In this study, quantitative and pattern recognition analysis for the quality evaluation of Cinnamomi Ramulus and Cinnamomi Cortex using HPLC/UV was developed. For quantitative analysis, three major bioactive compounds were determined. The separation conditions employed for HPLC/UV were optimized using an ODS $C_{18}$ column ($250{\times}4.6$ mm, 5 ${\mu}m$) with gradient conditions of acetonitrile and water as the mobile phase, at a flow rate of 1.0 mL/min and a detection wavelength of 265 nm. This method was fully validated with respect to linearity, accuracy, precision, recovery, and robustness. The HPLC/UV method was applied successfully to the quantification of three major compounds in the extract of Cinnamomi Ramulus and Cinnamomi Cortex. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of thirty eight Cinnamomi Ramulus and thirty five Cinnamomi Cortex samples. The results indicate that the established HPLC/UV method is suitable for quantitative analysis.

Objective : In this study, we performed quantitative comparison on the content of 10 marker compounds in cinnamon barks from different species and found chemical discrimination between genuine Cinnamomum cassia and other Cinnamomum species (Non C. cassia). Methods : Cinnamon bark samples were extracted using the ultrasonication in 100% methanol for 30 minutes. The samples were analysed using high-performance liquid chromatography with statistical analysis. Results : The analytical method developed in this study met all validation criteria and was applied to the quantification of the 10 marker compounds in cinnamon bark samples. The major chemical discrimination of C. cassia were identified as low content of epicatechin and eugenol, and high contents of benzaldehyde, cinnamaldehyde and cinnamic acid compared to other Non C. cassia samples. Especially, among other compounds, the content of cinnamaldehyde was the highest in the C. cassia and Non C. cassia samples. The result of principal component analysis showed that the samples of C. cassia and Non C. cassia were clearly differentiated via benzaldehyde, cinnamaldehyde, cinnamic acid, eugenol, and epicatechin, which influenced on clustering C. cassia and Non C. cassia samples. Conclusion : C. cassia and Non C. cassia samples were chemically discriminated using the quantitative HPLC analysis. Based on this, it is possible to control the quality of herbal medicines containing Cinnamomi Cortex. It is necessary to further improve the accuracy of discrimination between C. cassia and Non C. cassia species to evaluate cinnamon bark quality.

Objectives : Recently, natural bioactive components catch a major attention for their potent anticarcinogenic activity. In this study, the inhibitory effect of Cinnamomi Cortex (CC) was examined in PC3 prostate cancer cells. Methods : The toxicity of CC extract was evaluated with cell viability and cell morphology. The activity of Yes associated protein (YAP) was tested with qRT-PCR for the target gene expression such as CTGF and AMOTL2. Western blotting was performed for the evaluation of phospho-YAP level. For cell motility analysis, cellular motility was imaged by live imaging system for 6 hr. Successive images were used for the generation of movie file. Using this movie file, cellular migration was manually tracked and analyzed using time-lapse microscope and Fiji software. Results : Cytotoxicity of CC extract was not detected at $500{\mu}g/m{\ell}$ or below concentration. Although $500{\mu}g/m{\ell}$ of CC extract reduced CTGF and AMOTL2 gene expression as YAP target genes, it was not statistically significant (CTGF expression P=0.0605, AMOTL2 expression P=0.4478). However, phosphorylated YAP was highly enhanced by CC extract treatment, when normalized with total YAP protein expression, suggesting YAP activation was inhibited. Finally prostate cancer cell motility was markedly reduced by $500{\mu}g/m{\ell}$ of CC extract. Conclusions : CC extract suppresses cancer cell motility and migration ability through inhibiting YAP activation without prostate cancer cell death, suggesting that this herb might be effective therapeutic drug for prostate cancer metastasis.

To evaluate the quality of the crude drugs using three kinds of Cinnamomum Cortex (CC), Vietnamese CC (VCC, the stem bark of Cinnamomum obtusifolium), periderm-peeled Chinese CC (PPCC, periderm-peeled stem bark of C. cassia), Chinese CC (CCC, stem bark of C. cassia) and a Cinnamomi Ramulus (CR, the twig of C. cassia), the four essential oils were prepared by steam distillation method. Cinnamaldehdye (CAN) and an unknown substance tentatively named hydroxy-cinnamaldehdye(HCNA) were detected in the four essential oils by gas chromatography-mass spectrometry, the contents of which are significantly different one another. Vietnamese CC had the highest content of HCNA whereas CR had the highest CAN content and the lowest HCNA. Vietnamese CC exhibited the greatest cytotoxic activity against the cancer cell lines, A549, HepG-2, HL-60, P-388, U-937, and KB and CR the lowest cytotoxicity. Contents of CAN and HCNA in CCC and PPCC are positioned between VCC and CR. These results suggest that measurement of HCNA and cytotoxicity may determine the quality of CC and CR.

Objective : This study investigated the anti-diabetic effects of DM1, a herbal mixture with Atractylodis Rhizoma, Anemarrhenae Rhizoma, and Cinnamomi Cortex in high fat diet (HFD)-induced diabetic mice and the mechanism in C2C12 mouse skeletal muscle cells. Methods : The C57B/6 mice were fed high fat for 12 weeks, and then administrated DM1 extract (500 mg/kg, p.o.) for 4 weeks. The changes of body weight, calorie and water intakes, fasting blood glucose levels and the serum levels of glucose, insulin, triglyceride, HDL-cholesterol, AST and ALT were measured in mice. The histological changes of liver and pancreas tissues were also observed by H&E stain. C2C12 myoblasts were differentiated into myotubes and then treated with DM1 extract (0.5, 1, and 2 mg/㎖) for 24 hr. The expression of myosin heavy chain (MHC), PGC1α, Sirt1 and NRF1, and the AMPK phosphorylation were determined in the myotubes by western blot, respectively. Results : The DM1 extract administration significantly decreased the calorie and water intakes, glucose, triglyceride, AST and ALT levels and increased insulin and HDL-cholesterol in HFD-induced diabetic mice. DM1 extract inhibited lipid accumulation in liver tissue and improved glucose tolerance. In C2C12 myotubes, DM1 treatment increased the expression of MHC, PGC1α, Sirt-1, NRF-1 and the AMPK phosphorylation. Conclusion : In our results indicate that DM1 can improve diabetic symptoms by decreasing the obesity, glucose tolerance and fatty liver in HFD-induced diabetic mice, and responsible mechanism is might be related with energy enhancement.
