NY/T 1800-2009 大蒜及制品中大蒜素的測定 氣相色譜法
本標準規(guī)定了大蒜及制品（蒜粉、蒜片、蒜油）中大蒜素類硫醚化合物（二烯丙基三硫醚、二烯丙基二硫醚）含量的氣相色譜測定方法。
本標準適用于大蒜及制品（蒜粉、蒜片、蒜油）中二烯丙基三硫醚（DATS)和二烯丙基二硫醚（DADS）等大蒜素類硫醚化合物含量的測定。
本標準方法的檢出限為DATS0.9mg/kg；DADS為0.5mg/kg。
本標準方法檢測線性范圍為DATS：3.5mg/L~3500mg/L；DADS：2.0mg/L~2000mg/L。
浩瀚色譜（山東）應用技術開發(fā)有限公司利用氣相色譜－質譜聯(lián)用儀對大蒜油的部分組分進行了測定。確定了以二丙烯基三硫醚、二丙烯基二硫醚、甲基丙烯基三硫醚為主要成分的共 10種含硫化合物。根據面積歸一化法得到各組分的相對百分含量。

NY/T 1800-2009 Determination of Allicin in Garlic and Its Products by Gas Chromatography
This standard specifies the gas chromatographic method for determining the content of allicin sulfide compounds (diallyl trisulfide, diallyl disulfide) in garlic and its products (garlic powder, garlic tablets, garlic oil).
This standard is applicable to the determination of diallyl trisulfide (DATS), diallyl disulfide (DADS) and other allicin sulfide compounds in garlic and its products (garlic powder, garlic tablets, garlic oil).
The detection limit of this standard method is DATS0.9mg/kg; DADS is 0.5mg/kg.
The linear range of this standard method detection is DATS: 3.5mg/L~3500mg/L; DADS：2.0mg/L~2000mg/L。
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a gas chromatography-mass spectrometer to determine some components of garlic oil. A total of 10 sulfur-containing compounds were identified with dipropenyl trisulfide, dipropenyl disulfide, and methylpropenyl trisulfide as the main components. Obtain the relative percentage content of each component based on the area normalization method.
