【摘要】 目的比较巴西肉桂CANELA与中国肉桂中桂皮醛的含量差异,为肉桂药材的新品种选育及品质评价提供科学依据和方法。方法采用高效液相二极管阵列检测法分别测定6批巴西肉桂CANELA与中国肉桂中桂皮醛的含量。结果 6批巴西肉桂CANELA及中国肉桂中桂皮醛的平均含量分别为18.3%和5.27%,均明显高于2010年版《中华人民共和国药典》(一部)规定的1.5%。结论以桂皮醛为指标进行评价,巴西肉桂CANELA品质优于中国肉桂。本研究为确定巴西肉桂CANELA化学成分与药用价值奠定了基础,也可为肉桂药材品种的资源普查、新品种选育、品质评价等提供科学参考。更多还原

【Abstract】 Objective To compare the contents of Cinnamaldehyde between Brazilian CANELA.and Chinese Cinnamomum zeylanicum Bl. and provide the reference for the breeding of variety and quality control of Cinnamomum zeylanicum Bl.. Methods Take 6 Brazil CANELA. and 6 Chinese Cinnamomum zeylanicum Bl. as the research objects. The contents of Cinnamaldehyde in Brazil and Chinese Cinnamomum zeylanicum Bl. were determined by High Performance Liquid Chromatography. Chromatographic column: waters sunfire C18 chromatographic column( 150 mm x 4. 6 mm,5 microns); mobile phase: acetonitrile: water( 35: 75); detection wavelength: 290 nm; flow rate: 1 m L / min; injection volume: 10μL;column temperature: 30℃. Results The Cinnamaldehyde,which is the index component in Cinnamomum zeylanicum Bl. was found both in Brazil and Chinese sample. The contents of Cinnamaldehyde Brazilian CANELA.. and Cinnamomum zeylanicum Bl. were 18. 3% and 5. 27%,respectively,They are greater than the stipulated 1. 5% in the 2010 edition of Chinese pharmacopoeia. Conclusion The content of Cinnamaldehyde in Brazilian CANELA was significantly higher than the Chinese Cinnamomum zeylanicum Bl.. The study provides the reference for the census of variety resources,breeding of new variety and quality control of Cinnamomum zeylanicum Bl.. It also lays the foundation for the chemical composition and medicinal research of Cinnamomum zeylanicum Bl..更多还原
