Histotaxonomical Study of Medicinal Ranunculaceae Plants

1.铁线莲属植物的研究结果：毛果铁线莲叶的解剖学研究。来自大陆的中国等人被抬了出来。结果表明，将前者视为后者的变种是不正确的。此外，两种植物的地上部分均被证实为产于四川的中药材“味灵仙”的成分。对乌头属植物的研究结果：对尼泊尔乌头属乌头的块根进行了形态和解剖学研究。结果表明，乌头属植物起源于尼泊尔草药市场，而不是飞燕草属植物，而且尼泊尔产的一些乌头属植物来源于乌头属植物的块茎。对中国黄连属植物和日本黄连属植物的8种3变种进行了组织分类研究。对黄连叶片栅栏薄壁细胞的大小、根茎中厚壁组织细胞的出现频率等诊断特征进行了观察，并根据这一结果明确了不同市场黄连药材的植物来源。编制了富山医科大学药物馆标本馆藏的尼泊尔毛茅科植物标本名录。

1 . The results on Clematis plants: The anatomical study on the leaves of C.leiocarpa Oliv.and C.uncinata Champ. from China mainland were carried out. The result shows that it is not correct to regard the former species as a variety of the latter one. Moreover, the aerial parts of both species were proved as the ingredients of the Chinese crude drug "Wei-ling-xian" from Sichuan Province.2. The results on Aconitum plants: The tuberous roots of a Nepalese aconite, Aconitum orochryseum Stapf was studied morphologically and anatomically. As a results Aconitum was clarified as the botanical origin of Nirbisi circulated in Nepalese herb markets, not Delphinium species, and further more, some of Nirbisi produced in Nepal were derived from the tuberous roots of A.orochryseum.3. The results, on Coptis plants: 8 species and 3 varieties of Chinese and Japanese Coptis plants were studied histotaxonomically. The diagnostic characters were observed on the size of palisade parenchyma cells in the leaves, the frequency of sclerenchyma cells in the rhizome, etc. According to this result, the botanical origin of the crude drugs derived from Coptis plants in various markets were clarified.4. A list of Ranunculaceae specimens from Nepal in the herbarium of The Museum of Materia Medica, Toyama Medical and Pharmaceutical University, were made.
