Chlorogenic acid (CGA), an ester of caffeic acid with quinic acid, is one of the most abundant polyphenol compounds in various agricultural products. CGA shows various biological properties, such as anti-oxidant, anti-viral, anti-carcinogenic and anti-inflammatory activities. We investigated suppressive effects of CGA on ovalbumin (OVA)-induced allergic asthma in mice and underlying mechanisms of them. CGA significantly reduced pulmonary eosinophilia and expression of IL-4, IL-5 and TNF-alpha in the lung as well as the serum levels of total and OVA-specific IgE, while CGA enhanced those of total and OVA-specific IgG3, of which isotype switching is down-regulated by IL-4. In vitro IgE production from LPS/IL-4-stimulated splenocytes was remarkably reduced by CGA, while that of IgG3 was enhanced. The Cepsilon germ line transcription, which is necessary for IL-4 mediated IgE isotype switching, was reduced by CGA in LPS/IL-4-stimulated splenocytes. IgE isotype switching is mediated via several transduction pathways, activating several molecules including STAT-6, NF-kappaB, ERK1/2, and JNK. Among the molecules, which were activated by IL-4/LPS, activation of STAT-6 and JNK was inhibited by CGA. 【链接】：http://www.ncbi.nlm.nih.gov/pubmed/20637839

It can be used in cosmetics formulations, but for this purpose its photochemical stability should be determined to ensure that the compound will not be degraded after UV radiation exposure. To evaluate this possibility, the concentration of a chlorogenic acid solution was determined by HPLC before and after UVA and UVB irradiation. The results indicate that chlorogenic acid is not degraded under UVA or UVB irradiation. 【链接】：http://www.ncbi.nlm.nih.gov/pubmed/20663081
