For storage periods of tubers in Chinese yam, the levels of GA/sub 44/ and GA/sub 20/ was constant, meanwhile both GA/sub 53/ and GA/sub l9/ level were always higher than that of GA/sub 44/ and GA/sub 20/ㆍ GA/sub 9/ content as precursor of GA₄ was not changed during storage. GA/sub 24/ content was low to below 0.2 ng for 90 days after storage, GA/sub 36/ content as precursor of GA₄ like GA/sub 9/ was about 6-8 fold higher than that of GA/sub 9/ during storage. GA contents of the two gibberellin biosynthetic pathways were gradually increased when storage periods were progressed. Bioactive GA₁ content as the GA members of an early C-13 hydroxylation was always constant, and its content was very low as below 0.1ng per dry weight, meanwhile, bioactive GA₄ content as the GA members of non C-13 hydroxylation was drastically increased, also, its content was highest at 90 days after storage, and then decreased at 120 days after storage. Consequently, we suggest that GA₄ may be involved in controlling tuber sprouting in Chinese yam.

본 연구는 한국산 마의 괴근 형태로 분류되는 장마와 단마를 개화기에 꽃의 방향 성분과 정유수율을 비교조사하여 향료로서의 기능성을 검토하기 위하여 실험을 수행하였던 바 얻어진 결과를 요약하면 아래와 같다. 1. 마꽃의 방향 성분은 총 26종이 확인되었으며 지방족 알콜류가 다량분포하여 향료 첨가물이나 향수의 기본재료로의 가능성이 있는 것으로 나타났다. 2. 단마는 장마보다 1,2-butyleneglycol은 11배, phenylalcohol은 12배, caproic acid는 28배, cis-3-methylsalicylate는 8배, cinnamic alcohol은 25배, α -hexyl cinnamic acid는 13배, laulic acid는 6배 높은 경향을 보였다. 3. 마꽃 방향 성분의 수율은 0.7%로서 그 이용 가능성이 크며 단마가 0.983%, 장마가 0.417%로 단마가 약 2.4배 수율이 높았다. 4. 마꽃의 방향 성분 조성과 정유성분 수율을 감안할 때 마의 부산물인 마꽃을 향료로서의 이용 가능성이 있다고 판단되었다. The study was carried out to identify compositions and recovery yield of aromatic compounds of flower in Chinese yam (Dioscorea batatas Decne). Total 26 volatile aromatic compounds were identified and peak area percentage of aliphatic alcohol in Dan-ma was higher than in Jang-ma. Major volatile aromatic compounds analyzed by GC/MS were 1,2-butyleneglycol, phenylalcohol, caproic acid, cinnamic alcohol, and palmitic acid. Recovery yield of essential oils of Dan-ma was higher than in Jang-ma as 0.983%. As a result, it was concluded that Chinese yam was worthy of cultivating as perfume and medicinal crops.

This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were $\alpha$-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.
