摘要
对从重齿毛当归（ＡｎｇｅｌｉｃａｐｕｂｅｓｃｅｎｓＭａｘｉｍｆ．ｂｉｓｅｒｒａｔａＳｈａｎｅｔＹｕａｎ）根及根茎中分得的１２种６－或８－脂代－７－氧－香豆素和８种二氢呋喃香豆素衍生物进行了１Ｈ和１３ＣＮＭＲ分析研究．结合文献．做出规律性总结．运用２ＤＮＭＲ技术．对文献中当归醇类化合物碳谱中的个别错误归属给予了纠正，并首次探讨了此类化合物的ＭＳ裂解途径．
Twelve 6 - or 8 -alkyl-7 -oxygenated coumarins and eight dihydrofuranocoumarins were isolated from the roots and rhizomes of Angelica pubescens Maximf. biserrata Shan et Yuan. Their spectral analysis (1H-, 13C NMR and MS) were discussed referring to some literature's about such kinds of compounds. Combined withthe technique of 2D NMR, some mistakes about carbon assignment of angelol-typecoumarins in literature were corrected.
