【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%。更多还原

【Abstract】 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’s 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.更多还原
