中文摘要：
目的：研究梅花挥发油化学成分.方法：采用水蒸气蒸馏法提取梅花挥发油,气相色谱-质谱法对挥发油成分进行分离和鉴定,面积归一化法测定各成分的相对百分含量.结果：从梅花挥发油中共分离得到71个色谱峰,经NIST2008质谱数据库检索鉴定了其中51个成分的结构.结论：梅花挥发油化学成分包括醛类、酯类、有机酸、醇类和脂肪类化合物,其中主要成分按相对含量由高到低排序依次为苯甲醛（42.93％）,苯甲酸苄酯（9.16％）,二十一烷（7.96％）,二十三烷（7.39％）,棕榈酸（3.62％）和3-烯丙基-6-甲氧基苯酚（2.51％）.
英文摘要：
Objective：To study the chemical constituents of the volatile oil from the flower bud of Prunus mume.Method：The volatile oil was extracted by steam distillation and analyzed by GC-MS.The composition of the volatile oil was determined according to peak area normalization method.Result：Total 51 compounds were isolated and identified from the volatile oil of the flower bud of P.mume.Conclusion：Chemical constituents of the volatile oil from the flower bud of P.mume included aldehydes,esters,organic acids,alcohols and fatty compounds.The main components were benzaldehyde （42.93%）,benzyl benzoate （9.16%）,heneicosane （7.96%）,tricosane （7.39%）,n-hexadecanoic acid （3.62%） and 3-allyl-6-methoxyphenol （2.51%）.
