Methods Six components, phenylpropyl acetate, cinnamyl acetate, cinnamaldehyde, cinnamyl alcohol, coumarin, and cinnamic acid were used as characteristic markers, and an optimized TLC method was developed. Results The TLC profile of cassia bark is similar to its closely related variety Cinnamomum cassia Presl var. macrophyllum Chu but significantly different from other six Cinnamomum species. High content of phenylpropyl acet...展开更多

The control group received the corn soybean meal based diet. In the treatment groups the basal diet was supplemented with one of following 0.2%, 0.4% and 0.6% Thyme and Mint extracts. Triglyceride was significantly decreased by addition of 0.2% and 0.4% of Thyme extract （TE）. The TE supplemented diets contained significantly lower cholesterol concentration and low density lipoprotein compared to the control diet. High density lipoprotein content was not significantly affected by dietary treatments. Likewise, differences among groups were not significant for hematocrit and hemoglobin level. The addition of Mint extract （ME） to the broiler diet led to a significant reduction in the triglyceride, cholesterol concentration and LDL. Differences among groups were not significant for HDL, hematocrit, or hemoglobin level. The results showed that both of TE and ME supplementation significantly decreased plasma level of triglycerides and LDL-cholesterol were also numerically increased with the addition of both TE and ME.展开更多
