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

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。

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

AIM: To study the bioactive components from Schisandra propinqua (Wall.) Baill var. intermidia A. C. Smith. METHODS: Compounds were separated with a combination of multichromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence. RESULTS: Seven compounds were isolated from the leaves of Helicia nilagirica. The structures were elucidated as 6'-O-alpha-L-arabinofuranosylthalictoside (1), 6'-O-beta-D-apiofuranosylthalictoside (2), thalictoside (3), icariside D2 (4), prinsepiol (5), (+)-1-hydroxypinoresinol (6) and (+)-medioresinol (7). CONCLUSION: Two compounds are new nitro phenolic glycosides.
