| Abstract
|
| [Objective] To investigate the growth status and effective ingredient content differences of different ecotype germplasms from 10 producing areas after being introduced in Tianjin,high-quality varieties suitable for promotion and planting in this area were selected.[Methods] Different germplasm resources of Mentha haplocalyx were treated by randomized block design. The growth pattern,biomass and active component content were used as the evaluation index,the content of the essential oil of Mentha haplocalyx was determined according to the volatile oil determination method,the content of total flavonoids was determined by UV-VIS method,and the content of organic acids was determined by HPLC-UV method.[Results] After being introduced to Tianjin,Mentha haplocalyx from Anguo,Hebei Province,and Yancheng,Jiangsu Province were thick and strong,with many branches,large biomass and high yield;based on the content of volatile oil in the pharmacopoeia index components,the contents of medicinal materials from different producing areas meet the prescribed standards;based on the content of total flavonoid,the content of each origin was between 96.36~168.21 mg/g. The highest were the Mentha haplocalyx from Anguo,Hebei Province and Yancheng,Jiangsu Province,at 168.21 mg/g and 165.68 mg/g respectively;based on the content of organic acids,the content of each variety varied greatly. The caffeic acid content of Mentha haplocalyx from Yancheng,Jiangsu Province was as high as 0.53 mg/g. The content of rosmarinic acid in Anguo,Hebei Province was as high as 13.59 mg/g.[Conclusion] Mentha haplocalyx has a good ecological adaptability,and the Mentha haplocalyx from Anguo,Hebei Province and Yancheng,Jiangsu Province growed well in salinized soil field in Tianjin. Therefore,it is feasible to introduce and popularize Mentha haplocalyx in Tianjin. |
