ジャーナル フリー1) α-Dichloroacetamido (or acetamido)-β-hydroxy-p-nitropropiophenone is esterified by acetic anhydride and conc. sulfuric acid to form α-dichloroacetamido (or acetamido)-β-acetoxy-p-nitropropiophenone, but the reaction, if carried out in acetic anhydride and pyridine, results in dehydration to yield α-dichloroacetamido (or acetamido)-α-methylene-p-nitroacetophenone.
2) The Meerwein-Pondorf reduction of α-dichloroacetamido-α-methylene- and α-acetamido-α-methylene-p-nitroacetophenone results in dehydration and migration of the double bond to yield 2-dichloromethyl-4-methyl- and 2, 4-dimethyl-5-p-nitrophenyloxazole, respectively.

ジャーナル フリーA mixture of fatty acids (100g.) was obtained from the fruits (1150g.) of Anthriscus sylvestris Hoffm., this mixture being separated into 70g. of solid acids and 18g. of liquid acids. The majority of the solid fatty acids was found to be petroselic acid (I), m. p. 32-33°, the remainder being a small amount of petroselidic acid (II), m. p. 53°. The liquid fatty acids, on oxidation by Hazura's method, yielded a small amount of 6, 7-dihydroxystearic acid, m. p. 122°, and a comparatively large amount of 9, 10, 12, 13-tetrahydroxystearic acid (α-sativlc acid), m. p. 162°, which showed that the majority of the liquid acid is linoleic acid. It is doubtful, however, if petroselidic acid had been contained, per se, in the fruit or whether a portion of petroselic acid had undergone elaidination. This must be confirmed by actual experimentation.抄録全体を表示PDF形式でダウンロード (657K) -

ジャーナル フリーA mixture of fatty acids (154g.) was obtained from the fruits (1227g.) of Conium maculatum L. These acids were converted to methyl esters and fractionally distilled into Fraction A, b.p.1 130-148°, and Fraction B, b.p.1 149-152°. Each fraction was divided into solid (67%) and liquid (33%) acids. Fraction A yielded, as a solid acid, petroselic acid, m.p. 32-35°. Fraction B yielded, as a solid, an acid of m.p. 30-31°, corresponding to formula C18H34O2 (_??_=1), elaidination of which gave petroselidic acid, m.p. 53°. From the melting point, the primary acid is assumed to be a mixture, chiefly of petroselic acid containing a small amount of petroselidic acid. The liquid acid yielded, by the Hazura oxidation, 9, 10-dihydroxystearic acid in a small amount, and a comparatively large amount of α-sativic acid. These results show that the said fruit oil contains as fatty acids, a large amount of petroselic acid, with a small amount of oleic and linoleic acids, and a very minute amount of petroselidic acid.抄録全体を表示PDF形式でダウンロード (616K) -

ジャーナル フリーBy methylation of (2, 3-cis- and -trans-dihydroxycyclohexyl) -acetic acid lactone (V and VI) with methyl iodide in the presence of silver oxide yielded (cis- and trans-2-hydroxy-3-methoxycyclohexyl)-acetic acid lactone (VII and VIII), a liquid substance which failed to give the coloration shown by natural castelamarin, making it doubtful the Bosman's theory that castelamarin is a (2-hydroxy-3-methoxycyclohexyl)-acetic acid lactone. The application of methyl iodide and silver oxide to (2, 3-cis-and-trans-dihydroxycyclohexyl)-malonic acid lactone (XI and XII) results in the methylation of the hydrogen at C7 instead of the hydroxyl at C3. An isomeric racemate of (cis- and -trans-2-hydroxy-3-methoxycyclohexyl)-methylmalonic acid lactone (XVII and XVIII) due to the asymmetric carbon at C11 is present.抄録全体を表示PDF形式でダウンロード (733K) -

ジャーナル フリーIn continuation of the previous work [This Journal, 72, 67, 69 (1952)], components of Fraxinus commemoralis Koidz., was studied and syringin and mannitol were. obtained from the plants growing in Yamaguchi Pref., and syringin from those growing in Gumma Pref. This plant belongs to Sect. Fraxinaster, and aqueous extract of the bark fails to show any fluorescence. Whereas the plants of Sect. Ornus invariably yielded aesculin and aesculetin [This Journal: 58, 636 (1938); 60, 508 (1940); et seq.], and the aqueous solution of their bark showed strong fluorescence, those of Sect. Fraxinaster fails to give fluorescence. It may be assumed, from these results, that the presence of fluorescence in the aqueous solution of its bark classifies the plant as belonging to Sect Ornus, and its absence, as belonging to Sect. Fraxinaster.抄録全体を表示PDF形式でダウンロード (749K) -

ジャーナル フリーBy the fundamental experiments carried out with electric heating apparatus in micro-Dumas method, following observations were made. (1) The reversible reaction 2CO2⇔2CO+O2 can be made to proceed completely to the left by passing the conbustion air through a fixed burner of oxidized copper layer (over 4cm.) hea ted to 450-600°, at a rate of 10 bubbles per second. (2) Heating the movable electric burner to 850° results, in the presence of oxidized copper, in rapid dissociation of CO2 to CO and O2, and the nitrogen in nitrogenous compounds is quantitatively reduced or oxidized to N2, thereby making it possible to carry out the analysis without the use of reduced copper. However, compounds containing halogen must give definite analytical values only after the use of reduced copper. (3) As long as the temperature of the fixed burner is kept at that point mentioned above, the position of the reduced copper layer may be in the center of the fixed burner or the end of the tube.
From experimental results, calculation of corrected value for N2 may be made from the following:
Corrected value of N2=(Found value of N2)-(1% of Found value of N2)-0.01cc.抄録全体を表示PDF形式でダウンロード (806K) -

Especially strong activity was shown by phenanthrenequinone which succeeded in preventing the growth of molds for 42.5 days at 0.001% concentration, for 51.5 days at 0.003%, and for 77 days at 0.005%. Since the control prevented growth of molds for 77 days at 0.01% concentration, the activity of phenanthrenequinone must be classed as very strong. Other compounds were found to be all ineffectual.抄録全体を表示PDF形式でダウンロード (436K) -

ジャーナル フリーBy the employment of the present method, an acid for the saccharification of polysaccharides could be chosen without any consideration for the solubility of its salt. Peanut shells, which give a by-product of furfural with the formation of usual monosaccharide, was chosen as the polysaccharide material, and hydrolytic capacity of HCl, HClO4, H2SO4, HNO3 and H2C2O4 was compared, as well as electrolytic deacidification of their saccharifying solutions was attempted. As a result, it was found that acids such as HCl, HClO4, and HNO3, for which no neutralization agents could be found in industrial application, could be used both for saccharification and electrolytic neutralization. However, HNO3 and H2C2O4 undergo electrolytic reduction during electrolytic neutralization that disappearance of specific acid residue becomes rapid. This was the first instance of HClO4 being used for saccharification but it was found to have no oxidative or reductive action, saccharifying power being as excellent as HCl, and can be completely deacidified by electrolysis, similar to H2SO4, and quantitatively recovered. In this way, HClO4 has been discovered as an acid for saccharification by this method, although unusable by the existing method.抄録全体を表示PDF形式でダウンロード (780K) -

ジャーナル フリーExperiments were carried out to confirm the theory that some heavy metal ions promote saccharification. Saccharification of peanut shells with 0.8 N HClO4 solution was carried out with the addition of one of Fe+++, Al+++, Cu++, Pb++ and Hg++, and the formation of monosaccharide and furfural was observed. Elimination of heavy metal ions from saccharifying solutions by electrolysis was also examined. It was found, from these experimental results, that the presence of heavy metal ions during saccharification had neither favorable nor adverse effect, although it was also found that these metallic ions were all quantitatively removed by electrolytic deacidification of acid saccharifying solutions.抄録全体を表示PDF形式でダウンロード (505K) -

ジャーナル フリーThe reaction mechanism whereby thiochrome (II) is formed by the application of cyanobromide to 3-(2′-methyl-4′-aminopyrimidyl-5′)-methyl-4-methyl-5-β-hydroxyethyl-thiazol-2-thione (I) has been confirmed as follows: the cyclization to (II) occurs under liberation of hydrogen thiocyanide between the amino and the thiocyano groups in the initially formed thiocyano compound (VI), and not by the secondary cyclization of a thiazolone compound (III) formed from the initially formed thiocyano compound (VI). It was also found that thiochrome (II) is formed by the cyclization under liberation of mercaptane, under the same mechanism as above, upon the application of dimethyl sulfate, ethyl iodide, benzyl chloride or monochloroacetic acid to (I).抄録全体を表示PDF形式でダウンロード (743K) -

ジャーナル フリーBy the bromination of an oily mixture (III) of arctigenin (I) and its isomer, l-α-3, 4-dimethoxybenzyl-β-3′-methoxy-4′-hydroxybenzylbutyrolactone (II), bromoarctigenin (V), C21H21O6Br3, was obtained as crystals of m. p. 194-195°. Debromination of (V) with copper-coated zinc yielded arctigenin, m. p. 100-102°, C21H24O6, thus completing synthesis of arctigenin. Oxidation of the methyl ether (VI) of (V) with potassium permanganate yields 6-bromoveratric acid, m. p. 182-183°, and 5, 6-dibromoveratric acid, while the same oxidation of (V) yields 6-bromoveratric acid. This has confirmed that, of the three bromine atoms, one has entered the 6-position in the β-benzene nucleus of butyrolactone, while the other two has entered the 5- and 6-position in the α-benzene nucleus.抄録全体を表示PDF形式でダウンロード (539K) -

ジャーナル フリーSeveral kinds of hydroxy-4-methylcoumarins were prepared and their antioxidative action against vitamin A in liver oil was examined. It was found that dihydroxydi-hydro derivatives possessed the most effective action, followed by the dihydroxy derivatives, monohydroxy derivatives being the most ineffective. An alcoholic extract of germs, insoluble in ether, possessed acertain a mount of cooperative action in increasing this antioxidative action. This is assumed to be the same kind of relationship that is shown by the ether extract and the ether-insoluble alcoholic extract of the germs towards antioxidative action against vitamin A oil.抄録全体を表示PDF形式でダウンロード (745K) -

ジャーナル フリーAntimicrobial action of chenopodium oil and its various fractions was examined. In tests with bacteria, it was found to be slightly effective against Mycobacterium, but possessed no perceptible action at 1:1000 dilutions. It was, however, found fairly effective against dermatopathogenic fungi, especially the ascaridol fraction which prevented growth of the mold at 1:6, 400 dilution, the action being unchanged upon the addition of serum or by continuous cultivation, without too irritating an action against human skin. This has, in a way, confirmed the general use of chenopodium oil as a home remedy for athlete's foot.抄録全体を表示PDF形式でダウンロード (822K) -

ジャーナル フリーThe capon's comb test as a suitable means of biological assay was reëxamined and the five values, (L), (L+H), (L×H), “B-area” and the “total area”, of capon's comb were criticized from the viewpoints of statistics. Analysis were carried out as follows:
1) Experimental design of 4×4 Latin-square and its analysis of variance (Tables I, II and III).
2) Test of the significances of the linear, quadratic and cubic relationship between log doses and the responses (Table IV).
3) Tests of the significances of correlation coefficients (Table V).
4) Factorial analysis of test assay for testosterone with two doses of standard (D2, D4) and two doses of unknown (D1, D3), based on the experimental results. Comparison of the potency ratio to the dose ratio (√2) (Table VI).
After these analyses were carried out for each value (Table VII), “B-area” (Fig. 1 and (1), (2)) was certified by the present experiment to be the most suitable value for this androgen assay.抄録全体を表示PDF形式でダウンロード (906K) -

ジャーナル フリーQuercetin was obtained, and confirmed as its methyl and acetyl derivatives, from the flowers of Astilbe Thunbergii Miquel, collected during its flowering time on Mount Hiei, near Kyoto. A substance of m.p. 170-180°, giving positive Mg-HCl reaction, was also obtained but in a very minute amount. Astilbin and bergenin were obtained from the rhizome. Hydrolysis of astilbin gave rhamnose and distylin (3, 5, 6, 3′, 4′-pentahy-droxyflavanone). Methyl and acetyl derivatives of distylin were also obtained, as well as quercetin by its oxidation with 10% H2SO4. Bergenin was also confirmed as its acetyl and methyl derivatives. The fact that quercetin from the flowers and astilbin from rhizome were obtained from Astilbe Thunbergii is very interesting from phytophysiology and from phytotaxonomy together with the fact that whereas distylin has been individually found in Distylium racemosum S. et Z., and bergenin from Corylopsis spicata S. et Z., in Hamamelidaceae family, both have been found together in Astilbe genus of Saxifragaceae family.抄録全体を表示PDF形式でダウンロード (648K) -

ジャーナル フリー1) Transmission maximum of four kinds of filters was determined by the Beckman spectrophotometer for use in the colorimetric determination of the reddish purple color that appears upon the addition of 1% NaOH to the acetone solution of santonin-2, 4-dinitrophenylhydrazone. They have a transmission maximum at 500 mμ, but some of the filter were transparent above 650 mμ. The inclination and linearity of concentration-absorption curves decrease when, these filters are used. Two kinds of filters were prepared for the present experiments which gave more pronounced inclination and linearity to the curves but which were opaque above 650 mμ.
2) Filters must be kept in a dark place to avoid discoloration, and their properties must be checked from time to time.
3) By selenium-cell filter photometer, light absorptions (ε) were measured with the prepared filter in different concentrations (γ). The experimental equation was calculated from these data as follows: γ=1445ε+14.12
4) The standard deviation, δ, is 0.021, and the concentration limit, which corresponds to 2δ limit, is ±42.4γ.抄録全体を表示PDF形式でダウンロード (703K) -

ジャーナル フリーN1-p-Aminosalicylsulfanilamide (V), m.p. 119° (decomp.), was prepared by the following two routes:
i) Fusion of phenyl p-nitrosalicylate (I), sulfanilamide (II) and anhydrous potassium carbonate to yield N1-p-nitrosalicylsulfanilamide (III), m.p. 212° (decomp.), giving positive FeCl3 and diazo reactions, which easily was reduced to (V).
ii) Reaction of N4-acetyl compound (VI) of (II) and (I), under the same conditions as for (i) yields N1-p-nitrosalicyl-N4-acetylsulfanylamide (VII), m.p. 243° (decomp.), giving positive FeCl3 reaction and negative diazo reaction. Reduction of (VII) gives N1-p-aminosalicyl-N4-acetylsulfanilamide (VIII), m.p. 218-219° (decomp.), which is saponified to (V).
Saponification of (VII) yielded (III), whose acetylation provided (VII). From all these experimental results, it can be seen that the salicyl group in (III), (VII), (VIII), and (V) is attached to the N1 of (II).
In a similar manner, reaction of p-phenolsulfonamide (IX) with (I), in the presence of potassium carbonate, yieldedr N-(p-nitrosalicyl)-p-phenolsulfonamide (X), m.p. 205° (decomp.), whose reduction gave N-(p-aminosalicyl) compound (XI), m.p. 132-133° (decomp.).抄録全体を表示PDF形式でダウンロード (687K) -
