摘要
采用水蒸气蒸馏法提取不同生长年限肉桂(Cinnamomum cassia)树皮的挥发油,HPLC法测定桂皮醛的含量,比较2~5、5~7、7~10、11~15、20年以上肉桂树皮中挥发油和桂皮醛的含量,以期为肉桂树皮确定最佳采收期。结果表明,肉桂树皮中挥发油含量随着树龄增加而升高;主要有效成分-桂皮醛在5~7年达到峰值后,随着树龄增加而减少。
The volatile oil of Cinnamomum cassia bark with different ages was extracted by steam distilla- tion, and the content of cinnamaldehyde was determined by HPLC. The optimal harvesting period for 4＇. cas- sia bark was confirmed by comparing the content of volatile oil and cinnamaldehyde of 2 - 5, 5 - 7, 7 - 10, 11 - 15 and over 20 years old 4＇. cassia bark. Results showed that the volatile oil of 4＇. cassia bark increased with the increase of tree age. The main active ingredient, cinnamuraldehyde decreased with the increase of tree age after reaching the peak in 5 - 7 years.
