Drs. T. Takada, K. Hieda, and R. Hanai, all from Rikkyo University, carried out a field work at East Tibet in August, 1999. Continuously, Drs. C. Kuroda and J. Suhara botanized at Yunnan areas in August, 2000 and 2001. A survey of floweing plants, measurment of UV intensity, collection of barley for analysis of trace rare-earth elements, adaptation of bryophytes to environmental chenges, and the chemical components of various Ligularia spceies were studied.It was found from these field works to draw the following facts :1. Elements determined were Ti, V, Zn, W, Au, Pb, and rare earth elements in barley samples by ICP-MS method. The results showed increasing concentration of trace metal elements in stems and whisker than seeds. The results are also presented that the Tibetan barley samples contained much higher levels of rare earth metals (the highest conc. : Ce 1.05 μg/g, the lowest conc. : Dy 0.05 μg/g in seeds) than that of Japan.2. A plant observed on most of the route was Delphiniu … More m, of which several species were found. Species with smaller plant sizes but with larger flowers were found in regions with larger elevation and drier and chiller climate, as the trip proceeded, westward.3. Morphologies typical of cold regions were observed. For instance, the "green-house" morphology was observed for Saussarea and Ajuga species. Many species with the "cushion" morphology were also observed.4. A new allele, designated as "Y-type", was identified in north Yunnan (near Kunming), on the other hand, samples in south Yunnan had the S-type allele. The results seem to indicate that C. japonicum in Japan mostly originated in south Yunnan. The plant in north Yunnan (Lijian, Dali, Kunming, Zhaotong, and Daguan) was identified that the rbcL allele of all the samples was the Y-type.5. It was found that the main component of L. lankongensis and L. alatipes are eremophilan-7(11)-en-8-one(compound 1) and bakkenolide A(compound 3), respectively. While benzofuran derivative (compound 4) was isolated from L. longihastata as the major component.6. It was found that the plant cultured cells of Caragana chamlagu are more effective as biocatalyzer for allylic oxidation of terpenoids. Less

T医生高田角Hieda和R. 1999年8月，来自立教大学的哈乃在西藏东部进行了一次实地考察。一直以来，C博士黑田和苏原俊雄于2000年8月和2001年8月在云南地区进行了植物学研究。通过对开花植物的调查、紫外线强度的测量、采集大麦进行微量稀土元素分析、苔藓植物对环境变化的适应性以及不同Ligularia种的化学成分进行了研究，发现以下事实：1.采用电感耦合等离子体质谱法测定了大麦中的Ti、V、Zn、W、Au、Pb和稀土元素。结果表明，茎和须中的微量金属元素含量高于种子。西藏大麦中稀土元素含量最高为Ce 1.05 μg/g，最低为Dy 0.05 μ g/g，远高于日本大麦.在大部分路线上观察到的植物是翠雀 ...更多信息 随着行程的向西推进，在海拔较高、气候干燥寒冷的地区发现了植株较小但花朵较大的物种.观察到寒冷地区的典型形态。例如，“温室”形态观察到的雪莲属和筋骨草物种。许多种具有“垫状”形态.在云南北部（昆明附近）发现了一个新的等位基因，命名为“Y型”，而在云南南部发现了一个新的等位基因，命名为S型。结果表明，C.日本的日本血吸虫主要起源于云南南部。滇北地区（丽江、大理、昆明、昭通、大关）的植物样品rbcL等位基因均为Y型。结果表明，L. lankongensis和L. alatipes分别是eremophilan-7（11）-en-8-one（化合物1）和bakkenophilan A（化合物3）。而苯并呋喃衍生物（化合物4）是从L.长戟叶为主要成分。结果表明，锦鸡儿细胞是一种有效的萜类化合物烯丙位氧化的生物催化剂。少
