中文摘要	采用红外光谱三级宏观指纹鉴定的方法对刺五加不同部位根、茎、叶原药材及总苷提取物的红外光谱图进行了整体的分析。原药材谱图显示,根和茎谱图较为相似,主要体现草酸钙和淀粉特征峰,而叶的草酸钙特征峰几乎消失,淀粉特征峰的峰形也变得不明显。总苷提取物的一维谱图显示根、茎、叶在1602cm-1、1514cm-1、1452cm-1(苯环骨架振动)和1271cm-1(=C-O)附近均有特征吸收,因此,推测三者共有的成分为酚苷类化合物。二阶导数谱图给出叶在1656cm-1(黄酮的C=O)附近特征峰明显强于根和茎,说明叶中黄酮类成分高于根和茎。二维谱图在1350-1700cm-1波段根和茎均体现苯环骨架振动的五个自动峰1636cm-1、1600cm-1、1521cm-1、1462cm-1、1453cm-1,叶除了苯环骨架振动峰外还出现1656cm-1黄酮类成分的C=O振动,进一步证实叶中黄酮类成分高于根和茎。; In this paper,raw radix,stem and leaf and total glycoside extract of them of Acanthopanax senticosus Harms have been studied via the multi-steps IR macro-fingerprint method.The spectra of raw medicinal materials show that the spectra of radix and stem are similar and mainly show characteristic peaks of calcium oxalate and starch,whereas the characteristic peaks of calcium oxalate of leaf almost disappears and its shape of characteristic peak of starch also gets unconspicuous.FT-IR spectra of total glycoside extract of radix,stem and leaf present characteristic peaks at 1602cm-1,1514cm-1,1452cm-1(vibration of phenyl framework) and 1271cm-(1=C-O),therefore,we speculate that their mutual component is the compound of phenolic glycoside.Through observing second derivative IR spectra of total glycoside extract of different parts of Acanthopanax senticosus Harms,we find that the characteristic peak of leaf is stronger than that of radix and stem at 1656 cm-1(flavone C=O),it proves the quantity of component of flavone in the leaf is higher than that in the radix and stem.In two-dimensional correlation spectra,the radix and stem both have five automatic peaks(vibration of phenyl framework) at 1350-1700 cm-1,whereas the leaf still shows another automatic peak at 1656 cm-1(flavone C=O),it further proves the quantity of component of flavone in the leaf is higher than that in the radix and stem.Thus it can be seen IR macro-fingerprint technique can provide plentiful holistic information and hold general quality of Acanthopanax senticosus Harms.
