摘　　要：目的比较产地不同干燥加工方法对前胡药材质量的影响,筛选其最佳产地干燥加工方法。方法分别采用传统晒干、自然阴干和电热恒温鼓风干燥、真空干燥、红外干燥和真空冷冻干燥等干燥加工方法对前胡药材进行处理,以折干率、含水量、浸出物含量、颜色色度值以及4种香豆素类成分含量为指标,采用逼近理想解排序法进行综合质量评价。结果不同干燥加工方法下,12份前胡药材样品的折干率为31.56%~40.10%,含水量为6.96%~8.58%,浸出物含量为27.56%~43.10%,红绿度值为1.80~7.50,黄蓝度值为19.90~30.20,明度值为46.90~59.90;伞形花内酯、白花前胡甲素、白花前胡乙素、白花前胡E素的含量分别为≤0.05、3.70~14.05、0.72~2.37、0.81~3.90 mg/g,总含量为5.47~19.65 mg/g;40℃电热恒温鼓风干燥下的前胡药材综合得分最高。结论40℃电热恒温鼓风干燥是前胡药材最佳的产地干燥加工方法。OBJECTIVE To compare the effects of different drying processing methods in the producing area on the quality of Peucedanum praeruptorum,and screen the optimal drying processing in the producing area.METHODS P.praeruptorum was processed by traditional drying in the sun,drying in the shade,and modern drying processing methods such as electric heating and blast drying,vacuum drying,infrared drying,and vacuum freeze drying.Technique for order preference by similarity to ideal solution(TOPSIS)method was used to perform the comprehensive quality evaluation using drying rate,water content,extract content,color chroma value,and the contents of 4 coumarins as indexes.RESULTS Under different drying processing methods,the drying rates of 12 samples of P.praeruptorum were 31.56%-40.10%;the moisture contents were 6.96%-8.58%,and the extract contents were 27.56%-43.10%;the color chroma values red green degree,yellow blue degree and brightness were 1.80-7.50,19.90-30.20,46.90-59.90,respectively.The contents of umbelliferolactone,praeruptorin A,praeruptorin B and praeruptorin E were≤0.05,3.70-14.05,0.72-2.37,0.81-3.90 mg/g,respectively;and the total contents were 5.47-19.65 mg/g.The comprehensive score of P.praeruptorum was the highest under the condition of drying at 40℃by electric heating and blast.CONCLUSIONS The drying method at 40℃by electric heating and blast is the first choice for P.praeruptorum in the producing area.
