 note = {Three kinds of plants which grow in the lava zone of Hakamagoshi, Sakurajima, Japan, were compared with a view to studying the chemical ingredients of their bodies.
1. Ingredients were extracted (1) with hot water and (2) with hot methanol from the plants in solution form.
2. The solution extracted through the first process (hot water) was first precipitated with saturated lead acetate solution, then the filtrate was subjected to saturated vinegar of lead solution, and lastly to saturated bariumhydroxide solution. These precipitates were named ppt. A, ppt. B, and ppt. C in the order of process. Aqueous solution of some glucosides was individually separated from each precipitate by dropping 2N H_2SO_4, and then the solution was condensed under reduced pressure under 50°C. into coencentrated extracion.
3. The solution extracted through the second process (hot methanol) was condensed into almost dried residue, from which some glucosides were extracted in the form of aqueous solution through the process of shaking it together with water and chloroform.
4. Each aqueous solution of four glucosides (a, b, c and d) was hydrolized with alcoholic solution of 3N HCl for six hours into aglycones which were agly. A, agly. B, agly. C and agly. D respectively.
5. Each fraction of aglycones extracted with chloroform was examined by using ten kinds of spot color reactions that are usually applied to several aglycones already known.
6. Comparison of the results of color reactions between the four aglycones under study and the known ones indicated the existence of common substances of steroid or its derivatives in the partition from the agly. A and agly. C in all cases of the plants examined.
7. Further research with a thin layer chromatography estimated the Rf values of the common substances at around 0.95. It might be inferred from the results mentioned above that there is some correlation between the growth of the three plants in the lava zone and the common glucosides contained in their bodies., 1. 桜島袴腰の大正溶岩に自生するイタドリ・タマシダ・コケの3種の植物体を材料とし,その水浸出液から酢酸鉛,塩基性酢酸鉛,水酸化バリウムの飽和水溶液で分劃沈殿させ,これを2N H_2SO_4で遊離濃縮によって得た配糖体エキスと,同じ材料をメタノールで抽出し,濃縮後クロロホルムで処理して得た配糖体エキスとが準備された。2. それらの配糖体エキスをアルコール性3N HClで6時間加水分解し,クロロホルムで抽出された成分をAglyconeとして,10種の点滴呈色試験に付した。3. 10種の呈色試験結果と既知のAglycone呈色反応とを対比し,大正溶岩に自生する3種の植物体成分に共通なものとしてSteroid配糖体の存在を予想した。4. 加水分解で得られた試料を薄層クロマトグラフィによって展開し,Rf値0.95付近に共通成分が認められることを明らかにした。},
