摘要
大蒜植株中含有一定量具有生理活性及药理性质的有机硫化物,采用有机溶剂提取法和气相色谱—质谱(GC-MS)技术,对4个不同生长时期新鲜蒜叶提取液中的有机硫化物进行分析和鉴定。四个时期包括:生长到1个月、生长到2个月、生长到5个月(包括2～3个月的冬季休眠期)和生长到7个月(成熟)。结果表明,蒜叶提取液中有机硫化物主要成分可分为3类:烯丙基类硫化物、杂环类硫化物和烷基类硫化物,其中包含一定量的大蒜油成分。在大蒜植株生长过程中,各阶段蒜叶提取液组分及相对含量有一定的差别,在其生长到2个月和7个月时,提取液中的有机硫化物含量相对较高。其中具有代表性的二烯丙基二硫醚在4次试验提取液中的相对含量分别是6.09%,15.67%,2.35%和13.09%,3-乙烯基-1,2-二硫杂-5-环己烯在4次试验中的相对含量分别是4.00%,10.58%,2.30%和14.9%。
Based on the biological activity and pharmacological effects of garlic , we analyzed and identified organic sulfides contained in fresh garlic leaf extracts at four developmental stages with GC -MS by organic solvent extraction method.Four different periods included： one month, two months, five months （including 2 -3 months of winter hibernation） and seven months （mature） after planting.The results showed that the main composition of garlic leaf extracts could be divided into three categories： allyl sulfides, heterocyclic sulfides and alkyl sulfides , containing a number of components of garlic oil .Garlic leaf extract＇ composition and relative contents varied during development and ripening.A significant increase in organic sulfur was observed when the garlic was two months and seven months old.The most representative compositions were diallyl disulphide and 3-vinyl-1, 2-dithiacyclohex-5-ene, whose relative contents were 6.09%,15.67%,2.35%and 13.09%;4.00%,10.58%,2.30%and 14.9%, respectively .
