Characteristics of introduction of fatty acids into Gajutsu (Curcuma zedoaria Roscoe) and Teppo-yuri (Lilium longiflorum Thunb.) starches

Abstract: Starch granules, normally, contain naturally occurring lipids which are firmly embraced in starch granules and hardly extractable with Et2O. In this paper, the characteristics of introduction of free fatty acids (FFAs) into Gajutsu (Curcuma zedoaria), Teppǒ-yuri (Lilium longiflorum) and potato starches, being very low in the above “embraced lipids” contents (9.2-25.6 mg%), were investigated. It was found that the saturated FFAs were more abundantly introduced into them (41.2-174.7 mg%) than the unsaturated ones (15.9-46.5 mg%), and the respective starches differed from one another in capacity of introducing each FFA. There was also found some characteristic changes in pasting feature after introduction of FFAs depending upon the respective starches. Furthermore, their Nageli-amylodextrins were prepared as a model of their crystalline protion and were subjected to introduction of FFAs. On these results, a possible distributing diagram of the introduced FFAs in a granule of the respective starch was proposed. Charakteristika der Einfuhrung von Fettsauren in Gajutsu- und Teppǒ-yuri-Starken. Starkekorner enthalten normalerweise naturlich auftretende Lipide, die fest in die Starkekorner eingeschlossen und mittles Et2O kaum entfernbar sind. - In dieser Arbeit wurden die Charakteristika des Einschlusses von freien Fettsauren (FFA) in Gajutsu (Curcuma zedoaria)-. Teppǒ-yuri (Lilium longiflorum)- und Kartoffelstarke, deren eingeschlossenen Lipide sehr gering sind (9, 2-25,6 mg%) sind, untersucht. Es wurde gefunden, das die gesattigten Fettsauren in groseren Mengen eingeschlossen waren (41.2-174,7 mg%) als die ungesattigten (15,9-46,5 mg%) und das sich die betreffenden Starken bezuglich ihrer Kapazitat, jede FFA einzuschliesen, voneinander unterschieden. Es wurden auch einige charakteristische Veranderungen im Verkleisterungsverhalten nach Einfuhrung von FFA in Abhangigkeit von den betreffenden Starken gefunden. Weiterhin wurden ihre Nageli-Amylodextrine als Modell ihres kristallinen Anteils dargestellt und der Einfuhrung von FFA unterworfen. Aufgrund der Ergebnisse wurde ein denkbares Verteilungsdiagramm der eingeschlossenen FFA in einem Korn der betreffenden Starke vorgeschlagen.

External preparation for skin

Abstract: PURPOSE:To obtain an external preparation for skin raising percutaneous absorption of kojic acid or its derivative and rapidly developing fair skinning action by using both kojic acid and/or its derivative and essence of a specific plant or a prescribed vegetable oil. CONSTITUTION:1. An external preparation for skin comprises kojic acid and/or its derivative and essence of one or more plants selected from the group consisting of Persea americana Mill, Semen panicimiliacei, Citrus aurantium L., Curcuma zedoaria Roscoe, Fucus versiculosus belonging to Phaeophyceae, Rubus idaeus L., Ribes nigrum, Chlorella pyrenoidosa, Symphytum pergium, Prunus persica, Solanum lycopericum L., Corylus avellana, Quillaiae and Parietaria officinalis. 2. An external preparation for skin comprises kojic acid and/or its derivative and one or more vegetable oils selected from avocado oil, Linseed oil, almond oil, kukui nut oil, walnut oil, safflower oil, shea butter, cherry pit oil, turpentine oil, peach kernel oil, palm oil, hazel nut oil, coix seed oil, macadamia nut oil, 1 sunflower seed oil and jojoba oil.
