The current commercial ointment for atopic dermatitis treatment not only has a low moisture retention capacity but also a highly percentage of having recrudescence. In this study, a novel formable polyvinyl alcohol (PVA) gel was developed. The gel takes 30 min to form a membrane. The membrane has high water vapor transmission rate and its moisturizing ability to skin is increased by adding humectants. It inhibits Staphylococcus aureus from growing and does not irritate to the skin, calf, and arms. Animal test supports that the gel membrane incorporated with tacrolimus truly palliates symptoms of skin inflammation and itch. 相似文献

Polyglycerols and other polyols can be conveniently analyzed by partition HPLC on silica columns. Derivatization is not necessary. Compounds of this type are often found in the esterified form in food emulsifiers, and are set free upon saponification. They are also used as humectants and freezing point depressants, e. g. in soft ice cream. A chemical classification of food emulsifiers is given, and the separation and identification of their neutral polyols by HPLC is described. Lipid class HPLC of the intact esters is also briefly mentioned. 相似文献

湘西烟叶常规化学成分的聚类分析与综合评价 总被引:2,自引:0,他引:2
对2007年湘西五大主产烟区(龙山、桑植、吉首、怀化、永顺)765个烤烟样本进行了常规化学成分分析、常规化学组成相关性分析、聚类分析和评价。通过与优质烟叶常规化学组成相比较,发现龙山烟区下部烟叶品质较好,常规化学成分含量及各协调比值均达到了优质烟叶标准,其余依次为吉首烟区下部烟,桑植烟区中部烟、吉首烟区中部烟及永顺烟区中部烟。相关性分析表明,怀化烟区的钾含量与烟碱含量、永顺烟区的钾含量与氯含量都呈显著负相关。聚类分析表明,在这些烟区中,主要存在三类常规化学成分含量相似的烟叶,即龙山、怀化和吉首的中部烟;龙山、吉首与怀化的上部烟;龙山下部烟与永顺中部烟,它们可用于烟叶配打。 相似文献
