藤香树中二个新的脂肪硝基酚苷的鉴定藤香树中二个新的脂肪硝基酚苷的鉴定

Identification of the structure of two new nitro group phenolic glycosides from Schisandra propinqua (Wall.) Baill var. intermidia A.C.Smith

摘要: 目的研究藤香树Schisandra propinqua (Wall.) Baill var. intermidia A.C.Smith茎藤的化学成分。方法应用多种色谱技术进行分离纯化，根据化合物的理化性质和光谱数据分析鉴定结构。结果分离得到7个化合物，分别鉴定为6′-O-α-L-arabinofuranosylthalictoside (1), 6′-O-β-D-apiofuranosylthalictoside (2), thalictoside (3), icariside D₂(4)， prinsepiol (5), (+)-1-hydroxypinoresinol (6)和(+)-medioresinol (7)。结论化合物1和2为新的脂肪硝基酚苷化合物，其余均为首次从藤香树中获得。

Abstract: AimTo study the bioactive components from Schisandra propinqua (Wall.) Baill var. intermidia A.C.Smith. MethodsCompounds were separated with a combination of multi-chromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence. ResultsSeven compounds were isolated from the leaves of Helicia nilagirica. The structures were elucidated as 6′-O-α-L-arabinofuranosylthalictoside (1)， 6′-O-β-D-apiofuranosylthalictoside (2), thalictoside (3), icariside D₂ (4), prinsepiol (5), (+)-1-hydroxypinoresinol (6) and (+)-medioresinol (7). ConclusionTwo compounds are new nitro phenolic glycosides.
