Methods: In alkaline condition, reaction between amino acids and phenylisothiocyanate formed a derivant of phenylisothiocyanate-amino acid. For RP-HPLC, the Diamonsil C18 column 250 mm×4.6 mm,5 μm） and binary gradient elution were used. The mobile phase A was 0.1 mol/L sodium acetate solution-acetonitrile (93∶7） and the mobile phase B was acetonitrile-water（80∶20）. The detecting wavelength was 254 nm.

The sample was mixed with norleucine as the internal standard, then derivatized with phenylisothiocyanate and analyzed on a Kromasil C 18 column at 38 ℃, using gradient elution with detection at 254 nm.

在Koop等[3] 和Bidling meyer等[4 ]证明异硫氰酸苯酯和氨基酸的反应产物苯基硫酸盐氨基酸的稳定性后，PITC才直接用于氨基酸分析。

The sample was mixed with norleucine as the internal standard, then derivatized with phenylisothiocyanate and analyzed on a Kromasil C18 column at 38 ℃, using gradient elution with detection at 254 nm.

以正亮氨酸为内标物，异硫氰酸苯酯为柱前衍生剂，用C18色谱柱在柱温38 ℃下采用二元梯度洗脱，于254 nm波长处检测。

The volatile components were separated and identified using GC-MS technique. RESULTS Seven ingredients were. isolated: 2-ethyl-hexyl-adipate (66.5%), 1-methoxy-4-(1-propenyl)benzene (12.5%), isopropyl isothiocyanate (6%), isobutylisothiocyanate (6%), 6-methyl-5-heptene-2-one (3.5%), benzaldehyde (1.4%), phenylacetaldehyde (0.8%).

结果 分离出7个成分，采用峰面积归一化法确定了各成分的相对含量，分别为66.5%双－2-乙基己基－己二酸、12.5%1-甲氧基－4-（1-丙烯基）苯、6%异硫氰酸异丙酯6%、6%异硫氰酸异丁酯、3.5%6-甲基－5-庚烯－2-酮、1.4%苯甲醛、0.8%苯乙醛。

Plant volatiles as allyl isothiocyanate , Z-3-hexen-1-ol , and Z-3-hexenyl acetate can attract DBM effectively and they have enhanced effect on captures of sex lure.

同时研究了植物挥发物异硫氰酸丙烯酯、青叶醇（Z-3-hexen-1-ol）、乙酸顺-3-己烯酯（Z-3-hexenyl acetate）对小菜蛾的诱捕作用及对性信息素诱捕作用的影响。
