Authors could make clear that the total unsaturation of α, β-unsaturated organic acids (crotonic acid, acrylic acid, methacrylic acid and maleic acid) can be estimated quickly by the method using aqueous solution of bromine chloride prepared by acidifying the aqueous solution of potassium bromate and potassium bromide with hydrochloric acid.The iodine value of fatty materials containing isolated double bonds (oleic acid, methyl erucinate, olive oil, rape seed oil and sesame oil), and water insoluble acid samples such as cinnamic acid containing α, β-ethylene linkage were measured by the method using the solution of bromine chroride in glacial acetic acid. The results obtained in the analysis by the method were essentially similar to that of the Wijs method, except the results in the case of cinnamic acid. There is a remarkable agreement between the estimated iodine value of cinnamic acid and its theoretical value.

The structure of commercial transparent and translucent soaps have been investigated by means of X-ray diffraction, with the following results. 1) The structure of commercial transparent soap is not completely amorphous, but is believed to consist essentially of rather finer crystalline structure than ordinary opaque soaps.

Crude high density lipoprotein of egg yolk was fractionated by rate zonal ultracentrifugation. Rate zonal ultracentrifugation was carried out with zonal rotor RPZ-43T (660ml) in density gradient d. 1.00-1.40 by sodium bromide at 40000rpm.By the ultracentrifugation for four hours, the separation of high density lipoprotein (HDL) from low density lipoprotein (LDL) was observed, but HDL was completely purified only by the second ultracentrifiugation for twenty four hours after the first procedure.The purified HDL shows only one peak in the schlieren pattern of the analytical ultracentrifugation.

Lipids extracted from three pine seeds, Pinus koraiensis, Pinus armandi and Pinus cembra, were studied for general properties, fatty acid, sterol, phospholipids, and tocopherol content and autoxidation by the AOM test.All the lipids contained 14.718.6 % of Δ cis-5, cis-9, cis-12-octadecatrienoic acid (Δ 5, 9, 12-18 : 3 and designated here tentatively as pinolenic acid). The content of this acid in polar lipids was considerably less than in neutral lipids. The content of pinolenic acid in 2-monoacylglycerol was very low (1.22.6 %) and was thus considered distributed mainly at the 1, 3-position.Sterol composition consisted of three sterols, sitosterol, Δ 5-avenasterol and campesterol. Total sterol content of lipid extracted from P. armandi seeds was higher than that in the other two species.Phosphatidylcholine (PC), phosphatidyl ethanolamine (PE) and phosphatidylinositol (PI) were present as the major phospholipids.Total tocopherol content in pine seed lipids was less than in vegetable oils having high iodine value such as soybean oil and safflower oil. Oxidative stability by the AOM test was essentially the same as that of the above vegetable oils.

The degree of lytic action due to interactions between nonionic surfactants and liposomes was determined in terms of affinity for lipid membranes. The solubilization potential of some surfactants toward liposome membranes was estimated based on physicochemical measurements such as fluorometry to detect the release of fluorescent markers (calcein) from liposomes, turbidimetry in suspensions and surface tensiometry. The lytic action of the alkyl poly (oxyethylene) ether (POE) toward lipid membranes was greatest when the alkyl and ethylene oxide chain lengths were 12 and 8, respectively. The lytic action of nonionic surfactants with various hydrophobic portions (hydrogenated caster oil POE ethers, cholesteryl POE ethers, nonylphenyl POE ethers and POE stearate) was found to depend on structure. Maximum activity in each homologous series was 1.2 I.O.B. (Inorganic Organic Balance).The critical micelle concentrations (cmc) of dodecyl POE (5) and POE (10) ether in the absence and presence of liposomes were determined using a surface tension meter. Addition of liposomes caused cmc of the surfactants to increase. Dodecyl POE (5) ether causes marker release at lower concentration than cmc without change in turbidity. Dodecyl POE (5) ether concentration increase further, marker release from liposomes greatly increase minor change in turbidity. For dodecyl POE (10) ether, marker release started from cmc with decrease in turbidity. The lytic action of nonionic surfactants on liposomes would thus appear related to their capacity formixed micelle formation with phospholipids.

The existing test methods for measuring foaming and antifoaming properties of liquids are reviewed. The foaminess of liquids strongly depends on the test method. A number of methods cover most aspects of foam formation and stabilization. According to the principal of the foam generation, the foaming methods have been classified into two groups ; static and dynamic. The foam stability are expressed in terms of defined parameter such as the lifetime of bubbles, bubble size distribution and the gradual transformation of foam film caused by drainage.

オレイン酸メチルをモデルとしてジヒドロキシル化反応を新しい視点から研究した。試料を経時的に反応系から抜き取り, メタノール/硫酸で処理して残留するエポキシ中間体とアセチル化されたヒドロキシエステル類をそれぞれヒドロキシ-メトキシ及びジヒドロキシステアラートに変換した。キャピラリー GC-MS により各成分を同定し, さらに<SUP>13</SUP>C-NMR 及び<SUP>13</SUP>C-<SUP>1</SUP>H NMR により確認した。アンバーライトIR-120を触媒としたとき, ジヒドロキシステアラートの収率は 71.2% (オレイン酸メチルの変換率は87.7%) で, それには 50 minの反応時間で充分であった。
