【摘要】 采用水蒸气蒸馏法对不同栽培方式的卷丹鳞茎挥发油进行提取,并用气相色谱—质谱联用技术(GC-MS)对挥发油成分进行了分析。结果表明,从遮荫栽培的卷丹鳞茎中分离出40种化合物,并鉴定出了35种;从露地栽培的卷丹鳞茎中分离出30种化合物,鉴定出了28种;从大棚栽培的卷丹鳞茎中分离出36种化合物,鉴定出了34种。用气相色谱面积归一化法测定了各成分的相对百分含量,其中在遮荫栽培的卷丹鳞茎中检测到6种脂肪酸,占挥发油总量的71.44%;在露地栽培的卷丹鳞茎中检测到5种脂肪酸,占总量的16.94%;在大棚栽培的卷丹鳞茎中检测到6种脂肪酸,占总量的52.87%。从挥发油种类及含量因素考虑,卷丹最适宜的栽培方式为遮荫栽培。更多还原

【Abstract】 The volatile oil in the bulbs of L.lancifolium Thunb.was extracted by steam distillation.The chemical components of the volatile were analyzed by GC-MS.The results showed that forty compounds were found and thirty five compounds were identified from shading cultivars;thirty compounds were found and twenty-eight compounds were identified from open field cultivars;thirty-six compounds were found and thirty-four compounds were identified from protected cultivars.the relative contents of constitutes were determined by area normalizing method.Six kinds of fatty acid were found from shading cultivars,the amount accounting for 71.44% in all the volatile oil;five kinds of fatty acid were found from open field cultivars,the amount accounting for 16.94% in all the volatile oil;six kinds of fatty acid were found from protected cultivars,the amount accounting for 52.87% in all the volatile oil.Considering from the variety and content of volatile oil,shading cultivars is the befitting cultivated mode.更多还原
