    4-羟基苯甲酰胆碱:白鳍金枪鱼中的一种天然产物
    摘要:
    摘要 已从白鳍金枪鱼的不同部位分离出胆碱酯的总成分。4-羟基苯甲酰胆碱已被鉴定并发现是白花蛇舌草种子提取物中数量占主导地位的胆碱酯之一。通过与合成参考化合物的比较,证实了新天然产物的身份。这种植物中存在几种不同的胆碱酯,但在幼苗、叶子和花序的提取物中,它们在数量上并不像种子中那样占主导地位。应用的改良离子交换技术似乎是从其他类型的酚类植物成分中分离和分离胆碱酯和胺的有效工具。

    摘要:
    从拟南芥和甘蓝型油菜种子制得的总胆碱酯级分通过毛细管LC / ESI-QTOF-MS和直接输注ESI-FTICR-MS进行分析。除了主要的芥子碱胆碱外,还可以基于精确的质量测量,碰撞诱导解离(CID)质谱的解释以及选定代表的合成,鉴定出30种酚类胆碱酯。迄今为止鉴定出的化合物包括取代的羟基肉桂酰基和羟基苯甲酰胆碱,各自的单己糖苷以及酚类胆碱酯和单木酚的氧化偶联产物。苯酚胆碱酯类可通过反相液相色谱很好地分离,并且可使用电喷雾电离质谱法以正离子模式灵敏地检测到。从分子离子获得的CID质谱图有助于表征此类化合物的类型和取代形式。因此,LC / ESI-MS / MS是对该化合物类别进行全面定性和定量分析的宝贵工具。版权所有©2008 John Wiley&Sons,Ltd.

    Disclosed embodiments concern a process for controlling plant pests, such as insects, nematodes, fungi, weeds, and combinations thereof, with specific embodiments being particularly useful for weed suppression. One disclosed embodiment comprises providing a plant, or a portion thereof, selected from the family Brassicaceae, particularly from the genera Brassica and Sinapis , and even more particularly from the genus Sinapis . Plant material is applied to soil prior to crop planting, simultaneously with crop planting, or subsequent to emergence of desired plants. The method may further comprise processing plant material. For example, with reference to Sinapis alba processing can include crushing the plants to obtain seed meal, which can be applied as obtained, or can be in other useful forms, such as pellets. Alternatively, effective glucosinolates may be extracted from plant material, either with or without first pressing the plant material. Extracted glucosinolates are applied to soil, followed by applying myrosinase, or alternatively the glucosinolate and myrosinase can be co-applied, to soil. Plant material or processed plant material may be combined with at least one additional material to form a composition, such as natural pesticides, natural fertilizers, synthetic fertilizers, synthetic herbicides, synthetic pesticide, surfactants, binders, colorants, pH adjusters/stabilizer, capsaicin, onion tissue, one or more microorganism, one or more products provided by a microorganism, or combinations thereof. The method also can include controlling the amount of water and/or pH added to soil, and or pH, to which the plant material, processed plant material, composition comprising plant material, or composition comprising processed plant material, is applied. The water and/or pH is selected to maintain bioactivity.
