北京药用植物园引种黄皮树的质量评价

为探究北京药用植物园引种黄皮树的药材质量,扩大其种植区域,测定北京药用植物园引种黄皮树干燥树皮的水分、总灰分、浸出物、小檗碱、黄柏碱含量,并与主产区栽培黄皮树、市售黄柏药材进行比较,综合评价北京药用植物园引种黄皮树的药材质量。结果显示,北京药用植物园引种黄皮树干燥树皮水分含量为(5.63±0.12)%、总灰分含量为(7.30±0.12)%、浸出物含量为(23.83±1.68)%、小檗碱含量为(7.02±0.25)%、黄柏碱含量为(0.44±0.01)%,各项指标均符合2015版《中华人民共和国药典》（一部）对黄柏药材的要求;与主产区栽培及市售黄柏相比,其指标性成分含量处于中等水平。北京药用植物园引种黄皮树质量良好,可作为黄柏药材使用,研究结果可为黄柏药材栽培产区的北移提供科学依据。

Quality Evaluation of Introduced Phellodendron chinense in Beijing Medicinal Plant Garden

The paper aims to explore the quality and expand the planting area of the Phellodendron chinense introduced into Beijing Medical Plant Garden. The water, total ash, extract, berberine and phellodendron content of the bark of P. chinense introduced into Beijing Medical Plant Garden were determined and compared with the cultivated P. chinense bark in the main producing area and the commercial Phellodendri chinensis cortex, and the quality of the introduced phellodendron bark in Beijing Medical Plant Garden was comprehensively evaluated. The results showed that the moisture content, total ash content, extract content, berberine content and phellodendron content of the dry bark of P. chinense introduced in Beijing Medical Plant Garden was (5.63±0.12)%, (7.30±0.12)%, (23.83±1.68)%, (7.02±0.25)% and (0.44±0.01)%, respectively, which met the requirements of Phellodendri chinensis cortex of Pharmacopoeia of the People's Republic of China(2015, PartⅠ). Compared with the cultivated and commercial Phellodendri chinensis cortex in the main production area, the index components’ content of Phellodendri chinensis cortex from Beijing Medicinal Plant Garden belonged to the middle level. The results show that the quality of the P. chinense introduced into Beijing Medical Plant Garden is good and it could be used as Phellodendri chinensis cortex, which could provide a scientific basis for the northward migration of the cultivation area of Phellodendri chinensis cortex.
