28、酯:ethyl acetate 挥发油:volatile oil 硫酸:sulfuric acid 盐酸:hydrochloride acid 氢氧化钠:sodium hydroxide 光谱:spectrum 结构:structure 相当大的:considerable 纸层析纸层析:Paper Chromatography(PC) One of the main advantages of PC is the great convenience of carrying out separations simply on sheets of filter paper, which serve

29、 both as the medium for separation and as the support. Another advantage is the considerable reproducibility of Rf values determined on paper, so that such measurements are valuable parameters for use in describing new plant compounds. 纸层析主要优点之一是他十分的方便: 仅用滤纸就可进行分离, 滤纸同时作为分离和支 持的介质。它的另一个优点是 Rf 值有相当好的

30、重现性,因此可用来描述新的天然化合物。 In PC, compounds are usually detected as coloured or UV-fluorescent spots, after reaction with a chromogenic reagent, used either as a spray or as a dip. 在纸层析中, 化合物通常用喷雾法或浸渍法与显色剂反应显色斑或显 UV-荧光斑点而被 检出。 薄层层析:薄层层析:Thin Layer Chromatography(TLC) 因素:factor 含水量:moisture content Another

31、reason for still using plates coated in the laboratory is that the moisture content of the silica gel can be controlled, a factor which is critical for some separations. 现在, 仍在使用实验室里铺的板的另一个原因是硅胶的含水量容易控制, 这在某些分离 过程中是关键性因素。 Rf values are considerably less reproducible than on paper and it is therefore

32、 essential to include one or more reference compounds as markers. TLC 的 Rf 值的重现性比 PC 差许多,所以有必要用一到几个参照化合物作为对照。 高效液相色谱:高效液相色谱:High Performance Liquid Chromatography(HPLC) HPLC is mainly used for those classes of compound which ara non-volatile, e.g. higher terpenoids, phenolics of all types, alkaloids

33、, lipids and sugars. HPLC 主要用于非挥发性的物质的分离,如高级萜类,各类酚性化合物,生物碱,脂类 和糖。 紫外紫外-可见吸收光谱可见吸收光谱:Ultraviolet-Visible(UV-VIS)spectroscopy The portion of the electromagnetic spectrum that lies just beyond the infrared reigon is visible light. 电磁谱中位于红外以外的部分是可见光区。 红外光谱:红外光谱:Infrared Spectroscopy(IR) While NMR spectr

34、oscopy is,in general,more revealing of the structure of an unknown compound,IR still retains an important place in the chemists inventory of spectroscopic methods because of its usefulness in identifying the certain functional groups within a molecule. 虽然现在核磁共振光谱总的来说更能解释一个未知化合物的结构, 红外光谱在化学家所 使用的光谱方法

35、中保留着很重要的地位。因为它对鉴定分子中某些官能团的存在很有用。 An advantage to using wave numbers is that they are directly proportional to energy while wavelengths are inversely proportional to energy. 用波数作单位的一个优点是它与能量成正比,而波长与能量成反比。 This is the region in which the vibrations characteristic of particular functional groups are fo

36、und. 某些官能团与其振动的特征频率对应的关系在这个区域内能体现出来。 It is here that the pattern of peaks varies most from compound to compound. 每一个化合物在这个区域内均有不同的吸收峰形。 质谱:质谱:Mass Spectroscopy(MS) Mass spectroscopy is the instrumental method of structure determination that is most different from the others in the group discussed in

37、 this chapter. 质谱是确定结构的仪器方法,最不同于本章讨论的其他方法。 It dose not depend on the selective absorption of particular frequencies of electromagnetic radiation but rather examines what happens to a molecule,when it is bombarded with high-energy electrons. 它不是依靠选择地吸收电磁波的部分频率, 而是检测一个分子被高能电子轰击时所发生 的变化。 核磁共振氢谱:核磁共振氢谱:

38、Proton nuclear magnetic resonance(1H-NMR) Chemists compare the shielding of protons in organic molecules by specifying their chemical shift relative to a standard substance.This substance is tertamethylsilane (TMS).The protons of TMS are more shielded than those of almost all organic compounds.In a

39、solution containing TMS, all the relevant signals apper to the left of the TMS peak. 化学家们将有机分子中的氢原子化学位移与一种标准物质中的氢相比, 并以此来比较该 分子中的氢所受的屏蔽。这种标准物质就是四甲基硅烷(TMS) 。TMS 的氢比几乎所有其他 的有机分子中的氢受到更多的屏蔽。在含有 TMS 的溶液中,所有相关信号都出现在 TMS 峰的左侧。 Peak positions are measured in frequency units (hertz) downfield from the TMS pe

40、ak.(Frequency units are more convient to use than units of magnetic field strength.The two sets of units are directly proportional to each other.) 其他质子峰的位置在 TMS 的低场处,以频率为单位进行测量。 (以频率为单位比用场 强为单位用起来更方便,并且,这两个单位直接互成比例。 ) By reporting chemical shift in parts per million,this effect of field strength is

41、taken into account:thus irrespective of magnetic field strength. 当化学位移以 ppm 表示时,磁场强度已经考虑在内,不需考虑仪器的场强。 The number of signals in a 1H nmr spectrum reveals the number of chemical shift nonequivalent protons in a molecule; the integrated areas tell us their relative ratios; their chemical shifts indicat

42、e the kind of environment surrounding the proton; and the splitting pattern is related to the number of protons on adjacent carbons. 在 1H 核磁共振光谱中,信号的数量表示一个分子中不等价值质子的化学位移的数量。 积分面积告诉我们它们的比率。 化学位移说明质子周围环境中的种类。 裂分图形与相邻碳上 的质子数量有关。 核磁共振核磁共振碳碳谱:谱:Carbon-13 nuclear magnetic resonance(13C-NMR) Carbon-13 chemical shifts cover a rang of over 200 ppm. In many substances a separate signal is observed for each carbon atom; and the chemical shifts are charatcteristic of particular structural types. 13C 的化学位移宽度大于 200ppm。在许多物质中,每个碳原子可观察到各自的信号。 化学位移与特定的结构类型有关。
