The essential oil of Litsea cubeba (EOLC) is obtained by steam distillation from the pepper-like fruits tree Litsea cubeba. The EOLC consists of about 29 active compounds. Among them, citral is the main component;the content of citral is nearly 80% of the EOLC. Due to the special function group, citral is easy to react with many chemicals. Thus, EOLC is usually applied as starting material to carry out aldol condensation, reduction, and six-member ring forming reaction. The EOLC is extensively employed to synthesis of geranal nitriles, pseudonoe, ionone, methyl ionone, Vitamin E and Vitamin A. These products are broadly applied in the fields of fragrance, perfume, medicine and so on. This paper presents comprehensive utilization of EOLC as raw materials to synthesize many active chemicals.展开更多
为了探究山苍子精油中主要成分的绝对含量,建立了一种气相色谱-质谱/选择离子扫描(gas chromatography mass spectrometry/selective ion monitoring,GC-MS/SIM)方法,对其中主要成分(α-蒎烯、β-蒎烯、D-柠檬烯、1,8-桉叶素、芳樟醇、...为了探究山苍子精油中主要成分的绝对含量,建立了一种气相色谱-质谱/选择离子扫描(gas chromatography mass spectrometry/selective ion monitoring,GC-MS/SIM)方法,对其中主要成分(α-蒎烯、β-蒎烯、D-柠檬烯、1,8-桉叶素、芳樟醇、香茅醛、柠檬醛)进行了定性和定量分析。该方法简便、高效,在25 min内山苍子精油中各成分分离良好。各成分在一定范围内均线性关系良好(R2>0.999),精密度、稳定性及重复性均符合要求,平均加标回收率为93.40%~107.35%。结果表明:该方法符合方法学验证要求,可用于山苍子精油的多成分含量测定,并为其质量评价提供依据。展开更多
山苍子是我国特有的木本油料植物和传统中草药,具有很高的药用价值。本文以Web of Science和CNKI数据库为来源,利用文献分析软件Cite Space,结合作者、机构、关键词等指标,对近20年国内外关于山苍子的研究前沿、热点以及发展趋势进行梳...山苍子是我国特有的木本油料植物和传统中草药,具有很高的药用价值。本文以Web of Science和CNKI数据库为来源,利用文献分析软件Cite Space,结合作者、机构、关键词等指标,对近20年国内外关于山苍子的研究前沿、热点以及发展趋势进行梳理。自2000年以来,山苍子产业处于稳定发展的阶段。中国是世界上研究山苍子的主要国家,基于我国的资源优势,中国林业科学研究院及其团队发表外文文献居多,主要作者为汪阳东、陈益存,在国际上具有较高影响力,而国内发文最多的机构是中南林业科技大学。近些年关于山苍子的研究热点主要集中在香料合成、饲料加工、杀虫除霉等方面,涉及化学、轻工业、农学等多个领域,具有广阔的发展前景。湖南省是我国今后山苍子研究发展的主要省份,未来将对山苍子精油与核仁油分别展开深入研究,以增加其产业附加值。展开更多
