摘要：以当归“岷归1号”为研究对象,探究平衡脱水干燥(P)、阴干(Y)、晒干(S)及熏干(X)4种干燥方式对药材性状、显微结构、活性成分和抗氧化物酶活性的影响。结果表明:P和Y的当归色泽均匀鲜亮、表面皱纹疏松,外观品相较好;P与X当归的油室平均直径和淀粉粒密度均高于X与Y的;P当归的阿魏酸、多糖、挥发油提取率、浸出物、洋川芎内酯A、正丁基苯酞、藁本内酯和欧当归内酯A含量显著高于Y、S及X(P<0.05);不同干燥方式对当归抗氧化物酶活性影响显著(P<0.05),其中S当归的SOD、CAT、POD活性和GSH含量显著高于P、Y和X。P当归的总蛋白含量最高(达18.31 mg prot/g),S当归的最低(为3.05 mg prot/g);SOD、POD和CAT活性及GSH含量与当归多糖、浸出物、总蛋白、挥发油提取率、阿魏酸及苯肽类成分呈显著相关(P<0.05);PCA结果为:P>Y>X>S。综合分析可知,平衡脱水干燥的当归药材具有外观较好、油室较大、活性成分含量较高。因此,平衡脱水干燥技术可在当归药材产地干燥加工中加以推广应用。
The present work aimed to investigate the effects of four kinds of drying modes of balanced dehydration drying(P),shade drying(Y),sun drying(S)and fumigation drying(X)on appearance,micro structure,active components and antioxidant enzyme activities of“Mingui No.1”of Chinese Angelica(CA).Results indicated that CA of P and Y had even and bright color,the surface wrinkles were loose,and the appearance was good;the average diameter of an oil chamber and starch density of CA of P and X were higher than those of X and Y;ferulic acid of CA of P,polysaccharides,volatile oil extraction rate,extracts,ligustilide A,n-butylphthalide,ligustilide,and angelica lactone A contents were significantly higher than Y,S,and X(P<0.05);The antioxidant activity of CA under different drying methods was significantly affected(P<0.05),and the SOD,CAT,POD activity and GSH content of CA of S were significantly higher than those of P,Y and X.P had the highest total protein content(up to 18.31 mg prot/g),and CA of S had the lowest(3.05 mg prot/g);SOD,POD and CAT activities,GSH content and polysaccharides,extracts,total protein,volatile oil extraction rate,ferulic acid,and phenopeptide components were significantly correlated;PCA results were:P>Y>X>S.Based on the comprehensive analysis,compared with traditional drying methods,the dried CA by balanced dehydrated has a better appearance,a larger oil chamber,and a higher active ingredient content.Therefore,the balanced dehydration drying technology can be popularized and applied in the drying process of the origin of CA.
