Abstract

A new 12a-dehydrorotenoid 1, 11-dihydroxy-9, 10-methylenedioxy-12a-dehydrorotenoid (1), together with a new isoflavonoid glycoside tectorigenin-7-O-beta-glucosyl-4'-O-beta-glucoside (3), were isolated and identified from the rhizomes of I. spuria (Zeal). In addition, 4 known compounds, tectorigenin (2) tectorigenin-7-O-beta-glucosyl (1 --> 6) glucoside (4), tectoridin (a tectorigenin-7-O-beta-glucoside) (5) and tectorigenin-4'-O-beta-glucoside (6) were isolated and identified for the first time from this plant. The structures of the isolated compounds were determined by spectroscopic methods (UV, IR, 1H, 13C-NMR, DEPT, HMQC, NOESY, and HMBC experiments and MS spectrometry) and by comparison with literature data of known compounds. Compounds 2, 4, 5, and 6 are reported for the first time from this plant through the present study.

摘要

从鸢尾（I. spuria (Zeal)）的根茎中分离并鉴定出一种新的12a-脱氢类胡萝卜素1, 11-二羟基-9, 10-亚甲二氧基-12a-脱氢类胡萝卜素（1），以及一种新的异黄酮苷鸢尾黄素-7-O-β-葡萄糖基-4'-O-β-葡萄糖苷（3）。此外，还首次从该植物中分离并鉴定出4种已知化合物，即鸢尾黄素（2）、鸢尾黄素-7-O-β-葡萄糖基（1→6）葡萄糖苷（4）、鸢尾苷（一种鸢尾黄素-7-O-β-葡萄糖苷）（5）和鸢尾黄素-4'-O-β-葡萄糖苷（6）。通过光谱方法（紫外、红外、1H、13C-NMR、DEPT、HMQC、NOESY和HMBC实验以及质谱分析）并与已知化合物的文献数据进行比较，确定了分离出的化合物的结构。通过本研究，化合物2、4、5和6首次从该植物中被报道。
