Objectives To check marker content for appropriate quality control of Woohwangchungsimwon sterilized to ensure microbiological safety and to observe antioxidant activity for any changes in efficacy. Methods To measure any effects of sterilization on the effective compounds, 8 ingredients of Woohwangchungsimwon were screened for any changes in marker content using HPLC-DAD. Using the colorimetric method on the microplate reader any changes in total phenolic compound and flavonoid levels were observed. Antioxidant activity was measured using the DPPH, ABTS, and FRAP. Results Of the ingredients of Woohwangchungsimwon, 8 were subject to quantitative analysis before and after sterilization. 21.6 mg and 1.93 mg of Glycyrrhizin was found in Glycyrrhiza uralensis Fischer pre and post sterilization, respectively. Decursin found in Angelica gigas Nakai increased from 0.16 mg to 0.29 mg after sterilization. Bilirubin found in Gallstone of Bostaurusvar. domesticus increased from 0.24 mg to 0.33 mg. Cinnamic acid found in Cinnamomum cassia Blume increased from 0.02 mg to 0.05 mg. Ginsenoside Rb1 found in Panax ginseng C. A. Meyer decreased from 0.02 mg to 0.14 mg. Paeoniflorin found in Paeonia lactiflora Pallas increased from 1.05 mg to 1.13 mg. Amygdalin found in Armeniacae Amarum Semen increased from 2.68 mg to 2.83 mg. L-muscone found in Musk increased from 0.63 mg to 0.76 mg. As for total phenolic compound and total flavonoid content, there was a 1.22 and 4.15-fold increase. DPPH and ABTS increased by 20.45% and 20.69%, respectively. FRAP activity was 2.78 times more active post stabilization. Conclusions This study confirmed that high temperature high pressure steam sterilization, a method used to ensure microbiological safety of Woohwangchungsimwon, does not affect marker content; in other words, does not affect quality of the Woohwangchungsimwon. It could also be seen that total phenolic compound and flavonoid content increased after sterilization. An antioxidant activity test showed that there was significantly increased activity of antioxidants.

In this study, we evaluated the lipoprotein lipase (LPL) inhibitory activity of 11 water extracts derived from Cinnamomum cassia Blume, Sarcodon aspratus, Cordyceps militaris, Crataegus pinnatifida Bunge, Corni fructus, Allium cepa, Coix lacryma-jobi, Plantago asiatica L., Lentinus edodes, Rosa rugosa, and Foeniculum fructus. The results of the LPL secretion and activity assay showed Sarcodon aspratus (NE) extract have an LPL secretion inhibitory acitivity. The cause of reduction in LPL secretion after NE treatment was investigated using molecular biology methods. NE treatment affected the LPL content in cells, but did not affect LPL mRNA expression. It also increased the mRNA expression level of sortilin-related receptor LDLR class A (SorLA), a receptor that induces endocytosis and intracellular trafficking of LPL. Finally, cell fractionation revealed that NE treatment induced the expression of CCAAT-enhancer-binding protein beta ($C/EBP{\beta}$), a SorLA transcription factor, in the nuclei of 3T3-L1 adipocytes. These results show that NE's anti-obesity effect involves inhibition of LPL secretion through $C/EBP{\beta}$-mediated induction of SorLA expression.

The interest in and development of healthy foods and nutraceuticals have increased because of the trend for a health-oriented society. Cinnamon is used as a food ingredient as well as a herbal medicine because of its functional properties. In this study, flavoring compounds and antioxidative activities of cinnamon extracts were investigated with different extraction solvents and extraction methods. The contents of flavoring compounds such as coumarin, cinnamic acid, cinnamaldehyde, and cinnamyl alcohol were investigated. The contents of courmarin, cinnamic acid, and cinnamylaldehyde in 70% ethanol extract were higher than those in hot water and subcritical water extracts. The contents of courmarin, cinnamic acid, and cinnamaldehyde in subcritical water extract were higher than those in hot water extract, whereas the content of cinnamyl alcohol was lower. DPPH scavenging activity increased with increasing concentration of the extracts, and the 70% ethanol extract showed the highest antioxidant activity. The ascorbic acid content of the 70% ethanol extract was largest in the antioxidative activity measurement by FRAP analysis. The ascorbic acid contents of the hot water and subcritical water extracts were similar.
