摘要：采用水蒸气蒸馏法提取不同茬口当归药材挥发油,并用GC-MS法鉴定化学成分,归一化法测定相对含量,比较了不同茬口挥发油出油率及化学成分的差异。结果表明,正茬、迎茬、连作2a、连作3a栽培当归挥发油收率分别为0.95%、0.75%、0.70%、0.64%,挥发油中藁本内酯的相对含量分别为71.62%、49.04%、29.49%、59.58%,藁本内酯的异构化产物邻苯二甲酸酐和1,4-环己二烯1,2-二羧酐的相对含量分别为0.21%和4.47%、3.81%和8.55%、6.48%和10.65%、1.04%和5.33%。因此,与正茬栽培相比,连作栽培当归中挥发油的收率及其中藁本内酯的相对含量均明显降低,但挥发油的组分基本一致。
This research is to compare with tile yield and constituent of the essential oils extracted from the Angelica sinensis（ Oliv. ）Diels in different rotation system. Water steam and GC-MS were used. The yields of the essential oil of Angelica sinensis are O. 95% ,0.75% ,0.70% ,0.64%, respectively in potato-wheat-Angelica sinensis ,Angelica sinensis- wheat-Angelica sinensis, wheat-Angelica sinensis-Angelica sinensis, Angelica sinensis-Angelica sinensis-Angelica sinensis. The relative mounts of Ligustilide of essential oil are 71.62% ,49.04% ,29.49% ,59.58% ,respectively. The relative amounts of phthalic anhydride and 1,4-cyclohexadiene-1,2-dicarboxylic anhydride（ which is isomerization products form Ligustilide） of essential oil are 0.21% and 4.47% ,3.81% and 8.55% ,6.48% and 10.65%, 1.04% and 5.33%. The yields of the essential oil and the relative amounts of ligustilide are different considerably, while the constituents of the essential oil of Angelica sinensis from different rotation systems are identical.
