项目摘要

Botanical significance of plants of Yunnan, China has been pointed out in view of bioloigical relationship between Himalayan and Japanese plants. In this research projcet, chemotaxonomical and species-biological comparison of plants of Yunnan with those of Japan and the related area has been conducted under the close co-operation with Kunming Institute of Botany, Academia Sinica. The following results were obtained;1. Panax species, Araliaceae: The similarity of the saponin-compostion of Panax species in Yunnan to those of Eastern Himalaya and South-Kyushu was disclosed. The anomalous saponin-compostions were observed for the plants growing in the western and southern limits of the distributuion. 2. Bupleurum species, Umbelliferae: Comparison of the physiologically active saponins of the species of Yunnan with those of northern China, Korea and Japan was conducted, showing the good quality of plants grwoing in Yunnan as the medicinal resources. 3. Cucurbitaceous plants: Isolation and structural determination of sweet cucurbitane-glycosides from plants of Yunnan were achieved. It was also revealed that glycoside-composition of Hemsleya spesies has the significant relationship with the taxonomy. 4. Camellia species, Camelliaceae: Chromosome number of a number of this species was investigated. The morphogical comparison of chromosomes of this species was also estalbished. 5. Asarum species, Aristolochiaceae: Chemical constituents of essential oils of this species growing in Yunnan and other districts of China were compared with those of Japan by GC-MS, affording the important evidence for the origin of Japanese species.

云南植物的植物学意义，中国从喜马拉雅植物与日本植物的生物学关系出发，指出云南植物的植物学意义。本研究与中科院昆明植物研究所密切合作，对云南与日本及相关地区的植物进行了化学分类和种生物学比较。主要研究结果如下：1.五加科人参属植物：云南人参属植物的皂苷成分与东喜马拉雅和南九州的人参皂苷成分具有相似性。在分布的西界和南界的植物中，观察到了异常的皂素组成。2.柴胡属植物、伞形科植物：对云南柴胡属植物与中国北部、朝鲜、日本等地的柴胡属植物的生理活性皂苷进行了比较，表明云南柴胡属植物作为药用资源具有较好的品质。3.葫芦科植物：从云南产植物中分离得到甜瓜糖苷类化合物，并对其结构进行了鉴定。研究还表明，该属植物的糖苷组成与其分类学关系密切。4.山茶属，山茶科：对山茶属植物的染色体数目进行了调查。并对该种的染色体进行了形态比较。5.细辛属、马兜铃科：采用GC-MS法对产于云南等地的马兜铃科植物与日本产细辛挥发油的化学成分进行了比较，为日本细辛属植物的起源提供了重要依据。
