Four steroids have been isolated from the subterranean parts of Smilax nipponica Miquel (Liliaceae). The structures of these compounds were characterized on the basis of chemical and speectral data. They were $\beta$-sitosterol, $\beta$-sitosterol-3-O-$\beta$-D-glucopyranoside, neotigogenin-3-O-$\beta$-D-glucopyranoside and a new steroidal saponin designated as smilanippin A which was elucidated as neotigogenin-3-O-$\beta$-D-fucopyranosyl(1$\rightarrow$6)-$\beta$-D-glucopyranos ide.

Extraction-spectrophotometric determination of mercury(Ⅱ) was studied by associated complex formation using antipyrine, antipyretics and eosin, halogenated xanthenes. K₂SO₄was added for the promotion of complex formation and it's optimal concentration was 0.3M. Optiaml conditions for the quantitative analysis of trace of mercury(Ⅱ) were investigated. Molar ratio of Hg(Ⅱ)-antipyrine-eosin complex was presumed as 1:4:2. Linear calibration curve was obtained in the range of 6~28㎍/㎖ at 485nm. Mercury(Ⅱ) determination of this method was interfered in the presence of metals such as ??, ??,, ??, ?? and ??, halides an dthiocyanate, but the interferences of metals except ?? were masked with 0.01M-sod. tartrate.

I collected nine lind of plants around us in order to analyze catechol type tannin which is contained in plants. The analysis was made by Lowenthal's volumetric analysis method and paper chromatography method. At this experiment, the rate of developing solvent of paper chromatography was n-butanol: acetic acid: water=5:2:6(vol.%), and developing, Quercus aliena Blume, Quercus aliena Blume var. acute-serrata Maximowicz ex Wenzig and Quercus aliena Blume var. pellucida Blume, much tannin.

Schrophularia burgeriana Miquel (Scrophulariaceae) is a peennial herb growing in all parts of Korea. It has been used as Korean folk medicine in treation guttural diseases acting as an antiphlogistics, antipyetics and analgesicss. In this paper, the structural elucidation of chemical componets was studied. From the roots of this plant, a phthalate and an iridoid glycoside were isolated and identified as bis (2-ethy1 hexy1) phthalate was orginaged from solvents. Aucubin was first isolated from Scrophularia buergeriana Miquel.

Carboxylic acid is converted to acid chloride by thionyl chloride. Acid chloride reacts with 2.4-dinitrophenylhydrazine (2.4-D.N.P.H) to form the corresponding hydrazide. this hydrazide in aqueous basic solution leads to color-formation which can be utilized for colorimetric analysis. Since acid chloride is readily hydrolyzed to the parent carboxylic acid in the water, the coupling reaction of acid chloride with 2.4-D.N.P.H is carried out in actonitrile solution. the structures of N-acetyl-, N-benzoyl N'-(2.4-dinitro) phenyl hydrazine formed from the reaction of carboxylic acid and 2.4-D.N.P.H. are investigated by NMR and IR-spectrum.
