In this paper, we studied comparatively volatile fractions obtained by hydrodistillation from 5 samples of lavender flowers (L. angustifolia ssp. angustifolia, L. hybrida, L. angustifolia spp. pyrenaica, L. angustifolia spp. angustifolia cv. Munstead and cv. Hidcote blue) cultivated during 2009 in the Botanical Garden from Galati.
The essential oils have been characterized using gas-chromatography and mass spectroscopy analysis (GC-MS).
The main compounds in all lavender volatile oils were: linalool (20.60%-35.99%), linalyl acetate (12.58%-19.65%), lavandulyl acetate (3.74%-10.48%), t-p3-ocimene (1.26%-9.23%), a-terpineol (3.67%-6.73%), nerol (0.81%-3.32%), neryl acetate (0.95%-3.64%) and beta-caryophyllene (0.93%-2.43%).
None of the separated volatile fractions met the minimal quality parameters for the standard volatile oil of fine lavender used in aromatherapy. Low concentration in monoterpene esthers could be explained by the fact that, on one hand, the average daily temperature during the blooming period is below the one from Mediterranean Sea area, and, on the other hand, the city of Galati is only 42 meters above the sea level (the volatile oil from fine lavender used in aromatherapy is obtained from plants cultivated at 800-1200 meters altitude).
在本文中,我们比较研究了2009年在加拉茨植物园种植的5种薰衣草花(狭叶薰衣草亚种狭叶薰衣草、杂交薰衣草、比利牛斯薰衣草、狭叶薰衣草品种芒斯特德和希德科特蓝)经水蒸馏得到的挥发性成分。
采用气相色谱和质谱分析(GC-MS)对精油进行了表征。
所有薰衣草挥发油中的主要化合物为:芳樟醇(20.60%-35.99%)、乙酸芳樟酯(12.58%-19.65%)、乙酸薰衣草酯(3.74%-10.48%)、反式-β-罗勒烯(1.26%-9.23%)、α-萜品醇(3.67%-6.73%)、橙花醇(0.81%-3.32%)、乙酸橙花酯(0.95%-3.64%)和β-石竹烯(0.93%-2.43%)。
分离出的挥发性成分均未达到用于芳香疗法的优质薰衣草标准挥发油的最低质量参数。单萜酯含量低一方面可能是由于花期的日均温度低于地中海地区,另一方面是因为加拉茨市海拔仅42米(用于芳香疗法的优质薰衣草挥发油是从海拔800-1200米处种植的植物中提取的)。
