    There are several methods for the determination of Ipecacuanha roots, such as the determination of total alkaloids as emetine, or separation into phenolic and nonphenolic bases and determination of each base as cephaeline or emetine, but neither of these can be termed a perfect one for separation of the componental alkaloids. Systematic separation of various alkaloids in the Ipecacuanha root was attempted through partition chromatography. Two chromatographic columns were connected end to end, using Celite as the retaining agent for the stationary phase of N sodium hydroxide and a buffer of pH 6.4 for each of the columns. The total alkaloids were charged on the upper column and the columns were developed with ether as the moving phase to fix the phenolic bases in the first alkaline column and separated from the non-phenolic bases. The columns were then eluted consecutively with chloroform and chloroform-ethanol mixture (5:1) to elute out cephaeline and psychotrine. The non-phenolic bases that transited to the second column were eluted consecutively with ether, chloroform, and chloroform-ethanol mixture (5:1) to separate emetine from other non-phenolic bases such as emetamine and O-methyl-psychotrine. The separated emetine, cephaeline, and psychotrine were determined by non-aqueous titration with a good result.

    The isolation of 10 sorts of alkaloid, shown in Table I, extracted from Engosan, Chinese plant are described. Two new phenolic bases isolated in protoberberine series alkaloid among them have been named Corydalmine (V) (m.p. 238-239°(vac), [α]D30+337.4 (CHCl3), C20H23O4N, colorless needles) and dehydrocorydalmine (VII) (Iodide, m.p. 228-230° (docomp) C20H20O4NI⋅2.5H2O, yellowish orange needles), respectively. It has been confirmed that O-CH3 derivative of (VII) corresponded palmatine and that the tetrahydro derivative to (V). The compound (V) provides one hydroxyl group and 3 methoxy groups which may attach at 2, 3, 9 and 10 position.
    From the nature of negative reaction to the Gibbs reagents, no hydroxyl group at 3 or 9 position of the tetrahydroberberine nuclei has been found to exist. Furthermore, an admixture of the samples and a comparison with IR spectrum showed that they were not coincidend with tetrahydrojatrorrhizine (II), tetrahydrocolumbamine (III) or palmatrubine (IV). This fact suggested the presence of hydroxy group at 10 and the OCH3 at 2, 3 and 9. (VII) is the dehydroform of (V).

    It has been found that higher alkyl sulfate (C 10-18) of several basic chemicals such as thiamine form complexes comparatively easily with cyclodextrin, especially α-dextrin in water or hydrated ethanol solution.
    The complexes contain about 10% of alkyl sulfate which was extracted by 90% ethanol at room temperature. A comparison of X-ray diffraction patterns by the powder method showed that these complexes have a resembling crystalline structure with the cyclodetrin complexes already known and it was concluded to be inclusion compounds having constant molar ratio.
    It was also observed that the thiamin dilauryl sulfate among α- and β-cyclodextrin complexes provided pretty higher stabilities against alkali under high temperature and high humidity.
    Water soluble chemicals which are usually difficultly included, will form inclusion compound when it will be transfered to alkyl sulfate.

    1-Phenyl-1, 2-bisbenzamido-1-propene (III) was obtained by treating 4(5)-methyl-5(4)-phenylimidazole (II) with benzoyl chloride, prepared by the reaction between 1-hydroxy-1-phenyl-2-propanone (I) and formamide. By the reduction of (III), followed by the hydrolysis, it gave erythro-1-phenyl-1, 2-propanediamine (V), which was also derived from the imidazol compound (VI), prepared by the reaction between (I) and urea. When methylbromide was reacted to N, N, N′, N′-tetramethyl compound of (V), N-methylephedrine methobromide were produced by the partial decomposition. The hydrolysis of (III) gave N-(α-acetylbenzyl) benzamide, from which were prepared erythro-1-amino-1-phenyl-2-propanols and threo-isomers, shown in Chart 2.

    The preparations of N-substituted 3-hydroxy-3-phenyl-4-amino-2-butanone (II) from 1-hydroxy-1-phenyl-2-propanone (I) by the Mannich reaction are described. The reduction of the above compound obtained gave 1-amino-2-phenyl-2, 3-butanediol derivative (III) and its diastereoisomer, and the Grignard reaction gave 1-amino-2-phenyl-3-alkyl (or aryl)-2, 3-butanediol derivative (V). The Mannich base of 1-phenyl-2-propanone was reduced to N-substituted 3-phenyl-4-amino-2-butanol.

    It is well known that the homogenizer is a very effective equipment for O/W emulsification. However, when the preliminary emulsion containing a large amount of oil as the internal phase was processed with the Hydropulse homogenizer at high pressure, it happened to decrease the emulsion viscosity and increase the specific resistance. The phenomenon was found to be a phase inversion with partial separation of oil phase and this occurred at a lower processing pressure when the oil phase volume was larger and the preliminary emulsion temperature was higher. Tolerable maximum processing pressure at which phase inversion did not occur was called “critical processing pressure.”
    The data of this study were subjected to statistical evaluation and indicated that the first- and second-order term of oil phase volume and the first-order term of preliminary emulsion temperature significantly affected “critical processing pressure.” Moreover, the observation equation was introduced by the method of least squares, as follows: P=6.53V2-1100V-17T+47350 where P is the critical processing pressure (psi), V is the oil phase volume (in %), and T is the preliminary emulsion temperature (°C). The possibility that the hydrodynamic cavitation might be a significant factor in phase inversion was discussed.

    Emulsion is broken in two passages, by drainage and coalescence. In order to estimate the coalescence of emulsion, the constant amount of oil-in-water sample emulsion on a flat glass plate was dried by maintaining at relative humidity of 11%, and the coalescence of oil particles was accelerated. The increase in size of oil particles with time was measured by the turbidimetric method.
    As shown in Figs. 1, 2, and 3, where extinction was plotted in logarithmic scale against drying time, it was observed that the most plots were linear and consisted of two fairly well-defined regions, one in which the change of extinction was very little with time, and the other in which the decrease of extinction was much more rapid. There was a marked correspondence between the sustaining time to coalescence determined by this method and the shelf stability found at room temperature for long period, except for a viscous sample.

    2-Chloro-3-R-quinoxaline (R=OCH3, OC2H5, OCH(CH3)2, OC4H9, OCH2CH(CH3)2, OCH(CH3)(C2H5)) is prepared by addition of sodium alkoxide to 2, 3-dichloroquinoxaline. Addition of hydrazine hydrate to it easily gives 2-hydrazino-3-R-quinoxaline. This hydrazino compound undergoes cyclization to 1-substituted 4-R-s-triazolo[4, 3-a]quinoxaline by reaction with ortho-ester and acetic anhydride. Although it undergoes cyclization to the triazole compound by reaction with formic acid, R is hydrolyzed when it is OCH(CH3)2 and OCH(CH3)(C2H5), and forms s-triazolo[4, 3-a]quinoxalin-4-ol. Heating of 1-methyl-4-methoxy-s-triazolo[4, 3-a]quinoxaline to above its melting point results in rearrangement of the methyl group in methoxyl to the nitrogen in 5-position to form 1, 5-dimethyl-s-triazolo[4, 3-a]quinoxalin-4(5H)-one.

    The extraction method with isopentyl alcohol was found to be very suitable for the micro quantitative determination of copper (ca. less than 1γ/cc.) and, 4, 4′-diphenyl-6, 6′-dimethyl-2, 2′-biquinoline (PMB), the most sensitive reagent among them, has been employed for the determination. UV spectrum of PMB, as well as UV and visible region spectra of cuprous chelate were measured and the colorimetric determination of trace of copper has been established by measuring at 554mμ. The molar ratio of copper to PMB was found to be 1:2 in isopentyl alcohol and it may be capable to determine quantitatively within 0.02γ to 0.8γ/cc., following the Beer's law. Various conditions of pH, temperature, as well as the copresent ions in this determination was examined and the quantitative determination of copper in animal organs was attempted.

    The reaction of phenols and phenylhydrazines in the presence of an oxidation agent and basification of the reaction mixture resulted in coloration of phenols to red to blue. In general, phenols possessing positive groups color easily but those having a negative group do not undergo coloration. Phenols with positive group in the para-position hardly undergo coloration.
    Phenol was reacted with 2, 4-dinitrophenylhydrazine, in the presence of Chloramine T, and separation of its reaction product was attempted. Extraction of the reaction mixture with chloroform and purification of its product by alumina chromatography afforded reddish brown needles, m.p. 186.0°, whose analytical values and absorption spectra in the ultraviolet, visible and infrared regions agreed with those of p-benzoquinone 2, 4-dinitrophenylhydrazone. The prodnct was identified with p-benzoquinone 2, 4-dinitrophenylhydrazone, synthesized from p-benzoquinone, by mixed fusion.

    48 varieties of 2-acyl(or aroyl)-5, 6, 7, 8-tetrahydro-1(or 3)-naphthol, aryl 1-(or 3-)hydroxy-5, 6, 7, 8-tetrahydro-2-naphthoate and 1-(or 3-)methoxy-2-aroyl-5, 6, 7, 8-tetrahydronaphthalen were synthesized. They provided two absorption maxima in the U V region. Except two cases, the maxima of 1-hydroxy-2-carbonyl compounds in shorter wave length region shifted 3-9mμ to longer wave length region from that of 3-hydroxy-2-carbonyl compounds. The absorption maxima of the former in longer wave length region shifted 4-9mμ to shorter wave length region from that of the latter.
    The shift in the shorter wave length region is explained by the stronger intermolecular chelate formation of 1-hydroxy-2-carbonyl compounds and the shift in the longer wave length region is supposed to be easier formation of para-quinoid form of 3-hydroxy-2-carbonyl compounds.
    Though 1-hydroxyketone compounds are very stable against sun light, o-hydroxy-carboxylic acid esters are generally unstable and o-methoxy ketones are also unstable.

    The fusion reaction between homoveratrylamine and diethyl 2-ethoxycarbonyl-3-methyl glutarate was investigated and two kinds of monoamide diester, two kinds of diamide and a triamide were obtained. One of the monoamides was hydrolyzed, decarboxylated and later cyclized to N-homoveratryl-3-methylglutarimide, which was identified by the admixture with the sample synthesized by the other route. Similary, the cyclization of diamide afforded imide derivative, partially cyclized to isoquinoline. The structure of the cyclized products from triamide is still examining.

    Antitussive activities, antispasmodic activities, as well as acute toxicities of oxeladin have been investigated. The antitussive activities of oxeladin citrate on guinea pig by the mechanical stimulation method was a little weaker than that of codeine phosphate, when injected intraperitoneally, and the activities of less soluble oxelaldin tannate, when administered per os, was as same as codeine, being converted to the free base, with longer duration. As to the antispasmodic activities by employing isolated tracheal chain preparation, it showed strong papaverine-like action and very weak atropine-like action, without having any antihistaminic activities. LD 50 by subcutaneous injectione of oxeladin citrate to mice was 244mg./kg. and that of oxelaldin tannate to mice per os was not less than 1500mg./kg.

    The component of essential oil from Artemisia annua L. was investigated and both hexanal and l-α-pinene were isolated as a low boiling point component. Benzylalcohol acetate, d-2-methyl butyrate, cuminal, caryophyllene oxide, and pentacosane were isolated as a high boiling point component. Besides that, aldehyde compound (semicarbazone, m.p. 200°, 2, 4-dinitrophenylhydrazone, m.p. 157-159°) of C10H16O, and ketonic derivative (2, 4-dinitrophenylhydrazone, m.p. 181-183°) of C15H24O have been isolated and also a presence of monoterpene alcohol derivative bp5 90-95°, as well as the sesquiterpene alcohol derivative of bp5 134-140°, have been suggested, though their identification have not yet been made.

    The relationship between the actions toward small intestine and the chemical structures of the various kinds of compounds, providing hydrocarbon, or alcoholic or phenolic hydroxyl group, which are the main component of plant essential oils, applicable to the therapeutic chemicals, has been studied.
    In this connection the action to small intestine has been examined by the Magnus method using extracted small intestine from mouse with the plant essential oils themselves in which the effective component are considered to exist.
    The monoterpenoids, namely α-pinene, limonene and dipentene, which belong to hydrocarbon group showed stronger contracted action and the substances of having alcoholic hydroxyl group such as linalool, citronellol, geraniol and menthol showed musclotropic antispasmodic action. This action was also found to be strengthened considerably with thymol, carvacrol and eugenol which have phenolic hydroxyl group. The contracted action was also observed with the orange oil, mandarine oil, turpentine oil and fennel oil but peppermint oil and clove oil showed musclotropic antispasmodic action. These actions are supposed to be represented by the main component of the oil, but the contracted action was also observed with mosla oil, Oyamajiso oil, and eucalyptus oil and it showed different reaction from that of the main component.

    The Friedel-Crafts reaction of 1, 6-dimethoxydibenzo-p-dioxin (II) with acetylchloride in carbon disulfide, in the presence of AlCl3 gave diacetyl derivative (III) in a better yield. Oxidation of (III) with potassium permanganate in a mixture of 2.5% KOH and pyridine afforded corresponding dicarboxylic acid (IV) in a better yield, which was esterified quantitatively to methyl 1, 6-dimethoxydibenzo-p-dioxin-4, 9-dicarboxylate (V) by diazomethane.
    In the Friedel-Crafts reaction, a small amount of colorless needle crystals, m.p. 228-230° was produced as a by-product, which might be either 1-acetoxy-4-acetyl-6-methoxydibenzo-p-dioxin or 1-acetoxy-2-acetyl-6-methoxydibenzo-p-dioxin (VII), suggested from various investigations. Therefore, it was found that the substitution at the nucleus in this reaction took place dominantly at para position of methoxyl group of (II).
