草苁蓉中2个单萜苷类化合物的NMR研究

NMR Characterization of Two Monoterpene Glycosides Isolated from Boschniakia rossica Fedtsch et Flerov

从草苁蓉75%乙醇提取物中分离得到了2个单萜苷类化合物,结合其理化性质,并通过1DNMR(1 H NMR,13 C NMR)及1 H-1 H COSY、HSQC、HMBC、NOESY等多种波谱学方法进行结构鉴定,鉴定2个化合物分别为β-D-glucopyranose 1-(3,7-dimethyl-2-trans-6-octa-dienoate)(化合物1)和6,7-dihydrofoliamenthoic acid diglucoside(化合物2),其中化合物1为新化合物,化合物2为第1次从列当科植物中获得.

Two compounds were isolated from the 75 EtOH extract of Boschniakia rossica Fedtsch et Flerov. The compounds were characterized as β-D-glucopyranose 1- （3,7-dimethyl-2-trans-6-octadienoate） （1） and 6,7-dihydrofoliamenthoic acid diglucoside （2） by 1H- and 13C NMR and 2D NMR techniques （i. e. , 1H-1H COSY, HSQC, HM- BC, and NOESY）. Compound 1 was found to be a new compound, while compound 2 was obtained from Orabanchaceae family for the first time.
