Objective:To evaluate toxic activities of essential oils obtained from Rosmarinus officinalis and lavandula stoechas against the fourth larval instars of Orgyia ***:A total of 1 200 larvae were divided into three groups Ⅰ,Ⅱ,Ⅲ.Group Ⅰ was to investigate the effect of extracted essential oils from these aromatic plants as gastric *** thuringiensis and ethanol were used as control *** Ⅱ was used as contact action and Group Ⅲ was used as fumigant *** and ethanol were used as control *** the three experiments,the effect of essential oils on larvae was ***:The chemical composition of essential oils from two medicinal plants was determined and,their insecticidal effects on the fourth larval slate of Orgyia trigotephras were *** two simples presented an insecticidal activity,nevertheless Rosmarinus officinalis essential oil was less efficient compared to lavandula stoechas one are ***:The relationship between the chemical composition and the biologieal activities is confirmed by the present *** the potential uses of these essential oils as bioinsecticides can he considered as an alternative to the use of synthetic products.

Quantitative Analysis of Lavender (<i>lavandula angustifolia</i>) Essential Oil Using Multiblock Data from Infrared Spectroscopy

引用

American Journal of Analytical Chemistry 2014年第10期5卷 633-645页

作者： Nathalie Dupuy Vincent Gaydou Jacky Kister Aix Marseille University LISA METICA EA4672 F-13397 Marseille 20 France

Near-infrared and mid-infrared spectroscopies were currently used to analyze natural compounds. During the last ten years various multiblocks methods were developed such as Concatenated PLS, Hierarchical-PLS (H-PLS), and MultiBlock-PLS (MB-PLS). These three algorithms were used to analyze 55 lavender (lavandula angustifolia) essential oil samples. The results obtained were compared to the ones obtained respectively in NIR and MIR ranges. The accuracies of the models depend on the spectroscopic technique, pretreatment and the PLS methods. The results showed that the choice of the factor numbers used to build the multiblock models was the most important parameter for the H-PLS and MB-PLS methods.

Clearance of Amyloid Beta Plaques from Brain of Alzheimeric Rats by lavandula angustifolia

Neuroscience & Medicine 2012年第4期3卷 362-367页

An important marker in neurodegenerative Alzheimer’s disease (AD) is abnormal production of amyloid beta (Aβ) peptide leading to formation of plaques in the brain. Through decreasing Aβ aggregates, anti-inflammatory agents, phagocytosis, and proteolytic enzymes are known to decline risk of Aβ plaque formation. In the previous study we showed that aqueous extract of lavandula angustifolia (lavender), with known anti-inflammatory effects, improves memory deficits in animal model of Alzheimer. Here, we assess if lavender play a role in clearance of Aβ plaques in the hippocampus. The Alzheimeric animals were created with intracerebroventricular injection of Aβ 1-42. To confirm formation of Aβ plaques, brain sections were stained by Congo red method. Twenty days post-injection they were administered with different doses (50, 100 and 200 mg/kg) of the aqueous extract of lavender for duration of 20 days. Our results demonstrated that 50 mg/kg of lavender not effectively influenced the Aβ plaques. On the other hand, the herbal medicine at the doses of 100 and 200 mg/kg markedly decreased the extent of Aβ aggregates. We concluded that the lavender extract dose dependently underlies elimination of Aβ plaques. The exact mechanism by which the herbal medicine removes the Aβ aggregates needs to be elucidated.

薰衣草(lavandula angustifolia Mill.)是一种名贵的天然香料植物,原产于地中海地区,是提取香料的主要植物。首先介绍薰衣草的由来并分析其经济价值,认为薰衣草精油品质高,气味纯正,芳香持久,不但具有药用价值和家庭保健、香熏美容功能,更是旅游观赏、美化环境的佳品,具有城市绿化、香化的功能,深受人们的喜爱。在分析薰衣草生长环境气候条件的基础上,探讨豫西山区栾川种植薰衣草的地理、气候条件适应性,认为栾川气候温润,夏不太热,冬不太冷,降水适中,日照充足,土壤肥沃,气候、地理条件非常适宜薰衣草生长。2010年在栾川县石庙镇观星村进行薰衣草引种栽培试验,经过3年的反复种植试验,引种栽培基本成功。通过引种栽培试验,从薰衣草生长对温度、水分、日照和土壤的依赖性、开花时间与温度的关系、播种和扦插繁殖与气象条件的关系、田间管理技术、气象灾害的应对防治措施和病虫害防治方法等几个方面研究出一套实用的薰衣草优质高产生产管理技术,可为熏衣草以后在豫西山区大面积推广种植提供可靠的气象保障技术。

为满足人们对薰衣草（lavandula angustifolia）苗木的需求并保持薰衣草母本的优良性状本,对薰衣草嫩枝扦插繁殖技术进行了研究。采用当年生薰衣草嫩枝为材料进行扦插试验,同时进行播种繁殖试验对比。结果表明：扦插技术生根快,为10~12d,生根率达到91.3%,扦插繁殖效率要高于播种繁殖。
