우수한 생리활성이 있는 것으로 밝혀지면서, 자원식물을 소재로 한 건강 기능성 상품의 개발에 대한 수요가 증가하고 있는 실정이다. 따라서 다양한 자원식물을 대상으로 이들의 활용가치를 분석하여 상품화할 수 있는 방법의 개발이 절실히 필요하다. 또한 주 5일제 실시 및 여가활용에 관한 관심이 급증하면서 농촌 경관산업에 대한 수요가 증가하고 있다. 농촌 경관산업은 국민의 여가선용 및 복지향상에 효과적일 뿐 아니라 지역주민과 관광객이 함께 즐길 수 있는 관광산업으로써 지역 이미지 강화를 통한 지역 홍보, 지역 내 일자리 창출 및 경관산업에 사용된 생물소재를 이용한 바이오산업의 활성화 등의 장점을 지니고 있다. 또한 농촌 경관산업은 자연과 농촌을 활용한 자연 친화형 관광단지를 조성하여 친환경, 고부가가치형 종합산업을 추구하는 추세이다. 그러므로 경관산업 및 이를 활용한 바이오산업의 소재로써 자원식물의 역할은 매우 클 것으로 생각된다. 특히 각 지역에 자생하는 고유의 자원식물을 활용하면 지역 특화 경관산업 및 바이오산업의 발전에 크게 이바지 할 수 있으며, 이로 인하여 지역 경제 활성화 및 친환경 건강 기능성 상품에 대한 수요를 충족시킬 수 있을 것으로 기대된다. 따라서 친환경 건강 기능성 소재 개발과 농촌 경관산업을 활용한 생물산업에 적용할 수 있는 산업적 가치가 우수한 자원식물의 다양한 기능을 분석하고, 각 자원식물별로 특성에 맞는 개발 방안을 구축하여 다양한 산업화의 소재로 활용하여야 할 것으로 생각된다.

Among natural products, the shells of black walnut(Juglans nigra), which are not used commercially and mostly discarded, were examined to investigate the physiological activity and the efficacy for the cosmetic application. DPPH radical scavenging activity of hot water extract of black walnut shells was 76.06% at 300 ㎍/mL. ABTS radical scavenging activity of the extract was 61% at 1000 ㎍/mL, showing excellent antioxidant activity. When the black walnut shell extract was applied to HaCaT cells, a skin keratinocyte, the viability of the cells was 92.6% at 250 ㎍/mL, showing a remarkably low effect on cell viability. At the concentration of 500 ㎍/mL, 67.35% of nitric oxide(NO) production was inhibited. It also showed an inhibitory effect on Hyaluronidase 31 times higher than that of Vitamin C at 100 ㎍/mL concentration. In conclusion, the black walnut shell extract showed high potentials for the cosmeceutical applications, suggesting the possibility of using it as a high value-added natural material in various industries such as food, fragrance, healthcare, and pharmaceuticals.

The purpose of this study was to investigate the effect of aromatherapy planned behavior on behavioral intention using the theory of planned behavior of attitude, subjective norm, and perceived behavioral control as factors of the theory of planned behavior. The behavioral intention of aromatherapy planned behavior was analyzed to have a significant positive causal relationship between the independent variables of attitude, subjective norm, and perceived behavioral control on the behavioral intention of aromatherapy. As a result of testing Hypothesis 1, "Aromatherapy planned behavior will have an effect on behavioral intention," previous research confirmed that the greater the attitude, perceived behavioral control, and subjective norm during aromatherapy planned behavior, the higher the participation intention. The verification was consistent with similar results between this study and this study. These results suggest that aromatherapy planned behavior will contribute to increasing aromatherapy's market share, reducing stress, and improving health through behavioral intention.

The characteristics of volatile flavor compounds of Fuji apples were compared by different extraction methods for information leading to a natural fragrance development. The volatile flavor components of Fuji apples were extracted using simultaneous steam distillation and extraction (SDE), solvent extraction (SE), and solid-phase microextraction (SPME) methods and then analyzed by gas chromatograph-mass spectrometer. A total of 66, 32 and 54 components were identified in SDE, SE and SPME extracts, respectively. (E,E)-$\alpha$-Farnesene, hexanol, butanol, 2-methyl butanol, hexyl hexanoate, hexyl 2-methyl butanoate, hexyl butanoate, and butyl hexanoate were the major flavor components in the extracts by different methods, but the composition of volatiles in the extracts were different. Alcohols and hydrocarbons were the major functional groups in SDE and SE extract whereas esters and hydrocarbons were the major functional groups in SPME extracts. SPME was the most suitable method for analysis of fresh volatiles from Fuji apples.
