新疆莴苣子挥发油成分气相色谱质谱法分析

目的:分析新疆莴苣子中挥发油成分。方法:采用水蒸气蒸馏法提取新疆莴苣子挥发油,运用气相色谱-质谱联用技术(GC-MS)进行分析鉴定。结果:共分离出71种成分,确认了其中62种成分,占挥发油总离子流的95.07%,其中主要成分为正己醇(36.31%)、正己醛(13.71%)、反式-2-辛烯-1-醇(8.09%)和2-正戊基呋喃(4.41%)。结论:该结果为新疆莴苣子资源的开发利用提供了理论依据。

维吾尔药材莴苣子的水分、灰分和浸出物的测定

目的测定莴苣子药材的水分、总灰分、酸不溶性灰分以及浸出物的含量,为制定其质量标准提供科学依据。方法按《中国药典》（一部）2010版附录IX H中水分测定法（烘干法）、附录IX K中的灰分测定法和附录X A中的浸出物测定法测定。结果莴苣子水分含量4.21%~5.47%,总灰分为4.21%~15.79%,酸不溶性灰分为0.63%~2.45%,水溶性浸出物（热浸）量为13.01%~16.09%。结论莴苣子水分含量不超过6.0%,总灰分不超过11.0%,酸不溶性灰分不超过2.0%,水溶性浸出物（热浸）量不低于13.0%,所得结果为建立药材标准提供了科学依据。

维吾尔药莴苣子中总黄酮含量的测定

目的：建立维吾尔药莴苣子中总黄酮含量的测定方法。方法：以芦丁为对照品,以亚硝酸钠—硝酸铝—氢氧化钠体系为显色剂,采用比色法测定总黄酮。结果：在0.2~1.2mg范围内线性关系良好（r=0.999 6）;平均回收率为103.3%,相对标准偏差（RSD）为0.7%（n=9）。结论：该方法简便、稳定、可靠,可作为莴苣子中总黄酮的含量测定方法。

The Role of Polyamine Oxidative Degradation in the Process of Lettuce Seed Germination

[Objective]The aim of this study was to understand the role of polyamine oxidative degradation in the process of lettuce seed germination. [Method]After lettuce seed soaking treatments with aminoguanidine （AG,a specific inhibitor of polyamine oxidases）,seed germination rate,activities of polyamine oxidase （PAO） and diamine oxidase （DAO）,change of endogenous polyamine and H2O2 content were determined. [Result]Compared with the control,AG treatment strongly inhibited the seed germination,which also had an extremely significant difference in seed germination rate after incubation for 12 h. During the seed germination,activities of PAO and DAO significantly changed,while their activities firstly increased and then decreased,then DAO and PAO reached peaks at 24 h and 48 h respectively. AG treatment was strongly inhibitory for activities of DAO and PAO,whose activities even disappeared after incubation with AG for 24 h and 36 h. During the seed germination,endogenous Put reduced sharply in the first 24 h,then reduced slowly in 24-60 h,while Spd decreased slowly in the early stage of germination,and then sharply declined after 48 h. However,Spm content was low but slightly increased,and the total polyamine gradually decreased. AG treatment could significantly increase endogenous polyamines,especially Put and Spd contents. During the seed germination,H2O2 content gradually increased,and had a peak from 36 to 48 h,then kept a high level at last. AG treatment could significantly reduce H2O2 content. [Conclusion]During the seed germination,the changes of endogenous polyamine and H2O2 content correspond with the changes of PAO and DAO activities,which indicate that there is an active polyamine metabolism of oxidative degradation during the lettuce seed germination.
